Which canvas print size to choose
The size of a picture decides whether it lifts the wall or gets lost on it. How to choose a canvas print format by the wall, the subject and the resolution of your photograph.
Format matters more than subject
When you have a photograph printed on canvas, most of the time usually goes on choosing the image. Yet something else decides the final impression — the size. The same photograph can lift a wall in one format and look like a footnote on it in another.
The most common mistake is a picture too small for the wall it hangs on. People choose the format from what they know off an online shop, not from the space the picture is going into. The result feels tentative — as though the wall had swallowed it.
In this guide we go through choosing the format practically: by the wall, by the furniture beneath, by the subject, and by the resolution your photograph can carry.
Measure the wall, not the canvas
Start with the space. Take a tape measure and measure the free area of wall where the picture will go — not the whole room, just the part the picture is meant to fill.
A rule that holds: the picture, or the group of pictures, should take up roughly two thirds of the width of the furniture it hangs above. Over a 200 cm sofa that puts you at around 130 to 150 cm. Over a 120 cm sideboard, reckon on about 80 cm.
On a free wall with no furniture it is more about the proportion of the whole surface. Here the larger format almost always looks more confident than the smaller one. If you are torn between two sizes, take the larger — an undersized picture is a far more common mistake than an oversized one.
Orientation follows the subject
Canvas is printed portrait, landscape or square, and that choice should be driven by the subject, not by the shape of the wall.
Landscapes, panoramas and travel photographs work in landscape — the format follows how the eye took the scene in. Portraits, architecture and images with a strong vertical belong in portrait. Square suits a detail, a still life, or when you want a neutral, calm format for a modern interior.
Watch the crop. If your photograph has a different aspect ratio from the target format, something has to go. Think ahead about what you can afford to lose at the edges and what you certainly cannot. If you are unsure, send us the photograph — we will show you how the crop will look before anything is printed.
How much resolution a format needs
This is the part online shops like to skip. Not every photograph can be printed at every size. The bigger the format, the more pixels it needs to stay sharp.
As a guide: a photograph from an ordinary twelve-megapixel phone prints well up to roughly 60×80 cm. For a canvas a metre and over you want a shot from a better camera or a professional scan. Old, small or heavily compressed images from the internet have too few pixels — at a large format they soften and break up into grain.
Canvas is more forgiving of resolution than glossy photo paper — the texture of the fabric and the greater viewing distance hide some of the softness. Even so: better one size down and sharp than large and blurred. Send us the photograph and we will tell you straight away what size is worth printing.
Small, medium, large — what goes where
Small formats up to about 40×40 cm work on a shelf, on a desk, or as part of a gallery wall made up of several pieces. Don't put them alone on a large wall.
Medium formats around 50×70 or 60×90 cm are the most versatile. They sit well above a sideboard, in a bedroom, in a hallway — most domestic commissions land right here.
Large formats above 90 cm and panoramas over a metre turn the picture into the dominant feature of the room. Here it is worth considering a frame — a large picture in a frame reads as intent, not as a photograph hung on a wall. We print canvases over two metres as well; at those sizes we always discuss the resolution of the source first.
When you are not sure
Choosing a format is hard to do from a desk. It helps to try the size physically — cut a rectangle at the size you have in mind out of paper or newspaper and tape it to the wall. Look at it for a few days. Most people find they want to go one size up.
The other option is our configurator at rdhramy.cz — you enter the dimensions and the frame type and see a live preview. And if you want certainty, send us the photograph with your enquiry; we will recommend a format based on the resolution and on where the picture is going.
