A good fit
- Width: about 1/4" of mouthpiece should show on each side of the mouth. Measure across the mouth at the corners, or check the size on a bit that fits now.
- Height: adjust the headstall so the bit makes one or two soft wrinkles at the corners of the mouth.
- Curb strap: fit two fingers between the strap and the chin. It should engage when the shanks rotate back about 45 degrees.
- Leverage: longer shanks and a longer purchase give more leverage, so match the bit to your horse's training.

Questions, answered
What size bit do I need?
Most Quarter Horses take a 5" mouthpiece, smaller horses and Arabians 4 3/4", ponies 4" to 4 1/2" and minis 3 1/2" to 4". About 1/4" should show on each side of the mouth. Measure across the mouth at the corners, or check the size on a bit that fits now.
How do I choose a Western bit?
Start with a snaffle for young horses and direct rein work, move to a transition bit like a Tom Thumb or junior cowhorse, then to a shank bit for neck reining and finished horses. Longer shanks and higher ports add leverage and signal, so match the bit to your horse's training.
Do shank bits need a curb strap?
Yes. Shank and gag bits work with a curb strap or chain. Adjust it so two fingers fit between the strap and the chin.
Why sweet iron and copper?
Sweet iron oxidizes to a sweet taste and copper encourages salivation, which helps a horse accept and soften to the bit.
What do the Cowboy Tack levels mean?
Cowboy Tack sorts its bits into five levels to help match a bit to your horse's stage of training, from Level One for horses early in training to Level Five for finished horses.
Can I return a bit?
No. For hygiene reasons, bits are not eligible for return or exchange. Please check the size guide and measure before you order, and use Ask a question if you are not sure which size or mouthpiece to choose. See our Shipping & Returns page for details.
