UX Design
Microcopy
Microcopy is the small, functional text scattered through an interface — button labels, error messages, placeholders, tooltips, and confirmation lines. It is the writing that guides a single action rather than explaining a whole page.
Why it matters
These tiny phrases shape how trustworthy and clear a product feels, often more than the headline copy. A well-worded error or button can be the difference between someone finishing a task and giving up.
In depth
Because each piece is short, microcopy is easy to overlook until it is wrong — a vague button or a blaming error message creates friction in a moment when the user is already unsure. Good microcopy is specific, calm, and written from the reader's point of view. Write it early rather than treating it as placeholder text to fix later, since the words often reveal gaps in the design itself.
Real-world example
When Mailchimp tells you "You're all set" after a send, or a form says "We'll never share your email," that reassurance is microcopy doing quiet, useful work.
