Horse Weight Calculator
Estimate adult horse body weight from measurements.
Estimated body weight
477
kgIntroduction
Estimate an adult horse’s body weight from heart girth and body length. A scale is more accurate, and this formula is not designed to diagnose body condition or set a feeding plan. This is a planning calculation, not a feeding plan, stocking recommendation, diagnosis, or substitute for local agricultural or veterinary advice.
What is Horse Weight Calculator?
Measure heart girth behind the withers and body length from point of shoulder to point of buttock. The calculator applies a commonly used adult-horse measurement formula and reports an estimate in kilograms and pounds.

Worked example
Example: estimate adult horse weight from measurements
Inputs: Heart girth = 180 cm, Body length = 175 cm
- Measure heart girth and body length in centimetres.
- Apply girth² × length ÷ 11,880.
- Round the output as an estimate, not a scale reading.
The estimated body weight is about 477 kg; a livestock scale is more accurate.
Use cases
- Tracking a consistent measurement estimate over time
- Preparing a scale estimate to discuss with an equine professional
