Unfortunately it is not possible at the moment. Its been requested before, but might introduce bugs and I'd rather keep the existing functionality as stable as possible
A workaround would be to run multiple instances of SAT, with different layouts, each layout having the size you want, and then using custom site profiles to match a specific game/table type. Something like:
SAT 1:
Layout 1 w400 h300
Custom site for ACR matching $0.01/$0.02 blinds cash games
SAT 2:
Layout 1 w900 h500
Custom site for ACR matching $5 sngs
Something to that effect might work
