Printable Mandala Colouring Pages
Generate a random symmetric mandala to colour in — three detail levels and an endless supply, all free.
Each mandala is drawn fresh in your browser from concentric rings of petals, scallops, diamonds and dots repeated in perfect radial symmetry. Press Regenerate and you'll never get the same design twice — ideal for calm-down corners, party activity packs, or a mindful colouring break for grown-ups.
Choose Simple for young children (big, bold shapes), Medium for a balanced page, or Complex for an intricate adult colouring design. Everything prints as clean black outlines ready for pencils, textas or gel pens.
Printing at exact scale
Every sheet is drawn in real millimetres and prints at exact physical scale. For accurate output, set Scale = 100% (Actual size) and Margins = None in your browser's print dialog. Not sure your printer is honest? Run the printer ruler test first to confirm 50 mm really measures 50 mm.
Frequently asked questions
How do I get a different mandala?
Click the Regenerate button. Each click builds a completely new random design at the detail level you've chosen.
Are these good for adults too?
Yes — choose the Complex detail level for an intricate, meditative adult colouring page.
Can I change the outline colour?
Yes, but black or dark grey prints best and is easiest to colour inside.
Is it really free?
Yes. Every template on printsheet.io is completely free, with no sign-up, no account and no watermark. Generate as many sheets as you like.
How do I get an exact-scale print?
Choose your paper size, then in the print dialog set Scale to 100% or “Actual size” and Margins to None. The sheet is defined in real millimetres, so it prints at true size. Use the calibration ruler page to verify.
Which paper sizes are supported?
A4, A5, A3, A6, US Letter, Legal and Tabloid, in portrait or landscape. Pick the size that matches the paper loaded in your printer.
Can I save it as a PDF instead of printing?
Yes — choose “Save as PDF” as the printer in your browser's print dialog. The PDF keeps the exact millimetre dimensions.
