## T-Shirt Sizing

"T-shirt sizing" or "T-shirt size estimation"
is a method of project estimation
characterized by the use of T-shirt sizes
representing project scale buckets.

> [!example] [T-Shirt Sizing in Agile --- Project Management Pathways](https://www.projectmanagementpathways.com/project-management-articles/tshirt-sizing-in-agile-projects)
> * **XS (1-2 days):** Simple UI changes or minor bug fixes
>
> Example: "Update button color on checkout page"
>
> * **S (2-3 days):** Feature enhancements with minimal complexity
>
> Example: "Add product sorting by price"
>
> * **M (5-7 days):** Features requiring moderate integration
>
> Example: "Implement basic search filters"
>
> * **L (8-10 days):** Complex features affecting multiple components
>
> Example: "Create shopping cart functionality"
>
> * **XL (2+ weeks):** Major features requiring breaking down
>
> Example: "Implement payment gateway integration"

The buckets chosen should be wide enough
that scale can be confidently estimated
after minimal investigation.

This method, as an ordinal scale
is criticized as error prone and unhelpful
in [[how-to-measure-anything-in-project-management]].
