The great thing about measuring your toilet seat is that regardless of the specific shape, the method of measuring is the same. Start by locating the bolts and measuring the distance between them. The standard size is typically 5 ½ inches. The next measurement you will take is the width of the seat at its widest point. Then, find the middle between the two bolt holes and measure from there to the middle of the outside edge of the toilet. The standard measurement is 16 ½ inches for round seats and 18 ½ inches for elongated seats.
By having these measurements with you when you go shopping, you can be sure to find a seat that will properly fit your toilet. But there are many other things to consider besides getting the toilet seat size right. For one thing, toilets can be either one or two pieces or wall-mounted or wall-hung. There are also all kinds of cool toilet seat features nowadays, but sometimes, the entire toilet needs replacing, especially if it’s part of a bathroom remodel.
