Table Trimming
The wallpaper is laid out on a work table and the selvage is trimmed off before installation. This is often the safer and more controlled method for many residential wallcoverings.

Untrimmed Wallpaper: What It Is, Why It Costs More, and How It Should Be Installed
Untrimmed wallpaper is wallpaper that arrives with extra factory edges, called selvage, that must be trimmed before installation. Unlike pre-trimmed wallpaper, it requires an additional step, more planning, and a higher level of precision.
Many premium and traditional wallpapers come untrimmed for a reason. The extra edge can help protect the roll during shipping and give more control when aligning seams and pattern repeats. Before choosing untrimmed wallpaper, it is important to understand that the installation method, labor time, and total cost may be very different from a standard wallpaper project.
Quick Facts About Untrimmed Wallpaper
- Factory edges are not pre-cut
- The selvage must be trimmed before installation
- Some wallpapers are better trimmed on a table
- Some can be double cut on the wall
- Installation usually costs more than pre-trimmed wallpaper
- Not every material should be installed the same way
- Experience matters much more with untrimmed wallcoverings
IMPORTANT
Untrimmed wallpaper is not automatically low quality or defective.
In many cases, it is a premium wallcovering that simply requires
more labor, more experience, and a more careful installation
method.
What Is Untrimmed Wallpaper?
Untrimmed wallpaper arrives with extra blank edges along the sides of the roll. These edges are called selvage. Before the wallpaper can be installed properly, the selvage must be removed so the seams can align correctly.
Many untrimmed wallpapers also include trim or join marks that show where the material should be cut and aligned. If the design already runs to the edge and no selvage is present, the wallpaper is pre-trimmed instead.
Why Some Wallpaper Comes Untrimmed
Many homeowners assume that untrimmed wallpaper is unfinished or lower quality, but that is often not true. Many premium, traditional, and screen-printed wallpapers are intentionally manufactured this way.
The extra selvage can help protect the edges during shipping and provide better control when aligning pattern repeat and matching seams. In other words, untrimmed wallpaper is often a manufacturing choice that shifts more responsibility to the installer, not a sign of a poor product.
IMPORTANT
Some of the most beautiful wallpapers on the market come
untrimmed. The real issue is not the wallpaper itself — it is
whether the right trimming method is chosen for that specific
material.
Not All Untrimmed Wallpaper Is Installed the Same Way
This is one of the most important things to understand about untrimmed wallpaper. There is no single installation method that works for every material.
Some untrimmed wallpapers are best trimmed on a table before hanging. Others may be installed using a double-cut method on the wall. The correct approach depends on the material, the print, the finish, the wall condition, and the level of installation experience required.
Double Cutting on the Wall
Two drops are overlapped and cut through together on the wall to create a clean seam. This method can work very well in the right hands, but it is more technical and comes with more risk.
Method Depends on Material
Some wallpapers tolerate double cutting well. Others are safer to trim on a table, especially when the face material, ink, finish, or substrate is more delicate.
Why Untrimmed Wallpaper Costs More to Install
Untrimmed wallpaper installation usually involves more labor than standard pre-trimmed wallpaper. The material may need to be inspected first, the correct trimming method must be chosen, each edge may need to be cut by hand, and seam work usually moves more slowly.
That added labor is one of the main reasons untrimmed wallpaper installation is often priced significantly higher than standard wallpaper installation. In many cases, homeowners should expect the cost to be noticeably higher because the work is slower, the risk is greater, and mistakes are harder to correct.
IMPORTANT
Untrimmed wallpaper is not just “more wallpaper installation.” It
is a more specialized process that requires additional time,
control, and responsibility.
When Double Cutting Makes Sense — and When It Doesn’t
Double cutting can produce a clean, professional seam when used on the right material and with the proper tools. But it is not the right choice for every wallpaper.
One of the main risks of double cutting is damaging the wall surface below the wallpaper. If that happens, the seam area may become more vulnerable over time. Another challenge is keeping paste away from the decorative face of the material, especially with delicate wallcoverings. That is why double cutting should be treated as a professional method, not a default method.
IMPORTANT
Choosing the wrong trimming method can damage the wallpaper, stain
the surface, or create visible seam problems.
Risks Homeowners Should Understand Before Ordering Untrimmed Wallpaper
Before ordering untrimmed wallpaper, homeowners should understand that not every installer accepts it, not every material should be installed the same way, and not every project is a good candidate for it.
Compared with standard wallpaper, untrimmed materials may require more labor, more waste allowance, more planning, and more careful wall preparation. If the wrong method is used, the result can include damaged edges, seam problems, staining, or unnecessary risk to the wall surface.
- Higher labor cost
- More setup and trimming time
- More responsibility during seam work
- Not every installer accepts every untrimmed material
- Best reviewed before installation day
Installation Considerations
Untrimmed wallpaper requires more than careful hanging. It requires choosing the right method before the first strip goes on the wall.
Smooth wall preparation, proper primer, accurate layout planning, and controlled seam work all matter more on untrimmed projects because there are extra steps and less margin for error.

Is Untrimmed Wallpaper Right for Your Project?
Untrimmed wallpaper can be an excellent choice, especially when you are working with a premium product and the right level of installation experience. But it is not always the simplest or most forgiving option.
If you are considering untrimmed wallpaper, the best first step is to review the product details before installation is booked. A wallpaper link, brand information, material type, and photos of the walls can help determine whether the wallpaper should be table-trimmed, double cut, or avoided altogether.
Before Scheduling Installation
If you already selected an untrimmed wallpaper, send the wallpaper link, brand name, material details, and photos of your walls before scheduling installation. That review helps determine the correct installation method, the level of difficulty, and whether the material is a good fit for the project.
