So we are setting up a printable coupon page (using a print media query in css) which gives you a good bit of flexibility but it got me wondering; how often are people printing pages outside of 8.5 x 11? Everything on the modern web revolves around responsive layouts, but if printed pages are always at this size are we safe setting up these stylesheets to be static? I know in Europe they use something close to letter size but not quite, but we are still talking about a very similar aspect ratio and width. Anyways would love to hear thoughts on this.
how often are people printing pages outside of 8.5 x 11?
I have never printed at 8.5 x 11. I assume this is a U.S. paper size and is in inches.
I print at A4, it is the standard printer size in the UK. It is 210mm x 297mm.
Don't try to assume what sizes people are printing at, instead make your print styles flexible enough to cater for everyone (including me).
Anyway, people can always change the print size (in percentage) to make your page fit to whatever size paper they have anyway. Try not to limit the amount of people your print stylesheet will be useful for.
There are basic rules to bear in mind when styling for print. Some advice here:
