What is the file size of the Ubuntu iso image? I have Limited internet, and don't want to use too much of it. I want to put it on a Disc or USB thumb drive and install it on a unused computer.


These are numbers are taken directly from the iso files I've downloaded. Also if you download your iso from http://releases.ubuntu.com/13.10/ or http://releases.ubuntu.com/12.04/ it lists the file sizes beside the names, in the directory browser at the page bottom.


Ubuntu 13.10 - Desktop X86-64 = 883 MB

Ubuntu 13.10 - Desktop X86-32 = 895 MB

Ubuntu 13.10 - Server X86-64 = 672 MB

Ubuntu 13.10 - Server X86-32 = 658 MB

Lubuntu 13.10 - Desktop X86-64 = 702 MB


Ubuntu 12.04 - Desktop X86-64 = 698 MB

Ubuntu 12.04 - Desktop X86-32 = 701 MB

Ubuntu 12.04.3 - Server X86-64 = 665 MB

Ubuntu 12.04.3 - Server X86-32 = 648 MB

Lubuntu 12.04 - Desktop X86-64 = 697 MB

Kubuntu 12.04.3 - Desktop X86-64 = 707 MB

Xubuntu 12.04.3 - Desktop X86-64 = 712 MB


Ubuntu 14.04 - Desktop DAILYBUILD-JAN-21-2014 X86-64 = 912 MB


According to my Downloads directory, the download size for the 64-bit 13.10 desktop ISO is 904,192 KB (883 MB).


It depends on which image and which release you are downloading. Everything prior to 13.10 hovers around 700MB so it can fit on a standard CD. 13.10 is a bit larger around 900MB. I believe Canonical aims to keep the LTS releases under 700MB.

  • 4 years later… It's not. What a shame: Ubuntu Desktop 18.04 LTS ISO image is 1.9 Gbytes. That is, it doesn't fit into a CD, and anyway it's about half the full capacity of a DVD, wasting space. There's a mini.iso which is really mini, less than 100 MB, of course it fits into a CD, wasting again very much space. It seems it doesn't exist an alternative (if you rule out USB). Debian offers both obvious choices in a reasonable way: a full CD (650MB) and a full DVD (4.4GB), the logical, smart choices. – ShinTakezou Nov 26 '18 at 20:59

32bit: 0.713867 GB

64bit: 0.71582 GB

Information from ubuntu 12.04.4 LTS


It says on the download page! Almost every browser including yourse shows how big is the file you are downloading!

    Could you perhaps point out where it says? It would be cool if you provided instructions to tell without actually downloading something. Right now this is hardly an answer. – Seth Mar 5 '14 at 21:48
  • @Seth I would but it depends which file you want to download. – PriceSave Mar 5 '14 at 21:53
  • Try to make a good answers that covers all that nevertheless. (It doesn't have to be a huge list, take this answer for example: askubuntu.com/a/430045/44179) – Seth Mar 5 '14 at 21:54
  • I'm with @Seth on this one. I'm looking right at the download page and I don't see file sizes listed anywhere: ubuntu.com/download/desktop – Aaron Mar 5 '14 at 22:20
  • @BryceAtNetwork23 cdimage.ubuntu.com/lubuntu/daily-live/pending always shows file size just like your browser when you start to download ANY file – PriceSave Mar 5 '14 at 23:16

All of the Ubuntu desktop downloads are under a gigabyte. If you want to know the megabytes that each edition of a desktop installation of Ubuntu is, here you go:

  • Ubuntu 13.10 - 895 MB

  • Ubuntu 13.10 64 bit - 883 MB

  • Ubuntu 12.04 - 731 MB

  • Ubuntu 12.04 64 bit - 733 MB


All the releases of Ubuntu along with its official derivatives are linked at http://releases.ubuntu.com/. Navigate to the particular release you want to download.

Suppose you want to download the images for Precise (12.04), you would go to http://releases.ubuntu.com/precise/. This page contains all the latest images available for download for 12.04 in a table showing the names, last modified date, size and description for each image. "Size" is the column which answers your question.

Which image am I supposed to download?

* in the following list represents the release of Ubuntu (eg; 12.04.4 for the latest point release of Precise)

  • For Desktop 32-bit: ubuntu-*-desktop-i386.iso
  • For Desktop 64-bit: ubuntu-*-desktop-amd64.iso
  • For Server 32-bit: ubuntu-*-server-i386.iso
  • For Server 64-bit: ubuntu-*-server-amd64.iso

release page for Precise

We can see that Desktop 64-bit and 32-bit are about 733 MB and 731 MB respectively and Server 64-bit and 32-bit are 679 MB and 661 MB respectively. (Here 1 MB = 1024 KB, so if your ISP calculates data as 1 MB = 1000 KB, do the maths as necessary).

Tip: If you want to save as much data as you can while downloading and already have an image of Ubuntu previously downloaded, you might want to use zsync to update the iso.
