Weight tape estimates are typically ±3–5% for average light breeds. Confirm with a scale for medication dosing.
Measurement Guide

Body Length
Measure in a straight horizontal line from the point of the shoulder to the point of the buttock. Do not follow the curve.
Summary
Enter heart girth and body length measurements to estimate your horse's weight using the standard weight tape formula.
How it works
- Choose your preferred unit system: inches/pounds or centimeters/kilograms.
- Measure heart girth: wrap a soft tape snugly around the horse just behind the front legs at the girth groove.
- Measure body length: from the point of the shoulder to the point of the buttock in a straight line.
- Enter both measurements and click "Estimate Weight".
- The estimated weight appears instantly along with a body condition note.
- For medication dosing, always confirm with a licensed veterinarian.
Use cases
- Estimating dosage weight for deworming pastes and oral medications.
- Tracking weight trends over weeks without a livestock scale.
- Feed ration planning when precise scale weight is unavailable.
- Pre-purchase screening to estimate condition and size.
- Teaching equine science students how weight tape formulas work.
- Remote barn management where hauling to a scale is impractical.
