How to Choose the Right Size of Wallpaper for a Room?

Decorating with wallpaper is one of the most effective ways to transform any room, whether it’s a cozy bedroom, a stylish living room, or even a small bathroom. Among the many wallpaper options available today, embossed wallpaper has become especially popular. With its 3D textured effect, it adds depth, elegance, and a tactile dimension that paint simply cannot provide. But before you pick out your favorite design, there’s one important question to ask: How do you choose the right size of wallpaper for your room?

At Walloro, we specialize in high-quality wallcoverings, including embossed wallpaper rolls, and we want to make the process of selecting the right size simple, practical, and stress-free. In this guide, we’ll explain step-by-step how to measure, plan, and purchase wallpaper so you don’t end up with too much—or worse, not enough.

Why Size Matters in Wallpaper Selection

Choosing wallpaper isn’t just about the pattern or texture. The size and amount of wallpaper you buy will determine whether the installation goes smoothly or turns into a costly headache. Too little wallpaper means you’ll need to reorder, which can cause color variation if it comes from a different batch. Too much, on the other hand, wastes money and storage space.

This is especially true for embossed wallpaper for walls, since it often has larger repeats (the repeating design pattern) and needs more precise alignment than flat wallpaper. Getting the right size ensures a perfect finish and reduces the risk of mismatched seams.

Step 1: Measure Your Walls Correctly

To calculate how much wallpaper you need, you must first measure your walls:

1. Measure the width of each wall.

2. Measure the height of the wall, from floor to ceiling.

3. Multiply the width × height to get the total square footage of each wall.

4. Add up the total square footage of all walls in the room.

 For example: If your living room wall is 12 feet wide × 9 feet high, that wall equals 108 square feet.

At Walloro, we recommend adding at least 10–15% extra for trimming, pattern matching, and mistakes.

Step 2: Understand Wallpaper Roll Sizes

Wallpaper rolls are not one-size-fits-all. Standard dimensions vary depending on the brand and style. For example:

• Single Roll: About 20.5 inches wide × 16.5 feet long (28 sq ft coverage).

• Double Roll: About 20.5 inches wide × 33 feet long (56 sq ft coverage).

• European Roll: About 21 inches wide × 33 feet long (57 sq ft coverage).

When buying embossed wallpaper rolls, coverage can differ slightly because the texture makes them thicker, and the design repeats are often larger.

💡 At Walloro, we clearly list the roll size and coverage on every product page, so you’ll know exactly how much you need.

Step 3: Consider the Pattern Repeat

One of the most overlooked details in wallpaper sizing is the pattern repeat. This refers to the distance before a design repeats itself. For embossed wallpapers—especially those with 3D floral, geometric, or damask designs—the repeat can be anywhere from 10 to 25 inches.

The larger the repeat, the more extra wallpaper you’ll need for proper alignment.

For example:

• Straight Match: Every strip lines up at the same height (requires more precise cutting).

• Drop Match: The pattern shifts slightly from strip to strip (needs more extra paper).

• Random Match: No alignment necessary (uses the least extra paper).

At Walloro, we provide detailed repeat information with every design so customers can easily plan ahead.

Step 4: Factor in Room Features

Doors, windows, and built-in cabinets will reduce the amount of wallpaper needed. But don’t subtract too much—since it’s better to have slightly more than less.

For instance: A standard door (21 sq ft) or a window (15 sq ft) can be subtracted from your total wall measurement. But still, we recommend ordering at least one extra roll, especially for embossed vinyl wallpaper, because seams need careful alignment.

Step 5: Use a Wallpaper Calculator

Leading websites like Wayfair, Wallpaper Direct, and Home Depot all provide wallpaper calculators to help buyers estimate rolls. However, they often assume flat wallpaper and don’t take textured surfaces into account.

That’s why Walloro’s calculator is tailored for embossed wallpapers, factoring in repeat size and pattern alignment. This ensures our customers get more accurate estimates than with generic tools.

Why Choose Walloro for Embossed Wallpaper

When you search for “embossed wallpaper for walls” or “3D embossed wall coverings” online, you’ll find many retailers. But here’s why Walloro stands out:

• Premium Quality: Our embossed wallpapers are made with durable, washable, fade-resistant materials.

• Accurate Sizing Tools: We provide clear coverage guides and an easy-to-use calculator.

• Exclusive Designs: From modern geometric textures to classic damask patterns, our collections are carefully curated.

• Customer Support: Our team helps you choose the right size and design—something you won’t find on bulk-seller sites.

• Better Value: Unlike many competitors, Walloro ensures you get exactly what you need—no hidden costs, no low-quality imports.

Competitors like Wayfair and Wallpaper Direct may offer wide selections, but they often lack specialized embossed wallpaper expertise. At Walloro, embossed designs are our specialty, making us the go-to source for textured wallcoverings.

Tips for Avoiding Common Wallpaper Sizing Mistakes

1. Always round up—it’s better to have extra than run short.

2. Account for pattern repeat—especially with embossed or textured designs.

3. Order at once—to avoid color variation from different batches.

4. Check roll dimensions carefully before buying.

5. Ask for expert help—Walloro’s team can double-check your measurements.
