Computer Type is NOT Print Type

Accordingly, many principles related to the choice of print type do not apply when the medium is a computer monitor. A starting point is to acknowledge the limitations of the new medium. These include:

Limited availability of fonts Poor font resolution Lower character/background     contrasts Reading distance is fixed, and     may be uncomfortable Reduced hand/body motion and     a rigid posture increase fatigue Difficult to focus: emitted light, flicker,     glare, on a curved surface

Low resolutions and small displays     increase page turning Layout is less flexible: some bad     margins, inelegant line widths and     clumsy justifications may have     to be accepted Unfamiliar environments and     feelings of impermanence     create additional stress
