A standard wallpaper roll size is commonly 20.5 inches wide by 33 feet long, which covers about 56 square feet. This is the most widely used size in the U.S. and is often referred to as a “double roll” because it is sold as one continuous roll but enough material is typically used to cover roughly two standard wall sections.

In metric terms, a common standard roll is about 52 cm wide by 10 meters long, though sizes can vary by manufacturer and country. In the UK and Europe, wallpaper rolls are often slightly wider or longer than U.S. rolls.

There are also other sizes you may encounter, such as:

• Single rolls: smaller quantities, often around 21 inches by 16.5 feet
• Extra-wide rolls: used for easier installation and fewer seams
• Murals or specialty rolls: custom sizes for feature walls

Because wallpaper patterns repeat, the actual coverage you get may be less than the roll’s total square footage. Pattern repeat, wall height, and waste for trimming all affect how many rolls you need.

If you’re buying wallpaper, always check the roll dimensions listed on the label rather than assuming every roll is the same. The safest approach is to measure your wall and compare it with the roll’s coverage before purchasing.

To figure out how many wallpaper rolls you need, calculate the total wall area and then divide by the coverage of one roll.

1. Measure the room Measure the length, width, and height of the room. Then find the total wall area: Perimeter × wall height = total wall area Perimeter = 2 × (length + width)

2. Subtract openings Subtract the area of doors and large windows if you want a more accurate estimate.

3. Check the roll coverage A standard wallpaper roll usually covers about 5.2 to 5.6 square meters, but this depends on the roll size and pattern repeat. Always check the label.

4. Account for pattern matching If the wallpaper has a large pattern repeat, you may need extra rolls because some material is wasted when matching the design. Add about 10% extra, or more for complex patterns.

Example: If your room perimeter is 20 meters and wall height is 2.4 meters: 20 × 2.4 = 48 square meters If one roll covers 5.3 square meters: 48 ÷ 5.3 = 9.1 rolls Round up to 10 rolls, and add extra if the pattern needs matching.

Best rule: Buy one extra roll if you’re unsure, since color batches can vary and it’s safer to have spare material.

Measure the wall’s width and height in feet or inches.

1. Measure width Use a tape measure to find the full width of the wall from one side to the other. If the wall has windows, doors, or built-ins, measure the total wall first before subtracting anything.

2. Measure height Measure from the floor to the ceiling, or to the point where the wallpaper will end. Take the height in several places because ceilings and floors are not always perfectly level. Use the tallest measurement.

3. Calculate wall area Multiply width × height to get square footage. If the wall has large openings like doors or windows, subtract their area only if they are significant.

4. Check wallpaper roll coverage Look at the wallpaper roll label for coverage. Rolls vary, but many standard rolls cover about 30–35 square feet after pattern matching waste is considered. Patterned wallpaper usually needs extra because designs must align.

5. Account for repeats and waste If the pattern repeat is large, you may need more rolls than the square footage suggests. Always add extra for cutting, matching, and mistakes.

6. Divide and round up Divide your total wall area by the usable coverage per roll, then round up to the next whole roll. It’s smart to buy one extra roll if the pattern is matched or the room has many corners.

Wallpaper is a type of decorative material used to cover walls, usually printed or patterned, and traditionally made from paper. Wallcovering is the broader term for any material designed to cover a wall, including wallpaper but also vinyl, fabric, grasscloth, cork, foil, and nonwoven materials.

The main differences are:

1. Material Wallpaper is often paper-based. Wallcoverings can be made from many different materials, including more durable and washable synthetic or textured options.

2. Durability Wallpaper is generally less durable than many wallcoverings. Wallcoverings are often designed to resist moisture, stains, scratches, and wear, making them better for kitchens, bathrooms, hotels, and high-traffic areas.

3. Function Wallpaper is mostly decorative. Wallcovering can be decorative too, but it may also serve practical purposes such as sound absorption, insulation, or hiding wall imperfections.

4. Installation and maintenance Traditional wallpaper can be more delicate to install and remove. Many modern wallcoverings are easier to clean, more resistant to damage, and sometimes peelable or repositionable.

5. Scope of the term All wallpaper is a wallcovering, but not all wallcoverings are wallpaper.

In simple terms, wallpaper is one specific kind of wallcovering, while wallcovering rolls is a general term for a wider range of wall surface materials sold in roll form.

Start by measuring the wall and buying enough rolls from the same batch number. Turn off power, remove wall plates, nails, and loose paint. Clean the wall, fill holes, sand smooth, and prime if the wall is new, patched, or very porous.

Check the wallpaper type. Pre-pasted wallpaper needs water activation; non-pasted wallpaper needs adhesive applied to the paper or the wall, depending on the product. Follow the manufacturer’s instructions exactly.

Use a plumb line or level to draw a straight vertical starting line near a corner, not directly in the corner. This is important because corners are often uneven. Cut strips with a little extra length at the top and bottom.

Apply the first strip carefully along the guide line, leaving a small overlap at the ceiling and baseboard. Smooth it from the center outward with a wallpaper brush or plastic smoother to remove air bubbles. Do not stretch the paper.

Match the next strip at the pattern edge, not overlapping unless the wallpaper specifically requires it. Butt the seams tightly together. Wipe away paste immediately with a damp sponge.

For outlets and switches, hang the strip over the opening, then cut an X and trim neatly after turning the power off. At corners, let the paper wrap slightly around, then start a new strip on the next wall for a cleaner finish.

Trim excess paper at the top and bottom with a sharp blade and straight edge. Keep blades changed often for clean cuts. Let the wallpaper dry slowly, with moderate temperature and no strong airflow.

Yes—many wallpaper rolls are both washable and durable, but it depends on the material and finish.

Vinyl wallpaper is usually the most washable and durable option. It can handle light cleaning with a damp cloth or sponge, and it resists stains, moisture, and general wear better than paper-based wallpaper. This makes it a good choice for kitchens, bathrooms, hallways, and children’s rooms.

Non-woven wallpaper is also fairly durable and often easier to clean than traditional paper wallpaper. It is breathable, less likely to tear during installation, and can last a long time if maintained properly. Some versions are wipeable, but not all are fully washable.

Traditional paper wallpaper is generally the least durable and least washable. It can be damaged by water, scrubbing, or strong cleaning products. It is better suited for low-traffic areas like bedrooms or formal spaces.

The durability of wallpaper also depends on installation and upkeep. A properly installed wallpaper roll on a smooth, dry wall will last much longer. Avoid soaking it, using abrasive cleaners, or exposing it to excessive humidity unless it is specifically made for those conditions.

To know for sure, always check the manufacturer’s cleaning instructions. Labels like “washable,” “scrubbable,” or “wipeable” indicate different levels of cleanability. “Washable” usually means gentle wiping, while “scrubbable” means it can withstand more frequent cleaning.

So, wallpaper rolls can be washable and durable, but the exact performance varies by type, quality, and where they are used.

Start by checking the wallpaper repeat, which is the distance before the pattern starts over. Measure the repeat on the label, then plan your first strip so the pattern will line up neatly across the wall.

When cutting each length, add extra at the top and bottom. Lay out the next strip next to the previous one on a table or floor so you can slide it up or down until the pattern matches. Do not cut all strips the same length blindly, because the pattern may shift from strip to strip.

Hanging sequence matters. Hang the first strip plumb and smooth it firmly. For the next strip, align the pattern at eye level first, then match the full length. If the pattern is slightly off near the ceiling or skirting, trim the excess after it is hung rather than forcing the top match.

Use a sharp knife, clean paste on the edges, and press seams together lightly so they do not overlap. For large designs, mark the “drop” on each strip so you know how far the pattern moves down each time. If the repeat is a half-drop or random match, read the label carefully and stagger the cuts accordingly.

For corners, windows, and doors, keep the pattern match on the most visible sections and allow small adjustments in less noticeable areas. Always buy extra wallpaper to cover waste from matching the design, especially with bold or large prints.
