It's stickied in the Reference Library:

Style Codes and Dimensions of the Timeless Classics

I compiled this list with info collected from my own files, chanel.com and the Chanel forum. Many thanks to Cyndee and nscwong.

Please let me know if you have any changes or additions.

Thank you.

Bump

no problem. shall we give you colour code of all the classic bags that we have?

Well, many color codes are being used for one season only. Which is why people always get confused about them So, only if we're sure the color code is consistent, like the black.

Hi, DH just bought a reissue 226 back from Barcelona.
Was told by the SA that it's called the Medium size instead. Anyway the length is 10" but the width is 3.5" instead of 2.5". Is this bag a seasonal item hence the difference or have they changed the measurement? Thanks in advance!

Congratulations on your reissue! Yes, the 225 is called small, 226 = medium and 227 = Jumbo size.

The dimensions stated in the reference thread are approximate dimensions, collected from info of tPFers. The width of the former 226 reissue was smaller, which would explain the difference. I will change it into 3.5" in the reference thread.

Jumbo Kelly L x H x W - 12" x 9" x 5"

Thanks, Carole.

Thanks, Nat. Glad to hear that it's not a seasonal item. DH is quite clueless regarding chanel bags...

He did a good job

Never mind.

No changes or additions? I guess I did a good job, then. LOL!
