How to Know If You Need an Elongated Toilet Seat

Elongated toilet bowls typically measure about 18.5 inches from the center of the mounting holes to the front edge of the bowl. Their longer, oval profile provides more front-to-back seating area than a standard round bowl.

Measure Your Toilet Bowl

Measure from the center of the mounting holes to the front edge of the toilet bowl. A standard elongated bowl is typically about 18.5 inches (47 cm) long.

Check the Bowl Shape

Elongated toilet bowls have a longer, more oval profile than round bowls. If the measurement is close to 18.5 inches and the bowl extends farther forward, choose an elongated toilet seat.

Elongated vs. Round Toilet Seats

Elongated Toilet Seats

Elongated toilet seats are designed for bowls measuring about 18.5 inches from the mounting holes to the front edge. Their longer oval shape provides more front-to-back seating area.

Round Toilet Seats

Round toilet seats fit bowls measuring about 16.5 inches from the mounting holes to the front edge. Their shorter profile can be useful where bathroom space or fixture clearance is more limited.

Measure the bowl before selecting a seat, because an elongated seat and a round seat are designed for different bowl dimensions and are not interchangeable.
