The rule of thumb that I have seen is "3 times the high pressure flow capacity of the pump".
This may seem like a lot and IMHO I would want to error on the high side. You do not want to pump to suffer from cavitation and you want enough oil to ensure it stays cool during use.
Maybe the unscientific method would be to say "I have 'rule of thumb-d' I need this much and there seems to be room for a (calculated plus 25% bigger' tank just about here ...". A 'too big' tanks are not generally that much more expensive than a smaller tank ... both initially or to fill ... and do not create problems the same way a 'too small' tank will.
But that is just my opinion,
