The clear opening of a basement egress window should be at least 20 inches wide and at least 24 inches high, and achieve a minimum area of 5.7 sq. ft.âthe smallest opening an average adult male can reasonably crawl through.

An egress window must have a clear opening of at least 5.7 sq. ft.âlarge enough to allow a firefighter, with equipment, to enter the home through the window. In addition, the window must be at least 20 in. wide and 24 in. high (while still meeting the 5.7-sq.-ft. requirement).
