Answers:    Well, that doesn't sound right to me because I'm 5'9" and my foot hang stale the end of a twin. However, I've done for a while research and just going on for every site says 73-75" for a standard twin and 80" for a long twin. possibly I get longer when I stretch out. So, for your grill, it appears to be true.
