With their daily use, toilet seats are one bathroom item that will definitely need replacing over time. All toilet seats are not created the same, so you will need to measure and fit your new seat. It is not a complex task. When buying a new toilet, the seat specifications for that toilet may be included; however, if you are buying a replacement toilet or simply replacing the seat itself, you will need to measure and make sure that the seat you purchase is the right size.

Measure from the centre front of the toilet bowl, back to the middle of one of the hinge bolts that hold the present seat in place, using the tape measure. Match your measurement with the two seat sizes. Regular or round front toilet seats, common in many homes, are about 41.2 cm (16 1/2 inches) long. Elongated toilet seats, on the other hand, are about 46.3 cm (18 1/2 inches) long.
Measure the distance from the centre of one of the toilet seat hinge posts to the centre of the other hinge post. The standard distance between these hinge posts is about 13.8 cm (5 1/2 inches). Combine the two measurements to provide you with an accurate figure for buying a replacement toilet seat. Take the measurements along to a plumbing supplier or a home improvement shop to find the correct toilet seat size.
Open the bolt covers on the old toilet seat. Unscrew each seat bolt with a screwdriver, while holding the nut underneath with a spanner. Remove the old seat.
Place the new seat on the bowl, lining up the holes in the seat with the hinge post holes in the top of the bowl. Place the new bolts through both the seat holes and the hinge post holes. Thread a washer up each bolt, underneath the bowl. Fit a nut over each bolt. Tighten each bolt with a screwdriver while holding the nut underneath the bowl with a spanner. Snap the bolt covers closed.
