To work out the correct size for your Mattes Dress Sheet, we need the distance from the highest point of the withers, along the spine to the lower edge of the root of the tail.
We have included both Uk and USA Equivalent Sizes to assist you with the correct size, however there are a couple of additional sizes Mattes provide, that are not convertable to UK or USA, but you can still order those, if your horse is an "inbetween" size.
