The girth is one of those pieces of equipment that rarely gets the attention it deserves. It sits quietly beneath the saddle, doing one of the most important jobs in the entire tack room — keeping the saddle safely and securely in place — and yet it is frequently chosen on the basis of habit, guesswork, or simply because it came with the saddle. Choosing the correct girth length for your horse is more involved than many riders appreciate, and getting it wrong can have consequences that range from minor discomfort to significant welfare concerns and safety issues.

This guide walks you through everything you need to know about choosing the correct girth length for your individual horse, including how to measure, what to consider, and when to seek professional advice.

Why Girth Length Matters

Before we look at how to choose the correct girth length, it is worth understanding why it matters so much. A girth that is too short will require the saddle's girth straps to be fastened on the lower holes, placing the girth buckles directly beneath the rider's leg and creating a pressure point that causes discomfort for both horse and rider. Over time, this can lead to girth galls, skin soreness, and an uneven or unstable saddle position.

A girth that is too long will require the girth straps to be fastened on the top holes, which reduces the security of the fastening and places the buckles too high — potentially interfering with the saddle flap and the rider's position. A girth that is excessively long may also not provide adequate tension and security, creating a saddle that moves and shifts under the rider.

The correct girth length allows the buckles to sit comfortably in the middle of the girth straps — approximately on the third or fourth hole of a standard set of straps — providing both security and comfort for horse and rider alike.

Understanding Girth Types and Their Sizing

Before measuring your horse, it is important to understand that different girth designs are sized differently and are used with different saddle types, and that the appropriate length for one type of girth may be entirely different from the appropriate length for another.

Standard Shaped Girths

• Standard shaped girths — also known as shaped or contoured girths — are the most commonly used girth type for general purpose and jumping saddles
• They are typically measured in inches in the UK, ranging from approximately 38 inches to 54 inches in standard sizing, with some manufacturers offering additional sizes outside this range for particularly narrow or broad horses
• Standard girths are longer than dressage girths because they attach to the full-length girth straps of a general purpose or jumping saddle, with the buckles sitting approximately halfway down the saddle flap

Dressage Girths

• Dressage girths — sometimes called short girths or Lonsdale girths — are significantly shorter than standard girths and are designed for use with dressage saddles, which have longer girth straps that extend further down the saddle flap
• They are typically measured in centimetres in the UK, ranging from approximately 45cm to 75cm, though sizing varies between manufacturers
• Because dressage saddles have longer girth straps, the shorter girth allows the buckles to sit well below the saddle flap and away from the rider's leg, creating a cleaner and more streamlined contact between leg and horse
• It is important never to use a dressage girth with a standard saddle or a standard girth with a dressage saddle — the proportions are entirely different and the result will be either a dangerously insecure fastening or buckles in entirely the wrong position

Stud Guard Girths

• Stud guard girths are designed specifically for showjumping horses that wear stud shoes, providing a protective pad at the front of the girth that prevents the horse from striking themselves with a stud when they fold their front legs over a fence
• They are sized in the same way as standard girths and the same measurement principles apply

Elastic and Non-Elastic Girths

• Many girths feature elastic inserts at one or both ends, which provide a degree of give and allow the girth to move with the horse's ribcage as they breathe and move
• Girths with elastic at both ends require slightly different consideration in terms of fit, as the elastic will extend under the horse's weight and movement — a girth that appears to be the correct length at rest may behave differently once the horse is moving and the elastic is engaged
• When measuring for a girth with elastic ends, it is worth considering this extension and erring slightly on the shorter side of any borderline measurement

What You Will Need

• A soft tape measure — the type used for dressage or sewing is ideal
• A note of your saddle type — general purpose, jumping, or dressage — as this will determine which type of girth you need
• A helper if possible, particularly if your horse is young or lively
• A level, safe surface on which to work

Step One — Identify Your Saddle Type and Girth Style

• Before you measure, confirm which type of saddle you are fitting the girth to — a general purpose or jumping saddle will require a standard length girth, whilst a dressage saddle will require a short dressage girth
• If you are unsure which type of saddle you have, look at the length of the girth straps — long straps that extend well below the saddle flap indicate a dressage saddle requiring a short girth, whilst shorter straps that sit within or just below the flap indicate a general purpose or jumping saddle requiring a standard girth
• If you have both a dressage saddle and a general purpose saddle, you will need to measure for each separately as the required girth lengths will be different

Step Two — Place the Saddle Correctly

• Place your saddle on your horse's back in its correct fitted position — do not attempt to measure for a girth without the saddle in place, as the position of the saddle directly affects where the girth will sit and therefore what length is required
• Ensure the saddle is sitting level and in its correct position before you begin measuring — a saddle that is too far forward or too far back will give you an inaccurate measurement
• If you are unsure whether your saddle is correctly positioned, our saddle fitting guides in the Knowledge Centre at www.thefittedhorse.com/knowledge-centre can help

Step Three — Locate the Girth Point

• The girth point is the lowest point of your horse's belly in the girth area — roughly behind the horse's elbow, where the girth naturally wants to sit when the saddle is correctly positioned
• On most horses, the girth point sits approximately a hand's width behind the back of the elbow
• Run your hand down the horse's side from the girth straps toward the belly to find the natural groove or lowest point where the girth will settle — this is your girth point

Step Four — Measure for a Standard Girth

• Take your tape measure and hold one end against the bottom hole of the girth strap on the near side of the saddle
• Run the tape measure down the horse's side, under the belly to the girth point, and back up the off side to the bottom hole of the girth strap on the off side
• Note this measurement in centimetres
• To convert to inches, divide by 2.54
• From this total measurement, subtract the distance that will be taken up by the girth straps when fastened at the middle holes — as a general guide, fastening on the third hole of a standard set of straps uses approximately 15 to 20 centimetres of strap on each side, so subtract approximately 30 to 40 centimetres from your total measurement
• The resulting figure gives you an approximate girth length in centimetres, which you can convert to inches for standard girth sizing

Step Five — Measure for a Dressage Girth

• The measurement process for a dressage girth is similar, but because the girth straps on a dressage saddle are longer, the calculation is slightly different
• Hold the tape measure at the bottom of the girth strap on the near side and run it down to the girth point and back up to the bottom of the girth strap on the off side
• Note this measurement in centimetres
• Subtract the amount of strap that will be used when fastened at the middle holes — for a dressage saddle with long straps, this is typically a larger figure than for a standard saddle, so subtract approximately 40 to 50 centimetres from your total measurement
• The resulting figure gives you an approximate dressage girth length in centimetres

Step Six — Check the Result and Allow for Adjustment

• Once you have your approximate measurement, check it against the standard sizing available for the type of girth you are purchasing
• If your measurement falls between two standard sizes, consider the following:
• If your horse is currently in good condition and at their ideal weight, choose the smaller of the two sizes
• If your horse is likely to gain weight or condition, or if they are particularly round or broad through the barrel, choose the larger size
• If the girth has elastic ends, bear in mind that the elastic will extend under use and err slightly toward the shorter size
• Always check that the girth you choose will allow the buckles to sit comfortably in the middle of the girth straps when the saddle is correctly girthed up — if the buckles are consistently at the top or bottom of the straps, the girth is the wrong length

Additional Considerations

Horse Conformation

• Horses with a round, barrel-shaped ribcage — commonly seen in cobs, natives, and good doers — will typically require a longer girth than a horse of similar height with a more athletic, narrower build
• Horses with a well-defined girth groove will hold the girth more securely in the correct position, whilst horses with a flatter, less defined belly may need a shaped or anatomical girth to help keep it in the right place
• Horses with a particularly short distance between the elbow and the last rib — sometimes described as being short in the girth area — may be more comfortable in a shorter, more shaped girth that avoids the sensitive elbow area

Girth Shape and Design

• A straight girth is the simplest design and suits many horses well, but it can press on the elbow area in horses with a short girth groove
• An anatomically shaped or curved girth is designed to curve away from the elbow, providing more clearance in this sensitive area and distributing pressure more evenly across the belly — this design is often more comfortable for horses with a shorter girth groove or those that are prone to girth galls
• A stud guard girth provides additional protection for jumping horses, as described above
• An elastic-ended girth provides more flexibility and movement, which many horses find more comfortable, particularly in horses that are sensitive through the girth area or that hold tension when being girthed up

Girth Material

• Leather girths are durable, traditional, and easy to clean, but they require regular maintenance to keep the leather supple and to prevent cracking — a neglected leather girth can become hard and uncomfortable very quickly
• Synthetic and neoprene girths are easy to clean and often more affordable, but they can cause sweating in some horses and may not provide the same degree of comfort as a well-maintained leather girth
• Fleece and fabric girths are soft and comfortable but can be more challenging to keep clean and may not be suitable for horses that are prone to girth galls or skin sensitivity
• Gel-padded girths offer additional cushioning and can be helpful for horses that are particularly sensitive in the girth area

Signs That Your Girth May Not Be the Correct Length or Design

• Your horse shows discomfort or anxiety when being girthed up — pinning ears, swishing tail, biting, or moving away
• The girth buckles consistently sit at the very top or very bottom of the girth straps
• The girth moves forward or backward during work, failing to stay in its correct position
• Your horse develops girth galls or areas of soreness or hair loss in the girth area
• The saddle shifts or moves during work despite the girth being correctly fastened
• Your horse shows asymmetry in their movement or appears restricted through the shoulder or elbow area

If you notice any of these signs, review your girth length and design and consider seeking professional advice. Our team at The Fitted Horse can assess your girth fit as part of a saddle fitting consultation — visit www.thefittedhorse.com/saddle-fitting to find out more.

Caring for Your Girth

• Clean your girth after every use — sweat and dirt build up quickly in the girth area and can cause skin irritation and girth galls if allowed to accumulate
• Leather girths should be cleaned with a damp cloth or leather cleaner and conditioned regularly with a good quality leather conditioner to keep them supple and comfortable
• Synthetic and neoprene girths can usually be wiped clean with a damp cloth and mild detergent — check the manufacturer's care instructions for the specific product
• Inspect your girth regularly for signs of wear, damage, or weakening of the elastic — a girth that is showing significant wear, has damaged or fraying elastic, or has stitching that is beginning to fail should be replaced promptly
• Store your girth in a clean, dry environment away from direct sunlight and extreme temperatures — UV exposure and temperature fluctuations can accelerate the deterioration of both leather and synthetic materials

When to Seek Professional Advice

Whilst this guide provides a solid foundation for choosing the correct girth length for your horse, there are circumstances in which professional advice is always recommended:

• If your horse has a history of girth sensitivity, girth galls, or anxiety around girthing
• If your horse has an unusual conformation that makes standard sizing guidelines difficult to apply
• If you are purchasing a new saddle and want to ensure that the girth you choose is compatible with the saddle's girth straps and fits correctly with that specific saddle
• If you are changing disciplines and moving from a general purpose to a dressage saddle, or vice versa
• If your horse's weight or condition has changed significantly and you are unsure whether their current girth still fits correctly

At The Fitted Horse, girth fit and length is always assessed as part of our comprehensive saddle fitting service, because we understand that the girth is an integral part of the saddle fit picture rather than an afterthought. A correctly fitted girth contributes to a stable, comfortable, and correctly positioned saddle — and that benefits both horse and rider in every aspect of their work together.
