As I was told, it depends on the girth of the man. The bigger you are, the more material you need. Most guys use 5-6 yards for a great kilt, but if you are bigger than that, you need to call your kilt company and tell them what your hips are, and they can advise you on how much material you need. Your 11 ounce material is probably 59-61 inches wide, and the 13 ounce is probably 54-60 inches wide. You want to make sure you have enough material and width in your tartan, because you are wrapping it around you. The people I have found best to answer these questions is: Alex Cameron of the Wild Highlanders in Tampa, Florida. They know alot about the great kilt, and also make weapons for you like the Lochaber Axe,etc. Speak to either Alex or Scott. Their number is: (813) 854-5611 or visit their website at:www.wildhighlanders.com
