The standard size for a toilet drain pipe is 3 inches in diameter, but drains up to 4 inches in diameter are often used. The drain pipe connects to the flange, which mounts the toilet itself, and this flange is usually built to connect to 3-inch, schedule 40 toilet drain pipe.
The toilet flange is the fitting that attaches the toilet to the drain line. The diameter of the waste outlet for the toilet may not match the diameter of the drain pipe -- the toilet may be 4 inches, for example, while the drain line is 3 inches.
