Tips & Inspiration

A photo is right for a mosaic when the subject is sharp, recognizable and well-lit, with enough contrast and a calm background. That way your photo translates beautifully into a pixel design that you rebuild tile by tile. We convert your photo into a grid with numbered squares, and you place the colored mosaic tiles onto transparent base plates. The better your starting photo, the more recognizable the final result on your wall. Run through these 8 checkpoints and you will see at once whether your photo is ready for mosaic art.

Why your photo choice makes the difference

With mosaic art you build up an image from separate, colored tiles. Each tile works like a "pixel": up close you see little squares, from a distance they merge into a single image. Details that still look sharp on your phone screen can therefore disappear in a mosaic. No worries — you do not need a perfect studio photo, but with these 8 points in mind you will pick the photo that comes to life most beautifully. Want to know how the whole process works first? Then read how a mosaic of your own photo works.

The 8 checkpoints for the perfect mosaic photo

1. Sharpness

Always start with a sharp photo. A blurry or shaky photo will not get better in a mosaic — vague edges turn into unclear tile transitions. Zoom in on the face or main subject: if you see clear lines, you are good. Torn between two photos? Choose the sharpest.

2. Contrast

Contrast is the difference between light, dark and colors. A mosaic works with a limited number of tile colors, so your subject has to stand out clearly against its surroundings. A dark dog on a dark couch gives you little difference to work with. Photos in which the subject nicely "lifts off" the background give the crispest result.

3. A clear main subject

The most beautiful mosaics have one clear subject: a face, a pet, a beloved building or a silhouette. Photos with ten little faces or a busy holiday scene quickly become cluttered at small sizes. Ask yourself: where does my eye land first? That becomes the star of your mosaic. Do you still want to work with two people? Then choose a larger size (see point 6).

4. Light

Even, soft light is your best friend. Photos taken in daylight or in the shade have soft transitions that translate nicely into tiles. Avoid harsh flash shadows that eat away half a face, and bright backlight that turns your subject into a dark blob. An evenly lit face stays recognizable down to the very last tile.

5. Not too much fine detail

Many people underestimate this point. Because tiles are the "pixels" of your artwork, very fine details are lost: loose strands of hair, small text, jewelry or intricate patterns. Choose a photo whose shape still reads from a few meters away. Handy test: squint your eyes and look at the photo. Do you still recognize the subject? Then it works excellently as a mosaic.

6. Resolution (photo quality)

Use a photo with enough resolution: a sharp, large photo straight from your camera or phone. A small, forwarded chat image that you have to enlarge a lot simply lacks the information for a beautiful pixel design. Rule of thumb: the larger and sharper the original, the more we have to work with. So always send the original, not a screenshot of a screenshot.

7. Background

A calm background lets your subject shine. A plain wall, a sky or a soft, blurry background makes sure the tiles and colors go to your main subject instead of to a busy backdrop. If there is all kinds of stuff in the background, it competes for attention — and for tiles. Little noise in the background almost always gives the most refined mosaic.

8. Composition and crop

Finally, look at the composition: is your subject nicely in frame and not tiny in a corner? Leave some room around it, so it can still be cropped to your size. A square photo fits perfectly with 25×25 or 50×50 cm, an elongated scene suits 40×80 cm. So think ahead about which size you want and how your subject sits within it.

Quick checklist before you upload

• Sharp? Edges and face clear, no motion blur.
• High contrast? Subject lifts off the background.
• One main subject? Clear where the eye lands.
• Well-lit? Even light, no harsh shadows or backlight.
• Passes the "squint test"? Subject stays recognizable.
• Original file? Largest, sharpest version you have.
• Calm background? Little distraction.
• Good crop? Subject fills the frame, room to crop.

Does your photo not tick all eight points? No panic. Sharpness, contrast and a clear subject are the most decisive — the rest just makes it a touch more refined.

The size determines how much detail you keep

There is one more factor connected to your photo: the size. Larger sizes are built from multiple base plates, so more tiles fit and more detail is preserved. A face with finer features comes into its own better at 40×40 cm or 50×50 cm than at 25×25 cm.

Curious how the building itself goes?

Have you chosen your photo? Then the rest is wonderfully relaxing: no paint, no needle, no thread — you simply place the tiles on the numbered grid. In our beginner's guide you will read how to read the grid, and in what is mosaic art with tiles you will discover how it differs from diamond painting. Still torn between our hobbies?

Frequently asked questions

Can I use an old or slightly blurry photo?

An old photo certainly works, as long as the subject is recognizable and reasonably sharp. A slightly blurry photo will not get sharper in a mosaic, so choose the sharpest version where possible. Only have a somewhat vague photo of a cherished memory? Then choose a larger size and a simple, clear subject — that is the most forgiving.

Does a group photo or a photo with several people work?

It can, but keep in mind that small faces quickly lose detail in tiles. For two people it is best to choose a larger size such as 40×40 cm or 50×50 cm. For a large group we recommend a photo with fewer people or a wider crop, so each face gets enough tiles.

Do I have to crop or edit my photo myself?

You do not have to. We convert your photo into a personal pixel design and take care of the right crop for the size you choose. Would you like to indicate a crop yourself in which your subject is nicely framed? That helps, but it is not a requirement.

Which size gives the most detail?

The larger the size, the more tiles and therefore the more detail. Larger formats are built from multiple base plates. For a face or finer subject we recommend at least 40×40 cm. You will find all sizes and prices in our guide to prices and sizes.

Can I use a screenshot or a photo from the internet?

Preferably not. Screenshots and internet images often have a low resolution, which makes the pixel design less sharp. Also, only use photos you own the rights to. The original from your own camera or phone always gives the best result.

What if my photo does not meet all the checkpoints?

No worries — almost no photo scores a perfect eight out of eight. The most important points are sharpness, contrast and a clear main subject. If your photo meets those, you are good. In doubt? Choose the best photo you have and we will turn it into a beautiful mosaic design.
