In this detailed guide, we’ll walk you through how to measure for peel and stick wallpaper, offering expert tips and best practices to guarantee success.

Learn how to measure for peel and stick wallpaper with this step-by-step guide. Ensure a perfect fit and seamless installation with expert tips on accurate measuring.

Why Accurate Measurements Matter

Whether you’re wallpapering an accent wall or an entire room, accurate measurements are essential. Incorrect measurements can result in too little wallpaper, leaving you short mid-project, or purchasing too much, which leads to wasted materials and costs. Proper measurements help you:

• Avoid Surprises: Having too little or too much wallpaper can cause delays and extra expenses.
• Save Money: Accurate measurements ensure you buy just the right amount of wallpaper for your space.
• Achieve a Seamless Look: Correct measurements help you align patterns and avoid mismatched seams.

Tools You’ll Need to Measure for Peel and Stick Wallpaper

Before starting the measuring process, gather these essential tools to ensure accuracy:

• Measuring tape

• Pencil and notepad

• Calculator

• Ladder (for measuring taller walls)

• Level (optional, for verifying straight lines)

Tip: A flexible measuring tape works best, as it can easily bend around corners and reach into tight spaces.

Step 1: Measure the Height and Width of Your Wall

The first step is to measure the height and width of each wall where you plan to install peel and stick wallpaper. Here’s how to do it:

1. Measure the Width

Using your measuring tape, measure the width of the wall from one end to the other. If the wall is divided by windows, doors, or other architectural features, measure the width of each section separately.

Tip: Round your measurements to the nearest inch to simplify calculations.

2. Measure the Height

Measure the height of the wall from the floor to the ceiling. Be sure to take multiple measurements at different points along the wall, as older homes may have walls that are slightly uneven.

3. Multiply the Measurements

To calculate the total area of the wall, multiply the height by the width. This gives you the square footage of the area that needs to be covered with wallpaper.

Example: If your wall is 10 feet wide and 8 feet high, the total area would be 80 square feet (10 x 8 = 80).

Step 2: Account for Doors, Windows, and Other Features

If your wall has doors, windows, or other features that won’t be covered by wallpaper, subtract these areas from your total square footage.

1. Measure the Dimensions of the Door or Window

Measure the width and height of any doors or windows, then multiply these measurements to calculate the square footage of each feature.

2. Subtract These Areas

Once you’ve calculated the square footage of the doors or windows, subtract this number from the total wall area.

Example: If your wall is 80 square feet but there’s a 10-square-foot window, your total wallpaper area would be 70 square feet (80 – 10 = 70).

Step 3: Add Extra for Pattern Matching

If your peel and stick wallpaper has a repeating pattern, you’ll need to add extra material to ensure the patterns line up correctly at the seams. This is especially important for larger patterns or geometric designs that require precise alignment.

1. Check the Pattern Repeat Information

Most wallpaper manufacturers provide the pattern repeat measurement on the packaging or product description. This number tells you how often the pattern repeats vertically and helps you calculate the extra wallpaper needed.

2. Add 10-15% More Wallpaper

To account for pattern matching, add an extra 10-15% to your total square footage. This will ensure you have enough material to align the patterns correctly, especially when cutting around windows or doors.

Step 4: Calculate the Number of Wallpaper Rolls Needed

Now that you have the total square footage, it’s time to calculate how many rolls of wallpaper you’ll need. Here’s how:

1. Check the Coverage Area Per Roll

Each roll of peel and stick wallpaper covers a specific area, which is usually listed on the packaging. This coverage area is typically measured in square feet.

2. Divide the Total Wall Area by the Coverage Area

Take your total square footage (including any extra for pattern matching) and divide it by the coverage area of one roll of wallpaper. This will give you the number of rolls you need to purchase.

Example: If your total wall area is 100 square feet and each roll covers 25 square feet, you’ll need 4 rolls of wallpaper (100 ÷ 25 = 4).

3. Round Up

Always round up to the nearest whole roll to ensure you have enough wallpaper. It’s better to have a little extra than to run out mid-project.

Step 5: Double-Check Your Measurements

Before you buy your wallpaper, double-check your measurements to ensure accuracy. This is especially important if you’re working with patterned wallpaper or if your walls have unusual shapes or angles.

Expert Tips for Measuring Irregular Walls

Some walls are not straightforward and may have unique shapes or obstacles. Here’s how to handle measuring tricky spaces.

1. Measuring Sloped Walls

For walls with sloped ceilings, divide the wall into rectangular sections and measure each section separately. Calculate the square footage of each section and then add them together.

2. Measuring Walls with Nooks or Alcoves

Measure the height and width of each nook or alcove separately, then calculate the area just as you would for a regular wall. Be sure to subtract any doors or windows from your final total.

3. Handling Rounded Walls

For curved walls, use a flexible measuring tape to follow the curvature. Measure the height and width at multiple points along the curve and use the largest measurement to calculate the wallpaper needed.

Common Mistakes to Avoid When Measuring for Wallpaper

To ensure you get accurate measurements, avoid these common mistakes:

1. Rounding Down

Always round your measurements up rather than down. Rounding down can result in buying too little wallpaper, leading to mismatched patterns or unfinished sections.

2. Forgetting to Account for Pattern Repeats

Skipping the extra material needed for pattern matching can result in misaligned seams. Always check the pattern repeat and add extra square footage to your calculations.

3. Not Measuring Multiple Times

Walls may not always be perfectly straight, especially in older homes. Measure your wall in several places to ensure accuracy, particularly when it comes to height.

FAQs About Measuring for Peel and Stick Wallpaper

How do I calculate how much peel and stick wallpaper I need?

Measure the height and width of each wall to get the total square footage. Subtract the area of any doors or windows, and add extra square footage for pattern matching. Then divide the total by the coverage area of one roll of wallpaper.

Do I need to add extra wallpaper for pattern matching?

Yes, if your wallpaper has a repeating pattern, you should add 10-15% extra wallpaper to account for pattern alignment at the seams.

What’s the best way to measure a wall with a window?

Measure the height and width of the wall, then subtract the area of the window. Measure the window separately and subtract its square footage from the total wall area.

Conclusion

Learning how to measure for peel and stick wallpaper is a crucial step to ensure a smooth and successful installation. By following these steps—measuring accurately, accounting for windows and doors, and considering pattern repeats—you’ll have the right amount of wallpaper and avoid costly mistakes. With proper preparation, your wallpaper project will transform your space beautifully and efficiently.
