Have you ever fallen head over heels for a wallpaper design, only to get completely stumped when asked: “How many rolls do you need?”
Don’t worry—you’re not alone. Measuring your space and figuring out how much wallpaper to buy might sound like a math class you didn’t sign up for, but with a little guidance and the right tools (hello, wallpaper calculator!), it becomes surprisingly simple—and even empowering.
Therefore in this guide, we’re breaking down everything you need to know about calculating wallpaper rolls, avoiding costly mistakes, and transforming your walls with confidence.
Whether you’re a first-time decorator or an old pro dabbling in custom prints, this is your go-to resource.
Why Accurate Measurement Matters
Before you even begin browsing designs, one thing is crucial—measure your wall right. Exact wall measurements not only help in ordering the right quantity of wallpaper but also prevent waste, extra costs, and installation delays. At Magicdecor, we always recommend adding an inch on all four sides to account for uneven wall surfaces and human error—because perfection lies in preparation.
The Rule of Thumb:
Measure the width and height of your wall. Multiply them to get the total area in square feet or meters. Then divide that by the area one wallpaper roll covers (Magicdecor rolls cover approx. 38 sq. ft.) to know how many rolls you’ll need.
Case-by-Case Measuring Tips
Walls are rarely perfect rectangles, and that’s where most miscalculations happen. Here’s how to measure in real-world scenarios:
1. Standard Walls
This one’s straightforward. Measure width and height. Double-check both. And you are good to go ahead and place an order. But is it that simple as it sounds? No but when we are here, you need not feel this as a task. At Magicdecor, we add 1 inch extra on all four sides before printing.
2. Sloped Walls
Sloped walls, commonly found in attic spaces or under staircases, may look tricky to wallpaper—but the measuring process is simpler than it seems.
How to measure: Instead of trying to calculate the angled portion, just measure the maximum height and maximum width of the wall—right from the tallest point to the widest horizontal stretch
Why this works: At Magicdecor, we print your wallpaper as a full rectangle. The sloped or angled portion is trimmed on-site during installation. This approach avoids misalignment, ensures the pattern flows seamlessly, and offers extra margin to correct minor cutting errors during application.
3. Multi-Sloped Walls
These are walls with more than one slope—like triangular dormer walls or a zigzag roofline in loft-style homes.
How to measure: Find the highest vertical point of the entire structure and the widest horizontal span across all slopes. Measure these two points as if you’re drawing a big invisible box around the wall.
Installation tip: The wallpaper will be printed as a large rectangle to cover the entire area. During installation, the extra portions are carefully trimmed to fit the multi-angled shape. Don’t worry—our expert installers (or your toolkit if you’re DIY-ing) will make it a breeze.
4. Walls with Doors & Windows
Walls with cut-outs—like windows, doors, or built-in cabinets—are more common than we think. You might wonder if you should subtract these from your measurement.
The answer? Don’t. Measure the entire wall from one end to the other, including the doors and windows.
Why? Because wallpaper needs to maintain design continuity. By measuring the full surface, you ensure the mural or pattern remains uninterrupted. The installer will then trim out the exact shapes of windows and doors during application, giving you a crisp, tailored finish around them.
5. Multiple Walls
If your living room has an L-shaped layout or you’re wallpapering two or three adjacent walls, the process is still easy.
How to measure: Add the widths of all the walls together to get the total width. Use the tallest height among those walls as the standard height for all.
Design consistency: This method ensures the wallpaper flows smoothly from one wall to another, keeping patterns aligned and symmetrical. You won’t have to worry about mismatched designs or visible breaks between panels.
6. Staircase Walls
Walls along staircases often have dramatic, slanted angles, making them unique canvases for wallpaper—but also tricky to measure.
How to measure: Stand back and visually frame the wall from its lowest point (usually near the base of the stairs) to the highest point (at the top of the incline). Then, measure the full width at its widest point.
Installation insight: Like other sloped spaces, your wallpaper will be printed as a large rectangle. During installation, any excess (angled) portions are carefully removed. This ensures the print remains uninterrupted and the finished look appears custom-fit, not patched.
Using the Magicdecor Wallpaper Calculator
Now for the fun part—let tech do the math! Magicdecor’s easy wallpaper calculator asks for just two things:
- Width of your wall
- Height of your wall
And voila—it tells you:
- How much area you need to cover
- How many wallpaper rolls you’ll need
- Total estimated cost
This tool removes the guesswork and offers precise, real-time results that match your needs.
Pro Tips for Smart Wallpapering
✅ Always Round Up
Ordering 0.5 rolls short? Don’t risk it. Always round up to the nearest whole number to account for alignment errors or future patches.
✅ Add 10-15% Wastage for Patterns
If your wallpaper has large prints or geometric patterns that need to match up, you’ll need a little extra to align those motifs properly.
✅ Use a Steel Tape
Cotton tapes can stretch and mislead. A steel tape gives you the most accurate measurements.
Wallpaper Roll vs. Custom-Fit: Which is Better?
At Magicdecor, you have two options:
1. Wallpaper Rolls
These are pre-sized rolls covering approx. 38 sq. ft. each. Ideal for DIYers and budget buyers.
2. Custom Wallpapers
These are printed to your wall’s exact measurements. It eliminates pattern breaks, minimises waste, and gives a clean, seamless finish—perfect for designer homes and curated spaces.
Pro Insight: Custom-fit wallpapers reduce both time and cost over long-term use, especially in modern homes where wall dimensions can vary drastically.
Understanding Wallpaper Material Options
Your wallpaper’s success doesn’t just depend on how much you order—it also depends on what you order.
Magicdecor Offers:
- Textured Wallpapers: Hide wall flaws, add depth
- Non-woven Rolls: Durable and breathable
- Peel and Stick: Great for rented spaces
- Pet & Kid Friendly Wallpapers: VOC-free and washable
All come with a matte finish and a premium 250+ gsm thickness.

Step 2: Input Your Measurements
This is where the magic of precision begins. Measure the width and height of your wall using a steel tape for best accuracy (avoid fabric ones—they stretch!).
