Default sump size

How do you know what size sump to use for each tank?
Is there a rule of thumb for size ratio?

Generally the bigger the better. If you can somehow fit a 180G sump under a 10G tank, you should certainly do that.

I never heard of a formula but I've used a 40G sump with my 135G tank and now use 75G fuge with my 180G tank. If I had a house where my sump room would be below (in the basement) and my show tank on the first floor I would hook up multiple refugia possibly exceeding total volume of the show tank.

Yep, as bderen said, the bigger the better, go with whatever you can fit under your tank leaving some elbow room to perform maintenance tasks. Any sump/refugium is better then no fuge at all, even these relatively small hang on tank refugia are somewhat effective and interesting to watch.
There comes a time in this hobby when it's just cheaper to silicone around the windows.

Default sumps size

The formula I have heard is the sump should be atleast 25% of the main tank, but you are right the bigger the better. You can not do wrong by making a sump to big. In this case bigger is definately better, no matter what they say!!!!!!
