Choosing the right horse bit can be a daunting task, especially with so many options available. There are several types of horse bits, each designed to serve a specific purpose.
A snaffle bit, for example, is a popular choice for many riders because it allows for clear communication between the horse and rider. It's a simple, gentle bit that's suitable for most riding styles.
A curb bit, on the other hand, is often used for more advanced riders who need a bit of extra control. It's a more complex bit that can be uncomfortable for some horses if not used correctly.
The type of bit you choose will depend on your horse's individual needs and your riding style.

Types of Horse Bits
If you're new to horse riding, you may not know that there are several types of horse bits to choose from. One of the main types is the snaffle bit, which comes in various styles such as D-ring, full cheek, and eggbutt.
A snaffle bit's simple design consists only of a mouthpiece and a cheek piece, with the cheek piece coming in different shapes that apply pressure to the horse's mouth in a slightly different way. The cheek piece is a crucial part of the bit, as it helps to communicate with the horse.
The D-ring snaffle bit is a popular choice for training young horses, as it helps to keep the snaffle mouthpiece in a consistent position. The full cheek snaffle bit, on the other hand, exerts lateral pressure on the sides of the mouth to encourage response to rein signals.
Here are some common types of snaffle bits:
- D-ring snaffle bit
- Full cheek snaffle bit
- Eggbutt snaffle bit
Each type of snaffle bit has its own unique characteristics, and choosing the right one for your horse can make a big difference in your riding experience.
Types of Horse Bits
Loose ring snaffle bits are a popular choice for training young and green horses, as they are flexible and not restrictive. They allow the horse to situate the bit in a comfortable position in its mouth.
A loose ring snaffle bit can cause pinching, particularly if your horse is mouthy or likes to play with its bit. To prevent this, you can use bit guards to keep the hinge of the bit away from your horse's sensitive skin.
Single jointed loose ring snaffle bits act on the tongue and lower jaw, providing a clear and independent rein aid. This allows for precise communication with your horse.
Double jointed loose ring snaffle bits have a less concentrated effect and can easily dilute the aids. They are often used by riders who want a bit that will provide a gentle and subtle pressure on the horse's mouth.
D-ring snaffle bits have D-shaped rings fixed to either side, which help keep the snaffle mouthpiece in a consistent position. This allows riders to clearly communicate with their horse around tight turns.
A D-ring snaffle bit is particularly recommended for stiff horses that don't want to bend for physical or psychological reasons. The D-shaped side pieces provide lateral containment, distributing the pressure along the mouth and encouraging the horse to yield laterally.
Here are some popular types of snaffle bits and their characteristics:
Full cheek snaffle bits exert lateral pressure on the sides of the mouth to encourage response to rein signals. They are often used with bit keepers to hold the cheek pieces in position and prevent them from getting caught on surroundings.
The right type of bit for your horse depends on its individual needs and your riding goals. Consider factors such as your horse's comfort level with the bit, its level of training, and your desired level of control.

Eggbutt
The eggbutt snaffle bit is a popular choice for its simplicity and comfort, with egg-shaped rings fixed to the bit that prevent pinching the horse's mouth. This design makes it a gentle option for many horses.
The eggbutt bit differs from a loose ring bit only in its fixed side pieces, which run slightly wider towards the outside and then merge into the bit rings. This design offers the horse more lateral guidance and limitation than a loose ring snaffle bit.
A good alternative to the eggbutt bit is the D-ring snaffle bit, which is suitable for horses with small/narrow mouths that may not respond well to the thickness of the eggbutt bit. Some strong horses may not respond to the eggbutt bit, so it's essential to choose the right bit for your horse.
The eggbutt bit is available in both single and double jointed variations, and its fixed rings allow for a more direct effect on the lower jaw and tongue. This makes the signals reach the horse faster and more clearly.

Here are some examples of eggbutt bits available in the market:
- Qualcraft Eggbutt Mullen Mouth Bit £44.90
- GOLD MEDAL Mullen Mouth Bit £34.90
- APPLE MOUTH 5.02 Eggbutt Mullen Mouth Bit £34.90
- SILK STEEL Mullen Mouth Bit £24.90
It's essential to consider the ring design when choosing a snaffle bit, and the eggbutt bit is one of the most popular styles available. O-ring and egg butt bits are probably the most popular styles, but it's crucial to choose the right bit for your horse's specific needs.
Gag
Gag bits are designed for horses that lean on or pull strongly on the bit, creating upward pressure on the lips and poll to encourage the horse to raise its head and become more responsive.
They're typically used in show jumping, eventing, and polo, but should not be used in hunter or dressage events where the horse is expected to appear relaxed. Gag bits should be handled by experienced riders, as the leverage can be quite strong.
Gag bits act only on the mouth and poll, without a curb strap to signal the horse to turn their head inwards. This means horses respond only by lowering their head rather than tucking their chin.
Suggestion: Horse Bits
The most common types of gag bits include the conventional, draw or running gag, wonder gag, elevators, and Dutch gag. Each of these types has a unique mechanism for creating leverage and pressure on the horse's mouth.
Here are some key features of each type of gag bit:
- Conventional, draw or running gag: This bit has a rope that runs from the bridle and attaches to the reins, giving a "draw action" when the rider pulls on the reins.
- Wonder gag: This bit looks like a loose ring snaffle with a purchase and shanks, and activates the lips and the horse's poll when the rider pulls on the reins.
- Elevators: These bits are similar to a Pelham, but have a long purchase and usually longer shanks, creating a "pseudo-gag" action.
- Dutch gag: Also called a four-ring or bubble bit, this type of bit looks like a loose ring snaffle with additional rings welded to the top and bottom of the loose ring.
Elevator bits may have one or two rings on the shanks, allowing riders to control the strength of the gag action.
Weymouth
The Weymouth bit is a sophisticated piece of equipment. It consists of a continuous piece of metal with one upper and one lower shank.
A bradoon is required for the use of a Weymouth bit, which can make it a bit more complicated to set up. This is because the bradoon acts on the tongue and the lower jaw, allowing for finer and more differentiated aids.
The Weymouth bit is used with two pairs of reins and a curb chain, which should be buckled in such a way that it responds at an angle of 45° between the Weymouth shank and the cleft of the mouth. This helps to limit the leverage effect and avoid surprising the horse.
For bits with curved shanks, you can use the halfway point of the shanks as a guide. This can make it easier to set up the bit and ensure that it's working correctly.
Mullen Mouth Selection
Choosing a mullen mouth bit can be a bit overwhelming, but understanding the basics can make all the difference. A mullen mouth bit lies evenly on the tongue and distributes the pressure steadily over the entire width of the tongue, even on a loose rein.
The correct choice of bit width is particularly important with a mullen mouth bit, as a bit that is too large will press hard on the edges of the tongue and the lower jaw. It's essential to get it right to ensure your horse's comfort.
A mullen mouth bit is more suitable for horses that are well trained and can be flexed and bended with fine aids without a lot of effort. This is because the bit tilts and twists when only one rein is shortened, which can be uncomfortable for the horse.
If you're looking for a bit that targets three different points of action, consider a kimblewick bit. The kimblewick is very suitable for training as a precursor to the weymouth bit.

Remember, choosing the right bit for your horse is a trial-and-error process, and you may need to try several before finding one that works for you and your horse.
Materials
Stainless steel is a popular choice for making bits because it doesn't rust, making it a great option for everyday use.
Copper is often used in bit making because it causes the horse to salivate, which can make the bit slide or rotate more easily in the horse's mouth.
Sweet iron is a type of metal that is very palatable to horses, making it a popular choice among experienced horsemen. This metal rusts easily, but it's worth it for the benefits it provides.
Aluminum is not a desirable metal for bit construction due to its light weight and unpalatable taste. It can also oxidize readily, causing the bit to break unexpectedly.
The amount of copper on a bit can range from small inlays that rest against the horse's tongue to fairly large rollers. This variation can be helpful in finding the right bit for a particular horse.

Some horses prefer the taste of certain metals over others, while some horses cannot tolerate metal bits whatsoever. A degree of experimentation may be necessary to determine what bit material works best for a horse.
Here are some common mouthpiece materials used in bit making:
- Stainless steel: The conventional material for making bits
- Copper: Promotes increased salivation in horses
- Sweet iron: A sweet-tasting metal that promotes increased salivation in horses
- German silver: A gold-colored metal that tastes sweeter than regular stainless steel
- Rubber or plastic: Provides a softer feel for the horse's mouth
- Leather: Provides a soft feel and conforms to the shape of the horse's mouth when wet
Bit Design and Components
When choosing a mouthpiece, consider the mullen, or arc, which can impact the severity of the bit's action. A mullen can be either an arc or a shape, and its design plays a crucial role in the bitting process.
Riders may opt for straight bars without a mullen to increase the severity of the bit's action. This type of bit typically has a stronger action on the horse's tongue.
The style of the bit's bars also varies, with some bits having a stronger action on the horse's tongue before it contacts the horse's jaw. Some horses resist this additional tongue pressure and cannot tolerate bits without a mullen.

Pelham
The Pelham bit combines elements of both a snaffle and curb bit, featuring shanks that create leverage and apply pressure on the poll and curb for added control.
This type of bit is often used in the equitation ring and fox hunting due to its strength.
Intermediate riders may find it easier to use one rein with bit connectors to join the snaffle with the curb when using a Pelham bit.
The Pelham bit is not permitted in dressage, so it's essential to check the rules of your specific riding discipline.
Kimberwick
The Kimberwick bit is a type of curb bit that's designed to prompt the horse to lower its head. It has a D-ring design and a mild leverage effect.
The classic Kimberwick and the Uxeter Kimberwick are two styles of Kimberwick bits. The Uxeter Kimberwick features slots for the reins, offering more leverage.
Kimberwick bits come in various mouthpieces, including jointed, unjointed, low port, and roller mouth.
Bit Design and Components

A mullen mouth bit is a type of bit that consists of a fixed mouthpiece without a movable joint. The side pieces can be fixed or continuous rings. With a mullen mouth bit, the correct choice of bit width is particularly important, as otherwise a bit that is too large will press hard on the edges of the tongue and the lower jaw.
The mullen mouth bit lies evenly on the tongue and distributes the pressure steadily over the entire width of the tongue, even on a loose rein. This is because the bit doesn't tilt or twist when the reins are shortened, unlike some other types of bits.
A mullen mouth bit is more suitable for horses that are well trained and can be flexed and bended with fine aids without a lot of effort. This is because the bit can only flex and bend to a limited extent.

There are different types of mullen mouth bits available, including the kimblewick bit. The kimblewick bit targets three different points of action: the tooth-free interspace of the jaw and tongue, the lower jaw and chin, and the neck.
Here are some examples of mullen mouth bits available in the market:
The baucher bit is another type of bit that is often used in baroque and Spanish riding. It is available as a single or double jointed bit or as a mullen mouth bit. The cheek piece is attached to the small upper shank, while the reins are buckled into the bit rings.
Sizing
Sizing is a crucial aspect of bit design, and it's essential to get it right to ensure a comfortable and effective ride for both you and your horse. The width of the bit is the distance between the two cheek pieces, and standard bits are 5 inches wide.

Most standard bits are 5 inches wide, but there are specialized bits for smaller or larger horses. Pony bits are generally 4 1/2 inches wide, and bits designed for Arabians and other light-boned horses are 4 3/4 inches wide.
For horses with wider mouths, bits are available in widths of 5 1/2 inches, 6 inches, and even wider for some draft horses. Bits wider than 5 inches may have to be special ordered, and the availability of styles and mouthpiece designs may be limited.
To determine the right bit size for your horse, consider their conformation, including the width of their mouth, the size of their tongue, and the available space between their tongue and palate.
A good rule of thumb is to have an experienced person examine the bit's fit in the horse's mouth to ensure it doesn't pinch the tongue, and that the bit doesn't interact with the horse's palate unintentionally.
Here are some key factors to consider when evaluating the fit of a bit:
- Pinching of the tongue
- Thickness of the bit relative to the horse's mouth
- Interaction with the horse's palate
The thickness of the mouthpiece also impacts the severity of the pressure applied to the horse's mouth. Thinner mouthpieces produce sharper pressure, while wider mouthpieces produce a duller pressure.
Mouthpiece Design
Mouthpiece Design is a crucial aspect of bitting, as it can greatly impact the severity of the bit's action. The design of the mouthpiece can vary based on the mouthpiece configuration, mullen, and the style of the bit's bars.
A straight bar, without a mullen, typically has a stronger action on the horse's tongue, as activating the bit first puts pressure on the tongue before it contacts the jaw. Some horses resist this additional tongue pressure and cannot tolerate bits without a mullen.
The type of mullen, or arc, can also affect the mouthpiece design. For example, some bits have a mullen that is shaped like an egg, while others have a wavy mullen.
Here are some examples of mullen mouth bits available in the market:
- QualcraftEggbutt Mullen Mouth Bit
- SHOWMASTERRubber Snaffle Bit, Thickness 18mm
- GOLD MEDALMullen Mouth Bit
- APPLE MOUTH5.02Eggbutt Mullen Mouth Bit
- SILK STEELMullen Mouth Bit
- APPLE MOUTH5.01Mullen Mouth Bit, wavy
D-Ring and Full Cheek Selection
A D-ring snaffle bit is particularly recommended for stiff horses that do not want to bend for physical or psychological reasons.
The D-shaped side pieces of a D-ring snaffle bit provide lateral containment, distributing pressure along the mouth and pushing the horse in the direction of the rein.
Full cheek snaffle bits have a similar effect, but with even more lateral restraint due to their long shanks.
A D-ring snaffle bit is well suited for horses with little space in the mouth, as the mouthpiece remains narrow.
Here are some options for D-ring and full cheek snaffle bits:
Bit Selection and Choosing
Choosing the right type of bit for your horse is a trial-and-error process. You may need to try several before finding one that works for you and your horse.
To start, consider your horse's needs and goals. If you want to increase control, supplement training, or improve comfort, choose a bit that suits your horse's temperament and experience level. Snaffle and breaking bits are best for beginner riders and young or inexperienced horses, while curb bits are best for horses that are experienced or respond to stronger pressure.
Here are some factors to consider when selecting a bit:
- Mouth size: A bit that's too small will pinch your horse's mouth, while a bit that's too big will slide around and make communication difficult.
- Conformation: Horses have different tongue thicknesses, jaw alignments, and head carriage, which determine whether they need a thicker or thinner bit.
- Injuries: If your horse has a sensitive or injured mouth, choose a gentler bit.
- Experience level: Snaffle and breaking bits are best for beginner riders and young or inexperienced horses, while curb bits are best for horses that are experienced or respond to stronger pressure.
- Discipline: Different disciplines have specific requirements for the types of bits used.
- Preference: Observe what kind of pressure your horse best responds to, whether that be on the poll, tongue, mouth, or curb.
A good bit is also characterized by the fact that its surface is intact, and the material is suitable for your horse's needs. Consider the size, make, and material of the bit to ensure it's comfortable for your horse and provides effective communication.
Choosing the Right Equipment for Your Horse
Choosing the right equipment for your horse is crucial for effective communication and a comfortable ride. A good bit is essential for this, and it's not just about picking any bit off the shelf. You need to consider your horse's individual needs and preferences.
Know your horse inside out before shopping for a bit. Spend time working with them and learn how to communicate effectively. This will help you choose the right type of bit and mouthpiece style for your horse.
If your horse is already comfortable with a particular type of bit, stick with it unless there's a reason to change. Consider your goals for using the bit - do you want to increase control, supplement training, or improve comfort? This will help you choose the right bit for your horse.
A gentle bit is a good starting point, especially if your horse isn't used to a bit or you're switching styles. Gradually introduce a stronger bit if needed, and don't be afraid to try before you buy.

Bit Comparison and Types
There are several types of horse bits, each with its own unique characteristics. The most common types of horse bits are snaffle bits, curb bits, and pelham bits.
A snaffle bit, as we learned in the article, is a type of bit that applies gentle pressure to the horse's mouth and bars. It's a great choice for young or inexperienced horses.
Snaffle bits come in different sizes, with the most common being 5, 5.5, and 6 inches. These sizes are designed to fit different horse breeds and head sizes.
Curb bits, on the other hand, are designed for more advanced horses and apply more pressure to the horse's mouth and poll. They're often used for horses that are strong-willed or hard to train.
Curb vs
Curb bits use leverage to multiply the amount of pressure applied, distributing it to the horse's poll, chin, and mouth. This is in contrast to snaffle bits, which work with direct pressure.
The reins attach directly to the bit's mouthpiece in a snaffle bit. This means the rider feels exactly what the horse feels.
A curb bit's leverage effect can be intense, so it's recommended for experienced riders only. This is to avoid causing discomfort to the horse.
The longer the shank on a curb bit, the greater the leverage effect.
Single Jointed vs Double Jointed Bits
Choosing between a single jointed and a double jointed bit can be a bit overwhelming, especially for new horse riders. The original belief was that a double jointed bit is preferable to a single jointed bit.
However, a single jointed bit can lead to the "nutcracker effect" when pulled, causing discomfort to the horse. The single joint can rise up like a roof and dig into the palate, while the sides press into the lower jaws.
The horse can escape this pressure by lifting the bit upwards with the tongue, thus pushing it away from its jaws. This is a clever trick, and it shows that horses are intelligent and capable of adapting to their environment.
A double jointed bit, on the other hand, encloses the tongue and makes it impossible for the horse to escape the pressure by lifting the tongue. This can lead to bruising in the worst case.

Bit Safety and Considerations
Choosing the right bit for your horse is crucial for their comfort and safety. The most comfortable bit for your horse is one that fits properly, taking into account their mouth size and conformation.
A bit with a port that provides room for the tongue can be a good option for horses with mouth pain or sensitivity. This reduces pressure in the tongue area and can make riding more comfortable for them.
If your horse refuses bits, has a mouth injury, or experiences mouth sensitivity, a hackamore may be the way to go. Hackamores are a type of bitless bridle that apply pressure to the nose, chin, and poll using leverage.
Bits become uncomfortable when too much pressure is applied, or when pressure is applied in the wrong areas. This can be due to the rider's inexperience or improper training.
A larger diameter mouthpiece results in the pressure applied to the tongue and bars being diffused over a larger surface area, making these bits less severe. This is a good option for most people and horses.
Harsher bits should be reserved for people who know how and when to use them and have the patience and dexterity to use them properly. This is because harsh bits can be problematic and should not be used as a substitute for proper training.
The degree of pressure a bit applies depends on its action and configuration. For example, snaffle bits have a 1:1 ratio of pressure, while leverage bits have a leverage effect that increases pressure coming from the rider's hand.
The mouthpiece of the bit also affects its severity, with some mouthpieces having a "sharper" effect on the horse's mouth. This can make the bit more severe, regardless of its action or configuration.
Relying on a stronger bit to fix problems encountered during training is not a good idea. All riders should aim to ride in the gentlest bit possible for their horse, to maximize their welfare.
