How to measure your wall for Wallpaper or a Wall Mural

Measuring your walls for wallpaper is a simple procedure, especially if there are no windows or doors. However if you are wanting to wallpaper walls with windows and doors then this is the article for you. You will need a Metal Tape Measure and Pen and Paper.

Standard Wall (no windows or doors)

You will be measuring the Height and Width of the Wall.

Measure the Height: Measure from the top of the skirting board to the ceiling if square set, otherwise to the bottom of your cornice.

It is best to measure in 2-3 different spots along the wall. Not all walls are perfectly straight.

Measure the Width: Measure the total width of the wall from corner to corner. If you are wanting to wallpaper multiple walls continue the process and list the walls ie 1/2/3 or A/B/C.

Wall with a Door or Window

Follow the measuring process of a Standard Wall.

Draw the layout of the wall including the position of door or window. Measure the outer edge of the door or window to the wall corner. Follow this process for left of the door or window to the wall corner and the right of the door or window to the wall corner.

Now measure the top of the door or window to the ceiling if square set or to the bottom of the cornice.

As a check measure, remember to also measure the outside of the door or window width and height.

Wall with Doors and Windows

Start with the measuring process of a Standard Wall.

Draw the layout of the wall including the position of doors and windows.

Working from either the left or right wall corner Measure the outer edge of each door and window to the next door or window outer edge. Working your way to the other side of the wall corner.

Now measure the top of each door and window to the ceiling if square set or to the bottom of the cornice.

As a check measure, remember to also measure the outside of each door and window width and height.

Wall with a Pitch or Slant

Draw the layout of the wall.

Measure the absolute highest point for the pitch height and the lowest point for the secondary height.

Measure the width of the wall from corner to corner. If there are any windows and doors, you will need to follow the measuring process as above as well.

This information is crucial for your Wallpaper Supplier when calculating rolls. Wallpaper by design is repeatable to cover your wall. However, a Wall Mural is like giant artwork and can now be custom printed to fit your wall.

For a Wall Mural you will only need to measure the Walls overall Height and Width. Remember a little more for trimming.

For Wallpaper Rolls you need to take into account wallpaper roll size and pattern repeat for matching. Online calculators are not accurate and do not consider offset pattern matching and alternating rolls.

These are tricks of the trade to minimise wastage. That is why it is important to consulate with your Interior Decorating Specialist.
