The world scale that i set was in openxr, 100% looks small for me, comparing what i see outside, taxiways labels, the yoke dimensions, you should try to increase the value like i did and you would see that taxiways looks more real, in the real life i can see that the dimensions of the taxiways are bigger and the runway (in the same airport where i use to fly in real life and in fs2020), and i think my correct perception is 109%, i even stand up and get off the airplane for looking to the tower and cars, and 109 is the minimum value that bring a real dimension in fs2020, when i go below this value i see stuff too tiny
