Ordering & sizing
Measure the full wall width and height in cm. Measure in a few places (top/middle/bottom for width, left/centre/right for height) and use the largest measurement.
Tip: For murals we recommend adding 10 cm extra to both width and height for trimming.
We calculate the wall area in m² after adding the recommended trim (extra 10 cm on each side).
- Area (m²) = ( (width+10)/100 ) × ( (height+10)/100 )
- Billed area is rounded up to the next whole m² and may have a minimum billed area depending on the product.
If you’re unsure, send us your wall size and we’ll confirm the correct order size before you purchase.
We offer both, depending on the product: some designs are sold as standard wallpaper, and some murals are printed to your wall size in panels.
Check the product page for the material type and sizing options. If you don’t see the calculator on a mural product, contact us and we’ll fix it or provide a manual quote.
Proper preparation ensures that your wallpaper adheres correctly to the wall. If the wallpaper hasn’t formed a good bond, it may peel or fall off the wall. Proper prep work also prevents damage to the underlying surface if the paper is removed in the future.
For best results, consult with the experts at Allinone Design Wallpaper. We can help you avoid costly and time-consuming by making sure the job is done right the first time.
- Peel & Stick: self-adhesive backing. Best for smooth, clean, well-painted walls. Easier DIY install.
- Non-woven: installed with wallpaper paste (typically paste-the-wall). Strong, stable and ideal for long-term installs.
Not sure which to choose? Tell us your wall type and room (bedroom, nursery, rental, etc.) and we’ll recommend the right option.
We recommend a smooth, properly prepared surface. Heavy texture, raw brick, or damaged walls may require preparation (skimming, sanding, sealing, or lining paper) for the best finish.
If you share a photo of the wall, we can advise the safest approach before ordering.
