At Wall Blush, every wallpaper order is made specifically for your wall. That means accurate measurements are everything. The good news? Measuring is simple when you follow the right steps.
Part 1: How to Measure Your Wall for Wallpaper
Because our wallpaper is made-to-order for your exact space, precision matters. But don’t overthink it — it’s easier than you think.
Step 1: Measure the Full Width
Measure the entire width of your wall from corner to corner.
Do not subtract:
- Windows
- Doors
- Built-ins
- Trim
- Cabinets
Even if half the wall is made up of windows — measure the full width.
Step 2: Measure the Full Height
Measure from:
- Floor to ceiling
- OR baseboard to ceiling (if you plan to install above the baseboard)
Again — do not subtract anything.
Step 3: Enter the Total Wall Size
When ordering, enter the full width and full height of the wall as if it were one solid rectangle.
Why You Don’t Subtract Windows or Doors
It may feel logical to subtract windows and doors — but don’t.
- Wallpaper is printed in vertical panels.
- The design needs to align properly across the entire wall.
- Subtracting spaces can cause pattern breaks and alignment issues.
- It’s better to trim excess material during installation than to come up short.
Think of your wall as one complete canvas. Windows and doors are simply cut out during installation.
Pro Tip: Add a Little Extra
While we calculate panels based on your measurements, it’s always smart to double-check measurements and round up. Walls are rarely perfectly square.
Part 2: How to Install Wallpaper Around Windows
Installing around windows may look intimidating — but it’s completely manageable with a little patience.
Here’s exactly how to do it.
Step 1: Install the Panel Normally
Hang the wallpaper panel straight down over the window — just like you would on a solid wall.
Important: Do not cut the window out before applying.
Smooth the panel fully onto the wall first.
Step 2: Locate the Window Edges
Once the wallpaper is adhered and smoothed:
- Gently feel for the window edges beneath the paper.
- Use a sharp utility knife.
- Cut an “X” shape from corner to corner inside the window opening.
Step 3: Trim Carefully Along the Edges
After cutting the “X”:
- Fold the excess wallpaper inward toward the frame.
- Carefully trim along the window edge using the frame as your guide.
- Use slow, controlled cuts for a crisp finish.
Pro Tip: Always use a fresh blade for clean edges.
Step 4: Smooth and Finish
Press down all edges firmly.
If needed:
- Use a smoothing tool for tight corners.
- Lightly warm peel and stick material with a hair dryer to help it conform around trim.
The result? A seamless, built-in look.
Common Questions
What if my window has trim?
No problem. Install the wallpaper to the edge of the trim and trim flush against it.
What if my walls aren’t perfectly straight?
That’s normal. Always align your panels using a level or plumb line — not the ceiling or trim.
What if I’m nervous?
Order a sample first. It’s the best way to see the material, test installation, and feel confident before committing to the full wall.
Final Thoughts
Measuring correctly ensures your wallpaper fits your space beautifully. And installing around windows? It’s simply a matter of applying first, trimming second.
At Wall Blush, we design wallpaper to make transformation simple — even in spaces with windows, doors, and architectural details.
Measure the full wall. Install with confidence. Trim to perfection. And enjoy a space that feels completely custom to you.
