How is calculated the size of Linux on hard drive?

Hello,

If I use command:

Code:

$ df -h /

I will get 2.2GB as answer on clean, just installed Linux. But, what that really means? Is this just a sum of all installed packets?

Code:

$ dpkg-query -W --showformat='${Installed-Size}\n' > sizes
$ awk '{s+=$1} END {print s}' sizes

Result is: 1554MB. Where are missing 700MB? How to find it?
