All you need is two rubber bit guards and a dowel rod or the handle of a wooden spoon, large enough to hold the bit guards steady but small enough for you to be able to move them.
Place the dowel or spoon gently in your horse’s mouth where the bit would normally sit. The goal is for it to rest in the corners of the lips without creating wrinkles.
Once it’s in position, slide the rubber bit guards up so they sit flush against each side of the lips. This helps mark the exact space the bit would occupy. The rubber guards will stay where you place them, making it much easier to get an accurate measurement at home.
Remove the rod/spoon and measure the distance between the inside edges of the rubber guards. That’s your horse’s approximate bit size.
