String art generator

In short: Upload a portrait and the generator works out a single continuous thread path around a ring of pins (120–300 nails) that recreates the picture. You get a live preview, the numbered pin-to-pin sequence to follow, the number of lines and the thread length for your board size. Free: unlimited on-screen patterns, colour key, materials list and PNG chart download. PDFs up to 60×60 are always free, plus your first full-size PDF; after that a larger print-ready PDF is $2.99 per photo, or $7.99 for 30 days of unlimited PDFs.

How it works

  2. Choose pins (200 is a good start) and lines (2,000–4,000).
  3. Download the pin sequence and wrap the thread in order.

Getting a good result

Use a bright, evenly lit face against a plain background and crop to a square. More lines give darker, more detailed results but need more thread — about 1–2 km for a 50 cm board at 3,000 lines.

FAQ

How does a string art generator work?

It starts at pin 0 and repeatedly picks the next pin whose straight line covers the most remaining dark area of the photo, then lightens that line. The list of pins is your wrapping order.
