I'd like to chime in with an option for % sizes as well as {pixel} sizes. I've currently got three different resolutions I'll be running Realm Works at, and something that looks good on the 24" monitors is going to take up too much space on the laptop's screen (Now I wish I had one of those reversible-screen laptops, so I could use a larger external monitor for myself and let the players have the tiny screen for Player View
).
