# QR codes for universities

> Universities need QR codes on lecture slides, campus signage, club stalls and lab equipment. The lecture-slide code is the special case: back rows sit 15–20 m away, so students photograph the slide and scan the screenshot later: design the code to survive that, not a live scan.

## The lecture-slide code is a special case

A lecture theatre puts the back row **15–20 m** from the screen. The
[10:1 rule](/docs/print/the-10-to-1-distance-rule) would demand a code **1.5–2 m** wide,
which no slide provides. What actually happens is different: students photograph the slide
and scan the [screenshot](/docs/scanning/how-to-scan-a-qr-code-from-a-screenshot) later.
Design for that:

- **Short URL**, so the code stays coarse. A version 3–4 code survives a blurry photo of a
  projection far better than a dense one.
- Pure black on white. Projectors compress contrast; coloured codes lose more.
- **≥ 15% of slide height**, in a corner clear of the presenter's shadow.
- Print the URL as plain text underneath for anyone typing it later.

## Orientation and wayfinding

New students navigate an unfamiliar campus for weeks. A code on building signage linking to
the campus map with *that building* preselected beats a generic map link. Entrance and
corridor signage is read from 1–2 m, so use **10–20 cm** of code.

## Clubs, events, signups

The freshers' fair is the densest QR environment on campus: dozens of societies, each
wanting a signup list. Generate one code per society
[in bulk](/docs/how-to/how-to-make-qr-codes-in-bulk) from a spreadsheet, and add a
[calendar code](/calendar-qr-code) for taster sessions so the event lands in a diary rather
than a forgotten flyer pile.

## Lab equipment and SOPs

A laminated tag on each instrument (linking the standard operating procedure, the booking
sheet, and a fault report with the asset ID prefilled) is the
[asset-tagging pattern](/docs/ecommerce/qr-code-asset-tagging) applied to a lab. It retires
the "where is the SOP binder" question permanently.

## Who owns the template

A university prints thousands of posters a term from hundreds of independent groups.
Without a standard you get low-contrast brand-colour codes and links to expired student
hosting. Publish a one-page internal rule set: minimum sizes,
[colours that scan](/docs/design/qr-code-colors-that-scan), official domains only, and
share a generator link with the defaults already in the query string, so the template
enforces itself.

## FAQ

### Can students scan a QR code from the back of a lecture theatre?

Rarely in real time, at 15 m the 10:1 rule requires a code around 1.5 m wide. Most
students photograph the slide instead and scan the photo afterwards, which works well
provided the code is large, high-contrast and encodes a short URL.

### How big should a QR code be on a lecture slide?

At least 15% of the slide's height, with the quiet zone kept clear. Bigger is better
because the common path is scanning a photograph of the projection, and a small dense code
does not survive that.

### What should university QR codes link to?

Stable institutional URLs: the module page, the society signup, the campus map with a
building preselected, the instrument's SOP. Avoid personal or student-society hosting that
disappears at the end of the academic year.
