Width by years and size?

[rwrussom]

Somewhere there needs to be sticky with dimensional info. Dimensional questions come up all the time and often remain unanswered.

Best I can figure at this point:

Pre '69 7'-6" was standard on all legnths

'69 forward

less than 25', width was and is 7'-6"
25' and more, width was and is 8'-0"

At some point wide bodies came in that increased width to legal max 8'-6"
which ones and when?

Please confirm or correct and lets get a definitve post. Then we can work on the lenths.
