Average trailer length & width

What is the typical length and width for 1980’s-2000 two bedroom trailers?

1980’s: Mostly 14x70 and 14x60,
16 wides and 80 long homes, starting in the late 80’s.

1990’s is a mix of 14 wides and 16 wides. And mostly 70 or 80 ft long.

2000’s mostly 16 wides, any size can be made though…

I appreciate the info
