How much does one unit of textured wallpaper cover?

Lorie, from which website or store are you going to order? Different manufacturers make various sizes. How thoughtless of them not to give you all the specifics. Give more info and will be glad to investigate for you. Best wishes! ☺️

The posted apparently missed that. As Jewell Martin says. Different manufacturers make wallpaper in different sizes. Whether buying online or in a store all you need is the square footage of your area. The rolls will have the coverage on the label. It will be stated online in the description.

It should tell you how many square feet it covers. You use that to calculate how much wallpaper you need. Allow 10% for waste. If you have never hung it before, you may want to allow more. I would also recommend using glue for prepasted wallpaper. It makes the job so much easier.

Ask the vendor to calculate how much you need, since this is part of their job. Each roll/double roll has its own dimensions and is impacted by the design repeat/match. It is safer to over order from the same lot than risk being short due to miscalculations or cutting errors.

Since there is probably no horizontal match pattern on such paper, there will be almost no waste. If you give the height of your wall and the length of the wall you want to cover, your supplier should be able to tell you how many rolls you will need. Keep it mind, it is better to buy an extra roll...make sure every roll you buy has the same "LOT" number (this will make a big difference in color)...check and see if they allow returns.

Lorie, let’s go with: Don’t order this product from Amazon. 1. Measure each wall you want to paper. Height (in inches or feet) times the width (in the same measurement) equals the area of the space. 144 sq inches equals 1 sq foot. 9 sq ft equals 1 sq yard. The 10% wastage includes not only your errors, but some of the walls may not be completely square. So the waste covers one wall being an inch off one direction or the other. I’m going shopping on line now, just to see what I can find. 🤶🏻

Home Depot...Double roll covers 56 square feet. Hope this helps.
