As a homeowner, you may have wondered if toilet seats come in different sizes. You’re not alone – this is a common question that comes up when shopping for a new toilet seat.

Do Toilet Seats Have Different Sizes

As a homeowner, you need to make sure that you pick a toilet seat that is the right size.

How do you know what size toilet seat fits your toilet?

The answer is actually quite simple – all you need to do is measure the distance between the bolts that hold the seat in place.

Most toilets have standard measurements, so finding a seat that will fit shouldn’t be too difficult.

However, if you have an unusually sized toilet, you may need to look for a custom seat.

Or, you can simply measure the distance between the bolts and then find a seat that is close to that measurement.

With a little bit of trial and error, you should be able to find a toilet seat that fits your toilet perfectly.

How many different sizes of toilet seats are there?

Toilet seats come in a variety of sizes to accommodate different users.

The most common size is the standard size, which is typically 17 to 18 inches wide. This size will fit most toilets and will provide adequate support for the average user.

There are also oversized seats that can be up to 20 inches wide. These seats are often used in public restrooms or in homes where people have a larger than average build.

Also, there are child-sized seats that are around 12 inches wide. These seats are designed for children who are potty training or who are too small to use a standard-sized seat.

However, some people may need a larger or smaller seat to be comfortable. Toilet seats are available in a range of sizes, from extra small to extra-large.

Some companies also offer custom-sized toilet seats to ensure a perfect fit. With so many options available, there is sure to be a toilet seat that is just right for you.

Can you put a bigger toilet seat on a small toilet?

The answer depends on the size of your toilet and the size of the seat you want to put on it.

If the seat is too big, it might not fit comfortably on the toilet. If it’s too small, it could slip off easily.

You might be able to find a seat that’s just right, or you might have to get creative and makeshift something that works.

But in general, it’s probably best to stick with a seat that’s designed to fit your toilet.

That way, you can avoid any accidents and ensure that your seat will stay firmly in place.

Do all toilet seats have the same size hole?

Standard toilet seats have a hole that is approximately four inches in diameter.

However, there are a variety of other sizes available on the market.

For example, some seats have a smaller hole that is just three inches in diameter. Others have a larger hole that is five inches in diameter. There are even seats with an extra-large hole that is six inches in diameter.

So, the next time you are in the market for a new toilet seat, be sure to measure the hole to ensure that you get the right size.


Toilet seats come in a variety of different sizes to accommodate different users.

The most common size is the standard, which typically measures between 17 and 18 inches wide.

All you need to do is to find the one that fits the dimensions of your toilet. This is to ensure that the toilet seat is stable to prevent any unnecessary risks.

I hope you find this helpful.
