Knowing your horse’s weight is essential for proper feeding, medication dosing and overall health management.
Modern Horse
Unfortunately most of us don’t have access to a livestock scale. That’s where The Equinest Horse Weight Calculator comes in handy. This straightforward tool lets you estimate your horse’s weight using just two measurements: heart girth and body length, both entered in inches.
How it Works
To use it, you’ll need a soft, flexible tape measure. First, measure your horse’s heart girth by wrapping the tape around the barrel just behind the withers and elbows—essentially where your girth or cinch sits. Next, measure body length from the point of the shoulder to the point of the buttock.
Enter both numbers into the calculator and you’ll instantly receive an estimated weight!
Why it’s Useful
Why does this matter? Accurate weight information helps you calculate correct dewormer doses, determine appropriate feed amounts and monitor changes that might indicate health issues. Overestimating or underestimating weight can lead to under-dosing medications or overfeeding—both potentially harmful.
While a livestock scale remains the gold standard for precision, this calculator provides a reliable estimate when scales aren’t available. It’s a quick, practical tool every horse owner should bookmark.
