How Big Does A Leopard Gecko Get?

Table of Contents

Leopard geckos are a popular choice among reptile enthusiasts due to their small size and docile nature. These lizards are native to the deserts of Pakistan and northwestern India, and they are known for their unique patterned skin and their ability to climb walls and ceilings. 


One of the most common questions asked by potential leopard gecko owners is “how big do they get?” A leopard gecko can grow to be around 8-10 inches long, with males typically being larger than females. Their tail can make up about half of their total length.


In this article, we will explore the growth and size of leopard geckos and what to expect as your pet grows.


What Is The Average Size Of An Adult Leopard Gecko?

The average size of an adult male leopard gecko is around 8-10 inches in length from head to tail. They can weigh between 45-65 grams.


The average size of an adult female leopard gecko is around 7-9 inches in length from head to tail. They can weigh between 35-55 grams.


It is important to note that there can be variations in size and weight depending on the individual gecko and its genetics.


What Are The Factors That Affect Leopard Gecko Growth?

  • Nutrition: Proper nutrition is one of the most important factors that affect leopard gecko growth. A diet that is rich in protein, vitamins, and minerals is essential for healthy growth and development. Feeding your leopard gecko a diet that is high in calcium and low in phosphorus is also important for preventing metabolic bone disease.


  • Temperature: Temperature plays a crucial role in leopard gecko growth. Leopard geckos require a warm environment in order to properly digest their food and metabolize nutrients. A basking spot of around 90-95 degrees Fahrenheit and a cooler area of around 75-80 degrees Fahrenheit is ideal for leopard geckos.


  • Lighting: Leopard geckos require UVB lighting to properly absorb calcium and maintain healthy bone growth. A UVB light should be provided for at least 10-12 hours per day.


  • Genetics: Genetics plays a significant role in leopard gecko growth. Some leopard geckos may have a genetic predisposition to grow larger or more slowly than others.


  • Stress: Stress can negatively impact leopard gecko growth. Stress can come from a variety of sources, including poor living conditions, lack of hiding spots, or handling too frequently.


  • Age: Age also plays a role in leopard gecko growth. Leopard geckos will grow the fastest during their first few years of life, and growth will slow down as they reach maturity.


  • Health: A leopard gecko’s overall health will also affect its growth. Any underlying health issues such as parasitic infections, metabolic bone disease, or respiratory infections can slow down growth and development.


How To Measure Your Leopard Gecko

Measuring your leopard gecko is an important part of monitoring its health and growth. Here is a step-by-step guide on how to properly measure your leopard gecko:

  • Gather your materials: You will need a soft tape measure or a flexible ruler, a notebook or piece of paper to record your measurements, and a treat or food to coax your leopard gecko into staying still for the measurement process.
  • Measure the length: Start by measuring the length of your leopard gecko from the tip of its nose to the tip of its tail. Gently place the tape measure or ruler next to your leopard gecko and slowly extend it until it reaches the end of its tail. Record this measurement in your notebook or on a piece of paper.
  • Measure the width: Next, measure the width of your leopard gecko by placing the tape measure or ruler across its widest point, typically across its hips. Record this measurement in your notebook or on a piece of paper.
  • Measure the weight: Finally, measure the weight of your leopard gecko using a digital scale. Place your leopard gecko on the scale and carefully record the weight in your notebook or on a piece of paper.
  • Repeat the process: It is important to measure your leopard gecko regularly, such as every month, to track its growth and monitor any changes in its size or weight.


It’s important to note that it’s not recommended to hold your leopard gecko for measurement. Instead, use a soft tape measure and place it next to the gecko, this way you’ll have a more accurate measurement and your gecko will be less stressed.



In conclusion, a leopard gecko can grow up to 9-10 inches in length, with males typically being larger than females. However, proper care and nutrition can help ensure that your leopard gecko reaches its full potential in size. It’s important to provide a proper diet, adequate lighting, and a comfortable habitat to ensure that your gecko is healthy and can grow to its maximum size.
