Frequently Asked Questions

Why use a calculator instead of a weigh tape?

While weigh tapes are convenient, using heart girth and body length measurements in a formula is generally more accurate for horses of different shapes and sizes.

How do I measure body length?

Measure in a straight line from the point of the horse's shoulder to the point of the buttock (tuber ischii).

Is weight important for feeding?

Yes. Forage and hard feed requirements are usually calculated as a percentage of the horse's body weight to ensure they receive adequate nutrition.

Should I weigh my horse regularly?

Yes, ideally once a month. This helps you spot gradual weight changes that might indicate health issues or the need to adjust their diet.
