As big as possible! Most sumps/fuges are smaller than the display, but really, if you think about it, the sump/fuge should be larger. Get as big of a sump you have room for. IMO it's better to have a larger sump and have most of your equip. in your sump than to have a smaller sump and have your equip. outside of it. I have a 92 gal. tank with a 54 gal. sump. Small sumps are hard to work with. They just don't provide room to work or room to upgrade equip. Also, larger sump means more water which means more stability.
As large as you can possibly afford/fit in the area provided. I know that sounds obvious but look at what a sump is designed for and it's simple to see the bigger the better.
1. Increased water volume of the sump will dilute pollutants in your tank and help prevent large swings in ph, salt, and heat.
2. A large return section will mean long time between top-offs since your sump water level is the only level in your tank effected by evaporation.
3. Filters, Refugium, Simmers, heaters, etc, all require space.
O and lastly I would suggest a longer sump over a taller sump. The longer the sump the better chance for microbubbles created by the overflow to rise and pop before reaching the return section.
Good Luck!

Yep what everyone else is saying. I have a 125 gal display and 100 gal sump. you can't have a max size. your sump could even be larger than your display which I will end up doing. I will most likely be building a 40 refugium. At that point my out of display volume will be greater then in display volume. Some people have fugiums, grow out tanks, sumps and other stuff.
Agree with the comments above, and also keep in mind that you want to have extra room in your sump for that time when you're not home, your power (return pump) goes out and there is some back-siphoning into the sump via your return lines. Siphon break holes will stop most of it, but you're bound to have some water go back into the sump.
