How to Measure Your Walls For Your Wallpaper

A simple guide to measuring your walls for wallpaper. Learn how to calculate width and height correctly so you order the right number of sheets and avoid gaps or mismatched panels.

How to Measure Your Walls for Wallpaper

Accurate measurements are one of the most important parts of a successful wallpaper project. Taking a few minutes to measure correctly helps ensure you order the right quantity of wallpaper and maintain proper pattern alignment throughout your installation.

To begin, measure the full width and height of each wall you plan to cover. In most cases, we recommend measuring the entire wall rather than subtracting windows, doors, or other obstacles. This allows you to trim around openings during installation and helps ensure you have enough material to maintain the pattern repeat.

Once you have your measurements, use our Wallpaper Calculator to determine how many wallpaper sheets you will need. Simply enter your wall width and height and the calculator will recommend the appropriate quantity based on our 24-inch-wide wallpaper panels.

Frequently Asked Questions

Should I subtract windows and doors from my measurements?

In most cases, no. We generally recommend measuring the entire wall and trimming around obstacles during installation. This helps prevent ordering too little wallpaper and maintains proper pattern alignment.

How do I measure multiple walls?

Measure the width and height of each wall separately. If the walls will be wallpapered with the same design, you can calculate the quantity needed for each wall and combine the totals.

What if my wall height falls between two sheet sizes?

Always round up to the next available sheet height. This provides extra material for trimming and ensures full wall coverage.

What if my wall is taller than 144 inches?

Please contact us before ordering. We can help determine the best solution for your specific project.

Do I need to account for pattern repeat?

Our wallpaper calculator is designed to simplify the process, but some designs have larger pattern repeats that may require additional material. If you're unsure, feel free to contact us for assistance.

Can I use the same measuring method for peel and stick and traditional wallpaper?

Yes. The measuring process is the same regardless of whether you choose peel and stick wallpaper or traditional unpasted wallpaper.
