T-Shirt estimating poker cards

I‘ve been a big fan of abstract estimating cards for a long time, and I’ve especially enjoyed using T-shirt sizes. T-shirt sizes are great because the enable communication with Product Owners; they immediately understand that a Large body of work is going be to bigger than a Medium body of work yet smaller than an XLarge body of work. And, most people are also culturally aware of T-shirt sizes so it feels very natural to use them.

After some discussion with my brother (who did all the art work), I’ve finally produced a packet of T-Shirt Estimating Poker cards that I’m really happy with. There are only 6 cards per suite including: Extra Small (XS), Small (S), Medium (M), Large (L), Extra Large (XL) and finally a question mark (?). Because there are just six cards per suite, that allows a total of nine suites per pack of fifty-four cards.

Here’s what a complete suite looks likes …

I have a large box filled with T-Shirt Estimating Poker cards in packs, and for a limited time I thought I’d offer them for free. So, if you’d like a pack of T-Shirt Estimating Poker cards please send me an email at kane@scrumology.com with an office address that you’d like me to send them to. As soon as I have time to put them in the mail, I’ll let you know. I had a large box filled with estimating poker packs … but now they’re all gone. I’ll re-open the offer once I get some more cards made up.

    Kane, I’m making the move from numbers to t-shirt sizes to simplify the sizing conversations.  Please let me know if and when you ever have more cards made.  Thanks!

    Hi Kane,

    Can you please tell me where you got your cards printed? I was hoping to print some custom cards myself.

    Thanks.
