Swipe apps have ratcheted up expectations to unrealistic levels. The only hope for sub-180s is to meet people in real life via acquaintances with mutual attraction. The game has changed and the old rules don't apply any more.
I'm guessing 180 is 180cm, as 183cm is 6ft which fit's in to the whole "don't swipe if under 6ft" meme. Which, in case you're unfamiliar with it, is a popularised (no idea if it's actualy popular) line on dating app profiles where you swipe to indicate interest in talking. Which somewhat demystifies the rest.
