Tshirt sizing has become a popular method for estimating in agile projects. So, in this video, I answer the question, what is Tshirt Sizing?

Tshirt sizing is a simple and popular way to estimate the relative scales of different pieces of work. The method is usually used in agile projects and applied to User Stories.
We have a video on that:    • What are Agile Epics, User Stories, a...  

Different users have different sizes, but a common approach might use sizes:
• Extra Small (XS)
• Small (S)
• Medium (M)
• Large (L)
• Extra Large (XL)
• Extra Extra Large (XXL)

Fibonacci numbers for sizing:
• XS – 1
• S – 2
• M – 3
• L – 5
• XL – 8
• XXL – 13

Number of iterations, or sprints, they will need, to develop the functionality:
• XS less than 1
• S = 1
• M = 24
• L = 48
• L = 8+

Process
1. Agree on your sizes and their definitions, and then make your Tshirt size cards
2. Product Owner explains the user story that needs an estimate. The development team asks questions to gain the understanding they need.
3. Each developer gives the user story a tshirt size.
4. All developers raise their cards simultaneously.
5. The development team discusses the differences and the product owner offers further clarification, if necessary.
6. The team repeats Steps 35 until they agree on the size.
