Image & Photo
Grid layouts with spacing, background and rounded corners.
A collage with no gaps reads as one confusing image, because the eye cannot find the boundaries between photographs.
A consistent gutter — roughly 1–2% of the canvas width — separates them enough to be read individually while still reading as one composition.
Consistency matters more than the exact size. Equal gutters everywhere, including the outer margin, is what makes a grid look deliberate rather than assembled.
Photos of different shapes in a uniform grid must be cropped, stretched or letterboxed. Only one of those is acceptable.
Cropping to fill loses edges but keeps everything looking right. Stretching distorts faces and is always visible. Letterboxing preserves everything and leaves inconsistent bands of background.
Crop to fill by default, and check each cell afterwards — automatic centre-cropping frequently cuts the subject out of a photo that was composed off-centre.
Set the output to the largest dimension you might need. A collage exported at screen size cannot be printed later, and re-making it means finding all the source images again.
For print, work back from 300 DPI at the physical size: an A4 collage needs roughly 2,480 × 3,508 pixels.
Bear in mind that a collage is only as sharp as its smallest source image. One low-resolution photo in a high-resolution grid is visible immediately, and no export setting fixes it.

A collage is only as sharp as its lowest-resolution source. One small image in a large grid is immediately visible, and no export setting can recover detail that was never captured.
No. The collage is composed on a canvas in your browser and downloaded from there — which also means there is no file-size limit imposed by an upload.
