Measuring Your Horse's Mouth

Measuring your horse's mouth is an important part of finding the right bit.  All the bits in our online catalogue have a bit fitting table that will give the right size of bit for the width of the horse's mouth. 

Measuring this width is an easy procedure provided one knows what to look for. Using a bit measure or straight rod, put it in the horse's mouth and lift it to the correct place in the mouth - just before any wrinkles begin to form (Figure 1), and mark the bar on both sides just outside the lip crease.

Measuring between these marks gives you the measured mouth size.

You can measure a correctly fitting bit. To do this lay the bit flat and measure the distance between the insides of the cheekpieces (Figure 2). Be sure to include the type of mouthpiece and cheekpiece of the bit that you measured so that we can calculate the correct size of the new bit.
