We first noticed the difference at maison ondine in Biarritz. We had designed the room signage to be read at walking pace, from four metres away, in a corridor lit for sleep. It worked. Then the owner asked for a guest book for each room, and we realised we had spent two years learning how to be read quickly and almost no time learning how to be read at eleven at night, in bed, by someone with nowhere to be.

two kinds of time

Most briefs describe fast reading. Wayfinding, packaging on a crowded shelf, a homepage that gets eight seconds before the tab closes. Every sign at ondine was drawn for someone with a suitcase in one hand and a phone in the other. The tools for that are familiar: contrast, a clear hierarchy, short lines, one idea per surface. Slow reading asks for nearly the opposite. Longer lines are fine. A quiet hierarchy works better than a loud one. The reader has already decided to stay, so the job is to keep them comfortable rather than to catch their eye.

For the guest book we set the text in a book weight at 11 on 15 point, with margins wide enough to hold the page open with both thumbs. The paper is an uncoated cream stock that does not glare under a bedside lamp. We cut the number of typefaces from three to one and removed every rule and ornament we had drawn. Nobody who reads it will notice any of this, which is roughly the point.

slow is not the same as old

There is a version of this idea that turns into nostalgia: letterpress for its own sake, sepia photographs, a website that loads as if it were 2006. We are not interested in that. A slow object can be entirely digital. The kōen ceramics shop in Kyoto sells bowls that spend nine weeks drying and firing, and its product pages load in under a second. The slowness lives in the reading, in long notes on clay and glaze set at a comfortable measure, beside photographs that are allowed to be quiet.

A reader who has decided to stay does not need to be persuaded. They need to be looked after.

That sentence is pinned above the sink in the Lisbon studio, next to the printer we borrowed in 2014 and never gave back. It is the closest thing we have to a method.

what it changes in the studio

In practice, designing for slowness means more time on the unglamorous parts of a project. We test body text at real size on the real paper, never on a monitor. We read long pages on a phone on the 28 tram, where the light is poor and the ride is rough. We ask clients how long they expect someone to spend with a thing, and we take the answer seriously, because an evening and a glance are different briefs even when the deliverable has the same name.

The same thinking has changed how we build websites. For the kōen shop we set the product notes at 18 pixels on a line of about seventy characters, left the photographs uncropped and removed the pop-up that offered ten per cent off to anyone who lingered for twenty seconds. The average visit got longer and sales did not suffer. We cannot prove the two are connected, but we have stopped designing as if every visitor is about to leave.

It also means accepting that some of our best decisions will go unseen. A guest in Biarritz will never know why the book on the bedside table felt easy to read. We think that is what hospitality looks like when it is done quietly, and it is the only kind we want to practise.
