Bit Guide: How to Choose the Right Bit

Choosing a bit can feel confusing. This guide explains our bits in simple words, so you can find the right one for your horse. We make every bit ourselves, in any size you need. If you're still unsure, message us and we'll help.

Important: every horse is different, and no bit fixes every problem. Always start with the mildest bit that works, and check your competition rules before showing.

Start here: what's your horse doing?

"My horse is young or green, and still learning to steer"

Choose a full cheek. The cheeks gently guide the face for clearer steering, and the bit can't slide through the mouth.

"My horse is sensitive and fusses with the contact"

Choose a bit that stays steady and quiet in the mouth.

"I want a mild everyday bit"

"My horse puts its tongue over the bit"

Choose a ported mouthpiece, which gives the tongue room.

"My horse leans on the bit or locks its jaw"

"My horse is strong and I need more brakes"

These bits are for experienced riders with soft, steady hands.

Mouthpiece materials

  • Stainless steel: strong, rust-resistant, easy to clean.
  • Copper (rollers or inlays): encourages salivation and a soft mouth. Darkens naturally over time.
  • Sweet iron: oxidizes to a sweet taste horses like. Turns from blue to brownish-grey with use, which is normal.
  • German silver: a copper-rich alloy with a warm gold tone. Contains nickel, so avoid it for horses with a nickel allergy.

Thickness

  • Slim (10 mm): best for horses with a small mouth, low palate or thick tongue. Gives clear, precise signals.
  • Medium (14 to 16 mm): comfortable for most horses.
  • Thick (18 mm): spreads pressure, but only suits horses with enough room in the mouth.

How to measure

  1. Place a piece of string in your horse's mouth where the bit sits.
  2. Mark both sides at the corners of the lips.
  3. Measure between the marks. That's your bit size.

Between sizes? Choose the larger one. For a Waterford, add 1/4" to 1/2". See our full Size Guide.
