Size Guides

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!

A Flymask that Actually Fits!

Finding anything that actually fits a 19 hand Percheron is close to impossible. The largest size from this supplier actually fits, stays on and seems comfortable even in very hot weather. I’ll be trying the rugs soon!

Glad I could find a fly mark big enough for my Shire x dinosaur!! It’s lightweight and breathable the only draw back is that there isn’t masses of room across the forehead and for the eyes. The mask sits a little close to his eyes but other than that lovely product.

Perfect for Clydesdale

This mask has the strongest velco I have come across , purchased a full for Clydesdale , great fit , covers the nose and lovely and light , buying one for my standard size gelding as so pleased with it .

At last a bit fly mask for real heavies

I’ve tried all sorts of masks and ear bonnets but for riding in even those that are xl or draft are just too tight across the ears and eyes
It’s slightly too long in length as he’s a Suffolk and doesn’t have a long nose just very wide
At last one that gives him space for all that the forelock!!!

Ears rather too big

I bought three of these fly masks for our shire mares. Generally I was pleased with them as they are well off the eyes and long enough to cover delicate pink noses that burn with the sun but why are the ears so long? I also bought a cob size mask for our yearling shire and the ears were a much better fit.Generally when upsizing for a longer nosed horse, it is highly unlikely that the ears are any larger than those of the average horse.
