Wallpaper Coverage …. Not What They Lead You To Believe

For all those folk who think they can figure up how much wallpaper they need without first consulting a professional installer, and they try to calculate based on square footage, along with “calculators” found on vendor websites … Here is a good example of why square footage is NOT an accurate calculator.

Referencing yesterday’s post …. I’m not going to get into a whole lot of math re square footage. Let’s focus on the Strip Count method. Let’s just say that this accent wall required 12.3 strips. Effectively, that is 13 strips.

Due to the 11′ height of the wall and due to the length of the pattern repeat, each 33′ long double roll bolt yielded two strips.

After I used those two strips, I was left with a “tail end” that was about 8′ long. Since my wall height was 11′, here was nothing I could do with a strip 8′ long. So it went to the scrap pile.

The paper was about 2′ wide. 2′ wide x 8′ long = about 16 square feet of waste. Multiply that times the 13 strips it took to cross the wall, and you get 208 square feet of paper that is going right into the trash bin.

That’s roughly equivalent to FOUR DOUBLE ROLL BOLTS of wallpaper. Bought and paid for, but not available to put on your wall.

In real life, measuring is even more complicated than that.

In addition, the photo above shows the waste from today’s install of a 14 single roll breakfast room. The large roll lying on the floor, and the roll behind it, are tightly wound up and are both WAY bigger than the photo makes them appear… A whole lot of paper cut off and thrown away, in order to match the pattern.

So, folks, please let the professional measure, before you order your wallpaper. There are many, many factors to be considered, aside from raw square footage.

Waste Factor – For All The People Who Order Wallpaper Based on Square Footage

May 17, 2020

To come up with how much to buy, lot of people carefully measure and calculate the square footage of their room, and then divide that by the square footage on a bolt of wallpaper. WRONG!

This does not allow for the “waste factor.”

Wallpaper is not like paint. You can’t grind it up and put it in a bucket and spread every square inch onto your walls. You will lose some – often a lot – to waste.

In the photo above, I have only papered 1/4 of the room. Yet look at my discard pile – all this paper was cut off in order to match the pattern, or to go around a window or door, etc.

By the end of the day, this pile was a whole lot larger.

Really Long Pattern Repeat

November 23, 2019


This wallpaper pattern by Justina Blackeney has a really long pattern repeat – 45″. That means that any given design motif appears only about every four feet!

See photo, where I have rolled the paper out on my table.

Depending on the height of your walls, matching the pattern could result in a tremendous amount of waste. Indeed, I was cutting off and throwing away about 2′ of paper for every strip I put on the wall.

That’s why a strip count is a more accurate way to measure for how many rolls of paper you need, instead of going strictly by square footage.
