To hang 7 rolls of wallpaper, you will need 1 to 2 standard packets or tubs of wallpaper paste. The exact amount depends on the type of wallpaper and the packaging.
For most pastes, mix one sachet to seven parts water, which will cover approximately eight to ten rolls of wallpaper. For heavier wallpaper, you'll need a thicker paste to stop the paper from sliding down the wall.

Here's a more detailed breakdown: Labor Costs: Hourly rates can range from £15 to £35 per hour. A standard day rate for a decorator might be between £100 to £150. Some decorators charge per roll, which can range from £25 to £70 depending on the type of wallpaper and complexity.
To measure for wallpaper, find the total linear wall distance and multiply it by ceiling height to get the square footage. Divide this by the square footage of a single roll (usually 25–30 sq ft, but check the exact product) and add 10–15% extra for waste and pattern matching.
For a standard 10x10 room, you will need approximately 10 to 14 standard single rolls (or about 5 to 7 double rolls) of wallpaper, depending on your ceiling height, pattern repeats, and the number of doors and windows.
8 Common Wallpaper Mistakes (and How to Fix Them)
The average price of wallpaper ranges from $20 to $100 per roll, depending heavily on the material, design, and backing. Factoring in premium and specialty options, the total market spread generally lands between $25 and $500+ per roll.
Wallpaper in pale shades reflects more light, which helps a space feel open and airy. Soft whites, sandy beiges, pale greens, and muted pastels all work beautifully in smaller rooms. Designs that draw the eye upward—like subtle stripes, tall floral stems, or tree motifs—can create the illusion of height.
The average hourly rate for a professional decorator ranges from £20 to £40+, with higher costs for more experienced painters or specialist work. Fixed prices are often preferred for larger projects or those involving multiple rooms, as they provide greater transparency and allow homeowners to budget effectively.
Using too much wallpaper paste
In addition, the excess paste will make the wallpaper heavier, making it more difficult to hang. The wallpaper may also start to peel if there is too much paste used. If not enough paste is used, the seams will not adhere properly and the wallpaper may come loose.
Yes, wallpaper is not only in style, but it is considered a fundamental design element rather than a basic accent. Modern, easily removable, and highly tactile options allow you to choose from three major directions:
A single roll of wallpaper typically contains about 28 to 30 square feet, but because of waste and pattern matching, it provides about 21 to 27 usable square feet.
A common practice is to use a runny mix of wallpaper paste to size the walls. Most paste manufacturers will include instructions on their packaging regarding the correct proportions of powder and water to make a substitute 'sizing' solution. A good rule of thumb would be to use an extra 20-25% more water.
Pouring it into sinks or toilets can block drains and leave behind residue that harms aquatic life. Smaller amounts typically just need to be left out to dry before going in the bin, while biodegradable blends may be suitable for compost bins.
If you're doing a feature wall wallpaper, especially one with a large pattern, then it's usually important to start in the centre of the wall but this is why it's important to plan this before starting.
What Is the 3-4-5 Rule? Cavaliere's formula is straightforward. To her, a well-designed space should feature three patterns, four style influences, and five colors or textures. Together, these elements serve as the foundation for a creative, confidence-boosting design.
To make a room look bigger, use light, bright colors like crisp whites, soft beiges, or cool pastels (such as airy light blue or sage green). These shades have a high Light Reflective Value (LRV), meaning they reflect natural light and visually recede walls to make spaces feel open and airy.
CON: For restricted spaces only
For a long time, wallpapers earned the reputation of peeling off and leaving unsightly residue on the wall. It is for this reason that wallpapers were avoided in high traffic areas and high moisture places, such as in the kitchen, bathroom etc.
Wallpaper installation cost averages $600, with most homeowners spending between $325 to $825 for a standard room. Prices range from $3 to $8 per square foot, including both materials and labor. Factors like wallpaper type, wall condition, and prep work can affect your final price.
With so many wallcovering options to choose from, the best wallpaper brands are the ones that offer plenty of pattern options, have crisp designs, and will endure the wear-and-tear of daily life for years to come.
The easiest and most beginner-friendly wallpaper to install is peel-and-stick (self-adhesive) wallpaper. It acts like a giant sticker, eliminating the need for messy glues, pastes, or water. Many DIYers also highly recommend paste-the-wall (non-woven) wallpaper, which requires rolling adhesive directly onto the wall rather than the paper.
The top 2026 wallpaper trends feature a blend of tactile neutrals (like faux linen and concrete), heritage revival block prints, and immersive scenic murals. These styles transform walls into foundational art rather than just background accents.
These are the places you should never wallpaper if you want a low-maintenance home
For an entire room, start in an inconspicuous corner (like behind a door). For a feature wall or one with a dominant focal point (like a fireplace), start dead center. Always drop a plumb line or use a laser level to ensure your first strip goes up perfectly straight.
