Paper and envelope sizes confuse me! While I know that US letter paper is 8.5 x 11”, and US Legal paper is 8.5 x 14”, that is only the start of the sizes that can appear in a print dialog box. Of course, just where to select a paper size in a Macintosh application is also undergoing changes. In TextEdit, paper size is selected in File -> Page Setup. The size choice will look similar to this if you have not selected a specific printer: In Apple’s Pages, while you will use the same command in the File menu, the printer you are using will cause changes in the Paper Size pop-up menu.

Even more confusing is Address Book. There is no Page Setup item in the File menu. Instead, you will need to select the type of item you want to print in the Print Dialog box. Then, your paper size choices will appear as a drop down list. This box shows what is available when my Epson Stylus Photo RX600 is selected.

The list looks entirely different if I choose my Brother MFC-7820N:

So, the paper selections available are controlled by the printer driver, not the application you are using.

While some programs list the size of the item in the dialog box…

Applications that do not have a Page Setup menu item (such as Address Book) may leave you clueless about the item’s size.

I feel your pain! It would be really nice to have a place that lists the names and sizes of all these papers and envelopes! I spent quite a few hours last week making an exhaustive list to fill that need, and here it is! I know that you can find even more. I did. But, I had to stop somewhere!
