Klitschko weighed in at 247 pounds on Friday, while the 32-year-old Wach was 251.
The unbeaten Wach will be the first fighter Klitschko has faced who is taller. The 36-year-old Ukrainian is 6-foot-6, while Wach is 6-7½ with a longer reach.
Klitschko goes into his 22nd world championship fight with a 58-3 (51 KOs) record, while Wach has won 27 bouts, 15 by knockout, since turning pro in 2005.
