Hi, Stew!
Another hornets' nest waiting to be shaken!
As I understood it, in imperial paper sizes, it was always height first by width second.
However, many people now prefer to reverse the order.
I know Ed Poole at LAMP always goes width first by height second.
I guess it depends where you learned it first and who you listen to now!
I was working on the basis that 'bus stop' was the 'modern' term for 60" x 40".
Apparently, according to Paul's posting, that's not the case - sorry, I was under a misapprehension - stuck as I am in the olden days! I shall continue to avoid the term 'bus stop' altogether!
If in doubt, you can't go wrong if you spell it out in full - ie 60" high x 40" wide, etc, etc.
Best wishes,
Terry -
