I believe I used 5x6. Battstat and the weather don't have alignment options so they're just there. Clockr is left aligned and OneSeven is centered. As far as positioning, there's a trick I learned with sizing in LP; i.e. here I placed OneSeven where it is, then placed Clockr above it (above where it is now) then resized it "over" the OneSeven widget, resulting in both widgets being closer together.
