Can i adjust the size on the seating chart on this site?

I just started Wedding Wire on my laptop instead of the app on my phone and found a seating chart where I can add table and assign guests to them. Is there a way to make the tables smaller or make the graph bigger? I will have 33 tables at my reception and was hoping to be able to add them in the graph thing to be set up exactly how they will be at my venue but I can barely fit 8-10 tables.
