Gilles Simon is definitly at least 6ft, if not 6'1. He's usually listed at 5'11 and 65-69kg, but doesn't really look all that thin to me. Look at the picture below.Also, in this years wimbledon, he was visibly taller at the net than 182cm Juan Carlos Fererro. Del Potro must be at least 6'7. And I find it hard to understand how tall guys like him and Cilic are listed at 82kg when guys like Djokovic and Federer have similar builds and are shorter by several inches are basically the same weight! Hewitt, as stated seems to be 5'10 or slightly under and Murray looks under 6'3 to me. Any others?
