Perler bead QR code pattern maker
Type a link, a message or your Wi-Fi details and get a fuse bead QR code that phones can scan, with Perler, Hama or Artkal colours, bead counts and pegboard sizes.
How to make a bead QR code
- Make the pattern above and scan it on screen first.
- Fill every peg. Black for dark squares, white for light squares and the border. Holes confuse phone cameras.
- Iron evenly on both sides, then cool it under a book so it stays flat.
- Scan it in good light. Matte fused beads scan better than glossy ones, so iron until the shine goes.

Questions
Does a Perler bead QR code scan?
Yes. Fused black and white beads scan very well. Iron evenly so every bead keeps its shape, and keep the white border of 4 beads all round.
Will it fit on one pegboard?
A very short text (up to about 14 characters) makes a code of exactly 29 × 29 beads including its border: one large square pegboard. A typical short link is 33 to 37 beads, so it needs 4 boards, or use the 2-square border option to fit a little more.
Which bead colours should I use?
Black and white give the best contrast. The pattern maker picks the darkest and lightest beads in your brand (Perler, Hama or Artkal) and gives the bead count for each.
Do I need white beads for the light squares?
Yes. Empty pegs leave holes, which phones read as random dark spots. Fill every square, including the border.
Is it free?
Yes. Bead QR code patterns up to 80 × 80 beads download free with bead counts and a printable chart.
