Setting Paper Size is a must to a designer when starting a new document for a new design works, doesn't matter its Illustrator, Photoshop, InDesign, or any graphic editor you might be using. But, as I still remember when my works are mostly using AutoCAD, setting the Paper Size will be at the end or after completed the drawings on the CAD screen, because the CAD drawing usually will labeled the Scale value according to the drawing size which depends on the paper size to be printed.
Anyway the important to have knowledge in basic paper size and the conversion from one size to another size might save us from printed jobs being rejected just because mistakes like wrong size conversion. Imagine you do artworks for books with 100 or more pages, suddenly 'they' asked you to change the book size.. and you thinking to rescale the whole pages at once by percent. With confident after completion, you send the artworks for printing, and guest what.. the printed book size was wrong.. and you start to feel the disasterrr ☺

But in artworks when the designs are already made or completed, it's not that simply to Scale your whole artworks or documnts (from A4 size to A5 size) to 50% scale.. Nope..!! Not like that, be careful, you might be destroying your design works when you send it to printer.. because the new size if you scale it 50% reduced, you actually make it A6, not A5..!! Reduce A4 to A5 is 71%.. indeed..
