Images
We've already mentioned the different sizes of lettering which should be used for various distances, but there is another reason for having a variety of sizes: it makes for more interest. Apply the same reasoning to the pictures you use too, whether they are photographs, diagrams, or drawings.
Photographs in particular need variety of size: some pictures are more important than others, so make them the big ones and the rest smaller.
And why not go for at least one really big picture? Most digital imaging studios and exhibition companys can now produce very large images relitively cheaply.
The right images can reflect the culture of a business or can help to change customers perceptions. They can suggest solidity and reliability or youth and energy; choose your images well and you will maximise the impact of your stand.
