Wallpaper Size & Materials Guide (Archived Full Version)

Wallpaper Size & Materials Guide

Choose the right material, measure your wall, and work out how many rolls you need.

Archived reference copy. This version includes the manual roll-measuring worksheet, which the roll calculator on each product page now replaces. The current guide is at Wallpaper Size & Materials Guide.

Materials

Every design is available in three materials. All three are Class A fire rated and Prop 65 compliant. They look and install differently, so choose based on your wall and your situation. Swatches are shown at 2× zoom — tap any swatch to enlarge it.

Vinyl Peel & Stick

  • Smooth surface with a slightly satin sheen

Fabric Peel & Stick

  • Matte finish over a very fine micro-weave
  • Durable and easy to clean
  • The easiest of the three to install
  • Can indirectly support LEED v4 credits through its material composition and environmental profile
  • The renter-friendly choice — removes without damaging paint

Unpasted Traditional

  • Type II 20oz textured non-adhesive wallpaper, non-woven backing
  • Best for slightly textured walls
  • Hung with heavy-weight wallpaper paste — paste is not included
  • Widely used in commercial settings
  • How well it holds, and how easily it comes off later, depends on the paste your installer uses

Before you order, check two things.

1. Your paint. Peel and stick wallpaper — fabric or vinyl — is not compatible with Sherwin Williams ProMar 400 Zero VOC paints, or any paint marketed as Stain-Resistant, Anti-Stain, or Anti-microbial, unless you first prime the wall with Roman Pro-935 R-35 Primer.

2. How recently you painted. If the wall has been painted recently, wait 30 days before installing. Fresh paint needs to fully cure and finish outgassing — installing sooner risks adhesion problems.

Around 99% of peel-and-stick failures come down to wall texture or paint incompatibility, and because everything is made to order we can't accept returns for wall incompatibility. If you're unsure, send us a photo first.

Sizes

Samples — 8 × 11 inches, or 24 × 24 inches. Worth ordering before a full room: colours read differently under different lighting, and for large-scale designs the 24 × 24 inch sample shows the pattern at true scale.

Rolls — all 24 inches wide, in four lengths: 24 × 60, 24 × 96, 24 × 108 and 24 × 122 inches.

Need a size we don't list? Custom sizes are available. Use the wallpaper calculator on any product page to work out your measurements, then send us a size request and we'll quote it.

How many rolls do I need?
  1. Measure your wall height — the papered area only. Do not include base trim, crown moulding, or anything below a chair rail.
  2. Pick a roll 2 to 4 inches longer than that height. The excess is trimmed after installation.
  3. Divide your wall width by 24 inches and round up. That's how many rolls you need.

Every product page also has a roll calculator that does this for you.

Example 1 — standard wall

Wall: 132 inches wide × 93 inches high, excluding base trim.

dashed outline = 6 rolls of 24 × 96 in 132 in wide24 intrim12 in trimmed from the width, 3 in trimmed over the base trim 93 in high — excludes base trim

132 ÷ 24 = 5.5, rounded up to 6 rolls. A 93 inch wall needs 95–97 inches of length, so the 24 × 96 inch roll is right. The extra hangs over the base trim and is trimmed off, along with 12 inches from the right edge.

Example 2 — wall above a chair rail

Wall: 108 inches wide × 55 inches high above the chair rail. You only paper the area above the rail — the wainscotting and base trim below it are not measured.

dashed outline = 5 rolls of 24 × 60 in 108 in wide24 intrim12 in trimmed from the width, 5 in trimmed over the chair rail 55 in high — above chair rail

108 ÷ 24 = 4.5, rounded up to 5 rolls. A 55 inch wall needs 57–59 inches of length, so the 24 × 60 inch roll is right. The extra hangs over the chair rail and is trimmed off, along with 12 inches from the right edge.

Single-roll vs multi-roll repeats

Designs fall into two groups, and it changes how you order.

  • Single-roll repeat — the pattern repeats within one roll, so every roll is identical and interchangeable.
  • Multi-roll repeat — the pattern repeats across 2, 3, 4 or 5 rolls, so each roll is a specific panel in the sequence. All murals work this way, and mural patterns do not repeat vertically at all.

Check the product page for the repeat before you order. If you're placing a multi-roll order in mixed roll lengths, tell us which panel numbers go with which length in the notes at checkout — for example, panels 1 and 2 in 96 inch, panels 3, 4 and 5 in 108 inch. Without that, your order may be delayed. Some murals cannot be mixed between sizes at all — the product page will say so.

Common questions
I just painted — how long should I wait before installing?
Wait 30 days. Fresh paint needs to fully cure and finish outgassing before wallpaper goes on. Installing sooner is one of the most common causes of adhesion failure.
Should I order an extra roll?
It depends on the design. Single-roll repeats: yes — every roll is identical, so a spare is useful, and a later top-up order may not colour-match exactly. Multi-roll repeats and murals: no — each roll is a specific panel in the sequence, so a generic spare roll doesn't apply. Order the exact panels you need, and contact us if you're unsure which repeat your design has.
Can I get a custom size?
Yes. Use the wallpaper calculator on any product page to work out your measurements, then send us a size request and we'll quote it for you.
What's the difference in finish between vinyl and fabric?
Fabric Peel & Stick is matte, over a very fine micro-weave. Vinyl Peel & Stick is smooth, with a slightly satin sheen. Both are durable and easy to clean.
Which material should I choose if I'm renting?
Fabric Peel & Stick. It removes without damaging paint, so you can put the wall back as you found it.
Will it work on a textured wall?
Unpasted Traditional suits slightly textured walls. For peel and stick, the more texture a wall has, the less surface area the adhesive can grip — heavily textured or bumpy walls may need skim-coating first. If you're unsure about your wall, send us a photo through chat or email [email protected] and we'll check before you order.
Which paints are not compatible?
Sherwin Williams ProMar 400 Zero VOC, and any paint marketed as Stain-Resistant, Anti-Stain or Anti-microbial. You can still use these walls if you first prime with Roman Pro-935 R-35 Primer.
Which peel and stick material has the stronger adhesive?
Vinyl Peel & Stick — it has the higher tack of the two peel and stick materials. We recommend using it with the E-Z Hang Peel & Stick Helper. Unpasted Traditional isn't part of that comparison: it has no adhesive of its own, so how firmly it holds depends entirely on the paste your installer uses.
Do I measure the full floor-to-ceiling height?
No. Measure only the area you're papering. Exclude base trim, crown moulding, and anything below a chair rail.
What roll length should I order?
Measure the papered height of your wall, then choose a roll 2 to 4 inches longer. Trim the excess after installation.
Are these fire rated? Are they Prop 65 compliant?
Yes to both. All three materials are Class A fire rated and Prop 65 compliant. Fabric Peel & Stick can also indirectly support LEED v4 credits through its material composition and environmental profile.
Can I use wallpaper in a bathroom or kitchen?
Yes. All three materials handle bathroom and kitchen humidity, and all are water resistant — they can be wiped down with water and a damp cloth. Test any chemical cleaner in an inconspicuous spot first.
Is wallpaper paste included with unpasted wallpaper?
No. Unpasted Traditional needs heavy-weight wallpaper paste, supplied separately.
