If you know anything about the different types of paper stock you can tell at a glance, it is not difficult. On Wednesday before this new picture of the paper carton came to light I recognized it was 8 1/2 x by 11 and said so.
I am familiar with both the American and European sizes.

That’s great, but how would you explain that to a courtroom? Anything concrete or measurable?
