Lay your cinch flat and measure from one buckle tip to the other. If you have a mohair or blend cinch, pull it tight. I measure mine on my loom, which is the length they'll be on your horse. Mohair has some give but won't stretch, while synthetic materials do not give.

Cinches are usually measured in inches, English girths are measured in centimeters. Sometimes your horse may need a very specific length that mass produced makers don’t have. I can make a cinch to fit your horse - no matter the length.
