Why do the steering wheels seem so big on these A-bodies?

The steering wheel size seems to look fine in the Duster pictured above. I felt the stock wheel in my Dart does have a large look and feel to me .

I purchased a Grant 13+inch wheel for it.Should have it today.I havent measured the stock wheel but its probably like 14 or 15".

I think the Grant wheel will have a beter look and feel in my Dart.Pics comming when I can.I wanted to be careful with size choice because I didnt want wheel that is too tiny either.I do have power steering so Im not worried about effort to turn it. Im sure it would be fine even if I didnt have PS.This Grant wheel should be fine..
