These days, toilet seats come in standard sizes, but measuring your seat before buying a replacement is still wise. Start by measuring the seat from back to front. Buy a standard round seat if the length is around 16 in (41 cm). If it's around 18 in (46 cm) long, go with an elongated seat.

Although round and elongated are shapes, the shapes refer to the front-half of the seat. The difference of two inches is key.
While it was also found to make the droplets larger and more concentrated with bacteria, the broad consensus among scientists is that it's more hygienic to flush with the lid down.

Toilet seats are sold by shape (not by length).
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).
The invention includes a “flap adapted to extend down into the toiletbowl and to partially rest upon the water there-in, so that when the toilet is flushed, the engagement of the flap with the water will cause the entire cover to be passed out with the flushing.” Unfortunately, he doesn't mention at which end we are ...
“In general, a toilet will outlast the toilet seat several times over,” says Summer Little, owner of Atlanta interior design firm, Prescott Design. “You should expect to replace a toilet seat every five years or so, depending on usage.

Standard toilets measure approximately 650mm x 380mm x 816mm (depth x width x height). Make room for this, plus a few more millimetres of unobstructed space in front and on both sides of the toilet for ease of movement. Leave at least 700mm of space in front and 200mm on either side of the toilet.
