Size Guides

Show Coats & Shadbellys

Finding Your Size: While not all show coats are sized equally, there are some basic guidelines that can help you find a well-fitting, comfortable coat.

  • Typically, the 3rd button down should be at the same level as your belly button and the coat tails should rest at the middle of your rear.
  • Jacket sleeves should end at your wrist bone. Keep in mind that if you cannot find a coat that gives you this fit, it is better for sleeves and coat tail to be a bit too long, rather than too short.
  • Make sure that the coat allows enough room for you to move comfortably in the show ring; sit in a saddle if one is available and simulate the position of your arms to assess proper sleeve length.
  • Some manufacturers label using U.S. sizing, while others use U.K. sizing. A general guideline for sizing is that a U.S. size is 4 down from its U.K. equivalent (example: U.K. 12 = U.S. 8).
  • For more detailed measurements from individual manufacturers, please refer to the sizing charts on individual product pages.

Body Protectors/Eventing Vests

Body Protector Notice, Disclaimer, and Warning for Body Protectors/Eventing Vests

Finding Your Size: While individual brands of body protectors may vary slightly in measurements and fit, the following are some basic pointers about the general fit of a body protector.

  • Body protectors should be fitted over light clothing, heavier garments and outerwear should be worn on top.
  • Take measurements of your chest, waist, back length, and over your shoulder (waist-to-waist) and then refer to size charts of specific brands and styles.
  • Before trying on what you feel will be the correct size, loosen the chest and waist fasteners and flex the body protector to loosen the foam. Once on, fasten the chest and waist ensuring a snug fit and make sure there is still room within the fasteners for further adjustment.
  • With the body protector fit securely around your chest and waist, begin to choose the length appropriate for your height. The shoulders and neckline should lie flat against your body; if this cannot be achieved then you may need a shorter length.
  • Check the back length by sitting in a saddle (if possible) and simulating all riding positions. There should be approximately a hand’s width between the saddle and the base of the body protector in the back.
  • At the front, the body protector should reach your breastbone and cover your bottom rib at mid-chest level.
  • For individual size charts, please refer to each style’s specific product page.

Tall Riding Boots

First Steps:

  • Wear the clothing you normally will wear when wearing these boots. 
  • Sit in a straight chair with feet flat on the floor and knees are bend at a 90 degree angle.

To Measure: Repeat the steps below on both legs to ensure there is not one leg that is larger. Make sure to take the larger measurement to ensure both legs fit well in the boots.

  1. Measure the calf around the widest part,
  2. Measure the height from the floor to the back of the knee.
  3. Add 1 1/2 - 2" to measured height to allow for drop as your boot break in.

Riding Helmets

Helmet Notice, Disclaimer, and Warning for ASTM F-1163-01 and 04a/SEI Certified Helmets

To Measure:

  1. Measure 3/4 inch above the eyebrows and around the bump at the back of the head.
  2. Check the size chart to find your size.
  3. Place the forhead in the front of the helmet then, using a rolling motion, push backwards to feel the helmet lock into the base of the skull.
  4. Check for gaps or loose points by running your finger around the rim of the helmet.
  5. Adjust the chin strap to the point 1 finger fits between the strap and your chin.

Head Shapes:

Some helmets come in two shapes: round and oval. Most people have an oval head shape. If you have a rounder head then you may need to try multiple models.

Key things to check for:

  • Snug fit with even, firm pressure around entire head.
  • No specific pressure points or gaps
  • Helmet locks onto the back of the skull
  • Helmet sits level on the head, covering the forehead leaving about an inch above the eyebrows.
  • With the harness unfastened, the helmet should not rock forwards or backwards.
  • The chinstrap should sit right under the chin and gently touch bottom ear lobe, avoiding the throat.
  • A finger should fit between the strap and your chin.
  • Wear the helmet for 5 minutes to reveal any pressure points.
