The Poster That Fails Its Brief
A student is designing an A3 poster for a school water-saving campaign. The brief states: the headline must be readable from 3 metres, the poster must work in black and white for photocopying, and it must include one clear call to action. The student produces a design with a photographic image of a tap, a headline in a thin light typeface at 14 pt, six lines of body text, a decorative border of small water droplets, and the slogan placed in the bottom corner. The teacher observes that the poster looks attractive on screen but fails when printed and pinned at the end of a corridor.
1. Identify the specific brief failures and explain the design principles each one violates.

Failures: (1) The headline at 14 pt in a thin light typeface cannot be read at 3 m; legibility at distance requires large x-height and heavier weight. This violates hierarchy and scale. (2) The design relies on the photograph's tonal range; photocopied in black and white, the tap may merge into the background, losing figure-ground contrast. (3) Six lines of body text compete with the headline rather than supporting it, so there is no clear focal point. (4) The call to action is in the bottom corner, small and peripheral, so it is not the second thing the eye finds. (5) The droplet border adds visual noise without carrying meaning, weakening the message.
The underlying problem is that the student designed for a screen at close range, not for the viewing distance and reproduction conditions in the brief. A poster is read in a glance, so one dominant message, one supporting image and one clear action should form a simple visual hierarchy.
2. Redesign the layout in principle, describing the changes and how you would test the result against the brief.

Redesign: make the headline the dominant element, set in a bold sans-serif at roughly 60–80 pt, occupying the upper third. Reduce body text to one short line. Place the call to action directly under the headline in a contrasting weight or inside a solid shape, so it reads second. Use a single high-contrast graphic of a tap and a droplet rather than a photograph, with strong black-and-white separation and no grey mid-tones that photocopy badly. Remove the decorative border.
Testing: print a black-and-white proof and pin it at the end of a corridor; check that the headline is readable at 3 m and that the call to action is identifiable at 1.5 m. Photocopy the proof and check that the tap shape and text remain distinct. Ask two people to state the message and the action after a three-second glance; if either is unclear, adjust scale or contrast and retest.
