GIRTH SOLO PADDED

Padded cotton

Padded cotton dressage girth

Girths are measured from the end of the buckle to the end of the buckle (the full length) and vary in size by 2 inches (5cm)

If you don't have a tape measure on hand you can use a piece of string to get the needed length and measure the string afterwards.

If you don't have an old girth to measure, then you can measure for a new girth by placing your numnah and saddle on your horse, and measuring from halfway up the girth point, around the tummy, to halfway up the next girth point.
You ideally want to have 2 holes adjustment up, and 1 extra hole for adjusting down on the girth points.

As a very basic rule of thumb:
14-15 hands = 42 - 44"
15-16 hands = 46 - 48" GP girth and 26" dressage girth
16-17 hands = 48 - 54"
