Preparing photos for wallpaper and canvas

Large format prints show every strength and every flaw in a photo. If you want wallpaper or canvas that looks clean from across the room and still holds up close, start with the right file and a sensible plan.

Start with the best original image

The first rule is simple: send the original file, not one that has been forwarded many times on a chat app or pulled from social media. Wallpaper and canvas are printed much larger than a phone screen, so small files quickly show blur, blockiness and rough edges. A sharp photo taken on a good phone can still work well, but only if the original image is supplied at full size.

If you are choosing between several photos, pick the one with the cleanest focus and the best light. Bright daylight usually prints better than dark indoor shots because there is more detail in shadows and less digital noise. Try not to use screenshots. They often look acceptable on a handset, but on a wall panel or stretched canvas they come apart quite fast.

  • Use the original camera file where possible.
  • Avoid screenshots, social media downloads and chat app versions.
  • Choose sharp focus over heavy filters.
  • Natural light usually gives better print detail.
  • If a photo looks soft when zoomed in, it will print soft too.

Match the image to the final print size

Before any file is checked properly, you need the finished size. For wallpaper, measure wall width and height in millimetres and include extra allowance for trimming. For canvas, decide the face size and whether the image will wrap around the sides or stop on the front face only. These choices affect cropping more than most customers expect.

A tall narrow photo may suit a hallway canvas but not a full lounge wall. A wide beach scene can work beautifully for wallpaper, yet lose important detail if forced into a square canvas. It helps to think in shapes first: portrait, landscape or square. Our team can advise on practical cropping, but a quick test at your side saves time.

Open the photo on a larger screen if you can and crop it roughly to the same shape as the wall or canvas. This shows what will be lost at the edges. Quite often the main subject sits too close to the border, and then a better image choice is needed.

  • Measure the wall or canvas area accurately in millimetres.
  • Allow extra trim on wallpaper panels.
  • Check whether canvas sides will wrap with image or colour.
  • Test the crop to the final shape before sending.
  • Keep key faces, logos and details away from the edges.

Understand resolution without overcomplicating it

Resolution matters, but it does not need to become technical drama. For close-viewed canvas prints, higher detail is better because people stand near them. Wallpaper is usually seen from a bit further back, so a file can still print well even if it is not perfect on every pixel. What matters most is whether the image holds together at the final size.

As a practical guide, a full wall image needs a much larger file than an A-sized poster. If you send a low-resolution image and ask for it to fill a bedroom wall, the printer cannot invent missing detail. Enlarging a poor file only makes the weakness bigger. Some photos can be improved slightly with careful preparation, but no file can be rescued endlessly.

If you are unsure, send the file along with the intended finished size through the contact page. We can check if it is suitable for wallpaper or canvas and advise whether to reduce the size, crop differently or choose another image.

Prepare colour, contrast and finishing properly

Print behaves differently from a glowing screen. Phone and laptop displays often make colours look brighter and punchier than they will appear on printed material. Very dark photos can print muddy, especially in shadow areas. Very bright whites can also lose detail. A small adjustment to contrast and brightness can help, but heavy editing usually causes more trouble than it solves.

For wallpaper, busy patterns and very saturated colours can feel overpowering once they cover an entire room. For canvas, strong contrast often works well, especially in living rooms, entrance areas and office walls. If the image includes skin tones, avoid extreme filters. They may look trendy on screen, but on a large print they often appear artificial.

  • Keep edits light and natural.
  • Avoid strong filters that change skin tones or skies too much.
  • Lift very dark images slightly so shadow detail remains visible.
  • Check for blown highlights in clouds, windows or white clothing.
  • If in doubt, send the clean original rather than an over-edited copy.

Choose the right file format and send it cleanly

Good file handling prevents delays. High quality JPG files are fine for many wallpaper and canvas jobs, provided they are exported at full size and not compressed heavily. PNG files can also work, especially for artwork and graphics. If you have a layered working file from a photographer or designer, export a flattened high quality version for review unless you are asked for something else.

Name files clearly so nothing gets mixed up, especially if you are sending options for different rooms or more than one canvas size. If there are special instructions, include them in your message through the contact form. Say which image goes on which wall, whether you want black and white, and if any section must remain visible after cropping. A little clarity here saves back and forth later.

  • Send full-size JPG or PNG files where possible.
  • Do not paste images into a document file.
  • Use clear file names for each room or print size.
  • State final dimensions and any crop instructions.
  • Upload the largest version you have, not the easiest one to send.

Final checks before you submit

Take five minutes for a last review before sending everything through. Zoom into the image and check faces, horizon lines, fine textures and any text inside the artwork. Look for obvious issues like motion blur, low light grain, clipped edges or unwanted objects in the background. On wallpaper especially, tiny distractions become very noticeable once they are two or three metres wide.

Also think about the room itself. A photo that works beautifully in a bright Umhlanga apartment may feel too dark in a smaller inland room with less natural light. In coastal areas around Durban, light is often strong during the day, so contrast and colour can feel different from what you saw on a screen at night. It sounds small, but these details matter.

If you are not certain, send two or three options with your preferred choice marked clearly. That gives our print team something practical to work with, and we can recommend the image most likely to produce a clean result on wallpaper or canvas. Use the enquiry form on the contact page and include your sizes, room type and files in one go if you can.

Questions we get asked

Can a phone photo be used for wallpaper or canvas?

Yes, if it is the original full-size file and the photo is sharp, well lit and suitable for the final print size. Chat app copies and social media downloads are often too small.

What if I do not know whether my image is high enough quality?

Send the file with the intended wall or canvas size through the contact form. We can check whether it is suitable as is, needs a different crop, or should be printed at a smaller size.

Should I edit the photo before sending it?

Basic brightness and contrast adjustments are fine, but keep them light. Strong filters, over-sharpening and heavy colour changes often print poorly on large formats.
