How to Measure for a Toilet Seat

Bolt Spread

This is the distance between the two holes where the seat attaches to the toilet bowl with bolts. It's the most crucial measurement for ensuring a secure and proper fit. Sometimes, bolt spread can be tricky to measure accurately, especially if there’s limited access. If you encounter any challenges, consult with a professional plumbing repair service.

How to Measure Bolt Spread

• Identify the two bolt holes at the back of the toilet bowl where the seat attaches.
• Place the end of your measuring tape on the center of one bolt hole.
• Extend the tape measure to the center of the other bolt hole.
• Record the distance in inches or centimeters. This is your bolt spread measurement.

Bowl Length

This is the distance from the front rim of the toilet bowl to the center of the mounting bolts. It determines how far the seat extends over the bowl and can impact comfort, especially legroom.

How to Measure Bowl Length

• Locate the center point between the two bolt holes at the back of the toilet bowl.
• Place the end of your measuring tape on this center point.
• Extend the tape measure straight out to the front rim of the toilet bowl.

Bowl Width

This is the widest measurement of the toilet bowl, typically taken at the outer rim. It ensures the new seat doesn't overlap the bowl or leave gaps on either side. Getting this measurement wrong could lead to improper alignment and poor fit. It’s a good idea to seek help from a professional plumbing repair service if you have any doubts regarding bowl width.

How to Measure Bowl Width

• Identify the widest part of the toilet bowl. This is typically the middle section of the bowl.
• Place the measuring tape across the bowl at its widest point.
• Ensure the measuring tape or ruler is straight and level for an accurate measurement.
• Write down the width measurement for reference when purchasing a new toilet seat.

Seat Height

While not essential for functionality, some users consider seat height for comfort, especially for children or those with mobility limitations. This measurement is typically taken from the floor to the top of the toilet seat.

How to Measure Seat Height

• Close the toilet lid if present.
• Place the end of your measuring tape on the floor directly beneath the toilet seat.
• Extend the tape measure straight up to the top surface of the closed seat.
• Ensure the tape is straight and not angled to get an accurate reading.
• Record the measurement.
