Which Photos Make a Good Jigsaw Puzzle (And Which Don't)

Most photographs that look good on a phone make disappointing puzzles, and the reason is simple: a puzzle is not judged on how it looks finished. It is judged on the two hours spent getting there.

The rule: detail spread evenly

A good puzzle photo has visual information in every part of the frame. What makes a section miserable is not difficulty — it is a lack of anything to reason about. Twenty pieces of identical blue sky are not a challenge, they are a chore done by shape alone.

Works well: busy street scenes, cluttered rooms, groups of people, markets, bookshelves, detailed landscapes with foreground interest, pets against textured backgrounds.

Works badly: portraits on plain studio backgrounds, beach horizons, snow, night skies, anything with a large blurred bokeh background, heavily filtered images where shadows have crushed to black.

The compromise most people actually want

The photograph that means something is usually a portrait — and portraits are exactly the shape that puzzles badly. There are three ways round it:

1. Choose a lower piece count. A portrait at 100 or 300 pieces is enjoyable. The same image at

1000 is punishing.

1. Pick the version with background in it. The wider shot you rejected because it was "too

busy" is the better puzzle.

1. Use a collage. Several photos in one frame gives the eye landmarks everywhere.

Resolution: what you actually need

Print quality is measured in DPI — dots per inch — at the finished size. Below about 150 DPI the image starts to look soft, and it shows most at the cut edges of pieces.

As a rough guide for our sizes:

| Piece count | Finished size | Minimum sensible photo | |-------------|---------------|------------------------| | 100 | small | 6 MP (most phones since ~2012) | | 300 | medium | 8 MP | | 500 | 480 × 340 mm | 12 MP | | 1000 | large | 16 MP or a good 12 MP original |

Two things quietly destroy resolution: screenshots (already downsampled) and images sent through messaging apps, which recompress hard. Always start from the original file in your camera roll, not the copy someone sent you.

We check this automatically. Upload a photo and you are told the largest piece count it can carry before you can order anything — we will not sell you a size your image cannot hold, and we never upscale by more than 2×.

Test it before you buy it

The advantage of a puzzle you can play in the browser is that this whole article becomes unnecessary. Upload the photo, play it at the piece count you are considering, and you will know within five minutes whether that sky is going to be a problem. Then order the printed one, or don't.
