All about the ancient tribes
Attach the saddle to your horse and sit down in the saddle. While riding, you should be able to fit 3 to 4 fingers in between the swell and your thigh. If you can fit more than 4 fingers, your saddle is too big. If you can’t fit 3 fingers, then your saddle is too small.
Measuring your Saddle Seat Size
If you are unsure of the right size for the gullet for your horse, you can measure your horse’s withers. Take a flexible-but-firm wire and place it over the horse’s withers two inches behind the horse’s shoulder blade, then bend it so it lays over the withers against the horse’s skin.
Here are six signs to watch for which could indicate that your saddle doesn’t fit your horse.
Place the saddle on the horse’s bare back (no pad). There should be two to three fingers space between the top of the wither and the gullet of the saddle. If you can fit your whole hand (vertically) between the bottom of the gullet and the wither, the tree is probably too narrow.
Place your hand into the space between the saddle and your horse’s wither, using your fingers to measure the vertical space. The gap should fit no more than two fingers to two and a half fingers. If three or more fingers fit, the gullet is too narrow. If fewer than two fingers fit, the gullet is too wide.
Scientists have measured sit bone spacing for large populations. On average, men’s sit bone width ranges between 100mm – 140mm (give or take a few mm to round), and women’s range between 110mm – 150mm.
Place the saddle on the horse’s bare back without a pad. There should be two to three fingers space between the top of the wither and the gullet of the saddle. If you can vertically fit your whole hand between the bottom of the gullet and the wither, the tree is probably too narrow.
