Try uysing the sump calculator to figure how big you need it to be when the power goes off.

As for designs, the only limit is your imagination. I prefer the old standard 3 compartment flow through design but here are some ideas:

Thats good start. Its really gonna be all about what your tanks needs are. Like fishdoc said the standard 3 compartment is a good design. But also things to consider might be What size skimmer will you have ? (the footprint) Are you gonna run any type of reactor? Do you want to run a refugium in your sump ? The sky is the limit, well actually its the size of your wallet. Just take your time and have fun !
