geez.. nice. a sump is really meant for your filtration equipment.. and any extra water volume. I say get as big as you need/can.. there is no magic number. you want all of your stuff to fit (skimmer, etc) and it needs to fit under you tank... and it needs to be set to hold any overflow (in case of a power outage, for example).. otherwise, it doesn't matter.

Really based on the height it needs to travel and how much waterflow you want turned over.

There are more variables to consider than simply basing a sump based on volume alone. What do you plan on using your sump for? Do you want a large refugium space for biological filtration , or do you plan on using mainly mechanical filtration? These are some things to consider.
