Ensuring the perfect fit is essential for your horse’s comfort, freedom of movement, and protection against rubbing or slipping. At The Big Horse Shop, we understand that not all horses fit standard rug sizes, which is why we’ve designed rugs specifically for both heavy horses and light to medium-weight breeds.
Our size guide will help you determine the best fit for your horse, whether they have a broad chest and deep barrel or a more light-medium build. With unique size charts tailored to different body shapes, our rugs offer superior coverage and a secure, non-restrictive fit.
You can find the size chart for each rug under the 'Size Chart' tab on the product page, so there’s no need to refer back to this guide. If you need further assistance, our team is always happy to help—visit our Contact Us page to get in touch.
How to Measure Your Horse for the Best Rug Fit
Finding the right rug size is essential for your horse’s comfort and protection. Follow these simple steps to measure your horse accurately:
-
Use a fabric tape measure or twine for precision.
-
Start at the center of the chest, where the rug would fasten.
-
Measure along the side of the body, following the curve of the shoulder, in a straight line to the furthest point of the hindquarters - not all the way to the tail. We recommend placing a broom behind your horse's hind and measuring to that point.
-
For the most accurate results, measure in centimeters and take the measurement 2-3 times.
This measurement serves as a size guide to help you choose the correct rug. If you need expert advice, call us at 01254 279666 we'd be more than happy to help!

Important Information About Sizing & Exchanges
To ensure you can exchange your rug if needed, we recommend trying all items over a clean, thin sheet before use. This helps prevent any dirt, hair, or odors that could affect eligibility for a return or exchange. Items that have been worn or soiled cannot be returned or exchanged should you later feel the size isn't a good fit on your horse.
