Is this diamond painting pattern generator free?

Yes. 1 upload, generation, and full browser preview and all of its edits are free, with no account required. A $2.99 single-pattern unlock gives you the PNG and printable PDF. Pro ($6.99/month or $59.99/year) unlocks unlimited projects, every export, larger grids for statement pieces, and every other craft generator.

How do I order the right drill colors?

The PDF legend lists DMC codes for each color (e.g., DMC 310 = Black). Search Amazon for 'diamond painting drills DMC 310' or order from specialty sites like DiamondDrillsUSA or AliExpress. DMC is the universal standard — any supplier's DMC 310 will match any other supplier's DMC 310. Order 20% more drills than estimated to account for waste and defects.

Round or square drills?

Round: easier to place, forgiving of slight misalignment, visible gaps between drills. Best for beginners and large projects. Square: complete coverage, sharp mosaic look, requires precise placement. Best for display pieces and geometric designs. Both use the same DMC codes and pattern chart.

How big will my diamond painting be?

A standard drill is 2.5 mm, so a canvas holds 4 drills per centimeter (about 10 per inch). Drills across ÷ 4 = width in cm. Examples: 80×120 drills = 20×30 cm (8×12 inches). 120×160 = 30×40 cm (12×16 inches, a popular display size). 160×200 = 40×50 cm (16×20 inches, a large statement piece). Most suppliers sell blank adhesive canvas in these standard sizes.

How much does a DIY custom diamond painting cost?

Adhesive canvas: $5-10 (size dependent). DMC drills: $0.50-1.00 per bag of 200, typically 15-20 bags needed = $8-15. Applicator pen, wax, tray: $3-5 (or reuse from a previous kit). Total: $15-30. Compare to $50-150+ for a commercial custom kit. You save 60-80% and get exact color control.

Why is confetti reduction so important for diamond painting?

Each confetti drill (isolated single-color placement) requires: locating the correct bag from 20+ bags, opening it, loading the pen, placing exactly one drill, then switching to a different bag. With 500 confetti drills across 25 colors, that's thousands of bag-switching actions. ArtPatt's Heavy confetti filter replaces isolated drills with the surrounding majority color. Under 2% confetti = a relaxing, enjoyable painting experience.

What photos work best?

Close-up portraits with simple backgrounds, bold graphic designs, pets with clear lighting, landscapes with distinct foreground/sky separation. Avoid: group photos (faces too small at 10-count), busy detailed backgrounds, very dark images, photos with hundreds of subtle color gradients. Boost brightness and contrast in preprocessing for best results.

Is diamond painting good for detailed portraits?

Yes, but only if the face is large in frame and the canvas is big enough to carry it. At the fixed 10-count density, a face needs roughly 90 drills across before subtle features stay readable — below that, portraits come out muddy no matter how many DMC colors you allow. Crop tight on the subject and size the canvas to the face, not to the wall you want to fill.

Is this the same as a diamond painting pattern maker?

Yes — "diamond painting generator" and "diamond painting pattern maker" describe the same tool. Upload a photo, set the canvas size and DMC color count, and ArtPatt builds a drill-by-drill chart with a DMC legend, exactly like a dedicated pattern maker would. Making and editing the chart is free; the printable PDF is a one-time unlock or part of Pro.

How it works

Upload a photo

A close-up with a plain background works best. Faces and pets should fill the frame.

Set size and colors

Pick the canvas size and a DMC color count — 15 to 25 suits most pictures.

Clear the confetti

Heavy confetti reduction merges lone drills into their neighbours, so you switch bags less.

Print and order drills

The chart lists every DMC code with how many bags to buy.

Diamond Painting Canvas Sizes

A standard drill is 2.5 mm, so every centimeter of canvas holds 4 drills. These are ArtPatt charts of the same photo at each size — the bigger the canvas, the more detail the face keeps.

20 × 30 cm · 8 × 12 in
80 × 120 drills — pets, logos, bold graphics
30 × 40 cm · 12 × 16 in
120 × 160 drills — most portraits
40 × 50 cm · 16 × 20 in
160 × 200 drills — detailed faces, wall pieces

20 × 30 cm: 80 × 120 drills — pets, logos, bold graphics
30 × 40 cm: 120 × 160 drills — most portraits
40 × 50 cm: 160 × 200 drills — detailed faces, wall pieces

A face needs about 90 drills across to stay recognizable, so size the canvas to the face, not the wall. For any other size, use the diamond painting size calculator.

Round vs Square Drills

The same chart, placed with each drill shape. Both use the same DMC codes — you choose the shape when you order.

Round drills

Sparkly finish with small gaps
Forgiving and easy to pick up
Best for beginners and large canvases

Square drills

Solid mosaic finish, no gaps
Need careful alignment
Best for display pieces and sharp graphics
