How to Measure Your Horse for a Blanket

A properly fitted horse blanket helps keep your horse comfortable, protected, and able to move freely. A blanket that is too small can rub the shoulders, chest, and withers. A blanket that is too large can shift, slip, or create safety concerns.

Measuring correctly before buying or fitting a blanket is one of the best ways to prevent rubbing, discomfort, and poor performance.

Step 1: Use a Soft Measuring Tape

Use a flexible tape measure long enough to reach from the front of your horse’s chest to the back of the hindquarters. If needed, use a second person to help hold the tape straight and level.

Your horse should be standing square on level ground.

Step 2: Measure From Point A to Point B

Measure from:

Point A: the center of the chest
Point B: around the side of the body to the point just under the tail, at the edge of the buttock

The number of inches equals your horse’s blanket size.

Example:
If your horse measures 78 inches, you will usually start with a 78-inch blanket.

Step 3: Round to the Nearest Blanket Size

Horse blankets are usually sold in even-numbered sizes, such as:

If your horse measures between sizes, check the brand’s sizing guidance. Some horses do better sizing up, while others need a more tailored fit.

Not Every Horse Fits the Same

Blanket size is not only about inches. Your horse’s conformation matters too.

A horse with high withers, broad shoulders, a deep chest, or a shorter back may need a different blanket style than another horse with the same measurement.

For example, horses with high withers may need a blanket designed to provide extra clearance so the blanket does not press, rub, or create sore spots.

Other fit considerations include:

shoulder width
chest shape
topline
wither height
body depth
overall build

This is why two horses can measure the same size but still need different blanket cuts or styles.

Check the Fit Before Turnout

Once the blanket is on your horse, check that it:

sits comfortably across the chest
does not pull tightly at the shoulders
allows free movement
does not press on the withers
stays centered on the body
covers the hindquarters without hanging too low
allows straps to fasten securely without being too tight

You should be able to slide your hand under the front of the blanket without excessive pressure.

Watch for Signs of Poor Fit

A poorly fitted blanket may cause:

shoulder rubs
wither sores
hair loss
shifting or slipping
restricted movement
pressure marks
blanket damage

If you notice rubs or repeated shifting, the size, cut, or adjustment may not be right for your horse.

Measuring for a Neck Cover

If your horse needs extra protection from wind, rain, or cold, a neck cover may be helpful.

Neck cover size should coordinate with the blanket size and your horse’s neck length and build. A neck cover should provide coverage without being too tight, pulling on the blanket, or restricting movement.

Proper Way to Attach a Neck Cover

When connecting a neck cover to a blanket:

Lay the neck cover smoothly along the horse’s neck.
Attach the cover to the blanket using the built-in clips, straps, or Velcro tabs.
Make sure both sides are attached evenly.
Fasten neck closures snugly but not tightly.
Check that your horse can lower its head comfortably.
Make sure the cover does not pull the blanket forward onto the withers.

A neck cover should move with the horse, not against the horse.

Final Fit Check

After your horse wears the blanket for a short time, remove it and check for:

warm or sweaty areas
rubbing
pressure marks
shifting
hair loss
damp spots

A good blanket fit protects your horse while allowing natural movement and comfort.

Taking time to measure correctly and consider your horse’s individual build helps prevent discomfort and extends the life of the blanket.
