How to Measure Horse Rugs: A Step-by-Step Guide to Find the Perfect Horse Rug Fit

Horse Rugs: Why Fit Matters

It’s very important to get the correct fit for your horse rug – not just for their comfort, but also for their wellbeing. Poorly-fitted rugs can cause rubbing, irritation, and chafing – which can become serious chafing and dry skin develops into sores and infections.
Avoid a costly vet visit by getting the fit right the first time! A well-fitted rug provides warmth during the colder months or sun and fly protection in the summer, without restricting movement. Our guide is designed to take the guess work out of choosing what size rug you need for your horse.

Understanding Horse Rug Sizing

To get the right size for your horse rug, you’re going to need to measure your horse. Then, choose the size that corresponds to your horse’s measurements (remembering that rugs are often adjustable but only to a certain extent – you’re not going to want to choose a size that’s more than a few centimetres over). Sizes in Australia and New Zealand are as follows.

Tools Required for Measuring Your Horse

Measuring your horse is easy! You will need:

Measuring Tape: Use a flexible measuring tape to accurately measure the length from the centre of your horse's chest to the point of their hindquarters where the rug will end.

Assistant or Helper: Having someone to help you can make the process easier, especially if your horse tends to move around.

Stable Area or Controlled Environment: Choose a stable area or a controlled environment where your horse is calm and relaxed.

Step-by-Step Measuring Guide

Option 1: Measure Your Horse Directly (recommended!)

This is the best method to use to get the correct rug size.

1. Using a tape measure that has imperial measurements (feet and inches, standard units for horse rug sizing) measure in a straight line from the centre of the horse's chest (where the top chest buckle would sit), around the shoulder, along the side of the belly to the furthest rear point of the rump, or where you expect the rug to finish.
2. Be sure not to measure around the tail, as this will add a few extra inches and likely throw off your sizing.
3. Once you’ve got your measurement, use the chart above to determine what size you’ll need. Sizing runs in 3inch intervals, so you may need to allow an extra inch or so.
4. To check you’ve sized up your horse correctly, pull your tape to the corresponding measurement for that horse rug (so if you’ve determined your horse requires a 6’0 rug, you would pull your tape to read 6’0 or 183cm) and using the method described in step 1, measure your horse and determine that the rug will finish where you expect it to. Compare it with above and below sizing to ensure you’ve got the correct fit.

Option 2: Measure an Existing Rug that Fits

Generally, it’s better to measure your horse rather than an existing rug that fits, as measuring the rug doesn’t account for if your horse has gotten bigger or smaller – or if that rug has stretched or shrunk. If possible it’s better to get both measurements rather than one or the other. Nevertheless, you can use this method to determine horse rug size.

1. Measure the length of the rug by measuring from the front edge of the rug, between the two chest straps, along the length of the rug, with the gusset closed to the rear edge of the rug.

2. Be sure to choose a normal cotton or mesh paddock rug (or similar) rather than a waterproof turnout rug. Turnouts horse rugs tend to be slightly longer to cater for chest overlap, and this will complicate the way you need to measure your existing horse rug.

How to Check a Rug Fits Your Horse

Once you’ve got your new horse rug, check to make sure it fits.

1. Put the rug on your horse, it should sit forward and in front of the wither.
2. The top chest buckle should be fastened to the tightest or second tightest hole. If you are using the third hole or more, it may suggest the horse may need a larger rug size.
3. The rug should sit firmly around the neckline and chest.
4. Leg straps should be loose enough to prevent chafing - but not hanging down low.
5. Surcingles should be adjusted so that they allow a hand's width between straps and belly.
6. The seam where the tail flap attaches to the rug should sit on top of the tail. If it sits beyond the tail, the rug is too big. If it sits up in front of the tail, the rug is too small.

Fitting Horse Rugs: Common Mistakes to Avoid

Fitting a horse rug may seem straightforward, but several common mistakes can compromise your horse's comfort and well-being.

• Guessing the Size
Always take your horse’s measurements, or measure an existing rug that your sure fits well, prior to purchasing a new horse rug.

• Neglecting Adjustability Features
Many horse rugs come with adjustable features such as surcingles, leg straps, and shoulder gussets. Neglecting to adjust these features according to your horse's body shape and condition can compromise the fit and lead to discomfort.

• Poor Rug Placement
Incorrect placement of the rug can cause it to shift, slide, or bunch up, leading to discomfort and even risking injury. Ensure that the rug sits snugly along your horse's back and doesn't impede movement or rub against sensitive areas.

• Ignoring Signs of Discomfort
Monitor your horse for signs of discomfort caused by the rug – particularly with new rugs. Poorly fitted rugs can lead to skin irritation, so keep an eye out for any signs or symptoms.

• Choosing Style Over Functionality
Ensure that the rug provides the necessary warmth, protection, and freedom of movement, rather than solely focusing on its appearance.

Caring for Your Horse Rug

Proper cleaning can prolong the life of your horse rug and prevent issues such as wear, tear, and bacterial growth.

1. Regularly Clean Your Rug
   Regularly cleaning your horse rug is crucial for removing dirt, sweat, and debris that accumulate over time. Use a stiff brush or broom to loosen dirt and mud, then hose down the rug with water to remove surface grime.

2. Deep Clean When Required
   For deeper cleaning, follow the manufacturer's instructions for washing the rug. Avoid using harsh detergents, bleach, or fabric softeners, as they can damage the fabric and strip away waterproofing or breathable coatings. Opt for gentle, horse-safe detergents to preserve the integrity of the rug.

3. Rinse Thoroughly
   After washing your rug, ensure you’ve rinsed it thoroughly to remove all traces of detergent from it. Residual detergent left on the fabric can irritate your horse’s skin or even cause allergic reactions – so this is an important step.

4. Dry it Out
   Hang the rug to dry in a well-ventilated area away from direct sunlight. Avoid using a tumble dryer or exposing the rug to excessive heat, as it can damage the fabric and waterproofing properties.

5. Re-proof It
   Periodically reproofing your horse rug is essential to keep it waterproof. Use a waterproof spray or wash-in reproofing solution.

6. Check for Damage
   Regularly inspect your horse rug for signs of damage, such as tears, loose stitching, or damaged straps. Promptly repair any minor damage to prevent it from worsening and compromising the rug's effectiveness.

7. Store Properly
   When not in use, store your horse rug in a clean, dry, and well-ventilated area. Avoid storing it in damp or humid conditions, as it can promote mould and mildew growth.

8. Rotate Rugs
   If you have multiple rugs for different weather conditions, rotate them regularly to distribute wear evenly and prolong their lifespan. Alternating between rugs also allows you to clean and maintain them more effectively.

9. Professional Cleaning and Repairs
   For stubborn stains, deep cleaning, or significant damage, consider seeking professional cleaning or repair services. Professional rug cleaners have the expertise and equipment to thoroughly clean and repair horse rugs, ensuring they remain in good condition.
