Hi

Under the configurations page it gives dimensions and sizing of the most common configurations.

If you are interested in the tarp with beaks, contact us. We are trying to make the Lil bug out, a little easier to understand so we actually reduced options at the moment. The ordering will get easier early in the new year.

Sq footage with tarp + vestibules probably as a guess about 75 - 80.
