How T-Shirt Sizing Works

T-Shirt Sizing is a simple and intuitive estimation technique for agile teams. Here's how to use it:

  1. Create or Join a Room: Start by creating a new room with a descriptive name or join an existing one using the provided 8-character code. The room creator is automatically assigned as "Admin."
  2. Set the Story Title: The Admin enters the title of the user story or task being estimated.
  3. Select Your Size: Each participant privately selects a t-shirt size representing their estimate:
    • XS (X-Small): Trivial task, minimal effort
    • S (Small): Simple task, low complexity
    • M (Medium): Standard task, moderate effort
    • L (Large): Complex task, significant effort
    • XL (X-Large): Very complex, major effort
    • XXL (XX-Large): Epic-sized, should be broken down
  4. Reveal Votes: Once everyone has voted, the Admin reveals the estimates, showing individual votes and the most common size.
  5. Discuss and Reset: Discuss any discrepancies, then reset votes for the next story.

T-Shirt sizing is perfect for high-level estimation and early planning phases when detailed estimates aren't needed.
