TextArea allows for multi-line input.

also known as Multi-line Input

An text area field labeled About You, with text entered.

Usage guidelines

When to use
  • Allowing users to input long portions of free-form text while ensuring all text entered remains visible.
When not to use
  • For inputs that expect a certain format, like a date or email. Use a TextField instead.

Best practices

  • Use TextArea as an affordance to input longer-form text content — typically anything longer than a brief sentence.
  • Use a label to clearly denote what information the user should input. Use placeholder sparingly as they can erode usability of form fields.
  • Use helperText to provide additional context that will aid the user in most effectively inputting information.
  • Set the height of TextArea using text rows to ensure that the typical amount of text entered will be visible without needing to scroll.
  • Don’t use TextArea when the text input is a single, non-sentence response — even in cases with long content. Use TextField instead.
  • Don’t set the row number to less than 2. Use TextField when expecting only a single line of text.

People use Android's accessibility features, such as TalkBack and dynamic text sizing to personalize how they interact with their devices. Supporting these personalizations ensures that everyone has a great user experience. See Material Design and development documentation about accessibility for Android:

Be sure to provide instructions to help users understand how to complete the form and use individual form controls.


Ensure the labels are precise and concise. Labels should only describe the text field they are associate with, and they must be visible.


When providing a validation message, make sure the instructions are clear and help users complete the field. For example, "This field is required to submit". In addition, use the helper text to provide instructions to help users understand how to complete the text field or to indicate any needed input, allowed formats, timing limitations, or other pertinent information.

These practices give users of assistive technologies more information about the form, helping them to fill it out.

Design tokens




TextArea will expand to fill the width of the parent container by default.

Helper text

Whenever you want to provide more information about a form field, you should use helperText.


TextArea can be disabled to indicate the user is unable to interact with it. Disabled fields do not need to pass contrast requirements, so do not use a disabled TextArea to present information important information to the user.


TextArea can display an error message. Don't use errorMessage to provide feedback on character count errors. See the maximum length variant below for more details.

Maximum length

TextArea supports a max length . The max length sets the maximum number of characters allowed to be entered by the user in TextArea.

The user cannot exceed the maximum number of characters interacting with the component. Whenever possible, avoid setting initial values from the parent component's state that already exceed the max length.

When a max length is used in TextArea, the component displays a character counter as well as a warning or problem Status when the user reaches or the pre-populated controlled value exceeds the maximum length of characters.

The first example shows a TextArea with a max length warning. The second example shows a max length problem Status.
