Correction: shrinking the feature size by 50% lets you add 300% more transistors!

Transistors half as big implies twice as many transistors in each row, and twice as many rows, for a quadrupling of the number of transistors.

That's why you see the oddball numbers for feature size: since wafers are two-dimensional, to double the number of transistors you only need to divide the feature size by the square root of two.
