The RR Avenue standing male figures are mostly between 3.4 and 3.6". All are wearing shoes and most have a cap or hat. Bare headed or with a cap are among the shorter and the ones with a hat are the taller ones. Basically the standing males are right at 3.5" or 5' 11" in 1:20 scale. The pregnant woman with three kids holding onto her skirt is ~3.1" or ~5' 3" in 1:20 scale.
Thanks guys. According to my 1:22.5 scale card the average male height just under 6 ft tall is about 3 1/4. I'm surprised there is not more of a difference given what appears to me as a big difference in the size of 1:20.3 vs 1:22.5 equipment. I know the math supports the minimum change in height but it just seems like they should be bigger.
6' in 1:22.5 scale is 3.20"
6' in 1:20.32 scale is 3.54"
Difference is .34" or about 11/32", closer to 3/8" than 1/4".
Remember that on a 3D model you are looking at the volume of the object which makes things appear significantly larger than the linear dimension differences would imply. The fact is, 1:22.5 figures, when used in the foreground, look pretty wimpy alongside 1:20 figures or other 1:20 scale items such as doors.
Using those same 1:22.5 scale figures a little further away and not next to 1:20 scale items can actually provide a forced perspective, helping enlarge the scene.
