When it comes to horse riding, choosing the right bit is paramount for maintaining effective communication with your horse. Bits, the metal mouthpieces attached to the bridle and reins, range from mild to severe in terms of harshness.

A bit's severity depends on its design and the pressure it applies to the horse's mouth, and it should correspond with your horse's level of training and temperament.

Understanding Horse Bits

Horse bits serve as a crucial channel of communication between the horse and the rider. The metal mouthpiece, when paired with the reins, allows the rider to signal the horse to turn, stop, or quicken its pace.

The gentler bits, such as the snaffle, feature a simple design and distribute pressure evenly across the horse's mouth. For more advanced riding requiring a skilled hand, a curb bit, which applies pressure to the horse's mouth, chin, and poll, is more suitable. A gag bit, the most severe of the lot, is intended for use on horses that are challenging to control. However, this bit should only be in the hands of experienced riders who can use it properly.

Unpacking Bit Types

Ranging from the simple snaffle bit to the more complex twisted bit, horse bits come in a myriad of designs each intended to apply varying degrees of pressure to the horse's mouth.


Snaffle Bit

The snaffle bit is the most basic, and its simplicity makes it the mildest type. It is commonly used in training young horses and for regular riding. Its design helps apply gentle pressure to the horse's mouth, making it ideal for sensitive horses.

Curb Bit

A step up in terms of severity, the curb bit features a mouthpiece, shanks, and a curb chain. When the reins are pulled, pressure is applied to the horse's mouth, chin, and jaw. This bit is suitable for advanced riding disciplines such as dressage and show jumping.


Twisted Bit

The most severe type of bit is the twisted bit. Its twisted mouthpiece can cause significant discomfort to the horse, and therefore, it is recommended for use only by experienced riders who fully understand its function.

A Closer Look at Mild Bits

Mild bits, as their name suggests, apply minimal pressure to the horse's mouth. They are ideal for horses that are sensitive or have a low pain threshold, making them a go-to choice for training young horses or those prone to leaning on the bit.

Mild bits come in several forms, including the Eggbutt, D-ring, and Full cheek snaffle.

When selecting a bit, it's crucial to consider your horse's training level and your riding experience. Regardless of its type, a bit should always be used with sensitivity and respect for the horse's comfort. Remember, a harsh bit doesn't equate to better control, but the right bit ensures a harmonious and successful ride.

Moderate Bits

Taking a step up from the mild bits, we encounter a variety of bit types that exert a moderate amount of pressure. These are often used on horses that require a tad more control than what a snaffle can offer.

Kimberwick Bit

The Kimberwick is a popular moderate bit, known for its adjustability and mild severity. This bit is excellent for horses needing more control than a snaffle, but less harshness than a curb or a gag bit.

Pelham Bit

Providing more control than a snaffle yet not as severe as a curb bit, the Pelham bit includes two sets of reins for more nuanced communication. It is often a transitional bit for horses maturing past a snaffle but not ready for a curb bit.


Waterford Bit

Designed with interconnected links for a comfortable fit, the Waterford bit is another mild-to-moderate option, particularly for sensitive horses or those with a low pain threshold.


Full cheek snaffle

This bit provides increased control and stability, especially for turning or bending movements, yet it maintains the snaffle's overall mildness.

Harsh Bits

As we move further along the spectrum, we reach harsher bits designed for more experienced riders and horses. These bits apply a significant amount of pressure on the horse's mouth and require a skillful hand to prevent causing discomfort.


Tom Thumb Bit

Tom Thumb bits introduce a slight leverage action, applying pressure to the horse's poll and mouth, a feature that can prove useful for advanced riding and training.


Gag Bit

The Gag bit is considered severe due to its simultaneous pressure application to the horse's mouth and poll. Primarily used in training and competitions, Gag bits should only be used by riders familiar with their operation.


Twisted wire bit

As one of the harshest types of bits available, twisted wire bits should only be used by highly experienced riders. These bits create pressure points in the horse's mouth and offer considerable control.


Dr. Bristol bit: This bit employs a flat, angled plate that applies pressure on the horse's tongue. Although designed for comfort, it's still a harsher bit, landing somewhere in the middle of the harshness hierarchy.

Final Thoughts

Horse bits range from mild to harsh based on their design and the pressure they exert on a horse's mouth. It's crucial to assess your horse's comfort and your experience level when choosing a bit. No matter the bit, it should be used with respect to the horse's comfort and well-being.
