Turn Your Own Photo Into Canvas: Resolution, Files & Tips

Some of the best canvases on people’s walls aren’t stock art at all — they’re a photo from a trip, a wedding, a favourite view, or a much-loved pet. Printing your own image on canvas is straightforward, but a few things decide whether it comes out crisp or soft. Here’s what actually matters, in plain terms.

The short answer

• Start from the largest, original file you have — not a screenshot or a social-media download.
• Aim for around 150 pixels per inch (PPI) at your finished print size for a sharp result.
• Send a high-quality JPEG, PNG or TIFF, and don’t upscale a small image to fake resolution.

Get those three right and almost any modern phone or camera photo will make a lovely canvas.

Resolution: how big can your photo go?

Resolution is just how many pixels your image has to spread across the print. The more pixels, the larger you can go before detail turns soft. As a practical rule, divide each pixel dimension by 150 to get a comfortable maximum print size in inches (then multiply by 2.54 for centimetres).

So a 4000 × 3000 px photo — typical of a recent phone — prints cleanly at roughly 26 × 20 inches (about 68 × 51 cm). Viewed from across a room, canvas is forgiving, so you can often push a little larger than the numbers suggest; the texture of the weave hides minor softness that would show on glossy paper.

These are guidelines, not hard limits — canvas texture and normal viewing distance give you some headroom.

File types: what to send

• JPEG — perfect for photos. Just save or export at the highest quality setting; avoid re-saving the same JPEG many times, as each save loses a little detail.
• TIFF or PNG — lossless, ideal if you have them, especially for artwork and graphics with crisp edges.
• Avoid screenshots, images saved from messaging apps, or anything pulled off social media — these are heavily compressed and shrunk, and won’t print large.

Getting the crop and shape right

Your photo has a shape (aspect ratio), and so does the canvas. If they don’t match, something has to be cropped. Decide early whether the image suits landscape, portrait or square, and leave a little space around the main subject so nothing important sits right at the edge — the gallery wrap folds a few centimetres of the image around the sides of the frame. We support 13 aspect ratios, so most photos land on a shape that keeps the composition intact.

A few quick quality tips

• Use the original, not a copy of a copy. Dig out the file straight from your phone or camera roll rather than one that’s been forwarded around.
• Don’t upscale to hit a number. Enlarging a small image in software adds pixels but not real detail — it usually looks softer, not sharper.
• Mind the light in the original. A slightly dark or noisy photo will print darker; brighten and clean it up before ordering if you can.
• Colours shift a touch on canvas. The matte, textured surface reads a hair softer and warmer than a bright screen — lovely for most photos, worth knowing for critical colour.

Not sure your photo is big enough?

Send it over and we’ll check the resolution against the size you want before anything is printed — no guessing, no wasted canvas. We print custom dimensions to the millimetre, up to 170 × 500 cm, and there’s no extra charge for printing your own image in a custom size.
