GOV.UK Design System: Character count

Documents character count for limited textarea content with max characters or max words, thresholded count display, assistive-technology messages, static no-JavaScript fallback text, error handling when over the limit, and research-backed advice to test without the component before adding it.

Pattern Decisions This Source Supports

Pattern Supported decision Required contract Claim note
Character count Choose character count when the limit is real, useful to users, and enforceable in the same unit displayed by the interface. The field accepts typing and paste normally; the counter observes length rather than blocking editing prematurely. GOV.UK character count guidance supports max characters, max words, thresholds, assistive messages, fallback text, and over-limit errors.
