A standard roll of wallpaper in the US typically covers about 56 square feet, but the actual yardage can vary. Most rolls sold in North America are double rolls, meaning they contain twice the amount of paper found in a single roll historically. This translates to approximately 20.5 inches wide by 33 feet long per double roll. So, how many yards are in a roll of wallpaper? A common double roll is about 11 yards long (33 feet).
However, it’s crucial to understand that ‘double roll’ is a common convention, not a strict industry standard for yardage. Always check the specific dimensions listed by the manufacturer. Some rolls might be slightly wider or longer, impacting the total square footage and yardage available.
Understanding wallpaper dimensions and yardage
Wallpaper is sold by the roll, and its coverage is measured in square feet. A standard double roll in the US is generally 20.5 inches wide. When you multiply this width by the typical length of 33 feet, you get approximately 56.4 square feet of coverage per double roll. This includes a bit of extra for pattern matching and trimming.
To convert this to yards, remember that 1 yard equals 3 feet. So, a 33-foot roll is 11 yards long. Therefore, a typical double roll of wallpaper contains roughly 11 yards of length. But this is just the length; the total yardage also depends on the width.
Calculating wallpaper yardage for your project
When planning your wallpaper project, you need to calculate the total yardage required. This involves measuring your walls, accounting for doors and windows, and factoring in the wallpaper’s pattern repeat. A large pattern repeat means you’ll use more paper to align the design correctly across seams, thus reducing your usable yardage per roll.
To estimate, you’ll need the total square footage of the walls you plan to cover. Divide this by the square footage coverage of one roll (usually around 56 sq ft for a standard double roll). This gives you the number of double rolls you need. For example, if your room has 300 square feet of wall space, you’d need approximately 300 / 56 = 5.36 double rolls. Since you can’t buy parts of a roll, you’d round up to 6 double rolls.
If you’re working with a specific manufacturer, their product details will specify the dimensions. Always refer to these. For example, a roll might be listed as 20.5 inches x 33 feet, which confirms it’s a standard double roll with approximately 11 yards of length.
Common wallpaper roll sizes and their coverage
While the 20.5-inch width and 33-foot length (equating to about 11 yards) is common for double rolls in the US, other sizes exist. Some European wallpapers might come in single rolls, which are half the size of a double roll, typically around 20.5 inches wide by 16.5 feet long. This would be about 5.5 yards of length.
High-quality or specialty wallpapers, like those from Rifle Paper Co. or those featuring intricate floral designs, might have different dimensions or significantly larger pattern repeats. These factors can decrease the effective coverage per roll. Always check the product description carefully.
Key takeaway: A standard US double roll is approximately 20.5 inches wide and 33 feet long, totaling about 11 linear yards per roll. However, always verify the exact dimensions provided by the manufacturer.
The importance of pattern repeat
The pattern repeat is the vertical distance after which the wallpaper pattern repeats itself. It’s usually stated on the roll’s packaging or product description. A pattern repeat of 21 inches means that every 21 inches down the roll, the design starts over. Larger repeats consume more paper because you have to discard excess to align the pattern between strips.
For example, if a wallpaper has a 24-inch pattern repeat, and you’re hanging strips that are 8 feet long, you’ll lose a significant portion of the roll to achieve pattern matching. This reduction in usable material means you might need more rolls than a simple square footage calculation suggests. This is why it’s critical to use a wallpaper roll calculator that accounts for pattern repeat.
Calculating total yardage needed: formula and considerations
To calculate the total linear yards you need, start with your wall measurements. Measure the height of your walls and the total perimeter. Let’s say your room is 10 feet high and has a perimeter of 40 feet. This gives you 400 square feet of wall surface.
Now, consider a standard double roll of wallpaper, which is 20.5 inches wide (about 1.71 feet) and 33 feet long. The coverage is roughly 56.4 sq ft per roll. Divide the total wall square footage by the coverage per roll: 400 sq ft / 56.4 sq ft/roll ≈ 7.09 rolls. You would round up to 8 double rolls.
If the wallpaper has a large pattern repeat, you might need to add an extra roll. For instance, if the pattern repeat is 24 inches, you’ll need to account for the waste. Many online calculators factor this in automatically. When in doubt, it’s always better to have a little extra wallpaper than to run short. Unused, unopened rolls can often be returned.
What to do with leftover wallpaper
Having leftover wallpaper is not necessarily a bad thing. Small amounts can be used for touch-ups later on. Larger remnants might be perfect for smaller projects like lining drawers, covering a small accent box, or creating custom artwork. If you’re working with patterned wallpaper, remember that you might need to store remnants carefully to match future repairs.
If you’ve purchased a significant amount of extra wallpaper, check the retailer’s return policy. Many stores accept returns of unopened wallpaper rolls. It’s a good safety net to have a bit extra, especially with intricate patterns or if you’re concerned about color matching for future repairs. This is why understanding how many yards are in a roll of wallpaper from the start is so important.
Factors affecting wallpaper yardage requirements
Beyond the standard dimensions and pattern repeat, several other factors influence how much wallpaper you need:
- Wall irregularities: Uneven walls, alcoves, or complex architectural features can increase waste.
- Window and door placement: While you subtract the area of windows and doors, cutting around them can still lead to material loss.
- Wallpaper type: Some materials, like vinyl or textured wallpapers, might come in slightly different roll sizes or have specific installation requirements that affect yardage.
- Skill level: Less experienced DIYers might generate more waste due to mistakes or less efficient cutting.
Consider using resources like the calculator for how many rolls of wallpaper you need to get a more precise estimate. These tools are designed to help you avoid common pitfalls.
Choosing wallpaper for specific applications
When selecting wallpaper, think about its intended use. For high-moisture areas like bathrooms or kitchens, choose moisture-resistant or washable options. For a statement piece, consider bold patterns like those found in flowers on wallpaper collections or specific designer brands like Rifle Paper Co. wallpaper. These often come with specific yardage and pattern repeat information that must be adhered to.
For historical homes or unique aesthetics, you might look into antique wallpaper rolls, though these might have less standardized dimensions and require careful measurement and calculation.
Common mistakes to avoid when calculating yardage
The most common mistake is underestimating the amount of wallpaper needed. This often stems from not accounting for pattern repeat or simply assuming all rolls are the same size. Another error is not buying enough of the same dye lot. Wallpaper is printed in batches, and slight color variations can occur between different batches (dye lots). If you run out and have to buy another roll later, it might not match perfectly.
Always check the dye lot number on the rolls and ensure they all match. If you need to buy more later, try to find rolls with the same dye lot. If that’s not possible, use the extra rolls for less visible areas or for future repairs, hoping the difference won’t be too noticeable.
When calculating how many yards are in a roll of wallpaper, remember that the linear yardage is just one piece of the puzzle. The width and pattern repeat are equally critical for accurate project planning.
