How Much Wallpaper Do I Need? Use Our Calculator to Find Out

One of the most common questions we hear is simple: How much wallpaper do I need? The answer isn’t always as straightforward as it seems, especially when you’re factoring in wall dimensions, pattern repeats and roll quantities.

That’s exactly why we created our easy-to-use wallpaper calculator and measuring guide at ModEco Home.

Instead of trying to work everything out manually, our calculator removes the uncertainty and helps you order with confidence. Simply measure your walls, enter your dimensions, and let the calculator do the hard work for you. Whether you’re decorating a feature wall or transforming an entire room with our luxury wallpaper collection, getting the right quantity has never been easier.

How to Measure Your Walls

To use our wallpaper calculator, simply measure:

  • The total width of the wall or walls you want to cover.
  • The highest point of the wall from floor to ceiling.

When taking your measurements, we always recommend adding at least 2 inches (5cm) to both the width and height. Very few walls are perfectly straight, and many homes have slightly uneven ceilings, sloping floors, or walls that aren’t completely square. Allowing this extra margin gives your installer room to trim the wallpaper for a perfect finish and helps avoid any issues caused by wonky walls.

Once you’ve taken your measurements, enter them into our calculator, and it will instantly work out:

  • The total square metres required.
  • The exact amount of wallpaper needed.
  • The price of your wallpaper based on your measurements.

This means you’ll know exactly what you’re ordering before you proceed to checkout.

A Smarter Way to Buy Designer Wallpaper

Unlike traditional wallpaper companies that sell standard rolls and often leave customers with excess material, our calculator allows us to create wallpaper based on your specific wall dimensions.

Not only do we print your wallpaper to your custom measurements, but we also supply it already pattern matched for your wall. This means you don’t have to worry about lining up complex pattern repeats during installation.

Whether your chosen design features a straight match, half-drop repeat, or half-brick repeat, we’ll prepare the panels so the pattern flows seamlessly across your wall. It takes away the headache of working out difficult pattern matches and makes installation quicker, easier, and more accurate.

By producing wallpaper to fit your space and pre-matching the pattern for you, we significantly reduce unnecessary waste. All you have to do is butt the panels up next to each other, simple! This approach is at the heart of what we do at ModEco Home.

Our Unique Mock-Up Service

Once you’ve placed your order, our service doesn’t stop there.

We’ll personally get in touch and provide you with three different design mock-ups based on the measurements you’ve supplied:

Small scale

Medium scale

Large scale

This allows you to see how the pattern will look on your wall before production begins and choose the scale that best suits your space.

A bold mural may look stunning at a larger scale, while a more intricate design may work better at a smaller scale. By offering these options, we ensure your wallpaper feels perfectly proportioned to your room.

As far as we’re aware, this is a service that is completely unique to ModEco Home and something you won’t find with other wallpaper companies.
