Step one: Measure the length of the floor area you want to tile.

Step two: Then, measure the width of the floor area you want to tile.

Step three: Using our tile calculator, input these values, using metres as a metric. Our tile calculator will calculate the area for you and show you how many tiles you need overall. Factor in your windows, doors and other obstructions to make your final measurement more accurate.

If you already know the area of your walls – simply enter the measurements into the totals box

Top tip: Square and rectangular rooms are simple to measure – but L-shaped rooms can be a little trickier to work out. If your room is L shaped, start by roughly sketching out the shape of the floor. Then, split the sketch into two square/rectangular shapes and measure the width and length of each separate shape. Calculate the area of each shape, then, add the two areas together. This is the total area of your floor.
