Ball Python Weight and Size Guide

Are you thinking about keeping a ball python as a pet, or do you currently have one and want to find out more about how they mature and change through time? Because of their manageable size and laid-back demeanor, ball pythons are among the most popular choices for individuals who have never owned a snake before.

As is the case with any pet, it is essential to have a solid grasp of the animal’s development and weight in order to give it with the appropriate level of care as well as the environment it requires. In the next article, we will present a basic reference to the size and weight of ball pythons at various times of their life, including when they are young, adult, and mature.

This article will assist you in better understanding your ball python and ensuring that they are healthy and thriving, regardless of whether you are a new owner or an experienced snake lover.

how big are hatchlings (babies)

Ball python hatchlings are relatively small compared to their adult counterparts. They typically measure around 10 inches (25 cm) in length and weigh between 40-70 grams. At this stage, they are fragile and require a lot of care and attention to ensure they are healthy and developing properly.

It’s important to provide hatchlings with the proper environment, including a small enclosure with appropriate temperature and humidity levels, and a diet consisting of appropriately-sized prey items.

As they grow, hatchlings will shed their skin frequently, which is a normal part of their growth process. With proper care, ball python hatchlings can grow into healthy and beautiful adult snakes.

How Big are Ball Python Juveniles?

Juvenile ball pythons are larger than hatchling ball pythons, however they are still rather little in comparison to adult ball pythons.

Juveniles typically reach their full length of between 2-3 feet (60-90 cm) and their full weight of between 200-400 grams by the end of their first year.

In comparison to when they were hatchlings, juveniles may begin to display more distinct markings and colors at this point in their development.

Because they will continue to lose their skin on a regular basis as they develop, it is essential to supply them with sufficient room as well as the environmental conditions that are ideal for their growth, such as the ideal amount of temperature and humidity.

The development and growth of juvenile ball pythons is dependent on their consumption of prey items that are proportionately large to them.

Juvenile ball pythons have the potential to continue to flourish and mature into their full adult size if they receive the appropriate care and diet.

How Big are Subadult Ball Pythons?

Ball python subadults are considerably bigger than juveniles but have not yet reached their full adult size.

At this point in their development, they have normally reached a length of between 3 and 4 feet (90 and 120 cm) and can weigh anything from 500 grams to 1.5 kilograms.

Subadults have evolved distinctive colors and markings, the appearance of which can change based on the particular morph or genetic features that each individual possesses.

Because they will continually shed their skin as they develop, regular care is essential to maintain healthy growth. They will continue to shed their skin as they mature.

This includes giving enough room, the right environmental conditions, and a well-balanced diet that contains prey items of the suitable size.

Subadult ball pythons have the potential to continue their growth and eventually achieve their full adult size and weight if they receive the appropriate care and diet.

How Big are Adult Ball Pythons?

The greatest size category for this particular kind of snake is comprised of mature ball pythons. Adult ball pythons will typically measure between 3 and 5 feet (90 and 150 centimeters) in length and can weigh anywhere from 1 to 5 kilos, depending on their gender, the genetic characteristics they inherit, and the circumstances in their surroundings.

Male ball pythons are often smaller and lighter in weight compared to their female counterparts. Adult ball pythons have completely developed colour and patterns by this point, which makes them attractive and beautiful animals to look at.

Adult ball pythons need to be given the proper care in order to keep their health and well-being in good condition.

This care must include the provision of a sufficient cage, acceptable temperature and humidity levels, and a balanced diet consisting of prey items of the appropriate size.

Adult ball pythons may survive for many years if they are given the necessary care and attention, and they make fantastic pets for snake aficionados of all skill levels.

How big can they get?

Although it is possible for ball pythons to reach lengths of up to 6 feet (180 cm) in the wild, this is an extremely uncommon occurrence.

The majority of ball pythons that are kept in captivity will not grow longer than 5 feet (150 cm), with the typical adult size being somewhere between 3 and 4 feet (90-120 cm).

The maximum weight of an adult ball python can range anywhere from one kilogram to five kilograms, however this number might shift based on factors such as gender and genetic characteristics.

It is important to keep in mind that individual ball pythons can deviate from these broad standards for size and growth, depending on a variety of factors including nutrition, genetics, and the circumstances in their environment.

To guarantee that your ball python may expand and develop in a way that is both healthy and pleasant for it, it is essential, however, to offer sufficient room as well as the appropriate environmental conditions.

Difference between male and female ball pythons

There are a number of variations, both in terms of appearance and behavior, between male and female ball pythons. The following are some of the more important ones:

Female ball pythons are often bigger and heavier than males, with females reaching lengths of up to 5 feet (150 cm) and males reaching lengths of up to 4 feet (120 cm). Size: Female ball pythons may grow to a maximum length of up to 5 feet (150 cm) (120 cm).

Head Form: Male ball pythons have heads that are smaller and more angular than those of females, who have heads that are bigger and more rounded.

The tails of male ball pythons are often longer and thicker than those of females, which are typically shorter and more slender.

The behavior of male ball pythons is characterized by a tendency to be more inquisitive and energetic than females, whilst females are often more submissive and quiet.

When it comes to reproduction, females are the only ones who are able to deposit eggs after achieving sexual maturity. Males do not lay eggs.

On the underside of their tails, males also have hemipenes, which are reproductive organs. These structures are visible to the naked eye.

It is essential to keep in mind that these distinctions may not be observable in certain individual ball pythons, and hence they should not be relied upon as the only method for distinguishing between male and female snakes.

The sex of a ball python can be more accurately determined with the assistance of a knowledgeable breeder or a qualified veterinarian who specializes in reptiles.


The look of ball pythons is unlike that of any other species of snake, which helps to differentiate them from one another.

They have a stocky physique, but their head and eyes are on the smaller side, which contributes to their “cute” appearance and makes them appear to be less dangerous.

The individual’s genetic make-up determines the coloration and patterning of the tiny, smooth scales that cover their skin. These scales can have a range of colors and patterns.

There is a diverse spectrum of colors and patterns that can be seen on ball pythons, from blatant black-and-white stripes to sophisticated, multicolored motifs.

Because of their ability to roll up into a tight ball with their head tucked in, they are often referred to as “ball pythons,” which is where the name originates from.

In general, the ball python is a stunning and intriguing species that, for those individuals who are interested in snakes, is an excellent choice for a pet.

Enclosure needs Quickshot

When it comes to housing a ball python, it is essential to give them with an enclosure that is suited for them and fits the requirements that are unique to them. While constructing an enclosure for a ball python, the following are some considerations to keep in mind:

Size is important because ball pythons require adequate space to be able to move about freely. A good rule of thumb is to offer a tank for an adult ball python that is at least 40 gallons in size and has dimensions of 36 inches by 18 inches by 18 inches. It is possible to put hatchlings and juveniles in smaller cages, and then progressively update these habitats as the animals get bigger.

Aspen bedding, cypress mulch, or coconut coir are all examples of good substrates to use since they are able to keep moisture levels stable and are simple to clean.

Temperature and Humidity: Ball pythons require an enclosure that has a warm side with temperatures ranging from 88 to 92 degrees Fahrenheit (31 to 33 degrees Celsius) and a cool side with temperatures ranging from 75 to 80 degrees Fahrenheit (24 to 27 degrees Celsius). In addition, the enclosure should have a humidity level ranging from 50 to 60 percent, which may be achieved by spraying the substrate with water and supplying a bowl of water.

Hidden Places: In order to feel safe, ball pythons enjoy having places where they may conceal themselves, such as a hide box or a piece of cork bark.

Lighting: While ball pythons do not require UVB illumination, a low-wattage heat bulb or ceramic heat emitter can be used to maintain the optimum temperature in their enclosure.

To avoid the growth of bacteria and to ensure that your ball python continues to enjoy good health, it is essential to do routine cleaning and disinfection of the enclosure. You can help guarantee that your ball python lives a long, healthy, and happy life for many years to come by providing it with a habitat that is acceptable and pleasant for it.


Although ball pythons are largely nocturnal and do not require UVB illumination in order to synthesis vitamin D3, they do not have the same requirements as other reptiles, who do have these requirements.

They do, however, need a heat source in order to maintain a consistent temperature throughout their bodies. This heat source can be given by a heat bulb with a low wattage or by a ceramic heat emitter.

This allows the ball python to thermoregulate and migrate between different temperatures as required. The heat source should be positioned on one side of the enclosure to create a temperature gradient with a warm side and a chilly side.

It is essential to provide ball pythons a day and night cycle, which may be accomplished by giving them a light cycle that alternates between 12 hours of light and 12 hours of darkness.

This may be done by using a white light bulb with a low wattage or by simply letting natural daylight inside the enclosure. Both methods are viable options.

As compared to the lighting needs of other reptiles, the lighting requirements for ball pythons are rather straightforward. They are able to survive in their cage without the requirement of any extra illumination so long as they have access to an adequate source of heat and a day/night cycle.

Temperature needs

Ball pythons are native to the tropical regions of Africa, where they typically experience warm temperatures year-round.

In captivity, it’s important to provide ball pythons with a temperature gradient within their enclosure, which allows them to thermoregulate and maintain a healthy body temperature. Here are some temperature guidelines for ball pythons:

  1. Warm Side: The warm side of the enclosure should be maintained at a temperature of 88-92°F (31-33°C) during the day, with a basking spot that can reach up to 95°F (35°C). This temperature range is important for proper digestion and metabolism.
  2. Cool Side: The cool side of the enclosure should be maintained at a temperature of 75-80°F (24-27°C) during the day, with a temperature drop at night to simulate natural temperature fluctuations.
  3. Heating Source: A low-wattage heat bulb or ceramic heat emitter can be used to provide heat to the enclosure. The heat source should be positioned on one side of the enclosure to create the temperature gradient.
  4. Temperature Monitoring: It’s important to regularly monitor the temperature within the enclosure using a thermometer or temperature gun to ensure that the temperatures are within the appropriate range.

It’s also important to note that ball pythons are sensitive to sudden changes in temperature and should not be exposed to temperatures below 70°F (21°C) or above 95°F (35°C).

By providing a suitable temperature gradient within the enclosure, you can help ensure that your ball python stays healthy and comfortable.


Choosing the right substrate is important when setting up an enclosure for your ball python, as it can affect their comfort, health, and hygiene. Here are some common substrates used for ball pythons:

  1. Aspen Bedding: This substrate is made from shredded aspen wood, which is a good choice for ball pythons as it helps maintain humidity levels and is easy to spot-clean.
  2. Cypress Mulch: Cypress mulch is a popular choice for ball pythons as it holds humidity well, has natural antimicrobial properties, and can be spot-cleaned easily.
  3. Coconut Coir: Coconut coir is made from coconut husks and is an eco-friendly option for substrate. It’s also a good choice for ball pythons as it holds humidity well, is easy to spot-clean, and can be used for a long time.
  4. Paper Towels or Newspaper: These substrates are inexpensive and easy to change frequently, making them a good choice for hatchlings and sick or injured snakes.

When selecting a substrate, it’s important to avoid substrates that can cause respiratory issues or impactions, such as sand or gravel. It’s also important to maintain a clean and hygienic environment by spot-cleaning and replacing the substrate regularly. By providing a suitable substrate, you can help ensure that your ball python stays healthy and comfortable in their enclosure.


The addition of decorations to the cage of your ball python might assist to create an atmosphere that is more natural and interesting for the snake. The following is a list of several kinds of decorations that you might put to the enclosure of your ball python:

Ball pythons want a place to hide in order to feel safe and to lower their stress levels; therefore, it is vital for the enclosure to contain at least one and preferably more than one hide box. Hides may be crafted from a wide range of materials, including wood, plastic, and even natural materials such as the bark of cork trees or the shells of coconuts.

Branches: Providing your ball python with branches or other climbing structures might provide it with a place to climb and explore its environment. You may use natural branches, artificial vines or branches made of materials like plastic or silicone, or even a combination of the two.

Rocks: Including rocks or other natural components in the cage can help to provide a more lifelike atmosphere and offer your ball python with places to climb and bask.

Fake Plants: The addition of artificial plants or foliage to the cage may make it more aesthetically beautiful while also providing your ball python with places to hide or investigate.

When adding decorations to the cage of your ball python, it is crucial to make sure that the decorations are secure and do not present a risk of being injured or ingested by the ball python.

While decorating, try to avoid using anything with jagged edges or little bits that may easily be ingested.

In addition, it is essential to ensure that any decorations are routinely cleaned and disinfected in order to provide a sanitary environment for your ball python.

You may make your ball python’s habitat interesting and exciting by using the appropriate decorations, which will assist you in maintaining the animal’s good health and happiness.


It is essential for the health and well-being of your ball python to maintain its enclosure in a clean state at all times. The enclosure of a ball python should be cleaned according to the following guidelines:

Spot cleaning is removing feces and contaminated substrate as soon as possible in order to keep the hygiene level high and avoid the growth of bacteria. It is important to perform spot cleaning on a regular basis, preferably once per day or as required.

Complete Cleaning: At the very least once every month, the enclosure has to undergo a comprehensive cleaning. Take your ball python and all of the decorations and substrate out of the cage, and then use a disinfectant that is suitable for reptiles to wipe all of the surfaces. Before adding new substrate and decorations, give the cage a thorough cleaning with water and allow it to dry up fully beforehand.

Cleaning and refilling the water bowl on a regular basis or as needed to avoid the formation of germs is required for the water bowl.

While handling your ball python, be sure to wash your hands both before and after, as this will help avoid the transmission of bacteria.

If you are going to bring a new ball python into your home, you should quarantine it in a separate enclosure for at least a month before bringing it inside. This will help prevent the introduction of any potential diseases or parasites.

While cleaning the cage for your reptile, it is imperative that you use a disinfectant that is appropriate for reptiles, since common home cleaners may be harmful to them. After cleaning the enclosure, it is essential to check the temperature and humidity levels to verify that they are within the range that is optimal for the health and happiness of your ball python.

Food and water needs

Your ball python’s health and well-being depend on you providing it with the appropriate nutrients and hydration at all times.

The following are some suggestions to follow when it comes to giving your ball python with food and water:

Feeding: Since ball pythons are carnivores, the majority of their diet consists of rodents like mice and rats. Your ball python’s age and size will determine the amount of food it requires and how often it should be fed.

While they are hatchlings and juveniles, ball pythons should be given food that is the proper size every five to seven days, but when they are adults, they can be fed larger prey every seven to ten days.

In order to avoid injuring your ball python when feeding it, it is essential to utilize food that has already been killed or to euthanize live prey in a compassionate manner.

Wild-caught food should be avoided as a source of nutrition for your ball python due to the risk of the presence of parasites and illnesses.

Water Always have a dish of clean, filtered water available within the cage for the animals to drink from.

Ball pythons will sip water from the bowl provided, and they may also soak in the water in order to stay hydrated and speed up the shedding process.

The water should be changed every day, and the bowl should be cleaned and sanitized on a regular basis.

If they are given a meal that is well-balanced and consists of prey that is the suitable size for them, ball pythons do not need any additional supplements. On the other hand, if you are concerned about the nutritional value of the food that you give your ball python on a regular basis, you may give them calcium supplements once a month.


Handling your ball python can be a rewarding and enjoyable experience, but it’s important to handle them properly to ensure their safety and comfort.

  1. Wait until your ball python is fully acclimated to their enclosure before handling them. This can take a few days to a few weeks, depending on the individual snake.
  2. Approach your ball python calmly and confidently, avoiding sudden movements or loud noises that may startle them.
  3. Support the weight of your ball python with both hands, using one hand to support the front of their body and the other to support the back.
  4. Avoid handling your ball python for extended periods of time or too frequently, as this can cause stress and potentially lead to health issues.
  5. Avoid handling your ball python after they have eaten, as this can cause regurgitation.
  6. Wash your hands before and after handling your ball python to prevent the spread of bacteria.
  7. Monitor your ball python’s behavior during handling and watch for signs of stress, such as hissing, biting, or attempting to escape. If your ball python seems stressed, gently return them to their enclosure and try again later.

Common Health Issues

The following is a list of some of the more prevalent health problems that can plague ball pythons:

Infections of the Respiratory Tract Respiratory infections are a common health problem in ball pythons and can be caused by environmental factors such as a filthy cage, low humidity, or inadequate ventilation. The symptoms of this condition include wheezing, a runny nose, and difficulty breathing.

Ball pythons are susceptible to a variety of internal and external parasites, including mites, ticks, and tapeworms. The indications and symptoms of this condition are easily recognizable and include fatigue, lack of appetite, and the presence of parasites.

Mouth Rot: Mouth rot, sometimes called infectious stomatitis, is a bacterial infection that mostly affects the mouth but has the potential to spread to other regions of the body as well. Around the mouth, symptoms include puffiness, redness, and drainage from the affected area.

Issues with Shedding Ball pythons naturally shed their skin on a regular basis; however, shedding difficulties can arise if the ball python’s cage is too dry or if the snake is not given with sufficient moisture to assist in the shedding process. A retained eye cap, incomplete shedding, and skin discomfort are all symptoms of this condition.

Overfeeding can create obesity in ball pythons, which can lead to a variety of health problems in the animal, including fatty liver disease, respiratory troubles, and a shortened lifespan. Obesity also shortens the animal’s overall lifetime.


The cost of a ball python can change significantly based on a number of characteristics, including its age, color, pattern, and genetics. The following is a list of some standard pricing ranges for ball pythons:

Hatchlings: The price of a ball python hatchling can range anywhere from $50 to $100 on average.

Prices for juvenile ball pythons, which are typically between one and two years old and range from one hundred to two hundred and fifty dollars.

Adults: The price of an adult ball python can range anywhere from $150 to $500, depending on the genetics of the animal and how rare it is.

Ball pythons with distinctive coloration and patterning are referred to as “designer morphs,” and these animals can command a higher price. The cost of a designer morph might run anywhere from several hundred dollars to several thousand dollars.


For skilled reptile keepers, breeding ball pythons may be a lucrative and thrilling experience. Ball pythons are a kind of boa. Having said that, it is essential to have a solid understanding of the obligations and potential obstacles that come along with breeding. The following are some pointers to keep in mind when breeding ball pythons:

Age and Health: Before being used for breeding, ball pythons should be at least three to four years old and in good condition. Weight requirements for females are a minimum of 1200 grams, while weight requirements for boys are a minimum of 700 grams.

Ball pythons normally give birth to their young in the springtime, as this is the time of year when temperatures are at their warmest. It is vital to offer a cooling phase of around 60–90 days, during which the temperature in the enclosure is progressively dropped, in order to stimulate breeding. This will take place.

Setup for Breeding: A separate enclosure should be built up for breeding, including a good hiding area for the female and a heat source to maintain a correct temperature gradient. This should be done before the female is introduced into the enclosure. In addition to this, the enclosure has to have its humidity levels checked regularly.

Incubation of Eggs When the female has finished laying her eggs, they should be retrieved and placed in an incubator that has a substrate that is appropriate for development as well as temperature and humidity conditions that are optimal for growth.

Caring for the Hatchlings Once the hatchlings have emerged from their eggs, they should be placed in separate cages that have the right heating and feeding schedules for them.
