For a custom photo puzzle, the image’s pixel dimensions matter separately from the finished puzzle size. A large print label or a changed DPI setting does not by itself add detail to a small original photograph.
The Ravensburger US service FAQ specifies JPEG files in RGB, between 3 and 19 MB. Its recommended image dimensions are 1890 × 1400 pixels for 100-, 300- and 500-piece options, and 2646 × 1890 for 1000 pieces. This guidance concerns that US custom service, not every retail puzzle or regional ordering platform.
| Field to record | What it tells you |
|---|---|
| Original pixels | How much image information starts the process |
| File type and colour mode | Whether the upload meets the service specification |
| Final crop | Which parts of the photograph remain visible |
| Finished dimensions | Whether your working surface fits |
The FAQ lists the 100-piece custom puzzle at 13.25 × 16.5 inches, with the 300-, 500- and 1000-piece options at 19.25 × 26.6 inches. Within this offering, a higher piece count does not always mean a physically larger rectangle. Check the actual option before buying a board or reserving table space.
Prepare the photograph, not just the filename
Use the original image rather than a screenshot from a messaging application when you have it. Inspect the proposed crop for faces or important details near the edges. Resizing a file can change its dimensions, but cannot recover detail that the source never contained. That is our image-preparation advice, not a promise about the service’s printing results.
Also confirm that you have the rights to use the photograph. Keep a copy of the chosen original and crop so a later order is reproducible. We did not upload a personal image, place an order or evaluate print quality. Requirements read 25 October 2026; recheck the live configurator before ordering. More buying guides.
