Wall Tile Calculator

For walls, the same principles apply, except that instead of measuring with all length, you have to input the height of the wall. When estimating the area it is worthwhile measuring the total number of windows and doors or any large fixtures separately. Then, run a calculation for each of those spaces, which can then be subtracted from the total area (and number of tiles), to get your estimation.

For example, measure each window or door, and make a note of the dimensions of each surface. Place those into the calculator, and put those results aside. Once you have measured all of the areas that would not require tiles, put the total area space into the calculator, and then subtract the results of each window or door from the total area.

Importance of Having Extra Tiles

It's always good to have some extra tiles for when mishaps occur. Whilst you might not need boxes and boxes, the difficulties of finding a tile many years down the line when there is a breakage want some chipping that you want to fix, without spare tiles in stock you will potentially struggle to find a matching replacement for the job.

Managing Wastage in Tiling

It's always wise to factor in some wastage for added cover. Tiles break during transportation and installation, and of course there is the cutting of tiles which does not always go to plan either. The industry standard recommend purchasing approximately 10 to 15% extra to account for these issues and maintain some stock for the future.
