Educated guess a 10 1/2 X 11" Actual size would depend on the application.
Diameter is approximate and usually just follows pitch.

the motor is going to be used on a 1987 grumman 16' aluminum deep v boat, with 3-4 people and 200 pounds of gear. mainly fishing , camping and hunting. i've been told the diameter should be 10-13/100 with a pitch of 12???? i'm new to this so any ideas would be appreciated.

Is that suggestion saying a 12" is standard?
With the load your carrying I would drop down from standard 1" .
If 11" is standard as I suspect I would go down to a 10.
If a 10 turnsout to be too light at least you can use it by watching the rpm if the 12 turns out to be too much yoiu just shouldn't use it for an extended period.
As far as diameter pick your pitch the correct diameter for that particular prop will follow.
No need to worry about diameter unless someone can tell you specifically why its needed.
