A box the size of a fingernail

Whoever makes a new breakfast cereal will spend more hours looking at its box than every shopper in Cairo put together. That is worth remembering when the arguments about the shade of the lettering start. If something about it bothers the people who made it, it may never bother anyone else.

What matters more is how the box behaves once it leaves the design desk.

It has to read at the size of a fingernail, because many people will first meet it as a small square on a phone screen, in a delivery listing or a supermarket's message, long before they see it on a shelf. A detail that only works when the box is in your hands is a detail most people will never notice.

It also has to say, at a glance, which aisle it belongs in. A shopper scanning a shelf of cereal is matching shapes and colours against what cereal is supposed to look like. A box that speaks that language gets considered. A box that is only beautiful gets skipped, because nobody recognised what it was.

Inside that language there is room to lean. A box can say it is a cereal and also that it is the slightly more serious one, or the one for people who rarely buy cereal at all. That small signal is the design's real work.

And here is the part that saves a lot of anguish. Nobody buys a cereal because of its box. The box can only stop them. So the brave, strange idea that would look wonderful in a portfolio is usually a risk with no prize attached.

The box is not there to win anyone over. It is there to lose nobody.
