Are toilet seats the same size?
The simple answer to the question “Are toilet seats a standard size?” is no. Unfortunately, toilet seats aren’t produced in a standard size, however, that doesn’t mean you can’t easily find a replacement for your own toilet. Like many things in the home, your toilet will suffer a fair degree of wear and tear over the course of its life.
It’s hardly surprising. After all, it’s something you use every day. And it’s your toilet seat that takes the brunt of this regular use. If you share your home with someone of the opposite sex or children, you probably won’t appreciate how many times your toilet seat is raised and lowered over the course of a year.
However, if you think of it as around 4 times a day, that’s over 1,400 times your hinges will be put to work over the course of a year. So it’s not a surprise that “are toilet seats a standard size?” is one of the most popular toilet-based search terms on the internet.

How to Tell if Your Toilet Seat is Round or Elongated – I actually have a bit of trouble determining if a toilet seat is round or elongated. They look the same on a toilet bowl. Only when I see them displayed at a store do I see the difference clearly. You can determine the shape by measuring the distance from the back of the toilet bowl to its front edge. Here’s how you do it.
Lift up your toilet seatGet out your tape measurePlease the starting point (0 inches) in the middle of the two bolts that hold the seatNow pull the measuring tape to the edge of the front of your toilet bowl
Toilet seats are sold by shape (not by length). If you need to replace or install a new seat, knowing which shape you have will be enough. No need to bring exact measurements with you. You should, however, get exact measurements if you have a custom or non-standard toilet. 
If the length is between 18-19.5 inches, you have an elongated toilet bowl seat. If the length is between 17-17.75 inches, you have a round toilet bowl seat. Notice also that the elongated bowl is shaped more like an oval (egg-shaped).
Do KOHLER toilet seats fit American Standard toilets?
Toilet seats are to toilets like tires are to cars. Goodyear, Firestone, Michelin, etc. each fit Ford, Chevrolet, Toyota, etc. Chruch, Olsonite and Bemis all fit Kohler, American Standard, Eljer normal-style toilets. Typically the brand of the seat is not the brand of the toilet.
Exceptions are some seats from Kohler and American Standard toilets which are branded Kohler or American Standard. These were probably sold with the original toilet and were private-labeled for them by OEMs such as Bemis. Hence, for example, if you are replacing a Church seat, it can be replaced with any brand available at the moment.
Toilet seat vocabulary:
- Rim or ring – The open seat.
- Cover – The lid/cover/top that closes over the rim.
- Bumpers: The spacers on the bottom of the rim and the cover.
- Hinges – The mechanical part that raises and lowers the rim and cover.
- Bolts – The threaded posts connecting the hinges to the toilet.
- Nuts – The nuts and washers that attach to the bolts.
- Bolt-spread – The distance between bolt holes on the toilet measured from center-to-center. Aka hinge-spread.
- A toilet seat is comprised of the rim for seating and the cover that closes over it. Mounting hardware (bolts & nuts) are included with the seat.
Normal seat: Here are the three criteria which distinguish a normal-style toilet seat:
- The seat hinges are 5-1/2″ apart from center-to-center.
- The hinges mount down vertically, not back horizontally.
- The shape of the front of the seat is curved; not angular, square or squared-off.
If a toilet seat is different from any one of these features, it is special, unique and proprietary. Sizes: Normal-style toilet seats come in two bowl length sizes: Round or elongated. Round is also called “regular” and “plain.”* Elongated is also called “extended.” Some consumers say “oblong.” Although round and elongated are shapes, the shapes refer to the front-half of the seat. 
Dimensions: The widths of seats are not made in dimensional choices. Though there may be some fractional variance between wood vs. plastic or different brands and models. Materials: Toilet seats are made primarily of two material types:
- Enameled wood.
- Solid plastic.
Enameled wood is a composition of tiny wood shavings (almost saw dust) which are mixed with resin and compression-molded to form a solid material. The “wood” is then enamel painted. Since around 2000, MDF, Medium Density Fiberboard, has also been used to make “wood” seats.
Which is better round or elongated toilet seat?
June 6, 2021 
Round front or elongated bowl? Does it matter? The toilet is one of those fixtures in your home that you take for granted. You don’t always think about the specifics until you need a new one, or you need to do some maintenance. So, round or elongated; does it matter? Let’s go through it! The ‘what’ – what is the difference between round front and elongated? The ‘why’ – why do you care? Pro’s and Cons – Elongated bowl Pro’s and Con’s – Round front bowl The ‘What’ – as in – what’s the difference? One of the most basic things to understand about your toilet is if it features a ’round front’ or ‘elongated’ bowl. A round front bowl generally has a dimension of approximately 16.5″ from the seat bolt holes to the tip of the bowl. An elongated bowl is approximately 2″ longer, or about 18.5″. (Note: these dimensions can change from manufacturer to manufacturer, but there is almost always about a 2″ difference between the 2 sizes). The Why, as in.why would you care? When indoor toilets were first introduced, they were all designed with ’round front’ bowls – one size fits all. As more research was done, elongated bowls were added to the mix. There used to be a significant cost difference between the two choices, but that really isn’t the case any more.
- So, choices are largely decided by personal preference and available space,
- So, which should you buy? Let’s look at some Pro’s and Con’s for both: Pros and Cons Elongated Bowls: Pros: Elongated bowls are generally considered to be more attractive and comfortable than round front bowls, but as with most things, this is a matter of taste and can be affected by an individual’s height and weight.
Elongated bowls are also considered more ‘hygienic’ in that the larger surface area of the bowl makes is easier for men and children to use with less mess. The longer bowl size is also a requirement for ADA use, and the longer/wider bowl is generally easier to use for those with mobility issues.
