The following advice from David Marshall is based on the experience and science behind signage and layout, fonts, colours, visual acuity, value for money, and best practice.
We can learn a lot from how professional signage planners communicate information. They use a process I call, Identify, Detail, More Detail.
As you get nearer, so the signs give more detailed information, such as the services on offer. The sign, near the door, offers details of opening times, while a further board inside identifies the manager with other staff names and photos.

In the church we often do the opposite of the Identify, Detail, More Detail approach, cramming our boundary notice boards with as many words as we can fit in. Our content is sometimes unfriendly. How many church notice boards have the word welcome on them, despite this being part of our mission?
The Identify, Detail, More Detail approach is great news for the Church as it offers us a simple template for successfully shifting preconceptions of the Church as aloof and wordy. We can, at low cost, say welcome and make people feel they belong from kerb to pew.
