Planning a tiling project requires knowing exactly how many tiles you need, accounting for the area to be covered, the size of each tile, and a waste allowance for cuts and breakage. This tile calculator computes the number of tiles required for a given floor or wall area based on your room dimensions and chosen tile size, including an adjustable waste percentage to account for cuts around edges, corners, and inevitable breakage. It helps you avoid both under-ordering (causing project delays) and significant over-ordering (wasting money), giving contractors and DIYers a realistic materials estimate. Simply enter your area dimensions and tile size to get an accurate tile count for your project.
