The Highway Hoarding With Twelve Products and Four Seconds

Step 1 - distance

• 50 km/h = 13.9 m/s; 60 km/h = 16.7 m/s.
• In 4 s the driver covers 55–67 m. Design for the far end: 60 m.

Step 2 - minimum letter height

• Standard roadside guideline: about 25 mm of cap height per 3 m of viewing distance (1 inch per 10 feet).
• At 60 m: 25 × (60 ÷ 3) = 500 mm cap height for the main message.
• Secondary line at roughly half that: 250–300 mm.
• Practical floor for anything meant to be read at speed: about 150 mm. Below that it works only for a pedestrian standing at the shop.

Step 3 - test the owner's draft

• 20 mm letters are legible at about 2.4 m. The driver is 60 m away - a factor of 25 too small. All 12 item lines and the prices are functionally invisible.
• 150 mm shop name is legible at about 18 m - also short of 60 m.

Step 4 - what fits on 3000 × 1500 mm

• Shop name in Odia and English at 500–600 mm cap height, two lines maximum: about 1300 mm of width, 1200 mm of height combined.
• One product/claim line at 250 mm.
• A small 'since 1974' lock-up at 150 mm.
• That is three elements. A phone number needs ≥ 250 mm to have any chance, and at 60 km/h nobody dials - drop it and use a direction cue instead if space allows.

State the constraint plainly, then solve it inside the constraint.

Why the photographs cannot work as photographs

• Four-colour halftone is not available. A one-ink halftone at 60 m collapses into grey mush: the dot pattern is finer than the eye can resolve at that distance, so the 'photograph' becomes a smudge that weakens the whole board.
• Two of the twelve sweets are white (rasagola, chhena poda is pale). White-on-white with a single dark ink has no edge at all - the hero product would disappear.

Three workable substitutions

1. Posterised silhouette in the single dark ink: one bold contour of the rasagola in its bowl, cut as vinyl. Shape survives at 60 m; tone does not.
2. Reversed panel: a dark rounded square with the silhouette knocked out in white, giving the pale sweet a strong edge without a second ink.
3. Line icon at 250 mm, drawn with a 12–15 mm stroke - solid enough to read, simple enough to cut.

Recommendation One hero sweet only (the rasagola - it is the shop's identity and the owner's own choice), rendered as a 400–500 mm silhouette on a reversed panel, placed right of the name. The other 11 items move to a menu board at the shop entrance and to a leaflet - the correct medium for detailed, priced information.

Cost check: vinyl silhouette + spot ink stays inside the two-colour budget; a digital four-colour print is 2.5× the cost and fades within a year on that stretch, so it is not a real option.

Lead with his own goal, not with design rules.

• The arithmetic, in one line: 'Your 12 items are set at 20 mm. A driver can read 20 mm letters from about 2.4 metres. Your customers pass at 60 metres. So today the board is readable to somebody standing still in front of it - and nobody stands still on that highway.'
• The trade-off: every item added makes every other item smaller. Twelve items at 60 m means nothing is read; three elements means the name, the sweet and the heritage are all read. More items equals fewer customers, not more.
• Keep the price list where it belongs: the full 12-item menu with prices goes on a board at the entrance and a counter leaflet - the customer reads it after stopping, which is exactly when they need it. The hoarding's only job is to make them stop.
• Show, don't tell: print the two drafts at 1:10 (300 × 150 mm) and put them on the wall. Ask him to step back 6 m - the equivalent of 60 m on the real board - and tell you what he can read. He will read the three-element version and nothing on his own.
• Protect his heritage claim: 'since 1974' stays, at 150 mm, as a small lock-up under the name, because it is a recognition cue, not information.
• Close with the decision: 'Approve three elements today and the fabricator can cut vinyl tomorrow. If we keep 12, we spend the same money on a board nobody can read.'
