Myler Bits fit a little different than traditional bits because they have a distinctive curve which allows more room for the tongue. In addition, a Myler Bit will measure 1/8 inch larger than the stated size because the Mylers want to make sure that the has at least 1/8 inch to 1/4 inch of bit on both sides of the mouth.
Choose the size nearest to your measurement, but go up, not down, to make sure that the bit won't be too tight.
If the bit fits properly, you should see at least 1/8 inch to 1/4 inch of bit on both sides of the mouth. Make sure the headstall is adjusted correctly and the bit is centered in his mouth.
There should also be some room between the cheekpiece and your horse's face because it can cause rubbing on the cheeks or lips. We always say like the thickness of your little pink would fit in between.
All horses have slightly different conformation, fleshy lips, a narrow muzzle or a heavy muzzle.
