QR codes for schools and universities
Education QR codes work best on noticeboards, in printed handouts and on library shelving. The constraint most schools miss is that many students have no data allowance — so linked resources must be light, and a printed alternative must exist.
Assume no data
A meaningful share of students have limited or no mobile data. Design accordingly:
- Keep linked pages under 500 KB, images optimised, no video autoplay.
- Provide school WiFi details on a WiFi code next to the resource code.
- Never make a QR code the only route to homework, safeguarding information or exam details.
Where they work
| Use | Placement |
|---|---|
| Homework and resource links | Printed worksheets |
| Library shelf guides | Shelf ends, by subject |
| Parents' evening booking | Newsletter and reception |
| Trip consent forms | Letters home |
| Lab safety procedures | Bench signage |
| Campus wayfinding | Building entrances |
Worksheets
A code on a worksheet is scanned at 20–30 cm, so 2 cm is enough. Print the URL as text too — half the copies will be photocopied, and photocopying degrades a small code quickly. If worksheets are routinely photocopied, use a larger code with error correction Q.
Safeguarding
Codes on public-facing school noticeboards can be covered with stickers by anyone. Check external signage regularly, and prefer codes pointing at your own domain so a substituted sticker is more obvious when the destination is read aloud.
Library shelving
Shelf-end codes pointing at a subject guide, reading list or catalogue search work well and are read at 30–50 cm, so 3–5 cm of code. Keep the URL stable — reading lists change, shelf labels do not.
