How to Calculate Wallpaper with Repeat
Tools Needed for Accurate Measurement
To start, gather a high-quality tape measure, a level, a pencil, paper, and a digital device. Optionally, a laser measure can improve accuracy.
Measuring Wall Dimensions
Measure the height and width of each wall using inches for your calculations. For rooms with patterned wallpapers, taking precise measurements is critical to account for repeats in the design.
Calculating Wallpaper Repeat
Determine the vertical wallpaper repeat which is essential to align the patterns correctly. Measure the repeat in inches. This figure is pivotal in calculating the adjusted wall area required.
Formulas for Calculation
Use the formula Adjusted Height = Wall Height / Wallpaper Repeat to find out how many times the pattern repeats vertically. Round up any fractions to determine the wallpaper length required per strip.
For the wall's width, use the formula Adjusted Width = Wall Width / Wallpaper Width, rounding up fractions to find the number of strips needed.
Estimating Total Wallpaper Requirement
Add the total number of strips across all walls using the formula Total Strips = Adjusted Width * Number of Walls. Multiply the length of a wallpaper strip by the total number of strips (Total Area = Strip Length * Total Strips) to get the total wallpaper needed in feet. Then, convert to yards if necessary, again rounding up any fractions.
Additional Considerations
Always order extra wallpaper to allow for matching the repeat pattern and covering any potential waste due to cutting or mistakes.
Purchase all wallpaper from the same batch in one order to ensure color consistency throughout your room.
How to Calculate Wallpaper with Repeat
Calculating the amount of wallpaper needed for rooms with repeat patterns ensures accuracy and minimizes waste. This guide provides a succinct method to help you determine the precise quantity of wallpaper required.
Understanding Wallpaper Calculations
When calculating wallpaper for repeat patterns, it's essential to account for the entire room's dimensions and the wallpaper's specific repeat pattern. A wallpaper calculator simplifies this process by considering room dimensions, window and door spaces, and the repeat pattern of the wallpaper.
Steps to Calculate Wallpaper with Repeat
To begin, measure the height and width of each wall in inches, excluding trim, windows, and doors. Use the formula (Height of Wall / Height of Repeat) x Height of Repeat to calculate the length of each wallpaper strip. Remember to round up any fraction to ensure complete coverage.
Next, establish the number of strips needed by dividing the wall width by the wallpaper width using Wall Width / Wallpaper Width. Multiply the length of each strip by the total number of strips to find the total length of wallpaper required. Divide this by 12 to convert it into feet.
Add 10% extra wallpaper to the total to cover mistakes and potential repairs. This extra precaution helps in maintaining uniformity, especially with patterned designs, as indicated by specialists. If you have walls of different heights, are decorating a staircase, or have a complex room layout, consulting a professional is advisable.
Final Calculation and Ordering
Lastly, apply the formula Total Wallpaper Needed = (Length of Strip Needed) x (Number of Strips Needed). This final step assures that you purchase an adequate amount of wallpaper, considering all factors such as pattern repeats and extra for unforeseen issues.
Always order all the wallpaper you need in one go to ensure color consistency throughout the room. Consult your decorator before making a purchase to confirm the calculations are correct.
Conclusion
Calculating the appropriate amount of wallpaper with repeat patterns requires careful measurement and consideration of the room and wallpaper specifics. Using a wallpaper calculator and consulting with professionals when necessary will yield best results, reducing excess and ensuring a seamless wallpaper application.

Calculating Wallpaper with Pattern Repeat
Example 1: Standard Room
Determine the total square footage of the walls in a room measuring 12 feet by 8 feet with a ceiling height of 9 feet. Calculate the total wall area by multiplying the perimeter of the room (12+12+8+8) feet by the ceiling height (9) feet. Subtract the area of doors and windows. If the wallpaper has a repeat of 24 inches, factor this into the amount needed by adding an extra wallpaper length per every wall width to accommodate the repeat pattern.
Example 2: Large Windows
In a room of the same size but with larger windows, recalculate the total wall area, now subtracting a larger portion for windows. Choose wallcoverings that match the window's dominant color to minimize waste. For wallpaper with a 30-inch pattern repeat, adjust the quantity by adding half a length more for each wall segment, ensuring pattern continuity and alignment.
Example 3: Complex Wall Shapes
For rooms with irregular wall shapes or features like fireplaces, carefully measure each wall segment. Calculate the wallpaper required by considering each segment's height and adding extra lengths based on the 27-inch pattern repeat to allow for matching and cutting waste.
Example 4: Sloped Ceilings
In rooms with sloped ceilings, calculate the wall area differently. Treat each slope as a separate area, adding the extra repeats needed to align the wallpaper patterns across the different slopes, calculated proportionally based on the pattern repeat of 18 inches.
Example 5: Matching Multiple Rooms
When calculating wallpaper for multiple rooms with the same wallpaper, consider the entire house as one project. Calculate the total area, then add extra rolls to match patterns between rooms, especially for large pattern repeats, such as 36 inches, ensuring consistency and flow throughout the house.

Frequently Asked Questions
How do you calculate the amount of wallpaper needed for a room with a pattern repeat?
To calculate the amount of wallpaper needed with a pattern repeat, first measure the height and width of each wall in inches. Then, measure the vertical wallpaper repeat and the width of the wallpaper. Calculate the number of repeats needed per wall by dividing the wall height by the wallpaper repeat and rounding up any fractions. Multiply this by the wallpaper repeat height to get the length of each strip. Determine the number of strips per wall by dividing the wall width by the wallpaper width. Add the strips from all walls for the total number of strips needed across the room. Multiply the length of each strip by the total number of strips to get the total wallpaper needed in feet.
What measurements are necessary to estimate wallpaper with repeat patterns?
To estimate wallpaper with repeat patterns, you must measure the height and width of each wall, as well as the vertical repeat and width of the wallpaper. If you order by the roll, you also need to know the roll length.
How do you handle doors and windows when measuring for wallpaper with a repeat?
When measuring for wallpaper with a repeat, doors, windows, and other obstacles should generally be ignored unless they stretch from ceiling to floor. This practice allows for a bit of extra wallpaper to account for mistakes and adjustments during the installation process.
What should be done if the pattern repeat is a drop match?
If the pattern repeat is a drop match or half drop, divide the pattern repeat by two to correctly adjust the calculations. Then, use the adjusted repeat height to determine how many drops (vertical strips required for the full wall height) are needed by dividing the total wall height by the adjusted pattern repeat and rounding up the result.
How do you determine the number of rolls needed for wallpaper with repeat patterns?
To determine the number of rolls needed for wallpaper with repeat patterns, calculate the number of strips needed to cover each wall by dividing the wall width by the wallpaper's width and rounding up. Calculate the total number of strips needed for all walls combined. If you know the roll length and whether the wallpaper comes in a double roll, divide the total number of strips needed by the number of strips per roll (determined by dividing the roll length by the wallpaper's length per strip). Round up to ensure you have enough for the entire room, and consider ordering extra for repairs and mistakes.
Conclusion
Mastering how to calculate wallpaper with repeat doesn't have to be complicated. By understanding the necessary calculations, such as adding extra length for each strip to match the pattern repeat, you can efficiently determine how much wallpaper you need. Utilize L + (R - (L % R)) where L is the length of your wall and R is the repeat length, for seamless designs.
