How to Measure Toilet Seat Sizes Correctly: A Step-by-Step Guide

Finding the right toilet seat might seem simple, but it requires knowing specific measurements for a perfect fit. To ensure your new toilet seat fits correctly, use a tape measure to determine the seat’s length, width and the toilet’s bolt spread. Most toilet models come in round or elongated shapes, so knowing this will prevent mismatches.

Measure from the centre of the two fixing holes to the front edge of the toilet seat. Check the width at its widest point too. Elongated seats typically measure about 18 inches in length, while round seats are around 16 inches.

Consider all the styles and materials available. Whether you prefer a classic plastic seat or one with soft-close hinges, there’s something for every bathroom. Remember, accurate measurements ensure your new seat is both comfortable and secure.

Types of Toilet Seats

Most toilet seats come in two main shapes: round and elongated. A round seat, often found in older homes or smaller bathrooms, measures about 16.5 inches in length. In contrast, elongated seats are around 18.5 inches, offering more surface area for comfort.

D-shaped and square toilet seats are other options, commonly seen in designer bathrooms. Apart from shapes, toilet seats vary in materials. Plastic seats are affordable and easy to clean, while wooden seats offer a warm, traditional look.

Importance of Correct Measurement

Measuring a toilet seat properly ensures you buy the correct size, avoiding unnecessary purchases or returns. You’ll need a tape measure to check three key dimensions: the length from the centre of the two mounting holes to the edge of the toilet bowl rim, the width at the widest point and the distance between fixing holes.

For a round or elongated seat, these measurements confirm a proper fit. Following the manufacturer’s instructions carefully guarantees the seat aligns with the bolt holes. This prevents any misalignment or instability, ensuring the seat fits securely and functions well with your toilet model.

 

Preparing to Measure a Toilet Seat

Before you begin measuring your toilet seat, it’s important to gather the necessary tools and identify the shape of your toilet seat. This ensures you get the correct measurements and find a replacement seat that fits perfectly.

 

Tools Required

To measure a toilet seat accurately, start with a reliable tape measure. It is the most crucial tool needed for this task. You might also require a paper and pencil to jot down measurements, ensuring you capture everything correctly.

Make sure the tape measure is flexible and marked in both inches and centimetres. This helps when you compare sizes, as some countries might use different units. A cleaning cloth can also be helpful to clear any dust or dirt from around the area you will measure.

Identifying the Seat Shape

Understanding your toilet seat shape is important. Toilet seats come in different shapes, such as round, elongated or D-shaped. Determining the shape starts by looking at the toilet bowl from the top view.

A round toilet seat has a more circular appearance, typically measuring around 16.5 inches in length. An elongated seat has a more oval look, measuring about 18.5 inches long. D-shaped seats, which are less common, combine elements of both round and elongated shapes with slightly angular sides.

 

Step-by-Step Measurement Guide

To select the right toilet seat, ensure you take accurate measurements. Follow these steps to measure the width, length and bolt spread of your toilet seat for the perfect fit.

1. Measuring the Width

Start by measuring the width of your toilet seat. Use a tape measure and extend it across the widest point of the seat. Typically, the width spans from one outer edge of the seat to the other. This dimension can vary, so it’s essential to have accurate measurements to ensure a snug fit.

Take note of the measurement in either centimetres or inches, according to your preference. This will help you choose a seat that matches your toilet’s dimensions, preventing any fitting issues.

 

2. Measuring the Length

Next, measure the length of the toilet seat. Position your tape measure between the two mounting holes or fixing holes at the back of the toilet bowl. Extend the tape measure straight down the centre line to the front edge of the bowl.

For round seats, you will generally find the length is around 16.5 inches (42 cm), while elongated seats may measure about 18.5 inches (47 cm). These slight variations in length make it necessary to check the size, ensuring the seat and bowl align correctly.

 

3. Measuring the Bolt Spread

Finally, measure the bolt spread. This refers to the distance between the two mounting holes at the back of the toilet. Typical toilets have a standard bolt spread of 5.5 inches (14 cm), though you should confirm this by measuring.

Use your tape measure to take this measurement, noting any significant differences that might require you to look for a specialty seat. Getting the correct bolt spread ensures your new toilet seat is sturdy and securely attached.

 

Choosing the Right Replacement Seat

Finding the right replacement toilet seat requires attention to the shape and features of your existing toilet. Matching the seat to the bowl shape ensures a proper fit, while considering seat features like material and hinge type can enhance comfort and functionality.

 

Matching Seat to Bowl Shape

To select the correct seat, first identify your toilet’s shape. Toilets generally come in round, elongated, or D-shaped designs. Use a tape measure to determine the longest part of the bowl from the centre of the two mounting holes to the front edge. 

Generally, a round toilet bowl measures approximately 16.5 inches, while an elongated toilet bowl is about 18.5 inches. Knowing these dimensions helps ensure the seat fits perfectly and avoids a second trip to the hardware store.

Another step is to check the width of the bowl at its widest point. This measurement helps confirm that the replacement seat will cover the bowl’s surface properly. Make sure to measure both the width and length to guarantee a successful fit.

 

Considering Seat Features

Selecting the appropriate seat to replace the existing seat also involves considering the toilet seat materials and features that cater to your needs. Plastic seats are lightweight and easy to clean, whereas wooden seats offer a more durable, traditional look. For added convenience, soft close toilet seats with slow-close hinges prevent slamming and potential damage or noise.

Some seats come with specialty features, such as seat warmers or raised seats, which can provide added comfort, particularly in colder months or for people with mobility issues. Matching these features with your preferences ensures that the new seat not only fits but also enhances your bathroom experience. Always read the manufacturer’s instructions carefully for proper installation and care of the new seat.
