You need to be careful when measuring your horse for a turnout blanket as they have a tendency to run a little fuller. A blousier effect instead of a traditional fitted look.
Here in the US, we have always measured from the middle of the horse's chest, around the side to the tail to get our "inches" measurement. Round down to the next size smaller for a turnout.
If you are measuring for a WeatherBeeta with the "Freestyle" system that has a much larger tail flap, just measure to the point of the butt. This will get you closer to the true size you should purchase. You want the tail flap top of the seam to be at or as close to the top of the horse's tail.
An inexpensive, but good quality turnout blanket line that is made by WeatherBeeta is there Saxon line of turnout sheets and blankets. You can choose from a 600 or 1200 denier ripstop fabric (the 1200 is tougher than the 600) and also the fill weight. None for a sheet, 180 grams of fill for the medium weight or 250 grams of fill for their heavy weight version.
