Big Do Red-Eared Sliders Get in Captivity? | Red-eared sliders (Trachemys scripta elegans) are a popular species of pet turtle. They get their name from the red stripe that runs behind each ear. In the wild, these turtles can grow to be about 12 inches long.

But in captivity, they typically only reach about 8 inches in length. The smaller size is due to a lack of space and food availability in most captive environments.

Most pet red-eared slider turtles grow to be about 8-10 inches long. However, it is not uncommon for some red-eared sliders to reach 12 inches or more in length if they are well cared for and have plenty of space to grow. In the wild, these turtles can get even bigger, with some specimens reaching up to 18 inches in length!

So if you’re thinking about getting a pet turtle, be prepared for your little friend to potentially outgrow his or her home.

Red-eared slider turtles are one of the most popular turtle species kept in captivity. They are relatively easy to care for and can live a long time if properly cared for. One of the most common questions about red-eared slider turtles is “How big do they get?”.

The answer to this question depends on a few factors, including the sex of the turtle, whether it is wild caught or captive bred, and how well it is cared for. On average, male red-eared slider turtles will grow to be about 10-12 inches long while females will reach sizes of 8-10 inches. However, there are always exceptions to these averages and some individuals may grow larger or smaller depending on these factors.

One of the best ways to ensure that your red-eared slider turtle grows to its full potential size is to provide it with proper care and nutrition. A healthy diet and clean living conditions are essential for any turtle, but especially for young turtles who are still growing. If you provide your turtle with everything it needs, you can expect it to reach its full size potential!

How Big is a 1 Year Old Red Eared Slider?

When it comes to the size of a 1 year old red eared slider, there is really no definitive answer. This is because these turtles can vary quite a bit in size, depending on a few different factors. For example, turtles that are raised in captivity tend to be smaller than those that are raised in the wild.

Additionally, male turtles typically grow to be larger than females. So, while there is no exact answer to the question of how big a 1 year old red eared slider can be, we can give you some general guidelines. On average, these turtles will reach about 4-6 inches in length when they are 1 year old.

However, some may be even larger or smaller than this. Again, it just depends on the individual turtle and its unique circumstances.

How Long Until a Red Eared Slider is Full Grown?

A red eared slider can take between two and three years to reach full size. Females are generally larger than males, with some reaching up to 18 inches in length. The average lifespan of a red eared slider is 20-30 years, although some have been known to live for over 40 years in captivity.

Red Eared Sliders: What You Need to Know

How Long Do Red-Eared Sliders Live in Captivity

Red-eared sliders are a popular type of turtle that is often kept as a pet. They can live for 20-30 years in captivity if they are properly cared for. However, many turtles do not live nearly this long due to poor care and living conditions.

It is important to provide your turtle with a large tank or pond, plenty of places to hide, and clean water. A diet of fresh vegetables and pellets will help keep your turtle healthy and active. With proper care, your red-eared slider can be a fun and rewarding pet for many years to come!


Red-eared sliders are a popular type of pet turtle, and they can get pretty big in captivity! They can grow to be up to 12 inches long and weigh up to 10 pounds. That’s a lot bigger than the average wild red-eared slider, which only grows to be about 4 inches long.

Why do red-eared sliders get so much bigger in captivity? It’s probably because they have plenty of food and no predators to worry about. In the wild, these turtles have to compete with other animals for food, and they’re often eaten by larger predators.

So they don’t have the chance to grow as large as they do in captivity. If you’re thinking about getting a red-eared slider as a pet, be prepared for it to get pretty big! But don’t worry, they’re still relatively easy to care for.

Just make sure you have enough space for them to swim and bask areas, and give them plenty of food.
