Storage use of Ubuntu touch?

[vadrian89]

I am looking to buy a Nexus 5, to install Ubuntu on it(and hopelly start developing some apps for it) and I want to know If I should strongly buy a 32gb storage version or 16gb is plenty enough.
So to put it more straight, how much storage does Ubuntu Touch uses?

Here you have exact numbers:

phablet@ubuntu-phablet-bq:~$ df -kh

udev 479M 4.0K 479M 1% /dev

phablet@ubuntu-phablet-bq:~$ sudo du -sh myRoot

phablet@ubuntu-phablet-bq:~$ df -kh .

/dev/mmcblk0p7 4.4G 3.7G 534M 88% /home

The 1.9 GB below 'myRoot' is a complete Debian in a change root file system for developing purpose.

Thanks, I managed to buy a second-hand 32GB(a bit abused to be honest) but I bought it for aprox 65 euros which I think it's ok for the state in which is it.
It seems Ubuntu is using aprox 16GB total, for me.
