Guide to Reins for Horses: Types, Functions & Positions as a Riding Aid

Reins are an essential part of equestrian activities, acting as a direct line of communication between rider and horse. Attached to the horse’s bridle or bit, reins allow for clear communication through subtle movements of the rider’s hands, influencing the horse’s direction, speed, posture, and overall responsiveness.

Using reins correctly is key to ensuring a positive and effective equine partnership. “Heavy-handedness,” or pulling harshly on the reins, can lead to discomfort and confusion, negatively affecting the horse’s willingness to respond.

Gentle, consistent rein cues enable the rider to provide clear signals asking for a variety of movements, including turning, slowing down, and head position. It’s also important to select an appropriate type of reins for your discipline and horse’s level of ability.

Read on to learn more about the types of reins, different reining positions, and how reins are used as riding aids to help you make an informed decision about what type of reins to use for your horse.

Reins & Horsemanship

Reins are straps or ropes attached to a horse’s bit or bridle that a rider uses to communicate with the horse.

They serve as a direct line of contact between the rider’s hands and the horse’s head, allowing for cues related to:

• Direction
• Speed
• Responsiveness
• Posture
• Head position

The way a rider handles the reins determines what the horse feels in and around its mouth. By keeping rein cues clear and consistent, the horse can learn what movements the rider is asking them to perform.

The tension, position, and movement of the reins allow the rider to communicate their intentions to the horse. This includes cues for: ^[1]

• Turning left or right
• Slowing down or stopping
• Adopting specific postures
• Shifting weight distribution
• Adjusting head position and movement

Since the rider controls how the reins act on the horse’s mouth and bridle, it’s important for riders to have ‘soft hands’ – to apply controlled, gentle rein pressure on the bridle and bit when asking the horse to perform.

Riders who are too rough, lack patience, or do not pay attention to their actions in saddle run the risk of hurting the horse. This can lead to serious behavior problems and unwillingness to work, a state some owners describe as “ruining” the horse. ^[1]

Types of Reins

Different riding disciplines require specific types of reins, each designed to suit the demands of the sport and enhance the rider’s ability to guide the horse effectively. English and Western riding use distinct rein styles, with variations in material, structure, and functionality. ^[1] Additionally, specialized training reins, such as draw reins, provide additional tools for refining a horse’s movement and responsiveness.

Understanding the differences between these rein types is essential for selecting the right equipment for any riding discipline.

English Reins

English reins are designed to provide precise communication between the rider and the horse, allowing for subtle cues and controlled movements.

These reins attach to the bit on both sides and connect in the middle, creating a continuous loop. They come in various styles, each offering different levels of grip, flexibility, and comfort.

Reins used for English riding include: ^[1]

• Plain Reins: Straps made of flat leather. They are comfortable to hold, but can become slippery when wet.
• Laced Reins: Made from thin strips of leather laced through or around the strap of the rein to increase security of the grip.
• Web Reins: Come with loops set into the leather at intervals or with rubber constructed into the grip to increase security of the grip, particularly in wet conditions. Cotton web and leather are incorporated into the bit and buckle ends.
• Rubber Reins: Similar to plain reins, these are textured to increase security of the grip.

Western Reins

Western reins are built for versatility and control, catering to the needs of riders in disciplines such as reining, cutting, and barrel racing.

Unlike English reins, some Western reins do not buckle together or otherwise connect in the middle. Each type serves a specific purpose, from allowing precise neck reining to providing a secure grip for roping and working cattle. Western rein styles include: ^[1][2][3]

• Split Reins: The most common reins found in Western riding overall. They consist of two straps, each attached on either side of the bit and left open at the rider’s end. They can be long or short.
• Romal or California Reins: Unlike a split rein, the Romal rein is a single strap typically made of braided rawhide attached at either end to the bit. These reins are equipped with a quirt, which is a short riding whip with a handle and one or two lashes.
• Roping or Single Reins: Like the Romal rein, this is a single strap attached to the bit on either end, with the addition of snaps on one or both sides that make it possible to change out sets of reins quickly.
• Mecate Reins: These reins incorporate a lead and reins into one unit, with part looped from one side of the bit to the other and the rest left loose. They are typically made of horsehair or rope.

Draw & Side Reins

Other types of reins are primarily used for training purposes and include: ^[4][5]

• Draw Reins: These reins run from the rider’s hands, through the bit rings, and attach near the girth (either between the front legs or at the sides). Draw reins are used while the horse is mounted and are designed to encourage the horse to lower its head and flex at the poll, often with the goal of promoting a rounder frame and improved head carriage.
• Side Reins: These reins attach from the bit to the saddle or surcingle and are typically used while the horse is being lunged. They help promote balance and a consistent outline by encouraging the horse to maintain steady contact and proper alignment without a rider.

Both draw and side reins are the subject of ongoing debate in the equestrian world. While they can be effective when used correctly by experienced handlers, some argue that they can be misused — set too tight or employed without proper understanding — leading to forced head positions, tension, and physical discomfort for the horse. ^[4][5]

Overuse or incorrect adjustment can cause horses to move in a false frame, disengage their hindquarters, or develop resistance. For these reasons, their use should be approached with caution and always prioritized as part of a broader training strategy that emphasizes softness, engagement, and rider education. ^[4][5]

Rein Positions & Handling

Equestrians use different hand and rein positions to cue their horses. Variations in these techniques depend on the level of skill the rider has, the style of riding, and the specific discipline.

Two-Handed Position

Holding the reins in both hands is standard in English riding. The reins rest in the palms, secured by the thumb and index finger, with hands slightly inclined (about 30 degrees) and thumbs facing upward. Reins can be placed under the little finger or between the little and ring fingers. Loose ends drape over the right side of the horse’s neck or are crossed for safety. ^[1]

To adjust length, each hand grasps the opposite rein to maintain light contact with the horse’s mouth. ^[1]

Bridge Position

Used with split reins, this position involves crossing the reins over the horse’s neck, so the loose ends hang on either side. The rider holds the reins as a single unit, positioning them under the little finger or threading them toward the thumbs. ^[1][2]

One-handed reining is common in Western disciplines. To adjust the length, one hand slides along the reins while the other remains steady. ^[1]

Three-Rein Position

This position is similar to the bridge position, but one hand holds its rein independently while the other holds both its rein and the bight of the opposite rein. The active rein is shortened as needed and switches sides when necessary. ^[1]

This position helps transition horses from two-handed to one-handed riding. Advanced Western riders typically move on to using a leverage bit held with one hand, with the rein ends hanging on the same side. ^[1]

Split & Romal Reins

Split reins can be held with no fingers between them, but the preferred method is to place the index finger between the reins and keep the palm facing downward. ^[1] This is sometimes called the pistol grip. ^[2]

When using romal reins, the rider holds the reins together in their non-dominant hand with no fingers in between the reins, which is a disqualifying penalty in most disciplines where romals are required. The reins run up through the bottom of the hand and exit through the top, while the quirt is held in the rider’s dominant hand at least 40 cm (15.75 inches) from the rein hand. ^[1]

Four Reins

In English riding, experienced riders may use a leverage bit, such as a pelham or double bridle, with two hands on four reins. In most cases, the snaffle rein sits outside and passes under the little finger, while the curb rein is inside, positioned between the little and ring fingers. This allows for subtle snaffle cues before engaging the curb rein. ^[1] However, there are numerous ways to hold four reins depending on the discipline and the rider’s goals when activating the bit in the horse’s mouth.

Double bridles are particularly common in advanced dressage classes.

Rein Aids

To communicate effectively with their horse, a rider must be consistent and gentle, using movements known as aids that the horse can recognize and understand. Poor rein use can damage a horse’s responsiveness, while proper technique refines movement and direction.

In general, the actions the rider uses on the reins can communicate several intentions to the horse. These include: ^[6]

• Yielding: Giving or releasing pressure
• Asking: Requesting or prompting action
• Non-yielding: Maintaining steady or firm pressure
• Regulating or ‘Guarding’: Controlling or managing movement
• Sideways-acting or ‘Opening’ Rein: Rein tension that encourages lateral movement or turns

Although there are numerous detailed choices the rider can make about how to communicate directions to their horse, the following are the most common and consistently used reining aids:

• Open
• Direct
• Indirect
• Rein of Opposition

Open Rein

The open rein is often used with young horses. The rider moves their rein hand away from the neck on the side they want the horse to turn towards. This rein encourages the horse rather than forcing it. ^[1]

Open rein is also applied strongly during emergency stops until the horse regains control. This aid must be used cautiously to avoid excessive bending that could cause loss of balance. Chin straps or cavessons are used to prevent the bit from slipping through the horse’s mouth during open reining. ^[1]

Direct Rein

A more refined rein, the direct rein involves applying bit pressure by pulling the rein toward the rider’s hip, keeping a straight line from elbow to bit. This technique helps with turns, collection, and slowing the horse. ^[1]

Direct reining is used more frequently as the horse advances in training. Two-handed use creates flexion, while a single hand helps with turning. ^[1]

Indirect Rein

This rein applies light pressure to the side of the horse’s neck, encouraging movement away from the rein without pulling. The rider should keep their hand inside their shoulder during indirect reining to avoid putting excess pressure on the mouth. ^[1]

The indirect rein is paired with a direct rein during initial training. As the horse gains skills, the rider can transition to indirect neck reining, where the pressure is on the neck and not the mouth. ^[1]

Rein of Opposition

Used to correct the horse’s shoulders or prevent drifting in turns, the rein of opposition involves moving the rein toward the opposite shoulder while the support rein maintains balance. ^[1]

Leg aids assist in lateral movement, and the rider’s seat helps control the horse’s direction while executing a rein of opposition. As the horse and rider develop, this technique becomes more advanced, improving the rider’s ability to adjust the horse’s posture and movement. ^[1]
