Horse Weight Calculator

The horse’s weight serves as a basic guide to determine feeding requirements and to observe your horse’s health and condition. Weighing your horse on a scale is the most accurate way to determine your horse’s weight. The LMF Horse Weight Calculator offers another method to estimate your horse’s weight. Measure your horse’s heart girth and body length as shown on the illustrations, and enter the numbers in the indicated fields below.

Heart Girth
Measure your horse’s heart girth (circumference) by running the tape measure all the way around your horse 4″ behind its front legs. Please see image above.

Body Length
Measure your horse’s body length from the point of the shoulder to the point of the buttock in a straight line. Please see image above.
