Angle pull box sizing

[Ponchik]

(2) 3" conduits installed for an angle pull. Allowing for the lock nuts, I calculate the size of the pull box to be a minimum of 13"x13". The 13x13 is not standard so I have to go to 16x16.
Correct?

The 13x13 is not standard so I have to go to 16x16.

Angle pull is 6X the raceway trade size plus the additonal raceway in the row. You also need a minimum of 18" (6X3) between the raceway entries.
