What principles should be applied to the physical features of the text?
The speed by which letters and words can be recognized (legibility) can be enhanced by applying the following principles. Sections: Divide the text appropriately into short sections. Use headings or other highlighting/separation devices. Major headings, including captions and subtitles, should capture the main points. Within the text, bullet text is helpful. When creating headings, it is acceptable to use uppercase letters and bold print. Type: Base the type size and font on the needs of the target audience. Use at least a 12 point type size whenever possible. For elderly or visually impaired users, use at least 14 points. For headings, use ranges from 18-36 points. Use a serif font for the text. It allows more variation among letters than sans serif. This makes the letters easier to recognize. Use both upper and lower case letters in the body of the text. It is more difficult to read all capital letters. Use black type on a white background for best contrast. It is the easiest to read
