How to Calculate Wallpaper Needs

To figure out how much wallpaper you'll need, make note of how large each roll is and the total square footage of the walls you want to cover, minus any openings such as windows and doors:
Number of Rolls Needed = Square Footage of Wall 1 + Square Footage of Wall 2 + Square Footage of Wall 3 + Square Footage of Wall 4 – Square Footage of Any Openings / Square Footage per Roll
How to Measure for Wallpaper
To measure for wallpaper, use a steel measuring tape to measure the height and width of each wall you want to cover, not including baseboards, moldings, and other areas you don’t want to cover.
If the wall has large openings, such as a door, window, or fireplace, also measure the height and width of those, then subtract their square footage from the wall's total square footage. You don't have to worry about subtracting small openings, such as outlets or light switches.
If you're going to hang paper with a pattern, you'll most likely need a bit extra to allow the pattern to align and to keep the wall from looking crooked. Add about 10% of the total square footage to your wallpaper needs.
Who to Hire to Hang Wallpaper
It can be worth it to hire a professional to hang wallpaper, as working with an experienced wallpaper installer can help you avoid buying too much (or too little) and ensure the finished project looks great.
Your best bet is to work with someone who specializes in installing wallpaper. If you can't find a local installer, another option is to hire a handyperson. Just make sure the handyperson has experience working with wallpaper.
