Russian tortoises are fascinating creatures with a unique set of characteristics that make them a popular choice among reptile enthusiasts. Are you considering getting a Russian tortoise as a pet and wondering how big it can grow? Or maybe you already have one and want to know if you should expect a massive reptile to take over your living room? Either way, understanding the potential size of your Russian tortoise is an essential aspect of responsible pet ownership.
In fact, their small size and easy-to-care-for nature make them ideal pets for beginners. However, just how big can they get? To answer your curiosity, let’s deep dive and learn more about these fascinating creatures in this article.
Adult size
Russian tortoises are relatively small in size compared to other species of tortoises. They typically reach an adult size of 8-10 inches (15-25 cm) in length, with females being slightly larger than males. As adults, Russian tortoises weigh between 2 and 4 pounds. Their shell, also known as a carapace, is typically round in shape with a high domed top.
Moreover, the Russian tortoise (Agrionemys horsfieldii) is a small and hardy species of tortoise that is native to the arid steppes of Central Asia. These tortoises are well-known for their ability to survive in extremely dry and harsh climates and are famous pets due to their docile nature and relatively low-maintenance care requirements.
What should I feed my Russian tortoise to promote growth?
Feeding your Russian tortoises a well-balanced diet is essential to promote healthy growth and development. In their natural habitat, Russian tortoises primarily feed on a diet of grasses, weeds, and wildflowers, which should be the primary component of their diet in captivity as well. Here are some tips on what to feed your Russian tortoises to promote growth, according to our tortoise experts:
- Offer a variety of leafy greens, such as collard greens, kale, mustard greens, and dandelion greens. These provide essential nutrients, vitamins, and minerals necessary for healthy growth.
- Add in small amounts of fruits and vegetables, such as shredded carrots, squash, and apples. These can be given as occasional treats or mixed in with their regular diet.
- Provide high-quality commercial tortoise food, which is formulated specifically for their nutritional needs. Look for a product that contains a balanced blend of fiber, protein, and other essential nutrients.
- Offer calcium supplements, such as cuttlebone or calcium powder, to help support strong bones and healthy growth.
- Avoid feeding your tortoise high-fat or high-protein foods, as these can cause health problems and stunted growth.
Gender differences
While the sexes are similar in appearance, there are some distinct gender differences in Russian tortoise species. Fortunately, we have compiled several physical and behavioral differences between male and female Russian tortoises that can help determine their gender. Here are a few key differences:
| No. | Parameter | Male Russian Tortoise | Female Russian Tortoise |
| 1. | Size | It can only reach 5-8 inches in length. | It can reach up to 6-10 inches in length. |
| 2. | Tail | Longer, thinner tail, which is used during mating. | Shorter, thicker tail. |
| 3. | Plastron shape | It has a concave dip within its plastron. | It has a flat plastron. |
| 4. | Behavioral differences | Males may become more aggressive and vocal, and they may display courtship behaviors such as head bobbing and circling around females. | Females can be aggressive, but they usually give in eventually. |
| 5. | Cloacal opening | A male’s cloaca is longer and more slit-like. It is located in the last third of the tail, towards the tip. | A female’s cloaca is rounder and more star-shaped than the male’s. It is found much closer to her body, at the base of her tail where it joins her body, almost disappearing into the shell. |
What temperature should I keep my Russian tortoise’s enclosure?
Maintaining the proper temperature range in your Russian tortoise’s enclosure is crucial for their health and well-being. As ectothermic animals, they rely on external sources of heat to regulate their body temperature and metabolism. Here are some general guidelines for keeping your Russian tortoise’s enclosure at the appropriate temperature:
Ambient temperature
The ambient temperature of the enclosure should be maintained between 85-88°F (29-31°C) during the day and should not drop below 70°F (21°C) at night. A heat lamp or ceramic heat emitter can be used to maintain the ambient temperature. Use a thermometer to monitor the temperature in the enclosure and adjust the heating source as needed.
Basking spot
Provide a basking spot in the enclosure with a temperature range of 90-100°F (32-38°C). This area should be heated using a basking lamp or ceramic heat emitter. Be careful not to overheat the enclosure, as this can cause heat stress and other health problems.
Nighttime temperature
Russian tortoises require a cooler nighttime temperature range of 75-80°F (24-27°C). If the temperature drops too low, a low wattage heat lamp or ceramic heat emitter can be used to provide additional warmth.
Growth rate
Russian tortoises have a relatively slow growth rate, especially during the first few years of life. In fact, it takes up to 15-20 years for a Russian tortoise to fully grow. Russian tortoise hatchlings are typically around 1.5-2 inches (4-5 cm) in length and expand at a slow rate during their first year of life. In the following years, the Russian tortoise growth rate will be very slow, depending on their diet and living conditions. You can check the size tortoise age chart to make sure your pet grows normally or not.
Moreover, Russian tortoises may reach their sexual maturity at the age of 10 and reach 6 inches in length. When a female tortoise goes a length of around 6 inches and starts to lay eggs, it may lay up to five eggs at once. Once Russian tortoises reach adulthood (8-10 inches long), their growth rate slows down considerably, with only minor changes in size occurring over the remaining lifespan. Although they are slow growers, Russian tortoises have the potential to live for more than 40 years, with proper care and attention.
Are there any genetic factors that can affect the size of a Russian tortoise?
Yes, there are genetic factors that can influence the size of a Russian tortoise. Like all living organisms, the size of a Russian tortoise is determined by a combination of genetic and environmental factors. Here are a few examples of genetic factors that can affect the size of a Russian tortoise:
Parental genetics
The size of a Russian tortoise can be influenced by the size of its parents. If both parents are larger, the offspring may have a genetic predisposition to grow larger.
Species/subspecies
Russian tortoises belong to a complex of species and subspecies, and different subspecies can vary in size. For example, the Agrionemys horsfieldii tends to be smaller than the Testudo horsfieldii.
Genetic mutations
Rare genetic mutations can occur that result in a larger or smaller tortoise size. It’s important to note that environmental factors such as diet, living conditions, and temperature also play a significant role in genetic mutations.
Lifespan
Since Russian tortoises are relatively easy to care for, they often live for more than 40 years. However, in captivity, they can live even longer. With proper care, a Russian tortoise can live for several decades. Some Russian tortoises have been known to live up to 100 years, although this is rare.
According to a study from Science Advances Journal, gender can also play a role in the lifespan of Russian tortoises. Females tend to have longer lifespans than males, possibly due to the stresses of breeding and territorial behavior in males. Additionally, the lifespan of a Russian tortoise can be influenced by genetic factors, with some individuals having the predisposition to live longer than others.
Can the size of a Russian tortoise impact its susceptibility to certain health issues?
Yes, the size of a Russian tortoise can impact its susceptibility to specific health issues. Smaller tortoises are more prone to respiratory infections. It is also more challenging to diagnose health issues in smaller tortoises due to the size of their organs and the difficulty of performing diagnostic tests. Moreover, smaller Russian tortoises are more likely to have problems with growth and development due to a lack of nutrients in their diet.
On the other hand, larger Russian tortoises are more likely to become obese. The larger than regular size can lead to health issues such as metabolic bone disease, respiratory infections, and shell problems. As a pet owner, you have to make sure that they have an ideal size, as it will also prevent health problems.

Vitamin supplements can also be added to the diet to ensure that the tortoise is getting all the necessary nutrients for growth. We recommend you give the Russian tortoise multivitamin that contains vitamins A and C.
Enclosure size
When it comes to housing a Russian Tortoise, size is a crucial factor in its growth and development. Russian tortoises require a large enclosure to ensure proper growth and overall health. In fact, these typical home reptiles can grow up to 8 to 9 inches in length. Therefore, the enclosure for tortoises should be at least 10 times longer, 5 times wider, and 3 times higher than the tortoise (approximately 40-50 gallons).
Moreover, it’s crucial to ensure that the enclosure has a substrate that is safe for the tortoise to walk on, such as coconut coir or orchid bark. The enclosure should also have hiding places, a shallow water dish for soaking, and a basking area with a heat lamp.
Environmental conditions
In the wild, Russian Tortoises inhabit a variety of habitats, from deserts to grasslands and even forests. They prefer well-drained, sandy soils and can be found living in burrows or burrows under vegetation. To provide the best environment for a Russian Tortoise, you should maintain environmental conditions that mimic its natural habitat as closely as possible. Let us give you some tips for keeping the appropriate environmental conditions for a Russian tortoise:
Temperature
The basking area of the enclosure should be maintained at a temperature of 90-100°F during the day, with a cooler area of the enclosure kept at 85-88°F. At night, the temperature can drop to 75-80°F. Use a thermometer to monitor the temperature and make adjustments as necessary.
Lighting
Russian tortoises require UVB lighting to help them synthesize vitamin D3, which is essential for their growth and overall health. Use a UVB light that provides a minimum of 10% UVB, and replace the bulb every 6-12 months.
Humidity
Russian tortoises require a moderate level of humidity, around 40-50%. To maintain this level of moisture, provide a shallow water dish for soaking, mist the enclosure regularly, and provide a substrate that retains some moisture.
Substrate
The substrate should be safe for the tortoise to walk on, such as coconut coir or orchid bark. Avoid using substrates that are too dry, such as sand or gravel, as these can cause respiratory problems.
Enclosure size
Russian tortoises require a large enclosure to ensure proper growth and exercise. See my previous tips for guidelines on enclosure size based on the size of your tortoise.
