Specifying custom wallpaper for a commercial project is very different from choosing wallpaper for a living room. Commercial interiors involve larger surfaces, multiple decision-makers, demanding environments, technical requirements, and tighter installation schedules. A small mistake in measurement, material selection, artwork preparation, or installation planning can affect the entire finished space.
The good news is that most common wallpaper problems can be avoided with a structured specification process.
From accurately measuring the wall and selecting the right substrate to approving artwork, considering fire and durability requirements, and planning installation, every stage plays a role in achieving the intended result.
Custom wallpaper murals transform an original design into a precisely scaled, panel-printed wall covering created specifically for a particular wall. Unlike standard wallpaper rolls, the artwork can be adjusted to suit the wall's dimensions, architectural features, and overall interior concept. There are no standard-size limitations or awkward compromises caused by trying to make an existing design fit.
When properly specified, custom wallpaper becomes an integrated part of the interior rather than something added at the end of the project.
Key Takeaways
Accurate wall measurement is the foundation: Every design, panel, and print specification depends on precise dimensions.
Wallpaper material is a functional decision: The substrate should be selected according to the environment, traffic level, cleaning requirements, and expected lifespan.
Commercial projects require additional planning: Fire performance, durability, maintenance, installation conditions, and stakeholder approvals may all influence the specification.
Use a structured briefing framework: Consider the Surface, Environment, Audience, and Longevity before selecting a wallpaper.
Artwork needs careful preparation: Scale, resolution, colour, cropping, panel breaks, and architectural obstructions should all be reviewed before production.
Installation is part of the specification: Even a perfectly printed mural can fail if the wall is not prepared correctly or the panels are installed incorrectly.
Custom wallpaper isn't suitable for every situation: Understanding its limitations helps designers choose the right solution for each project.
Why Do So Many Commercial Walls End Up Feeling Like an Afterthought?
The problem is rarely a lack of creativity or budget. More often, the wall simply enters the specification process too late.
In a typical commercial fit-out, flooring, lighting, furniture, joinery, and other major elements are discussed early because they influence the rest of the design. Wall finishes can sometimes be left until much later in the programme.
By that stage, the design may already be largely established, the installation schedule may be compressed, and the contingency budget may be limited.
Yet walls often represent some of the largest uninterrupted visual surfaces within a commercial interior.
A blank wall in a hotel, restaurant, office, retail space, school, healthcare facility, or reception area can influence how the entire environment feels. It can establish a brand identity, communicate a location, introduce colour and texture, or create a memorable focal point.
The issue, therefore, isn't necessarily the design itself.
It's the process.
When wallpaper is considered from the beginning, designers can create artwork around furniture layouts, lighting, architectural features, circulation routes, and brand requirements. When it is considered at the end, the result can feel like an addition rather than part of the original interior concept.
This is why custom wallpaper should be treated as a design and specification decision rather than simply a decorative product.
What Does the Custom Wallpaper Specification Process Actually Look Like?
Many people assume the process begins with selecting an attractive wallpaper design.
It doesn't.
The process begins with understanding the wall.
- Start With Accurate Wall Measurements
Accurate measurement is one of the most important stages of any custom wallpaper project.
The width and height of the wall should be measured carefully, ideally at multiple points, because walls are not always perfectly square or uniform.
Designers should also record the position and dimensions of:
Doors
Windows
Columns
Sockets and switches
Recesses
Alcoves
Radiators
Built-in furniture
Wall-mounted screens
Architectural features
Other permanent obstructions
A useful measurement drawing or site plan can make the production process significantly easier.
For complex commercial projects, it is also important to establish which dimensions are finished dimensions and which may change during construction.
A mural produced before final wall dimensions are confirmed can create unnecessary problems later.

- Consider the Wall Surface
Once dimensions have been established, the condition of the wall needs to be assessed.
Custom wallpaper does not automatically hide every surface imperfection. Uneven plaster, cracks, holes, moisture problems, dust, loose paint, or significant texture can affect the final appearance.
Before installation, the wall may need to be:
Cleaned
Filled
Sanded
Primed
Smoothed
Dried
Sealed where necessary
A beautifully printed mural cannot compensate for an unsuitable installation surface.
For commercial specifications, wall preparation should therefore be included in the project planning rather than treated as an installation-day issue.
- Choose the Design Around the Wall
Once the wall dimensions and surface conditions are understood, design selection becomes much more meaningful.
Wallpapered's catalogue includes botanical, architectural, photographic, abstract, map, and typographic designs that can be adapted to suit different interiors.
The objective isn't simply to find a design that looks good online.
The design needs to work on the specific wall.
Consider:
Where the focal point of the artwork will sit
How the image interacts with doors and windows
Where furniture will be positioned
Whether important visual elements will be hidden
How the design works from different viewing distances
Whether the artwork complements the brand identity
How the design interacts with lighting
Whether the scale feels appropriate for the room
For example, an intricate botanical design may work beautifully across a large hotel wall but could lose its impact if the most detailed area is positioned behind a reception desk.
Customisation allows the artwork to be cropped, scaled, positioned, or adjusted around these practical considerations.
- Think About Artwork Resolution and Scale
Large-format wallpaper requires more than simply enlarging an image.
An image that looks sharp on a laptop screen may not perform well when reproduced across a several-metre-wide wall.
Before production, designers should consider the original artwork resolution, intended viewing distance, image detail, colour requirements, and final print dimensions.
Vector artwork can be particularly useful for logos, typography, patterns, maps, and graphic elements because it can be scaled without the same loss of sharpness associated with raster images.
For photographic murals, the original image quality becomes especially important.
The earlier artwork suitability is checked, the less likely it is that problems will appear after design approval.
- Select the Right Wallpaper Material
This is one of the most frequently underestimated decisions in commercial wallpaper specification.
Wallpaper material is not simply about choosing a preferred texture or finish. It is a functional specification that should reflect the environment in which the wallpaper will be installed.
Different spaces place different demands on a wall covering.
A hotel bedroom, restaurant, office reception, retail store, gym, school corridor, and healthcare environment may all require different performance characteristics.Wallpapers
