Why Saddle Fit Is So Important

A poorly fitting saddle is one of the most common — and most overlooked — causes of problems in horses. Back pain, behavioural issues, reluctance to go forward, bucking, and resistance in transitions can all be traced back to an ill-fitting saddle. For the rider, the wrong saddle makes it impossible to sit in a correct, balanced position, which creates tension, interferes with the aids, and increases the risk of falls.

Choosing a saddle is therefore one of the most important decisions you'll make as a horse owner or rider. It's not a purchase to rush or skimp on.

Types of Saddle

The first step is choosing the right type of saddle for your riding discipline:

  • General Purpose (GP) – a versatile design suitable for flatwork, hacking, and small jumps. The best starting point for most amateur riders.
  • Dressage saddle – longer, straighter flap that positions the leg further back and down. Deep seat encourages stillness and connection.
  • Jump saddle – forward-cut flap to support the shorter stirrup length used in jumping. Usually has knee rolls for stability.
  • Close-contact saddle – minimal padding between rider and horse, preferred by show jumpers who want maximum feel.
  • Western saddle – a heavier, horn-equipped saddle for Western riding, trail riding, and ranch work.
  • Endurance saddle – designed for long-distance comfort, with weight distribution over a large area and often multiple D-rings for equipment.

Fitting the Saddle to Your Horse

A saddle must fit your horse correctly — this is non-negotiable. The key points to check are:

Gullet Width

The gullet (the channel running along the underside of the saddle) must clear the horse's spine from pommel to cantle, with no part of the saddle pressing on the spine. You should be able to fit three fingers' width between the pommel and the withers when the rider is mounted.

Panel Contact

The panels (the padded underside of the saddle) should make even, full contact along the horse's back without bridging (touching only at the front and back), rocking, or pinching. Any uneven pressure will cause soreness over time.

Length

The saddle must not extend past the last rib. Any saddle that sits over the loins places pressure on an unsupported area and will cause significant discomfort and muscle damage over time.

Balance

When placed on the horse's back without a rider, the saddle should sit level. If the front is too high or the back tips down, the rider will be pushed into an incorrect position.

Fitting the Saddle to the Rider

A saddle that fits the horse perfectly still needs to fit you. Key considerations:

  • Seat size – measured in inches (e.g., 16.5", 17", 17.5", 18"). You should have a hand's width between your seat bone and the back of the cantle. If you're crammed in or sliding around, the size is wrong.
  • Flap length – should suit your leg length and proportions. Riders with long legs often need a longer or more forward-cut flap.
  • Tree width relative to your pelvis – a tree that is too wide or too narrow will push your seat bones into an uncomfortable position.

New vs. Second-Hand Saddles

New Saddle Second-Hand Saddle
Cost Higher initial investment More affordable
Fit customisation Can often be built or adjusted to spec Limited unless flocked
Condition New, clean, no wear Varies — always inspect carefully
Break-in period Leather needs breaking in Usually already supple
Risk Low Higher — check tree integrity

Always Use a Qualified Saddle Fitter

No online guide — including this one — can replace a hands-on assessment by a qualified master saddler or certified saddle fitter. If you are spending a significant amount on a saddle, always have it fitted professionally. Most reputable fitters will assess both horse and rider, and many offer a trial period so you can feel the difference in the saddle before committing.

As your horse's topline develops (or as they age), saddle fit should be reviewed at least once a year, or any time you notice a change in your horse's movement, attitude, or condition.
