Was wondering how much these irons are off from generally accepted industry standard lengths?

All measurements are approx. I don't have the proper clubmaker measuring device.

3 iron: 38.25"
4 iron: 37.75"
5 iron: 37.25"
6 iron: 36.75"
7 iron: 36"
8 iron: 35.75"
9 iron: 34.75"
PW: iron: 34.75"

And like I said, there could easily be a variance of 1/8" or so. Just trying to get a general idea. Thanks.
