How to measure for a horse blanket or sheet

A poorly fitted blanket can cause rubs, restrict movement, or leave your horse exposed to the elements. According to veterinary research on equine thermoregulation, improper blanketing can lead to overheating or insufficient warmth, both of which stress your horse's natural temperature regulation. Getting the measurement right the first time saves you from the hassle of returns and ensures your horse stays comfortable through every season.

At Kensington, we've spent over 70 years crafting equine protective gear. We've learned that the perfect fit starts with a simple measurement, but there are nuances that can trip up even experienced horse owners. Here's exactly how to measure your horse for a blanket or sheet, what tools you need, and how to avoid the common mistakes that lead to ill-fitting blankets.

What you'll need to measure your horse

Before you start, gather a few simple items. Having everything ready makes the process smoother and more accurate.

A soft fabric measuring tape. This is essential. Rigid metal tapes don't contour to your horse's body and will give you inaccurate readings. A flexible, cloth-style tape measure works best.

A helper. Measuring is much easier with one person holding the tape at the chest while the other extends it toward the tail. Solo measuring often results in shifting tape and inconsistent readings.

Level ground. Your horse needs to stand squarely on flat, even ground for the most accurate measurement. Uneven terrain throws off the alignment and can add or subtract inches from your result.

An alternative measuring method. If you don't have a fabric tape measure handy, use a piece of string or baling twine. Mark your measurement point, then lay it flat alongside a standard ruler or rigid tape measure to get your final number.

One more thing: make sure your horse's calm and relaxed before you begin. A fidgety horse makes accurate measuring nearly impossible.

Step-by-step: How to measure your horse for a blanket

Getting an accurate measurement only takes a few minutes, but precision matters. Follow these steps to make sure your blanket fits perfectly.

Step 1: Position your horse correctly

Stand your horse squarely on level ground. This means all four feet should be positioned evenly, not stretched out or bunched together. Make sure your horse's relaxed and calm. Have your helper ready at the chest with the end of the measuring tape.

Step 2: Find your starting point

Stand at your horse's shoulder and locate the center of the chest, just above where the front legs meet. This is your starting point. It's where the front closure of the blanket will sit when properly fitted.

Starting too high or too low can throw off your measurement by several inches, especially on larger horses. Always measure from the center of the chest, not the top of the withers.

Step 3: Measure along the body

While your helper holds the measuring tape in place at the chest, stretch it along the widest part of the shoulder, over the barrel, and stop at the point where the tail begins. For Kensington blankets, measure to the point of the buttocks where the "cheek" meets the tail.

Keep the tape snug but not tight, following the horse's natural contour around the body rather than cutting diagonally across. Keep the tape level and taut. Do NOT form-fit the tape snugly against the body contours, as this adds unnecessary inches.

This curved line represents how the blanket will sit on the horse. Measuring straight or diagonally across the side will make your blanket too short or too long.

Step 4: Record your measurement

The number of inches is your horse's "true size." This measurement translates directly to the blanket size you should try on your horse. Most blankets are sized in 3-inch increments (72", 75", 78", and so on).

If your horse's measurement falls between sizes, round up to the next size for a comfortable fit. For example, if your horse measures 75 inches, order a size 75 blanket. If the measurement lands between 74 and 75 inches, go with a 75.

Blankets that are slightly too small can pull across the shoulders and restrict movement, while a slightly larger size provides flexibility for layering or thicker winter coats.

Note on European-cut blankets: If you're purchasing a European-cut blanket, reduce your measurement by 1-2 inches, as these styles typically run larger in the body. 

Horse blanket size chart

Once you've measured, use this chart to find your horse's corresponding blanket size. Keep in mind that build matters more than height. A stocky horse may need a larger size than the height chart suggests, while a narrow-built horse might need a smaller size.

As one experienced horse owner noted on the Chronicle of the Horse forum: "I have known 15 hand horses built like dachshunds that took 81" blankets. I have also known a short-coupled 17 hand TB that took a 75" blanket."

This variation is why measuring is always more reliable than going by height alone. Dover Saddlery recommends always measuring rather than estimating based on height or weight.

Kensington offers specialized cuts for horses that don't fit standard sizing, including Miniature, Pony, and Draft horse options. Our size charts provide detailed measurements for each specialized fit. 

How to check if your blanket fits properly

Even with the correct size, a horse's conformation affects how a blanket fits. Here's how to check your blanket once it's on your horse.

Front closure check

The front closure should allow for natural movement without gaping or pulling. Use the two-finger rule: you should be able to slip two fingers between the blanket and your horse's chest. If you can't, the blanket is too tight. If you can fit more than that easily, it may be too loose.

Shoulder fit

The blanket should lie smoothly across the shoulders without pulling or wrinkling. Look for gussets that allow freedom of movement. If you see rubbing or pressure points, especially after the horse has worn the blanket for a few hours, you may need a different style or size. PetMD notes that shoulder rubs are one of the most common signs of an ill-fitting blanket.

Body coverage

The blanket should cover the barrel completely, stopping just before the tail (or covering it, depending on your preference and the blanket style). The drop should be even on both sides. If one side hangs lower than the other, the blanket may be shifting or the fit may be off.

Surcingle and leg straps

Surcingles should be snug but not tight. Allow a hand's width between the straps and your horse's belly. Leg straps should cross in an X pattern under the tail for security. They should not be so tight that they restrict movement, nor so loose that they hang dangerously low.

If you notice rubbing, pressure points, or slipping, your horse might need a different fit style, not necessarily a different size.

Common measuring mistakes (and how to avoid them)

Even a small error in measuring can make a big difference in how your blanket fits. Here's what to avoid.

Mistake 1: Form-fitting the tape

Following the body contours instead of measuring straight across adds inches to your measurement. This is one of the most common errors, and it often results in ordering a blanket that's too large.

Fix: Keep the tape level and taut, not snug against the body. The tape should follow the general line of the body without pressing into the contours.

Mistake 2: Measuring to the wrong endpoint

Some methods say to measure to the center of the tail. Others say the edge. Some say the middle of the tailbone. This variation is why the same horse can measure several inches differently depending on who's doing the measuring.

Fix: Follow your brand's specific instructions. For Kensington blankets, measure to the point of the buttocks where the "cheek" meets the tail. As Schneiders notes in their measuring guide, different brands may have slightly different endpoints, which can result in several inches of variation between methods.

Mistake 3: Rounding down between sizes

A too-small blanket restricts shoulder movement and causes rubs. It can also put pressure on the withers and chest, creating discomfort and potential sores.

Fix: Always round UP to the next size if between measurements. A blanket slightly too large is always preferable to one that's too small.

Mistake 4: Measuring a moving horse

Horses that shift, fidget, or aren't standing square give inaccurate readings. Even a slight shift in weight can change the measurement by an inch or more.

Fix: Make sure your horse's calm, standing square on level ground. Take your time and don't rush the process.

Mistake 5: Using the wrong measuring tool

Rigid metal tapes don't contour properly and can slip or bend, giving inconsistent readings.

Fix: Use a soft fabric measuring tape or the string alternative method described earlier.

Understanding blanket and sheet differences

Before you buy, it helps to understand the difference between blankets and sheets. The measuring method's the same for both, but the intended use differs.

What is a horse sheet?

A horse sheet is lightweight with no fill. Sheets are used for protection from sun, rain, or to keep your horse clean before a show. They're ideal for mild weather when warmth isn't needed but protection is.

What is a horse blanket?

A horse blanket contains fill (insulation) for warmth. Blankets come in various weights:

• Lightweight: 100-180g fill (like a sweatshirt)

• Medium weight: 150-280g fill (like a lined jacket)

• Heavyweight: 300-400g fill (like a ski jacket)

• Ultra heavyweight: 400g+ fill (for extreme cold)

When to use each

Use sheets for mild weather, sun protection, or keeping your horse clean before shows. Use blankets for cold weather, clipped horses who've lost their natural coat, or seniors who need extra warmth to maintain condition. 

Tips for hard-to-fit horses

Not every horse fits neatly into standard sizing. Here are tips for horses with unique body types.

Deep-shouldered horses

Look for V-front or Surefit designs. These provide extra room at the shoulder and prevent the blanket from pulling or restricting movement.

Narrow-chested horses

Disc front closures work well for horses with narrower chests. They prevent gaping at the chest and help the blanket stay centered.

High-withered horses

Cutback neck designs reduce pressure on the withers. Wug styles can also help prevent rubbing on high-withered horses.

Stocky or bulky builds

You may need to size up beyond what the height chart suggests. XL cuts offer 20% deeper neck and sides to accommodate broader builds.

Growing horses

Consider sizing up for growing room if you have a young horse. Adjustable features like multiple front closure settings can help extend the usable life of the blanket.

Frequently Asked Questions

What is the most accurate way to measure for a horse blanket or sheet?

The most accurate method is to use a soft fabric measuring tape, starting at the center of your horse's chest where the neck meets the chest, running across the widest part of the shoulder, and ending at the point of the buttocks where the tail begins. Keep the tape level and taut without form-fitting to the body contours.

Should I round up or down when my horse measures between sizes for a blanket or sheet?

Always round UP to the next size if your horse falls between measurements. A blanket that is slightly too large is preferable to one that is too small, which can restrict shoulder movement and cause rubbing.

Can I use the same measuring method for both horse blankets and sheets?

Yes, the measuring method is identical for both blankets and sheets. The difference lies in the weight and fill of the garment, not the sizing. Sheets are lightweight with no fill, while blankets contain insulation for warmth.

Why do different brands recommend different ways to measure for a horse blanket or sheet?

Each brand designs their blankets with different cuts, proportions, and fits. Some brands account for their specific patterns by recommending slightly different measuring endpoints. Always follow the measuring instructions provided by the specific brand you're purchasing from for the best fit.

How do I know if my horse's blanket or sheet fits properly after I measure and buy it?

Check that the front closure allows two fingers between the blanket and chest, the shoulders lie smooth without pulling, the body covers the barrel evenly, and surcingles allow a hand's width of space. The blanket should stay centered when your horse moves and not shift or twist.

What tools do I need to measure my horse for a blanket or sheet?

You need a soft fabric measuring tape (rigid tapes don't contour properly), a helper to hold the tape at the chest, and level ground where your horse can stand square. If you don't have a fabric tape, you can use string or baling twine marked and then measured against a ruler.
