QR code board: shop signs, notice boards and bulletin boards

A QR code board is a printed sign with a code that opens a link — a shop window, an office notice board, a classroom bulletin board. The code is the shortcut; the board is the context. Here is how to size it, place it and print it so people actually scan it.

Where a QR code board works

The board does the explaining; the code does the hand-off. That is why the line next to the code matters as much as the code itself: "Scan for today's menu" removes the guesswork.

• Shop window or A-board — menu, reviews, offers, booking page.
• Office, building or community notice board — forms, documents, timetables, event pages.
• Classroom bulletin board — reading lists, quizzes, resources and links for parents.

Shop signs and A-boards

A code on a shop window is scanned from 1-2 metres, so it needs to be 10-20 cm wide — much larger than the version people print for a business card. Put it at eye level (1.2-1.6 m), on matte material, and test it from the pavement in the light you actually have.

If the link may change — a seasonal menu, a campaign page, a booking form — use a dynamic QR code so the printed board never has to be remade.

Notice boards: office, building and community

A notice board often carries several items. Two layouts work: one hub code in the corner that opens an index page, or one code per item, placed next to the thing it belongs to. The second is clearer for visitors but means more codes to print and test.

Keep each code at least a few centimetres away from other codes and from the edge of the board. A wall of near-identical squares is hard to aim at; a short label under each one fixes that.

Classroom bulletin boards

For teachers the useful pattern is a code next to a specific item — a reading list, a quiz, a permission form — rather than one code for the whole board. Print at 3-5 cm for a board read at arm's length, laminate matte rather than gloss, and test with the devices students actually use.

Static or dynamic?

If the destination will never change and you do not need scan counts, a static code is free and cannot expire. If the board stays up while the link changes — menus, timetables, campaigns — a dynamic code lets you update the destination without reprinting. The full comparison is in static vs dynamic.

Size and print checklist

• 1 cm of code per 10 cm of scanning distance — business card ~2 cm, table tent ~4 cm, shop window 10-20 cm, poster 30 cm+.
• Dark modules on a light background; keep the four-module quiet zone clear.
• Matte finish — gloss laminate reflects light and is a common cause of failed scans.
• Print one proof at final size and scan it in the place it will live.
• Place at 1.2-1.6 m for standing adults; add one plain-language instruction.
• More detail in the QR code printing guide.

Common mistakes

• Code printed too small for the distance people scan from.
• Low contrast or an inverted colour scheme that only some phones accept.
• Quiet zone cropped by the designer or covered by text.
• Code wrapped around a curve, folded, or placed behind reflective glass.
• No instruction line, so visitors do not know what the code does.
• A broken or outdated link — test the destination, not just the pattern.
