With the feedback and requests we got from our Best Linux Distros for Gaming list, we had to do another list of the best lightweight Linux distros. Actually, some of them fit both our categories. Sure, there are other similar lists our there, but this one has up-to-date info and we’ve personally tried and tested (almost) every distro on our old laptops. It took us 7 months to compile this list and a few weeks to update it with new data! We’ve seen new lists that included distros with their latest update being in 2005. Come on, how is that distro still relevant and good in 2019? And don’t get us started on how each list is just a rehashed version of the same 5 distros. We purposefully included many distros in our list so you have more options to choose from. All distros are free and can run on ~512MB RAM or less. If you’re feeling overwhelmed, just pick any distro.



You don’t have to throw away your old PCs and laptops. Install a lightweight Linux distro on them and they’re as good as new. Lightweight distros don’t even have to be used on old hardware. You can install them on some bleeding-edge hardware and get the ultimate performance. Most distros are portable and can run on a Live CD/USB, without a hard drive. Why should you use other OSes full of bloatware and unnecessary stuff when you can use a perfectly fine Linux alternative?

Anyway, before we go on with the list, a few quick tips on how to choose the best one for you:

How to choose the best lightweight Linux distro for you

These guidelines should help, but if you’re feeling overwhelmed, just pick any distro from the list below and you’ll be fine.

Any Linux distro is better than Windows/OS X when it comes to old hardware. Linux distros and the software that runs on them are far more optimized and compatible with old(er) hardware. If you’re using Windows or OS X and it “feels slow”, switch to a Linux distro. You’re guaranteed to see an improvement in performance. Some older versions of Windows and OS X are fast for older hardware, but they don’t get any support or updates, unlike all distros listed here.

Some older versions of Windows and OS X are fast for older hardware, but they don’t get any support or updates, unlike all distros listed here. Choosing the right lightweight distro will depend on what you’re going to use it for . Some distros are optimized for certain activities, ie. servers and gaming. Are you going to use it for everyday browsing? If so, have in mind that websites have evolved and although the browser and OS itself will perform better, the websites can still be bloated and slow down your Linux. If you’re going to use it for random office tasks like word processing, spreadsheets, or presentations – the lightweight Linux distros will work just fine. Maybe you’d like to use your old laptop as a media device and watch movies on it. You’re good to go, as long as the movie itself is not a full Blu-Ray rip.

Another guideline is how much you’re willing to sacrifice. How much OS features do you really need? You don’t really need all that fancy UI animations and 3D stuff. Some Linux distros do have great modern UIs, but they do require better hardware.

You don’t really need all that fancy UI animations and 3D stuff. Some Linux distros do have great modern UIs, but they do require better hardware. Previous e xperience is another big factor you need to consider before you choose a lightweight Linux distro. Are you a beginner? Then don’t use Arch Linux. Have you used Ubuntu before? Then get a lightweight distro based on Ubuntu. Got used to the Windows XP interface and want something similar? Sure, we have the perfect distro for you.

Then get a lightweight distro based on Ubuntu. Got used to the Windows XP interface and want something similar? Sure, we have the perfect distro for you. Pro-tip: do a bit of research for your hardware and see if the distro supports it. It most likely will, but just to be sure, you can do a quick google with your hardware model and the distro and you should get some results. Most distros can run on a cheap USB flash drive – you don’t even need an HDD/SSD. This is often referred to as a “Live CD/USB”. We’ll include a ‘minimum hardware requirements’ for each distro, so you can check if the hardware stats you have will support the distro. Most of these distros can run perfectly fine on a Raspberry Pi. Shop for Laptops, USB Flash Drives, and More at Newegg. Go to Newegg
