What size vent is a bathroom fan?

Can a bathroom fan be vented out a wall?
The fan exhaust must vent directly to the exterior of the home. Do not put the vent termination in a roof overhang or soffit. Don’t put it on a wall near or under a roof overhang. The moist air that’s belched out by the fan can be sucked right up into the open soffit vents and be drawn into your attic.

Do I need a more powerful bathroom fan?
You want one with a cubic-feet-per-minute (cfm) rating that’s high enough to pull all the air out of your bathroom in 7½ minutes. To determine the fan’s minimum cfm, divide your bathroom’s volume by 7.5. Go with a higher cfm if the duct run exceeds 20 feet or has more than one elbow.
Can you use PVC pipe to vent a bathroom fan?
