It would have been a five if the rug fit had been better. My Quarter Horse normally fits a 6'6" rug, but this rug is very narrow over the shoulders and chest, also quite a tight neck. I would say it is more suitable for a TB type. If you have a stocky/double muscled horse, you might need to go for the next size up, or add a chest expander insert, like I have had to do, to allow freedom of movement of the shoulders. Rug quality appears to be good, shipping etc. was on time.
