Digital Signage Content: Getting It Read

Start with dwell time

The single most useful number is how long your audience is in front of the screen. A window display facing a pavement gets three to five seconds. A queue at a counter gets a minute or two. A waiting room gets ten minutes or more.

Content is designed to that number. Three seconds allows one message, big. A minute allows a rotation of four or five. Ten minutes allows genuinely longer-form content, but even then, nobody watches continuously — they glance up, so each frame still has to make sense on its own.

One message per frame

Every slide should have a single job: this product, this price, this offer, this instruction. When a slide carries three competing messages, viewers read none of them, because deciding what to look at takes longer than the glance they were going to give it.

A useful discipline is to write the message as a short sentence first, then design around it. If it takes two sentences, it is two slides.

Legibility at the real viewing distance

Text that reads comfortably on a laptop is frequently unreadable at four metres on the same screen. Design at the distance the audience will stand, then check it in place. As a rule, headline text needs to occupy a substantial part of the screen height, body text should be minimal, and thin light typefaces fall apart at distance.

Contrast does the rest. Light text on a dark ground or dark on light, never text laid over a busy photograph, and no reliance on colour alone to carry meaning.

Rotation, timing and motion

Keep loops short. A loop of four or five slides at around eight to ten seconds each means anyone passing sees at least one, and the whole loop completes while a queuing customer is still there. Long loops mean the important slide is usually the one nobody saw.

Use motion sparingly. Gentle transitions and a single moving element attract attention; constant animation everywhere is tiring, and it makes reading harder. In shopfronts, remember that moving imagery is also the aspect councils scrutinise most closely, so it may be constrained by the terms of any consent.

Build templates, not one-off designs

The realistic failure point is maintenance, and templates are the fix. Create a small set — offer, product, price list, notice, welcome — with fixed positions for logo, headline, image and price, so updating means replacing text and a photograph rather than designing from scratch.

Templates also keep multi-site estates coherent, because a manager updating a local offer cannot accidentally invent a new brand look.

Give someone the job

Content needs an owner, a schedule and a review date. A monthly slot in someone's calendar to refresh slides and delete anything expired is enough for most businesses, and it is the difference between a display that looks alive and one that quietly advertises a Christmas menu in June.

Also decide what shows when there is nothing to say. A default slide — your brand, opening hours, a standing offer — is far better than a blank screen or a stalled slide, and it stops the display looking broken during quiet periods.

Things worth avoiding

• Slides carrying paragraphs of text, which nobody reads standing up

• Content with visible dates that will age badly if it is not refreshed

• Sound in a retail space, unless the environment genuinely supports it

• Screens showing a desktop, a screensaver or an error message, which undo a lot of goodwill

• Portrait content stretched into a landscape screen, or vice versa

• QR codes placed too high or too small to scan from where people stand

Measuring whether it works

You do not need analytics software to learn something. Put a code or an offer that only exists on the screen and count redemptions. Ask counter staff whether customers mention it. Rotate two versions of a message and compare.

That habit turns a display from decoration into a channel — and it also tells you honestly whether the position and content are earning the investment.
