Toilet seats are a necessary part of modern bathrooms and come in a variety of styles and sizes. “So, how big are the different types of toilet seats?”
Toilet Seat Sizes
1、Standard Toilet Seat
The standard toilet seat is probably the most well known toilet seat, as it is usually made out of either plastic or wood and is installed to the toilet with hinges. The dimensions are typically approximately 14 to 16 inches wide (or around 36 to 41 cm) and 16 to 18 inches long (or around 41 to 46 cm). These dimensions can be applied towards all kinds of household applications.

2、Smart Toilet Seat
As technology has advanced, smart toilets have always been produced with STATE-OF-THE-ART performance. Smart toilets, or toilet seats, are essentially smart equipment with a variety of options such as heated seats, bidets, or toilet cleaning. The dimensions of smart toilet seats are about the same as standard toilet seats, usually 14 to 16 inches wide and 16 to 18 inches long.
3、Soft-Close Toilet Seat
Soft-close toilet seats have a special buffer that slowly, and quietly, closes slowly to prevent loud noises which are caused by slamming or fast-closing conventional toilet seats. The dimensions of soft-close toilet seats can be interchanged with dimensions of standard toilet seats.

4、Kid’s Toilet Seat
Kid’s toilet seats are relatively simplistic in nature, as these are designed for a young child, which adds to the complexity of dimensions as kid’s toilet seats are smaller than an adult toilet seat. To explain a kid’s toilet seat, depending on the age of the child or children, and/or sizes, will predict the difference in dimensions. The dimensions for a kid’s toilet seat are normally as follows: 11 to 13 inches wide (around 28 to 33 cm) and 14 to 17 inches long (around 36 to 43 cm).
- Extended Toilet Seats
Extended toilet seats, as their name suggests, give a longer seated surface area for people who are typically taller, as well as others with special needs like expectant mothers or elderly individuals. They are longer than the traditional toilet seat, so there is more opportunity for comfort, e.g. leg space. The extended toilet seat is usually between 18 to 19 inches (about 46 to 48 cm) in length.

- Dual-Flush Toilet Seats
Dual-flush toilet seats are designed with two independent seats that are used simultaneously by partners, and the seats will each have their own design and control functions for a more private, personalized experience. The dimension and size of dual-flush toilet seats are comparable to traditional toilet seats.
