T-Shirt sizing is a very popular technique to provide relative abstract sizing for backlog items.
T-Shirt Sizes
Just like the name suggests, common T-Shirt sizes include:
- small (S)
- medium (M)
- large (L)
For additional granularity of sizes the below may also be used:
- extra small (XS)
- extra large (XL)
- extra extra large (XXL)
Relative Sizing
An approach that is common in Agile Estimation is to use relative sizing to size items relative to each other. One common technique for T-Shirt Sizing is to use a 2 series where an S is equivalent of one unit of work or effort required to complete the item, and a M is equivalent to 2 x S and so on:
- XS = 0.5 x S
- S = 1
- M = 2 x S
- L = 2 x M
- XL = 2 x L
- XXL = 2 x XL
This series then provides an exponential scale to work with and can be used in conjunction with Affinity Estimation for example.
