Ceilings which exceed eight feet in height will require additional CFM. But, if your bathroom is 100 sq. ft. or more in size, the CFM equation is different.

The bath fan calculator is standard guide to help you find the minimum fan rating for your specific bathroom. The higher the bath fan rating the more air can be vented out of the bathroom, which means less moisture and mold build-up.

This fan calculator is typically used to calculate the CFM or cubic feet per minute of air exchange that may be desired in a building. Whether exhausting air or bringing fresh air into a structure, the calculation produced should help to figure out the size of fan (s) required to accomplish the air exchanges needed.
