Which of the following is the typical minimum mezzanine clearance height?

• A. 6 ft 8 in
• B. 7 ft
• C. 8 ft
• D. 7 ft 6 in

Answer: (B)

The key idea is headroom above a mezzanine—the vertical space available for people and equipment on and around the mezzanine. In most typical designs, seven feet of clearance is used as the minimum. This height provides comfortable standing space for an average person, reduces the need to duck or bend, and accommodates common overhead elements like lighting, sprinklers, and small equipment during routine movement. The other options are generally too low for regular mezzanine use: six feet eight inches is a common minimum for certain corridors or egress paths, but not for mezzanines where people walk and work; seven feet six inches and eight feet are higher baselines that are used in special cases but aren’t the standard minimum in most situations. So, seven feet is the standard minimum mezzanine clearance.
