Once you have zeroed down on the design, the next step is to measure the size of wallpaper you would require to cover up your walls in an aesthetic way.
In order to measure your wallpaper, you have to consider what you require:
Width – Measure the horizontal distance of the wall, from corner to corner.
Height – Measure the vertical height at each corner of the wall. Some walls are not perfectly square. If there is a difference in height, always select the greater of the two height measurements.
Make registration marks along the area that you want to cover.
Most wallpaper designs are pretty flexible and trimming the edges to achieve a perfect finish does not harm the overall look. Always use a measuring tape to get the most accurate measurement. Finally, add a few extra inches along the sides of your wallpaper. This will give you a little breathing space in case of any odd mistakes!
