I'm not an LVM user so I live with my partitioning for years.
I would opine that 10GiB is rather risky for a root partition
(with /home separate). My smallest root partition, on an old
laptop that I've been using since 2009, is 15GiB (74.5 GiB drive).

I'm not a DE user, which might reduce usage a little, but /usr
alone ranges from 8.4GiB (jessie on that laptop) to 10.2GiB
(wheezy, as it happens, on a desktop). That's without giving
any consideration to /var and /tmp.

I would find that rather risky, so I have a "proper" separate,
encrypted /home that ranges from 50GiB (laptop) to ~400GiB
(desktops)—basically, the rest of the drive, though one laptop
gives a fair amount of space over to a W10 installation.

Bear in mind that were you to make your root far too large, it's easy
enough to borrow some space by symlinking to, say, /var/local/myname
(for unencrypted, less sensitive material).

Cheers,
David.
