Checkbox labels should be short and direct. The text should clearly communicate what happens if the checkbox is selected. Avoid full sentences unless absolutely necessary.

Use positive and active language for checkbox labels. Avoid negative language, which would mean that the user has to check the box in order for something not to happen. This can be confusing. Opt-in scenarios should also be unchecked by default.¹

Use sentence case--capitalize the first word. Do not include periods unless each checkbox label is a complete sentence.

You can optionally include a label as a header to describe a group of checkboxes. Labels should be used if the selection is required, and they should indicate the requirement with an asterisk.

For a group of checkboxes, use parallel construction when writing the labels. For example, each item should be a noun or a short phrase that starts with a verb. A consistent structure makes it easier for users to scan and read the list. Minimize the number of repeated words and try not to start every item with the same word.

You may use first person (I, me, my) to clarify how the action relates to the user. For example, "I have read to and agree to the terms and conditions."
