Ah but don't forget that Legolas was comparing them to a bunch of hairy Dunedain rangers dressed for the worst that the wild could throw at them, and with the noted height of their maternal grandparents they were unlikely to be short by the measure of the elves - however I expect the mannish blood may well have made them more strapping than the average elf... though this now leads me to envisage Arwen as a jolly-hockeysticks Betjemanesque heroine...
