Is There A Standard Size For Toilet Seats?

Length

Length is a toilet seat’s most important measurement. Why? Because it is the measurement that is most likely to differ.

Length

As we already know, the width on standard elongated and round toilet seats rarely differs from 14 inches, whereas the length does.

Length

To measure a toilet seat’s length you must first lift up the existing toilet seat (if there is one).

Length

Place your tape measure directly in the middle of the seat post holes and stretch it out until it reaches the end of the bowl – this is your toilet seat length

Width

As you already know, the width of a toilet seat is mostly of standard size in the U.S, but this isn’t always the case.

Width

If you only take one measurement of your toilet the length is definitely the one to take.

Width

The width of a toilet seat is determined by measuring the width of the toilet bowl.

Width

Again, just like the length, to correctly measure the width you must measure from the toilet bowl’s outside edge on one side to the other outside edge.

Width

If this measurement is 14 inches, you have nothing to worry about. If, however, this measurement is larger or smaller than 14 inches you do in fact have a problem.

Seat Post Holes

If your seat post holes are 5.5 inches apart from each other this is a very good thing.

Seat Post Holes

Standard seat post holes are great because they allow you to fit any standard toilet seat that you might have your eye on.

Seat Post Holes

As long as your seat post holes square up to be 5.5 inches apart, you are sitting (on your toilet seat) pretty.
