What is the standard door knob size?

Selecting the perfect door knob is more than simply a matter of aesthetics. It is important to make sure that the hardware you purchase is of the correct size so that the door can function properly. The standard size for a door knob is a diameter of  2 3/8 inches or 2 3/4 inches and these will fit doors that have a thickness from 1 3/8 inches to 1 3/4 inches.
