2X to 4X bigger has been the tokamak rallying cry for 50 years.

You can get away with a smaller tokamak with high energy densities and net energy production if you increase the field strength aswell, I think that was what the FIRE programme was about, building a reactor the size of JET only running it at 10 Tesla instead of three.

The only catch is morepowerful magnetic fields also cost money.
