A 14-pin DIP on a piece of perfboard will most likely end up bigger than a Pro Mini
its true that a 14pin dip CHIP is bigger than a 32pin qfp CHIP but to imagine a 14pin dip BOARD would be bigger than a promini is ridiculous. specially considering the pin duplication, unnecessary parts, and wasted space from the sparkfun moron designer of promini. bringing out 14 pins to headers would end up much smaller than promini even with the single cap, crystal, and led circuit required. it looks like somebody has never bothered to actually measure either device or even glanced at the mechanicals.
bringing out 14 pins will always take a fraction that of bringing out 28 regardless of chip package all else equal.
