Measuring your floors

Helping you estimate how much carpet you need

It's useful to have a rough estimate of your room measurements with you when you go shopping.

Here is a quick guide to help you with initial estimates. Your local retailer or qualified carpet installer will usually want to provide an exact measure before placing your order.

Measure length (1) x width (2)

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

This is important so the correct number of repeats or length can be calculated.

Measure any indentations (3 and 4)

If the room is not a regular shape, make sure to measure any indentations too, e.g. built-in robes 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!


  • This is only a guide - your local carpet expert will usually want to be able to see the space and measure for themselves to plan the most economical way to lay the carpet.
  • Patterned carpets - if you choose a patterned design you might need to order extra carpet to match this up across rooms or in unusual shapes.
  • Stairs with winders or half landings will need additional carpet to satisfy changes in pile direction.
  • Underlay and fitting costs need to be added in too.
  • Remember, your retailer will be able to help you with this.
