How to Measure a Room For Wallpaper


Whether you’re adding an accent wall or modernizing your whole home with wallpaper, accurately estimating how much to buy is key. This saves you time and money by avoiding having to order extra at the last minute.

Start by subtracting your doors and windows from the total wall area. From there, divide your wall widths by the wallpaper’s usable coverage (which will depend on the pattern):

Measure the Walls

Whether you want to put up an eye-catching accent wall or give your entire home a makeover, the right measurements will help ensure that you get the job done perfectly. Using a metal tape measure, write down the height and width of each wall, leaving out baseboards and crown molding.

Next, subtract the area of any doors and windows from your total measurement to calculate how much wallpaper you need. Alternatively, add up the total length of each wall and enter this into Graham & Brown’s easy wallpaper calculator found on each product page. This should give you an accurate estimate of how many rolls you require. We always recommend ordering an extra roll of wallpaper for waste in case of mistakes or miscalculations.

Measure the Ceiling

It is important to measure the height of every wall in the room, including any recesses or architectural features. This will help you calculate how much wallpaper is needed for the room.

Use a metal tape measure and record the measurement. Be sure to include any widths of doors and windows as this will affect the amount of wallpaper you need.

Once you have all the measurements of your walls, divide the total width of the walls by the width of the wallpaper roll (provided in the product specifications). Then add the height measurement to this number and multiply by the pattern repeat if applicable. This will give you the number of usable strips on each roll of wallpaper.

Measure the Floor

Wallpaper can add a stylish touch to any room. But, it’s essential that you measure your walls accurately so you don’t overspend. This way, you’ll get a seamless, professional finish.

Start at one end of the wall and extend your tape measure horizontally to the other side, ignoring slopes or coving. Write down this measurement, together with the width of the wall (also written down).

Next, calculate your total height in metres, subtracting the widths of any doors or windows. Multiply your height by the width of the wallpaper roll you wish to use (found in the product specifications) to obtain the number of ‘drops’ required. Adding pattern repeat will also change this figure, so make sure to include it.

Measure the Windows

While you’re measuring the height of your walls, remember to include the heights of any doors and windows. This will help you ensure you’ve ordered enough wallpaper for the room.

If you’re using a patterned wallpaper, don’t forget to factor in the pattern repeat as well. This should be listed in the product specification and will give you an idea of how many full drops of wallpaper are included on each roll.

Once you have all of your measurements, add them up together to get the total area of the wall space you need to cover with wallpaper. Then subtract the areas of any doors and windows. This will make sure you order the right amount of wallpaper and avoid any costly mistakes down the line.

Measure the Doors

When it comes to ordering wallpaper, you need to consider the width of your walls (excluding openings like windows and doors) and the wallpaper roll size. You may want to factor in about 5% extra material for waste.

Pro Tip: Using a metal tape measure is important to ensure you get accurate measurements. Be sure to have a pencil and paper handy to jot down your dimensions as you go.

Next, take the height measurement of your wall and write it down on your paper. Keep in mind that if you have a patterned wallpaper, you’ll need to consider the pattern repeat. This is the vertical distance between identical repeats and should be indicated on your product’s label or in its specifications if sold online.
