How should it be made up?

The following specifications give the best results:

  • Create media exactly at display resolution.
  • Enlarge text and image for best readability.
  • Watch out for positioning at full pixels for rectilinear shapes.
  • Use light colours on a dark background to reduce light radiation and achieve optimal contrast.

Text size

We often use the following rule of thumb to determine the minimum size of text:

height in cm × 5 = reading distance in m

See the table for some examples.

Character height readable until
5 cm ca. 25 m
10 cm ca. 50 m
20 cm ca. 100 m
40 cm ca. 200 m
80 cm ca. 400 m
