Photo dimensions & file-size quick reference

Dimensions are width × height in pixels. Suggested file sizes are compression targets, not platform limits.

Need another shape? Crop first, then resize and compress. Keep your original; do not sacrifice detail just to reach a suggested target. JPG is usually suitable for photos. Etsy does not preserve PNG transparency.

2

3

Download

Understand your resize settings

Pixel dimensions control how large an image is. File size measures its bytes and also depends on the format, quality and image content.

Image resizer diagram: 1200 by 800 pixels becomes 600 by 400 pixels, keeping the same 3:2 proportions.
Halving both dimensions leaves one quarter of the original pixels. Keep the aspect ratio locked to avoid stretching.
Image resizer workflow: choose an image, set dimensions with the aspect ratio locked, then inspect and download the result.
Choose dimensions first, then inspect the export. If an upload form imposes a byte limit, compress the result and check readability again.
