Measure tread (1) + riser (2)

The tread is the part you step on. Starting with the top step, measure the depth of the tread. Be sure to extend the tape measure all the way to the outer edge of the step. The riser/fall of the step refers to the height between one step and the next. E.g. 20cm + 20cm = 40cm

Add these two measurements together. You should add approximately 5cm per step to allow for covering edges or extra needed for underlay.

Count the number of steps!

Multiply your first number by the number of steps you have to cover: e.g. 20cm + 20cm = 40cm x 12 steps = 4.8m (This is your LENGTH)

Measure the width (3)

Measure the width of the steps to know how wide the piece of carpet must be. Again add 5cm for allowances (This is your WIDTH).

This is only a guide - We will usually want to be able to see the space and measure for ourselves to plan the most economical way to lay the carpet.

Measure width (1) x length (2)

Measure the maximum width and length at the room's widest points.

Measure any indentations (3 and 4)
If the room is not a regular shape, make sure to measure any indentations too, e.g. fireplace, bay window etc. This is important so that all of the carpet you buy can be utilised effectively, helping you minimise cost and waste.

Measure to the 'back' of the
door frame (5)

Remember to allow enough carpet to be fitted under the door threshold!

Multiply the width measurement by the length measurement to give you an idea of the total square metres required (carpet prices are usually per square metre), e.g. 2m x 4m = 8m².
