I made a bootable USB thumb High Sierra install disk on an 8GB drive. Apple recommends a 12GB drive. This is not with the new file system though, no solid state drives here. I have over 2GB free after writing the USB.

Where does it say the drive has to be 12 GB? I thought 8 GB was all that was required.

However, the final install is almost 12 GB. My clean install on my 2010 iMac is 11.3 GB.

Apple said:
Mount the USB flash drive, external hard drive, secondary internal partition, or other storage media that will contain the install media. Make sure that it has at least 12GB of available storage space.

It comes from Apples official support page on making a bootable installer for macOS.

I was reading at Apple Support on making a boot/install USB and it was there. I really only want it to run disk utility on real boot, in case.
