If you use this method and either go to a tack shop or send in your measurements to a saddlery you can at least get close:
| Go to the hardware store and get about 4’ of 12 or 14 gauge house wire (the kind electricians use to wire a house) and cut it in half. This was written for Western saddles but the principle is the same for English or Australian. |
Take 2’ and shape it over your horse’s withers. Take the other 2’ and shape it over the center of his back.
Carefully take the wires and trace the inside of the wire on a heavy piece of cardboard (or poster board if you have it). Cut out the cardboard shapes and take them to the saddle shop to fit against some saddles.
Doing it any other way is guess work. If you can't take your horse to a tack shop, the next best thing is to take his proper measurments.
