Diamond Painting Size Chart & Calculator
Diamond Painting Calculator
Calculate the estimated time for your next diamond painting project before choosing a size or uploading your photo.
This diamond painting size chart and calculator helps you choose the right canvas before ordering. It estimates drill count, working time and the best size for beginners, portraits, pets, couples, group photos and larger wall pieces.
The guide is cm-first for EU and UK shoppers, with inches included where helpful. For custom photos, size matters because every face, eye, pet detail and background edge has to be translated into small drills.
Diamond painting size chart
| Size | Best for | Typical time | Notes |
|---|---|---|---|
| 20x20 cm / 8x8 in | tiny practice pieces, kids, quick tests | 4-12 hours | choose a very simple image |
| 30x40 cm / 12x16 in | beginner-friendly single-subject kits | 10-30 hours | not ideal for detailed custom portraits |
| 40x50 cm / 16x20 in | best all-round adult size, pets and faces | 20-50 hours | good balance of detail and effort |
| 50x70 cm / 20x28 in | couples, detailed pets, meaningful gifts | 40-90 hours | much clearer than small sizes |
| 60x80 cm+ / 24x32 in+ | groups, landscapes, statement wall art | 70+ hours | best for high detail and patient crafters |
Best size by photo type
For one clear face or one pet, 40x50 cm is usually the safest starting point. For two people, a detailed pet photo or an important gift, 50x70 cm gives the image more room. For families, groups, landscapes and photos with several small subjects, start at 60x80 cm if the final result matters more than speed.
A useful rule: the smaller the main subject appears in the original photo, the larger the finished diamond painting should be. If you are unsure, use the custom diamond painting editor to preview your photo before ordering.
Beginner size vs photo-result size
The easiest beginner size is not always the best custom-photo size. A 30x40 cm kit is manageable and satisfying for a first project, but a family photo or detailed portrait can look too compressed at that size.
If you mainly want to practise, choose a simple kit from the diamond painting collection. If the picture is personal or intended as a gift, give the details more space.
Round vs square drills and size
Square drills are denser and can create a very neat mosaic finish, especially on larger canvases. They take more care to align. Round drills are faster and more forgiving, which makes them more comfortable for first projects and casual evening crafting.
For a large, detailed canvas, square drills can look especially tidy. For a relaxed first project, round drills are usually the easier choice.
How to use the calculator
Enter width, height, drill shape, detail level and your weekly working time. The calculator estimates drill count and hours. Treat the result as a planning tool, not a promise, because everyone works at a slightly different rhythm.
For a custom photo, pair this estimate with the photo and size guide for custom diamond painting. If your main question is time, read how long a diamond painting takes by size.
Frequently Asked Questions
What size diamond painting should I choose?
Choose 30x40 cm for a simple first project, 40x50 cm for the best all-round adult size, and 50x70 cm or larger for detailed photos, portraits, pets, couples and statement pieces.
Is 30x40 cm big enough for a diamond painting?
30x40 cm is big enough for a simple design with one clear subject. It is often too small for detailed portraits, group photos or images where the main subject takes up only a small part of the picture.
How many drills are in a 40x50 cm diamond painting?
A 40x50 cm full-drill canvas has roughly 25,500 round drills or 32,000 square drills before manufacturer, border and partial-drill differences.
How long does a 40x50 cm diamond painting take?
A 40x50 cm diamond painting often takes about 20-50 hours depending on drill shape, detail level and your working pace. Use the calculator for a more personal estimate.
Can I preview my photo before ordering?
Yes. The custom diamond painting editor lets you upload a photo, test different sizes and preview the result before ordering, which is more reliable than guessing from a static size chart.
