Understanding Saddle Seat Sizes

Choosing the right saddle size is an important step towards creating comfort, confidence and harmony between horse and rider.

While saddle measurements provide a useful starting point, finding the right saddle is about much more than a number. The ideal saddle should support your position, help you feel balanced and secure, and allow your horse to move freely and comfortably.

This guide explains how saddle sizes are measured, why sizing can vary between saddle styles, and how to approach finding the right fit for both you and your horse.

A quick guide to saddle seat sizes

Arena saddles are available in a range of seat sizes:

Centimeters   Inches   Range
36 cm 14" Arena Children's saddles
38 cm  15" Arena Pony saddles
40 cm 16" Arena Pony saddles
42 cm 16.5" Standard Arena saddles
43 cm 17" Standard Arena saddles
44 cm 17.5" Standard Arena saddles
46 cm 18" Standard Arena saddles

 

Seat size is measured from the center of the saddle nail to the center of the cantle. While this measurement helps identify the size of a saddle, it should be viewed as a guide rather than a guarantee of fit.

Our range includes Children's and Pony models alongside the wider range, offering smaller seat sizes designed specifically within those collections. As with all saddles, the most suitable seat size will depend on the individual rider, the saddle design, and how the saddle supports balance, comfort and confidence in the saddle.

We encourage riders to sit in a range of saddle sizes and work with a qualified saddle fitter or knowledgeable stockist, who can assess both horse and rider together and help guide the fitting process.

How do I measure a saddle's seat size?

To measure a saddle seat, place a tape measure from the center of the saddle nail to the center of the cantle.

This measurement provides the saddle's seat size.

Many Arena saddles also include sizing information within the serial number, which can help identify the seat size if the original markings are no longer visible. You can learn more about your saddle by reading its serial number.

While measuring a saddle can help identify its size, the measurement alone does not determine whether that saddle is right for you. Rider comfort, balance and support should always be considered alongside the seat size.

What size saddle do I need?

Every rider is unique, which means there is no single formula for determining the perfect saddle size.

Seat size offers a starting point, but finding the right saddle involves considering your position, comfort and riding goals alongside your horse's needs.

A saddle that allows you to feel balanced, secure and connected with your horse can help support confidence and enjoyment in your riding.

For the best outcome, we recommend visiting your local Arena Saddles stockist or working with a qualified saddle fitter. They can assess both horse and rider together and help you find a saddle that supports your partnership now and into the future.

Why might I ride in different sizes cross different saddle styles?

It is not unusual to find that you prefer a different seat size in different saddle styles.

Dressage saddles, general purpose saddles and jumping saddles are designed to support different rider positions and disciplines. Variations in seat depth, shape and design can influence how a saddle feels, even when the seat measurement is similar.

Rather than focusing solely on the number, consider how the saddle supports your position and allows you to maintain balance, comfort and freedom of movement.

The most comfortable size is the one that helps you feel secure and supported while riding.

Does seat size affect how the saddle fits my horse?

Seat size primarily relates to rider comfort and position.

How a saddle fits your horse is a separate consideration and should always be assessed carefully. Horse comfort remains our highest priority, and a correctly fitted saddle should allow your horse to move freely, comfortably and confidently.

Because every horse is unique, we recommend working with a qualified saddle fitter who can assess both horse and rider together. This helps ensure the saddle supports your partnership and provides the best possible outcome for both of you.

Many Arena saddles feature the EASY-CHANGE Fit Solution, helping the saddle adapt as your horse develops and changes shape over time.

Why professional saddle fitting matters

The ideal saddle supports rider confidence while promoting your horse's comfort and wellbeing.

A qualified saddle fitter can assess saddle balance, rider position and horse comfort, helping you select a saddle that suits your needs today while accommodating your horse's development over time.

Regular saddle fit assessments can also help identify changes in your horse's shape, allowing adjustments to be made as needed to maintain comfort and performance.
