If you get your aspect ratio wrong then everything else is wrong. You have to nail your ratios properly or your work may not play back as well as intended. Furthermore, the correct aspect ratio lends to greater workability as far as processing is concerned.
Same thing just from a different perspective and fresh words.. the first link gives me headaches.. ffs... need to read it at least 4 or 5 times...
It's very tricky this aspect ratio stuff and most of the information I knew about it, is just plain wrong.. so read up... this is very important if you want to make serious vids.

16:9 Guide Graphic
