•  We need the full width of the wall you want to decorate, if this includes a chimney breast or alcoves, you must include the returns/recess depth within this measurement.

• We also need the full height of the wall, measure from the skirting boards to the ceiling/coving or picture rail you are decorating up to.

• A small saving may be achieved by deducting the surface area of any fireplace/surround, this will be nominal

  Write down these measurements as:

  Wall Width =    / Wall Height = 

•  Measure the width and height of each wall within your room that you want to decorate, include your doors and windows within these measurements as if they were not there. 

• If you have patio doors / bi-fold doors etc, do not include these within your measurements. Just note if they have any wall space above or any recess surrounding them that you may want to apply wallpaper to.

  Write down these measurements as:

  Wall 1: Width =    Height = 

  Wall 2: Width =    Height = 

  Wall 3: Width =    Height = 

  Wall 4: Width =    Height =

• With the housing stock across the country varying in shape, size and layout this can often be a difficult space to calculate wallpaper for. You may have double story height walls, bulkheads and of course the angles to work with created by the staircase. 

• We have a little layout that may help you know where and what to measure. This information will help greatly and it’s not something any website calculator could work out for you, click here to download. 

A wallpaper that is labelled with no pattern repeat or a free match, you should expect to achieve 4 full lengths of decorating from a complete wallpaper roll.

Think of this as a coverage per roll of around 2.00m of wall width (6 feet, 6 inches approx).

A wallpaper that is labelled advising a pattern repeat or a match is required to obtain continuity of design, you should expect to achieve 3 full lengths of decorating from a complete wallpaper roll.

Think of this as a coverage per roll of around 1.50m of wall width (5 feet approx).

You will likely also have a long length left over (not quite a full wall height length) that may be useful in other areas of a room such as above or below windows and doors.

If the space you wish to decorate has already been decorated and you are able to count the number of lengths that are in place (or have been), this will allow you to make a quick calculation using the guidance above.

Any other floor-to-ceiling height than the range specified above will require more thought and therefore further calculation.
