A wedding photograph can work beautifully on canvas, but the crop needs as much thought as the size. Start by deciding what the picture is about: the two of you, a whole group or the atmosphere of the place.
Use the photographer’s high-resolution file intended for printing, where your agreement permits it. A gallery screenshot or small social-media download may not contain the same detail. If several versions are available, check which is the full-resolution copy before uploading.
Match the shape to the picture
A wide group photograph usually needs a different shape from a close portrait. Forcing a wide picture into a square may remove guests at the edges. A tall crop can also cut away part of a dress or the setting that gives the photograph its character.
For a specific example, turning a 3:2 landscape photo into a square by cropping only the width removes one-third of its original width in total. That can be a substantial amount of the scene. Preview the actual photograph rather than choosing a square simply because it fits a space on the wall.
Inspect more than faces
Check hands, bouquets, veils and the bottom of outfits. Look for architectural lines that appear tilted. Then review the canvas sides: an edge that looks acceptable on a flat photograph may be distracting once part of the picture wraps around the frame.
For group photographs, enlarge the preview to inspect the people at both ends. A small thumbnail can conceal a clipped shoulder or a face pushed too close to a side.
Make the wall test
Mark the proposed dimensions with paper before ordering. View it from the doorway and your usual seat. For a collection, consider a main portrait with smaller supporting moments rather than making every image compete at the same size.
You do not need to crop tightly just because the faces are the focus. Space around a couple can be part of the photograph’s appeal. Choose a photo canvas size that lets the whole composition work.
