Free Wallpaper Calculator (with Pattern Repeat)

Enter your wall dimensions and the vertical repeat of your pattern in the calculator below. It handles the repeat math and tells you exactly how many rolls to order.

Not sure what a vertical repeat is? Find it in our Wallpaper Repeat Dimensions section on any product page. Most Pine + Feather Studio patterns use a 24-inch or 36-inch repeat.

Four steps to an accurate order

  • 1) Find your vertical repeat

    It's in the Wallpaper Repeat Dimensions section on any product page. Most of ours are 24″ or 36″.

  • 2) Measure your wall

    Use your tallest wall for the height. Use the full width for each wall, doors and windows included.

  • 3) Choose your roll

    12-foot rolls suit most rooms; 27-foot rolls reduce seams on tall or commercial walls.

  • 4) Read your result

    Roll count plus a 10% buffer, with the full math shown below the number.

Illustrated and explained

    Find your vertical repeat

    The vertical repeat is the distance from one point in the pattern to where that same point appears again down the roll. Every panel is cut to a full repeat so the pattern aligns at the seams, which is why the repeat changes how many rolls you need. Find yours in the Wallpaper Repeat Dimensions section on any product page; most of our patterns repeat every 24 or 36 inches.

    Measure the wall, not the wallpaper

    Height is your tallest wall, floor to ceiling. Width is the full run of each wall, measured straight across. Doors and windows stay in the measurement; the offcuts around them become your trimming and matching allowance.

Wallpaper math, answered:

How much wallpaper do I need?

It depends on three things: the height of your tallest wall, the total width of all walls being papered, and the vertical repeat of the pattern. The calculator above handles all three. As a rough rule of thumb, expect to need about 15 to 20 percent more material than the raw square footage of your walls, due to pattern matching waste.

What is a vertical repeat?

A vertical repeat is the height of one full cycle of a wallpaper pattern, measured from any point in the design to where that same point appears again going down the roll. Most patterned wallpapers have a vertical repeat between 12 and 36 inches.

Can I use this calculator for wallpapers from other brands?

Yes. Choose your brand's roll width from the Roll width menu (it's usually on the product listing or the back of a sample) and enter their roll length. Pine + Feather rolls trim to 24 inches wide, which is why that's the default.

Should I order all my wallpaper at the same time?

Yes. Wallpaper is often printed in dye lots, and even small color variations between batches can be visible on the same wall. Calculate your full project, add a buffer, and order it all at once.

Do I subtract doors and windows from my measurements?

No. Measure the full width of every wall as if the doors and windows were not there. The material that would have covered those openings becomes your allowance for trimming, pattern matching, and mistakes. Subtracting openings is the most common way people end up short.

What if my walls are different heights?

Use your tallest wall for the height measurement. Every panel in the room is cut to the same length so the pattern stays level all the way around; shorter walls simply produce slightly larger offcuts.

What roll sizes does Pine + Feather Studio use?

Our rolls trim to 24 inches wide and come in 12-foot and 27-foot lengths. The 27-foot length is available for PVC-Free Type II and Commercial Vinyl. These differ from the double rolls common in US retail, which is why the calculator defaults to our dimensions and lets you change them for other brands.
