Choose legible fonts. Sans serif fonts (eg Helvetica, Arial, Verdana) are often considered to be easier to read than serif fonts on computer screens and mobiles, especially in longer stretches of text. However, serif fonts that have been designed for onscreen use (eg Georgia, Merriweather) may be better in low-light conditions and on low-resolution screens. Familiarity of the user with the font style also plays a large role in how legible it is.

Do not use images of text rather than text unless essential. Making images accessible requires more effort, and reading images requires more effort from assistive technologies. If you want to show text, present it as text.

Do not use repeated blank characters (eg spaces, line breaks, paragraph breaks). When a screen reader identifies blank characters, this is often a signal to the reader that the information has ended in that location.
