The propeller on the Linke-Hofmann R.II (1919) holds the record at 6.9 m (22 ft 6 in).
What are some of the largest propellers post-WWII? Top 5 or so.

7$\begingroup$ The largest propellers today are mounted on top of a large mast and connected to a generator. Here the record was held for many years by the Growian experimental windmill, which ran first in 1983 and had a rotor of 100m diameter. Modern offshore windfarms have now reached dimensions of up to 170m rotor diameter. $\endgroup$– Peter KämpfJan 27, 2017 at 17:58

$\begingroup$ So, are we not counting propellers on helicopters? $\endgroup$– ShufflepantsJan 27, 2017 at 22:52

$\begingroup$ Depends on what measure you use. None of them ceased production before 1946. $\endgroup$– AoeuidJan 27, 2017 at 18:17

3$\begingroup$ It would be wonderful to see metric equivalents of these fine numbers $\endgroup$– NayukiJan 27, 2017 at 18:28

1$\begingroup$ @Aoeuid post-WWII means "after WWII." That is, they started production 1945 or later. $\endgroup$– reirabJan 27, 2017 at 20:00
