It’s possible to hang your own wallpaper, but the process is tedious and potentially frustrating, and it can be challenging to get seams to line up and look clean and professional. Plus, depending on the type of wallpaper you’re installing, using too much or too little adhesive could cause damage to your drywall or plaster, peeling, and bubbling in the final product. It’s usually a better idea to hire a professional wallpaper installer to do the work for you, as the relatively low cost is justifiable, if only to avoid damage to your walls.

There can be too much of a good thing when it comes to accent walls, so avoid creating one in every room in your house. Some rooms, like bathrooms and kitchens, don’t naturally lend themselves to accent walls, so it’s best to skip them there. Of course, your home should reflect your own sense of style, so if accent walls in multiple rooms appeal to you, there’s no hard-and-fast rule forbidding it.

The pros of wallpaper include its durability and longer lifespan than paint, as well as its versatility. The durability can translate to lower long-term costs for upkeep and replacement, and the versatility means you have more options for customizing rooms in your home. Some downsides include that it’s difficult to remove, it’s not ideal for rooms or areas exposed to high moisture content or sun exposure, and it’s tricky to install. A professional wallpaper hanger can help mitigate these issues, though, by installing it properly and in areas suitable for wallpaper.

To determine how many rolls of peel-and-stick wallpaper you need, measure the square footage of the walls you’re covering and divide that by the square footage that each roll covers. Add 10% to 20% of your total square footage to account for pattern matching or damage while installing.
