Men will
generally always inflate what could be considered a positive aspect of themselves to others: be it height, penis size, muscularity, intelligence, etc.
In fact, I often see men rounding up their heights to 170cm and 180cm when they're shorter than that, but those numbers are around the average of the countries they live in. I'm talking about 3-4cm of rounding up.
I personally round 173.7 cm to 174 cm but adding another 5 cm to be almost 179 cm will be laughable.
Actually, this seems easier to pull off in the US (due to the Imperial system, maybe). I've read about users here who were 5'6 claiming to be 5'8~'5'9 in their online dating profiles, and not being called out on it. That's being 1,67m and claiming to be 1,73~1,75m in metric. I guess it's a combination of shorter people (than you) having a harder time estimating the height of taller people, the fact that most men inflate their height so most people don't have a real grasp of what the the real heights look like, and that inflating your own height in a country that uses the Imperial system skews people's perceptions even further from the truth. Some people might just not care as much after meeting in person, too.
