Properly measuring your walls is essential to ensure you order the right amount of wallpaper. Follow these simple steps to get accurate measurements:
1. Gather Your Tools
Before starting, you’ll need the following:
- Measuring tape (preferably a steel one for accuracy)
- Pen and paper (or a notes app)
- Calculator
2. Measure the Height
- Measure the height of the wall from the floor to the ceiling.
- Take measurements at multiple points, especially if the ceiling is uneven.
- Use the tallest height as your final measurement to ensure complete coverage.
3. Measure the Width
- Measure the width of the wall from one end to the other.
- For irregular walls, measure the widest section.
4. Account for Doors and Windows
- Measure the height and width of any doors or windows on the wall.
- Subtract these areas from the total wall area to calculate the wallpaper you’ll actually need.
Tip: Add an extra 10–15% to account for pattern matching, trimming, and mistakes.
5. Calculate the Total Wall Area
Use this simple formula:Wall Area=Height×Width\text{Wall Area} = \text{Height} \times \text{Width}Wall Area=Height×Width
- Repeat for all walls you plan to wallpaper.
- Add up the areas of all walls for the total wallpaper required.
6. Consider Wallpaper Rolls
Check the dimensions of the wallpaper roll (usually provided on the product page). For example, if one roll covers 57 square feet, divide your total wall area by 57 to estimate how many rolls you’ll need.
Example Calculation:
- Wall height = 10 ft, Wall width = 12 ft
- Wall area = 10 ft × 12 ft = 120 square feet
- If each roll covers 57 square feet: Rolls needed=12057=2.1 (round up to 3 rolls)\text{Rolls needed} = \frac{120}{57} = 2.1 \, \text{(round up to 3 rolls)} Rolls needed=57120=2.1(round up to 3 rolls)
7. For Patterned Wallpapers
If you’re choosing wallpapers with repeating patterns, you’ll need extra material to align the design. Check the “pattern repeat” details provided for the wallpaper.
8. Additional Tips
- Always order an extra roll for safety, especially for repairs or future touch-ups.
- If you’re covering curved or angled walls, consult a professional for precise measurements.
- Use a wallpaper calculator tool for quick estimates if available.
