The screen is a difficult environment for reading, especially for those with low-vision. Use sans serifs typefaces. As a general rule they work better than serifs for the screen. This becomes very important when type is displayed at smaller sizes. Serif fonts are to be used with great care. Many serif fonts do not display well on the screen, especially when used for continuous text in sizes smaller than 19 pixels. Fine serifs, thin strokes and nuances do not render well. The serifs create visual noise around the letter forms, which detracts from legibility. Avoid ornamental and highly stylized typefaces (Arditi 1991).
