Radio

Radio buttons allow users to make a single selection among a group of options. In a form, always place radios underneath one another to aid in a user's ability to scan the form.

Size

Reserve the small appearance for data-rich, dense interfaces.

Guidelines

• List options in a logical order (alphabetically, numerically, time-based, etc.)
• Most likely to least likely to be selected
• Include at least two or more choices
• Include mutually exclusive options—this means that each option must be independent from every other option in the list
• By default, no radio elements should be selected
