Choosing the right bit is essential for your horse's comfort and the quality of communication between horse and rider. However, with so many different mouthpieces available, it can often be difficult to know which bit is truly suitable for your horse.
Contrary to popular belief, there is no universal “best bit”. The right bit is the one that suits each horse's conformation, sensitivity, level of training and specific needs.
Discover in this guide how to choose the right bit for your horse.
Why is choosing the right bit so important?
The bit acts directly inside the horse's mouth, a particularly sensitive area that includes the tongue, bars, corners of the lips and, in some cases, the palate.
An unsuitable bit can cause:
- resistance to the rider's hand;
- difficulty steering;
- contact issues;
- head shaking;
- an open mouth;
- tension in the neck;
- a loss of confidence.
Conversely, a well-suited bit encourages finer communication that is more comfortable and respectful of the horse.
What criteria should you consider when choosing a bit?
1. Your horse's sensitivity
Every horse has its own level of sensitivity.
Sensitive horses generally appreciate:
- double-jointed bits;
- anatomical bits;
- resin bits;
- bits with an ergonomic mouthpiece.
Conversely, some horses that are heavier in the hand or more powerful may need a bit that provides greater guidance or precision.
The aim should never be to look for greater severity, but rather better understanding.
2. The conformation of the mouth
Not all horses have the same mouth conformation.
In particular, you should consider:
- the thickness of the tongue;
- the width of the bars;
- the height of the palate;
- the size of the mouth.
A horse with limited space in its mouth will often prefer a thinner or anatomically shaped mouthpiece.
A horse with a thick tongue may be more comfortable with a bit that provides more room for the tongue.
3. Age and level of training
Young horse
For a young horse, riders generally favour:
- simple bits;
- mild bits;
- comfortable mouthpieces;
- mouthpieces that encourage the horse to learn to accept the contact.
Full-cheek bits and certain double-jointed bits are particularly popular when starting young horses.
Experienced horse
As their training progresses, some horses may move on to more technical mouthpieces designed to meet specific requirements relating to their discipline or level of training.
4. Your equestrian discipline
The choice of bit also depends on the discipline.
Dressage
Riders often look for:
- stability;
- precision;
- refined contact.
Baucher bits, eggbutt bits and double-jointed bits are particularly popular.
Show jumping
Requirements vary more widely depending on the horse's temperament and the level of control required.
Common choices include:
- Pessoa bits;
- D-ring bits;
- eggbutt bits;
- gag bits.
Hacking and trail riding
Comfort and relaxation are generally the main priorities.
Anatomical or resin bits are particularly popular for this type of riding.
The main types of horse bits
The single-jointed bit
The single-jointed bit is one of the most widely used types of mouthpiece.
Advantages:
- simple;
- versatile;
- suitable for many horses.
Things to consider:
- it may create more concentrated pressure in some sensitive mouths.
The double-jointed bit
The double-jointed bit distributes pressure more evenly.
Advantages:
- greater comfort;
- more stable contact;
- particularly popular for sensitive horses.
The eggbutt bit
Thanks to its fixed rings, it provides greater stability in the horse's mouth.
It is often recommended for:
- young horses;
- sensitive horses;
- riders looking for consistent contact.
The D-ring bit
The D-ring bit provides greater lateral guidance while remaining relatively mild.
It is particularly popular for:
- young horses;
- flatwork;
- horses that need additional guidance.
The Pessoa bit
The Pessoa bit works through a leverage action.
It is mainly used:
- in show jumping;
- for certain strong horses or horses that tend to take control.
Its use should always be carefully considered and suited to the experience and level of both horse and rider.
What size bit should you choose?
The size of the bit must correspond precisely to the width of the horse's mouth.
A bit that is too small may pinch the corners of the lips.
A bit that is too large can become unstable and less precise.
To measure correctly:
- use a bit measure or a piece of string;
- measure the internal width of the mouth;
- add a few millimetres depending on the type of bit rings.
The most common sizes are:
- 115 mm;
- 125 mm;
- 135 mm;
- 145 mm.
Mistakes to avoid
Choosing a stronger bit to solve a training issue
Most difficulties are more often related to:
- training;
- balance;
- the rider;
- discomfort.
Changing the bit is rarely the only solution.
Copying another horse's tack
Every horse has a different mouth.
What works perfectly for one horse may be uncomfortable for another.
Neglecting the condition of the horse's mouth
Regular dental checks are essential before making any changes to your horse's bit.
How can you tell if a bit suits your horse?
A horse that is comfortable with its bit will generally show:
- gentle chewing;
- stable contact;
- a relaxed mouth;
- a consistent way of going;
- greater responsiveness during work.
Conversely, certain signs should alert you:
- an open mouth;
- head shaking;
- the tongue going over the bit;
- repeated resistance;
- difficulty accepting the contact.
Conclusion
Choosing a bit is not about looking for greater control, but about finding the best balance between comfort, communication and precision.
Your horse's sensitivity, conformation, level of training and equestrian discipline should always guide your choice.
If in doubt, opt for a simple, comfortable mouthpiece that suits your horse's mouth. A well-chosen bit contributes directly to your horse's well-being and to the quality of your relationship every day.
