Wallpaper Calculator

Because eyeballing it and praying to the wallpaper gods isn’t a strategy.

How this works...

Measure Twice, Order Once

Welcome

Welcome to the glamorous world of math, darling. Guessing is for scratch-off tickets — not luxury walls. Use our Wallpaper Calculator to measure like a pro, shop like a boss, and hang wallpaper without the panic attack.

Measure in Feet + Inches

Use feet + inches when measuring your walls. Our wallpapers are sold in those units, so you’ll get the most precise results this way.

Trim and Margin

Walls aren’t perfectly straight (no matter what your contractor swore). Always allow a few extra inches at the top and bottom so you can trim for a clean, luxe finish.

Pro Tip

Order a little extra — not because you can’t measure, but because patterns have trust issues.

Disclaimer

Please note: this calculator provides estimates only based on your dimensions. For the most accurate results, we recommend confirming measurements with your wallpaper installer before placing an order. The 94th Floor does not provide official yardage or square footage quotes — final responsibility for ordering the correct amount lies with the client.

Enter your measurements and wallpaper details below and the calculator will tell you the amount of wallpaper required.
