Paste your link and see it sprayed on concrete. Point your phone at the preview: if it scans here, it will scan on the wall. Pick a size, and we bridge every square so nothing falls out.
Yes. Phones read QR codes by contrast, and a code has plenty of built-in redundancy: we make every stencil at the highest error-correction level, so a smudge, a chip or a bit of overspray still reads. The preview on this page is drawn the way paint lands on concrete; point your phone at it and see. When a painted code doesn’t scan, the usual causes are a low-contrast colour, a very rough surface, or a stencil taped down backwards.
Yes, with the same stencil. Modern phone cameras read light-on-dark codes as well as dark-on-light, so paint whatever colour you like as long as it contrasts with the surface. If you want the classic look on a dark wall, paint a light square first and stencil the code on top.
No. The code holds your link directly, so there’s no redirect service in the middle to pay for or to shut down. It works for as long as your link does. Paint lasts for years, so point it at a page you control — then you can change what that page says without repainting.
Every character adds squares to the code. A long link makes a dense code, and at a small size the squares get too fine to cut cleanly and too easy to clog with paint. Make the stencil bigger, or use a shorter link — a short path on your own website is best.
A phone reads a code from about ten times its width: a 12″ code from about ten feet, a 24″ code from about twenty. For a sidewalk or a wall people walk past, go bigger than you think.
Any light square that’s surrounded by dark ones would fall out of the sheet. Where two light squares meet only at a corner, we widen that point into a small diagonal neck. Everything else is held by thin, straight bridges that run along the edges of the squares, at opposite corners so nothing twists, and never across the middle of a square, which is where a phone reads. The three corner blocks get a fixed set of four.

Yes. Order it and we cut it on reusable mylar and ship it. You see the price before you add it to your cart, and the size and link you chose are exactly what we cut.
