To turn a picture into a paint by numbers canvas you need two things: a photo with clear shapes and good light, and a way to convert it. That conversion can be free software that hands you a printable template, or a made-to-order kit that arrives with the canvas and the paints already matched to your image.
Both routes work, and they give you very different things. Most of the confusion around this topic comes from guides that describe one route and quietly price the other. This one covers choosing the photo, what each route actually gets you, and how to paint the result once you have it.
Worth saying plainly: Ledgebay makes custom paint by numbers kits from customer photos, so we have an interest in one of these answers. The free route is covered honestly below regardless, because for some people it is the better one.
Choose a photo that converts well
This step decides everything that follows, and it is the one people rush. Any conversion, free or paid, reduces a photograph to flat areas of a single color. Detail that depends on subtle gradation simply disappears. The photos that survive that are the ones that already read clearly as shapes.
What to look for:
- Good light. Bright daylight converts far better than a dim indoor shot. Low light gives you a range of similar mid-tones that all resolve to the same two or three numbers, and the result looks muddy.
- The subject large in the frame. A face from the shoulders up, not a full-length figure across a room. Anything small in the original becomes a cluster of tiny sections that are difficult to paint and hard to read.
- Separation between subject and background. A dog against a plain wall converts cleanly. The same dog in long grass of a similar color does not.
- Fewer faces, or a larger canvas. Two or three people on a small canvas gets tight quickly. Each face needs enough sections to look like that particular person rather than a person in general.
What tends not to work: heavy backlighting, motion blur, busy patterned backgrounds, and images already cropped so tightly there is nothing left to trim.
The two ways to do it
Free conversion software
Tools such as PBNify and Mimi Panda take an uploaded image and return a numbered outline with a suggested palette. They cost nothing and they are genuinely interesting to experiment with. We have written separately about what PBNify does well and where it struggles, and a broader look at the conversion tools worth trying.
Be clear about what you end up holding, though: a template, and nothing else. You still have to print it at a size worth painting, get it onto a surface that will take paint, and then mix every numbered color yourself from tubes you buy separately.
That last part is where most people stop. A conversion might call for thirty distinct colors, and matching thirty acrylic mixes by eye against a screen is a real skill that takes practice. The template is the easy half of the job.
It is a sound route if you already paint, already own a reasonable range of paint, and want the outline as a starting point rather than a finished plan.
A made-to-order kit
The other route is to have the conversion, the canvas and the paint set produced together. You choose a size, upload your photo, and what arrives is ready to paint: the numbered canvas, a paint set mixed to your image, brushes, and a printed color reference of your own photograph to work from.
Ledgebay's Custom Paint by Numbers comes in 12x16, 16x20 and 18x24, framed or unframed. It is printed and shipped in the USA rather than drop-shipped from overseas, which is the main reason it arrives in a reasonable window. If you are unsure whether a particular photo will convert well, send it over before ordering and you will get an honest answer.
Choose the 18x24 if there is more than one face in the picture. The extra size is less about wall presence than about giving every face enough sections to be recognizable.
What comes in a custom kit
- Your photo printed as a numbered cotton canvas, pre-primed so the paint sits on the surface instead of soaking in
- An acrylic paint set mixed to match your image, vacuum-sealed so it arrives wet rather than half dried
- Brushes in a range of sizes
- Printed instructions and a color reference of your own photograph
- Framed sizes arrive pre-stretched on a wooden frame with a small tabletop easel. Unframed sizes do not include the easel
Paint by numbers kits use soft body acrylic. Not oil, not watercolor. It levels flat, covers the printed numbers in a coat or two, and cleans up with water. You will find guides offering oil paint as an alternative for this kind of project — it is bad advice. Oil dries far too slowly for sectioned painting and does not behave well on a pre-primed kit canvas.
Painting it
Work dark to light
Start with the darkest colors and move toward the lightest. Darks cover the printed numbers in a single coat, so the canvas tidies up early and you get a sense of the image quickly. Pale colors often need two coats, and light paint straying into a dark section is easy to cover afterward. The reverse is not true.
Thin, even coats beat one thick one. Laying paint on heavily leaves ridges that catch the light and never quite settle, and it does not hide the numbers any better. If a pale color still shows the number underneath, let it dry properly and go over it again.
One trick worth knowing: shading a printed number with a white colored pencil before you paint over it lets pale colors cover in one coat instead of three. There is more in our guide for beginners.
Matching and mixing
With a kit, the colors are already mixed for you and numbered to match, so there is nothing to match by eye. Keep the pots closed between sessions and stir before use.
If you are working from a free template and mixing your own, remember that acrylic dries slightly darker than it looks wet — the binder is milky in the pot and clear once cured. Judge every match after it has dried, not while it is still on the brush, or the whole painting will end up a shade heavier than you intended.
If something goes wrong
Paint that has thickened in the pot is usually rescuable with a drop of water. Paint that has genuinely cured is not — the polymer particles have fused and no amount of water brings them back. Test with a toothpick before spending time on it.
Do not thin acrylic past roughly a quarter water by volume. Beyond that you are diluting the binder rather than the color, and the paint stops covering and can lift off the surface. And never reach for solvents. Mineral spirits, turpentine and nail polish remover all break acrylic down.
If you run short of a heavily used color, you do not have to improvise. Extra paint sets can be added to a custom order at checkout, and the stock designs have matching extra paint sets of their own.
Giving one as a gift
A custom canvas is the most-gifted thing we make, usually for a birthday, an anniversary, a retirement or a new home. It works because the picture already means something to the person opening it, which is not something a stock design can do.
Two practical notes if you are giving one. Order the framed version so there is nothing left for them to buy or work out afterward. And allow time — a custom canvas is made after you order, so it is not a same-week gift.
The honest appeal of this, for the person who ends up painting it, is not that it produces fine art. It is ten or twenty hours spent on something absorbing, a bit at a time over a few weeks, with visible progress every evening and a picture worth hanging at the end of it. You can see what that looks like in our customer gallery, which is all finished work sent in by the people who painted it.
