Guiding principle: Give the user control.
When to use this component
A text area (or
text box) is a multi-line field where the user can type in information.
Use a text area if you want the user to enter more than a single line of information.
Do not use a text area if:
- you want users to enter answers that are only one line (instead, consider a text input)
- it will be easier for the user to choose from a set list of options
- users can find open-ended questions difficult to answer, so only use them when it doesn’t make sense to give them answers to choose from with a dropdown list, radio buttons or checkboxes
Examples of where to use text areas include:
- comments and user feedback
tell us about yourself sections
- requests for more detail
In general, give the user control of what they’re entering.
- always include an associated label with a matching ID
- include hint text only if needed
- left-align text fields (as well as their labels and hint text)
- allow the user to:
- copy and paste text
- input any characters (although this doesn’t mean they can submit any type of character, and remember you can reformat responses on the backend)
- make their answer as long as they want (although they may get an error)
- make the input field the appropriate height for the type of answer you want
- this serves as a visual indicator for about how long the user’s response should be (for example, about 3 lines)
- have the text area take up the full width of the surrounding container
- preserve line breaks using
- limit the number or type of characters the user can input
- instead, give clear instructions and/or an error message if needed – for example,
Tell us about yourself (200 word maximum length)
- put placeholder or hint text within the text area
- remove the resizing handle in the corner of the text area that allows users to drag the corner of the field to make it longer or shorter
- put a label or hint text in the text area itself
- using “placeholder text” like this is not a good practice from a usability or accessibility perspective because it disappears when users start typing
