What is the minimum hard drive size required to install Sierra?

[dba415]

I have a spare 16 GB SSD and was thinking of installing macOS on there for fun. Will the 16GB of space be enough?

I highly doubt it.

According to Apple's support article, Sierra requires 8.8GB of available storage and 2GB of RAM. But I highly doubt installing on a system with those specs would be "fun".

I have run Mac OS from a 16 GB flash drive, but there is no room for more apps and precious little storage space for files, so another, larger drive is a must. If you have to have a larger drive anyway, why not install Mac OS on it in the first place?
