How to design a hoarding that works

A hoarding is read in about three seconds, by somebody who is driving, from a distance of thirty metres or more, once. Every design decision follows from that. One message, one brand, six or seven words, high contrast, and type big enough to read at speed. Nothing on it can ask the reader to do something a moving vehicle will not allow. Most bad hoardings in Bengaluru are not ugly. They are simply full.

Start with the road, not the artwork

The same panel size works differently on three roads. Beside a signal on Bannerghatta Road the vehicle is stationary for thirty or forty seconds. A phone number, an offer with a condition, even a QR code all become possible. On the Outer Ring Road crawl towards Marathahalli the reader has a minute but keeps glancing away, so a name and a category line registers and a paragraph does not. On the approach to a flyover the vehicle is accelerating, the viewing angle closes fast, and you have four words.

So ask the media owner one question before briefing a designer. Where is the vehicle when it reads this, and is it moving? The pricing guide for Bengaluru hoardings covers what that does to the rate. Here it decides the artwork.

Ask for the exact panel dimensions and the site photograph too, shot from the driver's position rather than from below the structure. Decks are full of photographs taken from the base of the pole. No buyer ever stands there. A panel read at an angle loses a third of its width to foreshortening. A design centred in the file then sits off to one side of the eye.

Check what stands beside it as well. Three panels in a row on Tumkur Road are read as one wall, and the loudest colour in that wall wins. If both neighbours are white, go dark.

The elements, in the order they are seen

A reader takes in a hoarding in a fixed order: the picture, the biggest words, the brand, then everything else if there is time. There usually is not.

The brand name. Large enough to be recalled even if nothing else is. If somebody remembers the hoarding tomorrow but cannot name the advertiser, the money went to the media owner and nowhere else.

One message. Not the range, not the three reasons. One. A modular kitchen company on Kanakapura Road can say the offer, or the new showroom, or the brand. Not all three.

One picture, reading at thirty metres. A wide product shot with six items in it becomes a grey rectangle. One object, large, against a plain field.

A direction, if you have one. "Next signal, left" or "200 metres ahead" is the strongest call to action outdoor has. It is the only one the reader can act on without stopping. A full postal address is not.

Type, colour and the squint test

Set the headline in something heavy and plain. Condensed type looks efficient in the file and closes up into a smear at distance. Thin weights disappear against a bright sky.

Contrast does more than size. Black on yellow and white on a deep solid colour survive glare, dust and an unlit night. Red text on a blue field, or a pale grey line on white, dies in the first week of Bengaluru dust. If the site is unlit, remember the panel is invisible from seven in the evening, which is exactly when the road is fullest.

Then the test that catches almost everything. Print the artwork on a single A4 sheet, put it on the far wall, and read it from four metres in one glance. If you have to hunt for the brand, or you read it twice, the panel fails. We run this check on every outdoor file that leaves our office in Nagarbhavi, and it is the reason fewer proofs come back from the printer.

What the file has to allow for

Flex is stretched over a frame and pulled tight at the eyelets, so the outer edge wraps around the structure and disappears. Keep every word and the logo well inside a margin of about six inches on each side at full size.

Large panels print at a coarse resolution because nobody views them from close up. Build at one tenth scale at 300 dpi, keep type live and vector, and convert fonts to outlines before sending. Get the printer's own template first. The specifications guide has the rest of the deliverables, medium by medium.

One more thing that ruins finished panels: the colour you approved on a screen is not what solvent ink puts on flex. A brand red will shift. Print a small swatch on the same material from the same machine before the full run if the colour is the brand.

A worked example

A dental clinic in Rajajinagar buys two panels for three months. One sits beside the signal on Dr Rajkumar Road, the other on a free-flowing stretch of the Outer Ring Road near Nagarbhavi.

The signal panel carries the clinic name, the word implants, a WhatsApp number and a QR code a foot across. The rider beside it is stationary with a phone already in hand. The Outer Ring Road panel carries the clinic name, the word implants, and "Rajajinagar, next to the metro". Same campaign, same colours, two different artworks. The two readers are in different physical situations.

The clinic then puts a distinct number on each panel so it can tell which road produced the calls. That part is covered in how to track a hoarding campaign.

What a panel cannot be made to do

No amount of design fixes the wrong brief. A hoarding cannot explain anything. If your product needs a sentence of explanation before a buyer understands what it is, outdoor is the wrong place to introduce it. The panel will work only as a reminder for people who already know you.

It also cannot carry a conditional offer. "Flat 20% off on selected models above ₹40,000, till 30 September" is four facts, and a driver keeps one. Put the discount on the panel or the deadline on the panel, and hold the conditions for the page the QR opens.

And it cannot be made accountable at the level of a person. You will know what happened to enquiries from that catchment while the panel was up. You will never know who looked.

What to do next

Take your last hoarding artwork and count the words. If it is over seven, decide which single message survives and delete the rest, then set that one line twice the size. Ask for the site photograph from the driver's seat before the next booking. If you want a second pair of eyes on the panel and the road together, book the free audit and bring the media owner's deck with you.
