Is your Ubuntu 32-bit or 64-bit OS?

As a Linux user, it sometimes becomes important to know whether you are using the 32-bit or 64-bit version of Ubuntu on your system. The question is how to check the appearance of your operating system (OS), as well as the architecture of the underlying processor.

This lesson will answer the following questions for you:

  • Am I using a 32-bit version of Ubuntu or a 64-bit version?
  • Am I using a 32-bit version of Ubuntu on a 32-bit processor architecture?
  • Am I using 32-bit Ubuntu on a 64-bit processor architecture?


  • Am I using 64-bit Ubuntu on a 64-bit processor architecture?

First, let’s start by understanding what 32-bit and 64-bit processors mean. In the early 90s, processors had 32-bit specifications; This means that the data bus was capable of transmitting 32 bits at a time. With the development of hardware technologies, the capacity of the data bus has improved, and now they are able to carry 64 bits at a time; they are called 64-bit processors. These fast processors can run twice as much as their predecessors.

32-bit processors can only support 32-bit operating systems, while 64-bit architecture can use both 32-bit and 64-bit operating systems. To make the best use of advanced hardware technology (a 64-bit processor), it is best to use a 64-bit version of the OS (in our case, a 64-bit Ubuntu OS).

How to check if you are using 32bit or 64bit Ubuntu?

Ubuntu provides you two ways to test the taste of your operating system:

  • Using Ubuntu GUI
  • Using Ubuntu Terminal

Note: we are launching this Ubuntu 18 tutorial.

Using the graphical interface

To check if you are using a 32-bit or 64-bit Ubuntu operating system:

  1. Open the system settings using the following two methods:
  • Click the down arrow located in the upper right corner of the screen. The following window will open:

Now click the settings button located in the lower left corner of the window.


  • Open the Settings app from the Ubuntu app menu as follows:

Open the Settings app

The following settings window opens, displaying the various system settings as tabs. The default tab is open for Wi-Fi.

Settings window

  1. Click the Details tab in the left pane.

In the “Settings” window, the following “Details” tab will open, and information about the program will be displayed in the right panel:


Here you can see information about your system, including the type of OS. This field indicates whether you are using a 32-bit or 64-bit operating system.

Note. Please note that this window will not provide information about the underlying architecture of your processor. To view you need to use the command line (Terminal)

Command line usage

You can also check the taste of your Ubuntu OS through the command line – Terminal.

  1. Open Terminal.
  2. Use the following command to get processor information from the sysfs and / proc / cpuinfo files:

$ lscpu

This command will display the following output:

lscpu team

The following entries are important for checking the type of OS and processor architecture:

Architecture: This post will tell you about the architecture of your processor; x86_32 means you have a 32 bit processor and x86_64 a bit means you have a 64 bit processor. In the above output, you can see that it is a 64-bit processor.

You can also use the following command to display only your processor architecture:


Processor Modes: This post talks about how Ubuntu works on your system; 32 bit means you are using 32-bit Linux, 32-bit, 64-bit means that you are using a 64-bit OS. In the above output, you can see the “32-bit, 64-bit” operating modes, because the 64-bit processor architecture can work with both of these variations.

Now you can know exactly what your taste and architecture of Ubuntu is!
