Show Coat Sizing: How to Measure and Pick the Right Size

Chest, waist and sleeve measuring steps, plus size charts from RJ Classics, Tredstep, Kerrits and Horze.

Measure your chest over a show shirt, plus your waist and sleeve, then match the chest number to the maker's own chart. Sizes differ by brand, and some makers add short, regular and long lengths by height, plus plus-size and petite charts.

How to measure for a show coat: chest, waist and sleeve

Measure your chest, waist and sleeve while wearing a show shirt, and let the chest number set your starting size. Show coat sizes are not the same from one brand to the next, so the tape matters more than the number on your last coat. For how a coat should sit once it is on, read how a show coat should fit.

  1. Wear the shirt you show in, and stand straight with your arms relaxed at your sides.
  2. Chest: wrap the tape around the fullest part of your chest, under the arms and across the shoulder blades. Keep it firm but not tight.
  3. Waist: measure at your narrowest point. Some charts, such as Horze's, also list hip at the broadest point.
  4. Sleeve: measure from the shoulder seam to the wrist, as Tredstep's chart does, or from shoulder to wrist as Horze's note says.
  5. Where a chart lists body length, as Tredstep's does, measure from the highest point of your shoulder. Charts list body measurements, so measure yourself, not an old coat.

Show coat size charts by brand

Use the chart from the maker of the coat you are buying, because each maker prints its own numbers. Below are charts from RJ Classics (a coat chart with length by height, a ladies plus chart and a men's chart), Tredstep (with a US, UK and EU converter), Kerrits (women's and petite) and Horze (body measurements). Find your chest figure first, then check sleeve and length where the chart lists them.

  • All measurements in the table are body measurements, not actual garment measurements.
  • Measure circumferences using a tape measure, as follows: chest size where the chest is largest (A), waist size at the narrowest part (B) and hip size where the hips are broadest (C).
  • The measuring tape should sit firmly around the body, but not too tight.
  • Arm length is measured from the shoulder to the wrist (D).

Between sizes: US vs EU numbering and short, regular or long

When you fall between two sizes, compare the sleeve and body length figures for both, and where a maker offers lengths, choose the length by height first. The RJ Classics show-jacket chart sets Short at 5'0" to 5'6", Regular at 5'7" to 5'11" and Long at 6'0" and above. Tredstep's converter pairs US 2 with EU 34 and UK 6, and US 10 with EU 42 and UK 14, and Horze's chart runs on European sizes 32 to 46. Makers number differently, so convert with the chart for the coat in your cart.

Plus size, long arms and short torso show coats

Plus sizes, long lengths and petite lengths each have their own chart, so start there instead of the standard row. The RJ Classics ladies plus chart covers tops 1X to 2X and coat sizes 18W to 24W, with chest from 44 to 52 inches and waist from 39 to 48 inches. Kerrits prints a petite chart next to its women's chart, and the petite figures are shorter than the standard ones for the same sizes. Riders tell us sleeve length is the sticking point for long arms, and the two reviews below both describe finding enough of it. If your chest and waist land on different rows, let the chest set the row and check the waist, sleeve and length figures before you choose.

Kerrits Show Coats

After getting over my initial obsession with the stretchy fabric, I checked myself out in the mirror. And I liked what I saw…which was a fit that flattered my curves, without being too tight or too loose. Plus, I was also happy to find that the sleeves are long enough for my arms (with a 5’9” frame, sometimes finding sleeves that are long enough for my arms can be challenging).

RJ Classics Melody Mesh Show Coat

Speaking of fit…I ended up with a 12 long because…well…I’m long. Having the extra length in the sleeves is fantastic for me as the only coat I have that has sleeves long enough was my semi-custom shadbelly. Being able to buy something off the rack that fit well is beyond delightful. The material of the mesh is stretchy enough to accommodate my large arms…and the shoulders are wide enough for me that I don’t look like I’m wearing a coat that is too small. There is also a zipper along with the buttons, so if you do go for a tighter fit, it will keep you looking tidy and not having and gaping from boobs or belly.

RJ Classics Show Coats

I love my orange label coats. They do fit better than the grey label and are lighter/better fabric.

RJ Classics Melody Mesh Show Coat

First off I want to give a huge shout out to R. J. Classics for their sizing. This coat comes in short, regular and long lengths…in sizes 00 – 16. I mean…their sizing covers ALMOST everyone. It’s very extensive. Also major props to them on the easy care level of this jacket. It came out looking brand new from the washing machine. No wrinkling. No loss of shape. I washed it as the instructions stated and it came out looking exactly as it came new in the bag.

Show Coat Sizing FAQ

How do I measure for a show coat?

Measure around the fullest part of your chest while wearing a show shirt, then your waist at its narrowest and your sleeve from shoulder seam to wrist. Keep the tape firm but not tight, and measure your body, not an old coat. Match the chest number to the chart above.

Close

What size show coat do I need if I am between sizes?

Compare the sleeve and body length figures for both sizes, and where the maker offers short, regular and long, pick the length by your height first. Charts differ by maker, so read the chart for the exact coat. Measure once more before you order.

Close

Is there a plus size show coat size chart?

Yes. The RJ Classics ladies plus chart covers tops 1X to 2X and coat sizes 18W to 24W, with chest from 44 to 52 inches and waist from 39 to 48. Kerrits also prints women's sizes through 2X. Measure your chest and waist, then find your row.

Close

How are US and EU show coat sizes different?

Tredstep's converter pairs US 2 with EU 34 and UK 6, and US 10 with EU 42 and UK 14. Other makers number differently, and Horze's chart runs on European sizes 32 to 46. Convert with the chart for the coat you are buying.

Close

Do show coats come in long and short lengths?

Some do. The RJ Classics show-jacket chart sets Short at 5'0" to 5'6", Regular at 5'7" to 5'11" and Long at 6'0" and above, and Kerrits prints a petite chart. For other makers, check each chart for length figures before you order.
