How to Order a Custom Mural for Your Wall Size

Ordering a custom mural tailored to your exact wall size is easier than you might think.

Whether you’re transforming a full feature wall, decorating an awkward alcove or creating a perfectly fitted statement piece, custom sizing ensures your chosen design looks seamless and professionally finished.

In this guide, we’ll walk you through how to measure your wall, upload your dimensions and order a mural made to fit your space perfectly. We’ll also highlight examples of customers we’ve helped to navigate tricky projects with outstanding results.

Why Exact Sizing Matters More Than You'd Think

We helped this customer with an eye-catching bathroom mural that needed to account for the sloped wall and door. 

A mural that doesn't fit your wall properly causes problems — awkward white strips at the edges, cropped focal points, or a design that doesn't fill the space as you imagined. Walls aren't always perfectly square. Older homes especially tend to have walls where the height on one side can differ from the other by a centimetre or two. A genuinely bespoke service accounts for that.

Beyond aesthetics, the right fit saves you money. You avoid paying for excess material and spending a weekend figuring out how to disguise gaps. Once you spot an issue, it's difficult to forget that it's there. Avoid buyer's regret by taking extra care when measuring.

House Beautiful named wall murals among the top 11 interior trends already dominating this year. Demand has never been higher — and neither has the expectation that your mural will fit perfectly.

How to Measure Your Wall Correctly

We helped this customer create a stunning floral accent wall that perfectly fits their imperfect wall.

Before you order anything, you need accurate measurements. It sounds obvious, but this is where most ordering mistakes happen.

• Measure the full width of the wall at the top, middle and bottom — walls are often slightly uneven
• Measure the height on both the left and right sides
• Use the largest measurements you record as your ordering dimensions
• Add a small margin (a few centimetres), so you have a little trimming room during installation

For anything non-standard — alcoves, sloped ceilings, walls around a fireplace breast — it might be worth speaking to an expert before ordering. Wallsauce offers a detailed wall measuring guide covering standard and tricky wall shapes, worth bookmarking before you start measuring.

Where to Order a Custom Wall Mural to Fit an Exact Size

This customer chose a stylish William Morris mural that was measured perfectly to account for the chimney breast and window.

Wallsauce can help anyone wanting a truly bespoke mural without a complicated ordering process. Every mural is printed to your exact dimensions — just enter your width and height in centimetres or inches, and the design is scaled accordingly. There are no size restrictions beyond what the image resolution supports.

Our catalogue is packed with thousands of designs across categories including botanicals, architecture, fine art, children's themes, abstract and textures. If none of those fit your vision, you can upload your own photo or artwork and have it printed as a full wall mural at any size you specify.

There are a few services that set us apart:

• Free room mock-up — send a photo of your wall and the team will show you how a chosen design looks in your actual space before you commit
• MeasureSafe guarantee — if your mural doesn't fit due to an undermeasuring issue, Wallsauce will reprint the full mural and you'll only pay the difference
• Multiple material options — choose from classic, premium or deluxe paste-the-wall and peel-and-stick finishes depending on your preference
• Express shipping — orders are dispatched within 1–2 days, with free UK delivery in 2–4 business days
• UK production — all murals are printed in the UK using PVC-free materials and environmentally-friendly inks

For renters or anyone wanting a temporary solution, the peel-and-stick option is perfect — it applies like normal wallpaper, comes off cleanly, and can be repositioned if needed.

What to Think About Before You Order

A gorgeous pink and green parrot paradise mural that fits the sloped walls to perfection.

Material. Paste-the-wall options are durable and provide a seamless finish. Removable wallpaper suits renters or anyone likely to redecorate within a few years. Both are available from Wallsauce with the same bespoke sizing.

Image resolution. If uploading your own photo, aim for at least 12 megapixels (about 4,256 × 2,848 pixels) at 300 dpi for a crisp result at full wall scale. Wallsauce's upload tool flags any resolution concerns before you proceed.

Room and design match. Living room wall murals differ from bedroom mural ideas — scale, colour palette, and the amount of wall visible around furniture all affect which design works best in each room. 

The Ordering Process from Start to Finish

Transform a staircase with a made to measure abstract mural like this customer has.

With Wallsauce the process takes about five minutes once you've got your measurements:

1. Browse the catalogue or upload your image
2. Enter your exact wall dimensions (width × height)
3. Crop and position the design within your dimensions
4. Choose your material
5. Check out — your mural is immediately sent for review

Panels arrive numbered and ready to hang in order, with installation guides included. If you want to see it first, request the free room mock-up before you reach the checkout.

Simple and Straightforward Wall Mural Installation

We helped this customer to create a seamless effect with a stunning terrazzo mural that isn't restricted to just their wall.

Taking the time to order your mural to the exact dimensions of your wall also makes installation far easier and more accurate.

A perfectly sized mural means each panel aligns correctly with your space, helping to reduce trimming, awkward joins and unnecessary waste during installation.

Whether you’re working around alcoves, sloped ceilings or feature walls, a made-to-measure mural creates a smoother application process and delivers a cleaner, more professional-looking finish once installed.

There is no reason to settle for a fixed-size mural that almost fits. Made-to-measure ordering costs no more, takes no longer, and the result is a wall that looks like it was designed specifically for that room because it was.
