Receive a realistic preview, size advice and quality score per size
Our tool converts your photo into a realistic diamond painting simulation. You upload a photo, choose the desired width in centimetres and the drill type, and within seconds you see the result. The generator takes into account the number of drills per centimetre, the colour reduction inherent to diamond painting, and the pixel density of your chosen size.
In addition to the preview, you automatically receive size advice. The tool analyses the complexity of your photo and calculates at which size your photo is shown to best effect. You get a recommended size, a minimum acceptable size and a quality score per dimension. So you know exactly which size matches your expectations.
Calculate diamond painting size
The right diamond painting size depends on the details in your photo. A portrait needs more drills than a simple landscape. Our tool calculates the optimal size based on your specific photo.
Read more about suitable photos →Square vs. round
Square drills (2.5 mm) give a crisp mosaic result. Round drills (2.8 mm) are easier to place and give a softer effect. The preview shows the difference so you can make an informed choice.
View the grid on your photo →Quality profiles
Choose between Fast, Balanced and Max detail. Each profile weighs speed and detail retention differently. For most photos Balanced is the best choice, but for complex portraits Max detail can make the difference.
From your own photo to a custom diamond painting
More and more people want to make a diamond painting from their own photo. Whether it's a portrait of your children, a photo of your pet, a wedding photo or a favourite holiday landscape: with a custom diamond painting you turn a personal memory into a unique artwork that you make with your own hands.
Before ordering a personalised diamond painting, it's important to know how your photo looks as a mosaic of drills. Not every photo works equally well: fine details can be lost at a small size, and dark photos with little contrast often produce a less recognisable result. Our preview generator shows you this for free and instantly, so you make an informed choice before ordering.
A custom diamond painting is also a popular gift idea. With our tool you can check in advance whether the photo is suitable and which size gives the best result. This way you avoid disappointments and know for sure that your gift looks beautiful.
How many drills does my diamond painting have?
The number of drills in a diamond painting depends on the size and drill type. With square drills of 2.5 mm there are 4 drills per centimetre, i.e. 16 drills per square centimetre. With round drills of 2.8 mm there are about 3.6 per centimetre, i.e. 13 per square centimetre.
| Size | Square (2.5 mm) | Round (2.8 mm) |
|---|---|---|
| 30 x 30 cm | 14.400 | 11.700 |
| 40 x 50 cm | 32.000 | 26.000 |
| 50 x 60 cm | 48.000 | 39.000 |
| 60 x 80 cm | 76.800 | 62.400 |
| 80 x 100 cm | 128.000 | 104.000 |
A larger size means more drills and therefore more detail, but also more time to complete. A diamond painting for beginners is ideal in size 30x40 or 40x50 cm: large enough for a recognisable result, but not so large that it becomes overwhelming. Experienced diamond painters often choose 60x80 cm or larger for maximum detail.

Diamond painting tips for the best result

Photos with high contrast, bright colours and clear shapes work best. Avoid photos that are very dark or contain lots of tiny details. Check our photo tips.
Don't start too large
If you're just starting with diamond painting, choose a size of 30x40 or 40x50 cm. This way you learn the technique without the project taking months. Our tool shows which size is minimally needed.
Always compare sizes
Our preview generator shows five variants side by side. This way you can instantly see the difference in detail and quality between sizes. The quality score helps you choose the optimal size.
Use the grid tool
With our grid overlay tool you place a grid over your photo. This way you can see exactly which details are preserved and which are lost at your chosen size.
Frequently asked questions
How do I convert my photo into a diamond painting? ▾
Upload your photo via the form above, set the desired width with the slider and choose your drill type. Click "Generate layout" and you'll instantly see a preview. The tool generates five variants at different sizes so you can compare.
Can I use my own photo for diamond painting? ▾
Yes, you can use any photo. Upload a JPG or PNG and our tool instantly shows how it looks as a diamond painting. Popular choices are portraits, pets, wedding photos, holiday photos and artworks. Not every photo works equally well; use our photo tips to make the best choice.
Which diamond painting size suits my photo? ▾
That depends on the details in your photo. A portrait with fine facial features needs at least 40x50 cm, while a landscape with large colour areas can work well at 30x40 cm. Our tool calculates this automatically and gives a quality score per size.
How many drills are in a diamond painting? ▾
That depends on the size and drill type. With square drills (2.5 mm) there are 16 per cm², with round drills (2.8 mm) about 13 per cm². A 40x50 cm canvas with square drills contains about 32,000 drills. Larger sizes offer more detail but take more time.
What is the difference between square and round drills? ▾
Square drills (2.5 mm) fit seamlessly together for a crisp, mosaic-like result with maximum detail. Round drills (2.8 mm) are slightly larger, easier to place and give a softer, more organic effect. For photo details, square drills generally work better.
Which diamond painting size is suitable for beginners? ▾
For beginners we recommend a size of 30x40 cm or 40x50 cm. This is large enough for a recognisable and beautiful result, but not so large that it becomes overwhelming. Choose round drills if you're just starting out; they are easier to place. Our tool shows a quality score per size so you know what to expect.
How long does it take to make a diamond painting? ▾
The time depends on the size, number of colours and your experience. A small 30x30 cm canvas takes an average of 8-15 hours. A medium 40x50 cm canvas takes 20-40 hours. Large canvases of 60x80 cm or more can take 60-100+ hours. Most people work on it as a relaxing hobby, a few hours at a time.
Is the tool free to use? ▾
Yes, the Diamond Painting Preview Generator is completely free. You can upload unlimited photos and generate previews. No account needed. For webshop owners who want to integrate the preview functionality, we offer a B2B API.
