What Is the Right Size for a User Story?

There is no one-size-fits-all user story.

A question that comes up again and again from teams is “What is the right size for a User Story?” -- a day? a week? three weeks? 1 point? 5 points? 10 points? 37? 100? 5 words? 20 words?

Short answer: There isn’t a universal right size for a User Story; it depends on your team, their skills, and their level of domain knowledge.
