Artwork dimensions - vertical horizontal or horizontal vertical?

[dwig]

I use 2 "standards" and we use a mix some things at work.

When specifying dimensions with a particular orientation then I use W x H.
When specifying dimensions with no particular orientation (e.g. size of a sheet of paper) I use Smaller x Larger (e.g. A3+ paper is always 13x19 regardless of the orientation the image printed).

At work (a photographer's art gallery), we use W x H when spec'ing the size of piece, but my print files always list the size as part of their filenames using Smaller x Larger. This makes finding the proper files in a large folder containing many files for varying print sizes much much easier.

We have a little debate going here regarding correct display of dimensions. I was taught and have witnessed in every other company I have worked for that when listing artwork dimensions i.e. 55mm x 65mm, the first number should refer to the horizontal dimension and the latter should refer to the vertical.

I have some money on this so cast your votes - do it for the boobs!

Some European countries do the opposite, but here in the states it is always width first, then height... EXCEPT when we're talking about outdoor signage. Many of those companies use height first, but even they are starting to come around.
