Considering wallpaper instead of paint? Our handy worksheet and calculator will take the guesswork out of how many rolls you’ll need to tackle this DIY project.

• Getting started

  To accurately determine the number of wallpaper rolls needed to cover the walls in your room, you’ll need to record your measurements before heading in-store. This will also make the selection process much easier, since you’ll be able to choose a print with enough stock to cover your entire space.

• Common wallpaper mistakes to avoid

  • Not enough paste on the edges of wallpaper when seaming, or the wrong type of paste altogether

  • A high room temperature, which can cause paste to dry too quickly

  • Insufficient wall surface preparation such as not sealing or applying sizing

  • Streaks on the surface after application, usually from excess paste

  • Gaps between pieces if butting and seaming was not done carefully

  • Bubbling or blistering if wallpaper was not smoothed properly
