Turn a Photo into a
Paint by Numbers Template

A paint-by-numbers template is a photograph with all of its gradients thrown away. Every soft transition has to become a hard edge between two flat colors, which means the subjects that survive are the ones that were already built out of shapes: a pet or a portrait framed tightly, a flower, a building, a landscape with a strong horizon, a bold graphic. What struggles is anything whose interest lives in fine texture — a crowd, a forest canopy, a lace pattern — because the generator has to either give each speck its own region, which is unpaintable, or merge them away, which erases the thing you liked about the photo.

The color count is the main lever and the one most people set too high. At 24 — the default here, and the smallest palette a boxed kit ships with — a face still reads as a face and each number is one pot of paint you can buy or mix. At 36, the cap, you get more tonal steps but a key page that takes real bookkeeping to work through. Below about 10, the result stops being a copy of the photograph and starts being a poster of it, which is often the better-looking outcome for a bold subject.

Print size matters more than it looks like it should. Every rule this generator applies — the smallest region, the width of the outline, whether a number fits — is expressed in millimetres at the finished size, so choosing A3 instead of A4 does not just print the same template larger: it lets smaller regions survive, and the template genuinely holds more detail. If you plan to paint on a canvas, export the SVG and take the real size with you rather than enlarging a printed sheet.

Paint by numbers and color by numbers describe the same thing — a picture split into numbered regions — and people use the two phrases interchangeably. The only practical difference is what is in your hand. Color by numbers usually means pencils or markers on paper, so a template printed at home is the whole product. Paint by numbers usually means acrylics on canvas, which is why the SVG export matters: the outlines have to be transferred or printed onto the canvas at full size before you start.

A custom kit is the other way of getting here: you send a photo to a seller and a stretched canvas, printed outlines, numbered paint pots and brushes arrive in the post, usually for somewhere between twenty and sixty pounds or dollars. That is a good deal if you want the paints chosen and measured for you. This page is the free half of it: you get the same template — arguably a more honest one, since you can see the result and change the color count before committing — and you buy or already own the paint.

Printing at home is the usual route. The PDF tiles the template across as many sheets as it needs with an overlap margin to tape along, so an A4 printer can still produce a poster-sized template. For canvas, the SVG opens in any vector program and can be printed or plotted at the exact size of the canvas you bought.
