Golden ratio
I keep bumping into overcomplicated instructions to construct a layout based on golden ratio (such as this one). Although most of it looks cool and somewhat esoteric, it’s too much to do on a daily basis.
I use two simple formulas:

For example say your website is 960px wide:
960px × 0.618 ~= 593pxfor content column960px × 0.382 ~= 367pxfor side column
