Which blanket cut fits my horse's shape?

Look at his build before you look at a size chart. A tape gives you a number, but it doesn't tell you the cut, and the cut matters as much as the size. Ask four things. Are his withers high, or does he have almost none? Is he narrow or wide through the chest and shoulder? Is he a horse, a draft, a pony or a cob? Does his neck tie in high or low?

Brands name their cuts in their own words (standard, high neck, combo, XL, pony), so a size that fits in one line may not fit in the next. Horseware, for example, describes its Wug as a higher, snugger neck that clears high withers, its Surefit with V-Front as extending past the withers, and its Optimo as having a dart above and behind the shoulder for big-bodied, broad-shouldered horses.

The chart below comes from what riders report on each build, plus Horseware's own size guide for the XL and pony figures. Treat each row as a place to start. Fit still varies from horse to horse.

A high-withered horse needs a high-neck or combo-neck cut that is shaped over the withers. A straight standard cut that sits snug enough not to slip tends to pull tight across the withers and mane, and one loose enough to clear them can slide on a narrow frame. Riders with Thoroughbreds most often name the Rambo Original and Rhino Plus for this build. Horseware describes its Wug cut as a higher, snugger neck that clears high withers.

A high neck is not a guarantee. The same horse can fit one cut from a brand and rub in another, so check his withers after the first few days of turnout. If you see rubbed hair or a sore spot, have your vet look at it before you try another blanket.

A narrow horse needs a narrower cut with front closures you can take in. In a generous cut he gets a blanket that gapes at the shoulder and slides to one side, which lets rain in and rubs where it shifts. Among the Horseware lines, riders describe Rhino as narrower through the chest and shorter in the drop than Rambo, and say the Rambo Wug suits narrow, thin-necked horses.

Narrow horses split riders more than any other build. One rider's perfect fit gapes on the next horse, so try the cut on before you take the tags off. Seniors that have lost topline often move into this group.

Wide-chested horses need room across the shoulder, and big-shouldered warmbloods need depth. Stock-type horses such as Quarter Horses and Paints have the opposite problem to a Thoroughbred. With a wide chest and little wither to hold the blanket in place, a narrow cut is tight across the chest and slips back. Riders say large shoulder gussets make the difference, along with a chest closure you can let out.

For the widest horses, riders name the Rambo Optimo. Horseware describes the Optimo as having a dart above and behind the shoulder that follows movement so the blanket stays put, and recommends it for big-bodied, broad-shouldered horses.

A warmblood with a big shoulder needs deep gussets so the shoulder can move without rubbing, and a drop long enough to cover the belly. A few riders find even a generous cut too shallow on a big warmblood, with the belly showing below the line, so check the drop as well as the chest when it arrives.

Drafts need an XL cut, and ponies and cobs need a shorter body, not a scaled-down horse blanket. A draft needs width through the chest and shoulder and enough drop to cover his sides. Riders say the hard part is fitting the front and the back at once. Horseware's XL cut is 20% deeper in the neck and 10% deeper in the body. A horse between sizes may find the bigger one gapes at the chest while the smaller one is tight at the shoulder.

Horseware cuts its pony sizes with a body 10% shorter so the blanket doesn't restrict movement, and a pony cut keeps the drop from hanging past the knee. Short-backed cobs and wide-barreled ponies often need a size chosen by chest width, not height. Leg straps are the other pony complaint, since on a small pony they are often too long, and a long tail flap can trap manure.

Size ceilings vary by brand. As of October 2026, our Amigo and Rambo lines go up to 90 inches, WeatherBeeta, Shires, Rhino and Centaur up to 87, and Horze and Equinavia up to 84.

Stand him square on level ground and measure from the center of his chest, across the point of the shoulder, to the center of his tail. Use a soft tape. Guides name slightly different end points for the tape, so follow the instructions for the brand you are buying.

Horseware's guide says to take 4 inches (10 cm) off that number before you read its chart. Most other brands read the measurement as is, and general guides say to round up when you fall between sizes. Horseware also recommends sizing down on the Rambo Optimo, which is cut for a larger horse, so 'size up' is not a rule for every line.

Brands do not run the same. Riders say Rambos run about a size large: one horse wears an 81 in the Rambo Original but a 78 in the Optimo. Height is a poor guide, since a long-backed horse can need a bigger blanket than his hands suggest. The EU label on Horze is not a centimeter length, so shop Horze by the US number on its label.

Check the withers, shoulder, chest and tail before you take the tags off. Our horse blanket guide lists the checks riders use. You should be able to slide a hand flat between the front of the blanket and the withers. The chest closure should not gape or pull. Shoulder gussets or shaped panels should leave room for a natural stride. The blanket should cover the hindquarters to the top of the tail without hanging past the point of the buttock.

Cross surcingles should be snug enough to stay put, with about a hand's width of room, and leg straps should let you fit two fingers through each loop. Penn State Extension says to check fit regularly because poorly fitting straps can cause rub marks or sores, and to take a continuously worn blanket off regularly to look for damage and twisting. Rutgers says to take it off at least once a week to groom and to check for weight changes, skin problems and blanket rubs.

Hair loss, sores or swelling under a blanket are a job for your vet. If you are weighing weight as well as cut, try the Blanket Weight Calculator or the Blanket Selector. Wondering how warm a blanket you need? See what weight blanket your horse needs, and for wet weather, can I blanket a wet horse?
