Thumb drive Windows 8 OS

[starshield10]

I have a 4GB thumbdrive that I plan on making bootable for the Windows 8 OS. It's 3.72 Gb to be more specific, my question is will this be enough room for me to use as the OS booter?

That's the size I used and worked with 7 all the way to 10 so far. 64 bit pro versions on all of them which are bigger than the home isos.
