What You'll Need Before You Start

Before you begin measuring, gather the following tools: a metal tape measure (preferably 25 feet long), a pencil and notepad, a calculator, a step ladder (for high walls), and a level. Having these items on hand will make the process smoother and more accurate.

It's also helpful to have a friend or family member assist you, especially for measuring tall walls or large rooms. Accurate measurements are crucial, so take your time and double-check each measurement.

• Metal tape measure (25 ft recommended)
• Pencil and notepad
• Calculator
• Step ladder
• Level

Step 1: Measure the Height and Width of Each Wall

Start by measuring the height of each wall from the floor to the ceiling. Measure in several places (left, center, right) because ceilings and floors are often uneven. Use the tallest measurement to ensure you have enough wallpaper to cover any dips or slopes.

Next, measure the width of each wall from corner to corner. For walls with windows or doors, measure the full width first, then measure the width of the openings separately. You'll subtract these later. Write down all measurements clearly, labeling each wall (e.g., 'North Wall', 'East Wall').

• Measure height at three points per wall and use the tallest
• Measure full width of each wall, including openings
• Record measurements with clear labels

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

For windows and doors, measure their height and width. Subtract the area of these openings from the total wall area to avoid ordering too much wallpaper. However, keep in mind that you may need extra wallpaper for matching patterns around these features.

Also measure any other obstacles like fireplaces, built-in shelves, or radiators. For these, it's best to measure the full wall area and then plan to trim the wallpaper around the obstacle during installation. This approach ensures you have enough material to work with.

• Subtract window and door areas from total wall area
• Measure obstacles separately and plan for trimming
• Order extra wallpaper for pattern matching around openings

Step 3: Calculate the Total Wall Area and Number of Rolls

To calculate the total wall area, multiply the height by the width for each wall, then add up all the wall areas. For example, a wall that is 8 feet high and 12 feet wide has an area of 96 square feet. Do this for every wall and sum them up.

Next, divide the total square footage by the coverage area of a single wallpaper roll (usually 25 to 30 square feet for standard rolls, but check the product label). Always round up to the nearest whole roll. Add an extra 10-15% for waste, pattern matching, and mistakes. For patterns with a large repeat, you may need 20% extra.

• Total wall area = sum of (height × width) for each wall
• Divide total area by roll coverage (check product label)
• Add 10-15% extra for waste and pattern matching (20% for large repeats)

Step 4: Consider Pattern Repeat and Wallpaper Type

Pattern repeat is the vertical distance between matching points in a wallpaper design. If you're using a wallpaper with a large repeat, like the intricate Wildflower Constellations XIX with border, you'll need more material to ensure the pattern aligns correctly from strip to strip.

Some wallpapers, such as the beautiful Beth - Bluebird, have a smaller repeat or are random match, which reduces waste. Always check the product specifications for pattern repeat information. If you're unsure, our customer service team can help you calculate the exact amount needed.

• Check pattern repeat on product label or description
• Large repeats require more wallpaper (add 20% extra)
• Random match or small repeat designs are more forgiving

Step 5: Double-Check and Order Your Wallpaper

Before ordering, double-check all measurements and calculations. It's better to have a little extra wallpaper than to run out mid-project. Many wallpapers come in dye lots, so ordering all rolls at once ensures color consistency.

For a timeless look, consider the Beth - Bluebird wallpaper, or for a more dramatic statement, the Wildflower Constellations XIX with border is a stunning choice.

• Order all rolls from the same dye lot
• Consider ordering one extra roll for future repairs
