If you’re in the market for a new toilet seat, it’s important to measure your old one first to get an idea of what size you need.

Identify Your Toilet Bowl Shape

There are two main types of toilet bowls: round and elongated. If you’re not sure which type of bowl you have, take a look at the shape of your current seat.

If it’s more oval (curves outwards from the hinges then inwards to a pointed edge), it’s elongated.

Measure Your Toilet Seat Width

Width is the diameter of a toilet seat, so measuring it is pretty straightforward. Just take your tape measure and hold it up to the widest part of the seat (not including the hinges).

For elongated seats, this will be at the front of the seat.

Most toilet seats are around 14 inches wide.

Measure Your Toilet Seat Length

Length is a bit trickier to measure, because it depends on the type of toilet seat you have.

For elongated seats, measure from the center of the bolt also to the front of the seat. Elongated seats are usually around 18 inches long.

For round seats, measure from the center of the bolt holes to the front of the seat. Round seats are typically around 16 inches long.

Measure Your Toilet Seat Height

Height is the distance from the top of the seat to the bottom of the bowl. To measure this, first put your tape measure at the very front edge of the toilet seat. Then, holding it level, measure down to the rim of the bowl.

Most toilet seats are between 2-3 inches high.

Hinge Hole Spacing Measurement

The next measurement you’ll need to take is the spacing of the hinge holes. This will tell you how far apart the bolts need to be in order to fit your new seat.

To measure this, take your tape measure and hold it up to the center of one bolt hole. Then, measure over to the center of the other bolt hole. Most seats have hinge holes that are 5-6 inches apart.

Remember that if you’re shopping for an elongated seat, you’ll need to make sure that the bolts are spaced far enough apart to fit over the larger bowl.
