What is the Pony Growth Chart Tracker?
The Pony Growth Chart Tracker plots weight over time against breed growth curves for young ponies. 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.
Expect roughly 25-35 years with a pony, which is worth factoring into any long-term plan. Diet-wise they are a herbivore, which shapes almost every feeding decision you make. Ponies are hardier and far more feed-efficient than horses, which makes them prone to obesity and laminitis on good pasture. They typically need restricted grazing rather than supplementary feed. Keep an eye out for laminitis, equine metabolic syndrome, sweet itch. These are the conditions ponies are most commonly seen for.

How does the Pony Growth Chart Tracker work?
The healthy range is drawn from breed or size-variant references for ponies, adjusted for age where growth is still underway. Treat the result as a well-founded estimate. Every pony is an individual, and your vet's judgement outranks any online tool.
What changes the answer
- 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 Pony 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
If two people care for your pony, agree on one method and stick to it. Half of all confusing results come from measuring differently each time.

Before you rely on this
Averages hide a lot of variation. The figure here reflects what is typical for ponies, but your pony 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.
