Restaurant Menu QR Code: Size, Glare and Web Menu vs PDF
A menu QR code is a link code judged by a hungry guest in bad light. The technical part is trivial; the failure modes are physical. A code that is too small, printed on gloss, or hidden behind a candle will be ignored even if it decodes perfectly on a desk.
Web menu or PDF?
A web menu wins on almost every count: it reflows to a phone screen, updates without reprinting, can carry prices and allergen notes as text, and works with screen readers. A PDF preserves a designed layout but forces pinch-zoom, panning and a download on a slow connection. Keep a PDF only if the menu is a designed artefact guests expect to keep.
- Web menu: fast, readable, updatable, and measurable.
- PDF: layout fidelity, but a poor fit for a 6-inch screen and slow mobile networks.
- Never require an app or a login to read the menu.
- Put the menu URL on your own domain so a platform change does not break every table card.
Size, lamination and glare
Print the code at 30–40 mm square for a table tent and keep the quiet zone clear. Use matte lamination or uncoated card: gloss reflects ceiling lights and windows, and a phone camera sees a white rectangle instead of modules. Avoid printing white modules on a dark background unless you test it — many cameras handle inverted codes, but not all scanners do.
Placement on the table
Put the code where the guest already looks: the condiment caddy, the table tent, the bill folder. Keep it off the underside of a sticky menu sleeve. At a counter, place it at eye level rather than flat on the surface, and add a one-line instruction in plain language — “Scan for the menu” — instead of relying on the symbol alone. If you print in house, the studio’s folded table-tent template lays out two mirrored panels on A4 landscape, so the code faces both sides of the table.
Updating a menu without reprinting
A static code freezes the URL, not the content. Update prices and seasonal items on the page and every printed card follows. If you change the domain or the path, every card must be reprinted; that is the moment to move to a stable short path you control and keep it for years.
Frequently asked questions
How big should a table menu QR code be?
At least 30 mm square for a table tent, 40 mm if the table is wide or the lighting is dim. Bigger is safer than denser.
Does lamination hurt scanning?
Gloss lamination can. Matte film or uncoated card avoids the mirror reflection that hides the modules under a ceiling light.
Can I change the menu without reprinting the code?
Yes, if the code points at a URL whose content you control. Changing the URL itself always requires a reprint.
