Of course, this is not 100% but it will get you close enough...

Each file in the db uses about 300 to 350 bytes. So you could guestimate
the size of your new DB by  counting the number of files for each node
that is going to be on that server, multiply that by 350 and take a factor
1.5 more so you can grow a bit and you have some room to spare in case
your tipical files require more than 350 bytes per file....
