# How to calculate the number of tiles for different types of tiles surfaces

Tile calculation is very important for quantity surveyors. Tiles may come in different shapes like square, circular, elliptical etc. It is easy to make calculation for square shaped tiles. But the process becomes complicated for circular or elliptical shapes.

In the following construction video, the detailed process is given for making calculation for different types of tiles surfaces as well as locating number of tiles necessary for the surface of the structure.

The general formula for finding out the number of tiles is given below :-

No. of tiles = Area of surface / Area of Tile

Here area of surface can be determined by multiplying height and length of surface i.e. H x L

So, No. of tiles = H x L / S x S, here S denotes Surface area of tile.

This process will be most suitable for finding out the number of tiles with square shape.
