The 3-Inch Flange

A 3-inch flange measures the same size as the schedule 40 pipe most likely used in your toilet drain. This flange doesn't give you the wiggle room of a 4-inch flange, which results in a bit more pressure on the flange when you flush the toilet. This is a known issue, however, so 3-inch flanges can handle the extra load.

The 4-Inch Flange

The 4-inch flange installs on both 4- and 3-inch drainpipes. This flange is manufactured so it fits over the top of a 3-inch pipe (in other words, the pipe slides into the flange), or the flange fits inside a 4-inch pipe (the flange slides into the 4-inch pipe).
