What is the Leopard Gecko Growth Chart Tracker?
The Leopard Gecko Growth Chart Tracker plots weight and length over time against species growth curves for leopard geckos. Weight is one of the earliest and easiest signals of a health problem, both gradual weight gain and unexpected weight loss are worth catching early.
A well-cared-for leopard gecko usually lives somewhere between 15 and 20 years. As an insectivore, what a leopard gecko needs from its diet changes across its life stages. A single adult needs at least a 90x45cm floor area with a warm hide around 32C, a cool hide, and a humid hide to help shedding. Belly heat from a mat with a thermostat matters more than overhead heat. The usual suspects for this species are metabolic bone disease, retained shed on toes and eyes, impaction from loose substrate, so any noticeable change is worth following up.

How does the Leopard Gecko Growth Chart Tracker work?
The healthy range is drawn from breed or size-variant references for leopard geckos, adjusted for age where growth is still underway. Individual leopard geckos vary more than averages suggest, so read the number as a reference point rather than a measurement.
Factors that matter
- Breed or size variant: which sets a very different healthy range than a flat species-wide number would
- Age: growing juveniles are compared against a growth curve rather than an adult target
- Body condition: since two animals at the same weight can have very different amounts of muscle versus fat
- Spay/neuter status and activity level, both of which shift metabolic needs
How do you use the Leopard Gecko Growth Chart Tracker?
- Enter the current weight in whichever unit you use (lb, oz, kg)
- Pick your build for the species (Small or fine-boned, Average, Large or heavy-boned)
- Pick your life stage (Growing, Adult, Senior)
- Enter the age
- Press Calculate, then read the result alongside the sources listed below
Worth doing: jot down the date and the result each time. A single number tells you little, but a trend across a few months tells you a lot about your leopard gecko.

Before you rely on this
Averages hide a lot of variation. The figure here reflects what is typical for leopard geckos, but your leopard gecko may sit well outside it for perfectly ordinary reasons. Use the result to spot changes over time in your own animal rather than to compare it against other people's pets.
