Hi guys, I am re-installing Fedora, and for the first time I will now have a separate partition for / and /home. How much space would you recommend for the root partition? I'm installing Fedora 20 with Gnome incl. all standard developer, office, and internet software but I won't have any games installed. 15 GB enough? Do I need 25GB, or even more? The installer suggested to have 51 GB (out of my 250 GB SSD). I think that's too much and I'd rather decrease / and increase /home.

What's your thought?

15 or 20GB should suffice, i currently use about 10.2GB in my root, I've upgraded my fedora twice (F18->F19 and then F19-F20) installed plenty of software etc.

Please update your answer, with newer releases better suggestion is 20 or 25GB, 15GB is really on low side. As soon as you start adding software packages with 15GB root partition you run out of space really soon..

Summary of the answers given so far:

  1. 15-20 GB
  2. 10-20 GB
  3. 16 GB (http://www.mjmwired.net/resources/mjm...),
  4. >20 GB (Installation Guide F20, Chapter 9.14.5),
  5. 10-14 GB (User @alfC)
  6. 20-25 GB (user @valentt)

For me, 15 GB is sufficient space for the root partition but in order to have some spare space and feel really comfortable I sized my root partition to 20 GB.

This information should valid for Fedora 21, 22, 23, 24.

I used 15GB for Fedora 22 and I regret it, not I'm always having low disk space messages. At least 20-25GB to be safe.

I agree, 15 is rather on the lower end of what was suggested here. It all depends on what you want to install on top of the "regular" desktop workstation. Stuff like Latex, games, JDK IDE, ... can be intense. Meaning, you can be totally fine with 15 GB (I only have 9GB out of 18 occupied) but yes, 15, 18, or even 20 GB may be too small but for most users it will be sufficient.

I have a fresh install of Fedora 20, it uses 8.1GB.

Big packages are Gnome, Evolution, Firefox, Thunderbird, TeXLive Full, GCC, Open Office.

Update: I have Fedora 21 it uses 13.7GB including the above packages plus Mathematica.

Update 2: I have had a heavily used Fedora 22 for more than one year, and it now uses 27GB, /usr -> 20GB, /var -> 6.8GB (in which /usr/local/Wolfram -> 7GB, /usr/share/texlive -> 2GB, /var/log/journal -> 4.4GB and /var/cache/PackageKit -> 1.8GB ).

It is enough. I used only 10-20GB in root(/).

You can always adjust the size of partitions later if needed.

That's true - I'm just a little afraid of messing around with re-sizing encrypted LVM (due to lack of knowledge...)

go for 50GB or even more, sooner or later you'll discover you are running out of space. Modern HD have plenty of space.

A root partition (3.0 GB - 5.0 GB) This is where "/" (the root directory) is located. In this setup, all files (except those stored in /boot) are on the root partition. A 3.0 GB partition allows you to install a minimal installation, while a 5.0 GB root partition lets you perform a full installation, choosing all package groups.

Hi, I have now installed Fedora20 and not yet set up the system entirely but I can already say that 5GB would not be enough for my root partition using a "full" Fedora with Gnome, Evolution, Firefox, Texlive, Libreoffice, Virtualbox. It might be enough for a minimal system though. Your link refers to Fedora 16. The installation guide for newest F20 recommends at least 20 GB (Chapter 9.14.5).

500MB is plenty. My root partition is 500MB, and I have 365MB free. The root partition actually holds very little of the operating system.

500MB ??? It is /boot.

Charles Wang ( 2014-01-10 07:01:29 +0000 )edit

David, this must be your boot-partition (/dev/sda1 for example) mounted to /boot which holds the kernel(s) only.

Florian ( 2014-01-10 14:18:34 +0000 )edit

Yes, that is my /boot. My /fedora-root is 50GB, 5.6GB used. /home is 402GB, 4.8GB used right now.
