A Linux Mint operating system takes about 15GB and grows as you install additional software. If you can spare the size, give it 100GB. Keep most of your free space for the home partition.

Is 32GB enough for Linux Mint?

32 gb is fine if you are not adding tons of files. Probably 5-6 gb after installing Mint, with over 20 gb left or updates and a few files. Thanks. Just placed my order for the 32GB thumb drive.

Is 10gb enough for Linux Mint?

The short answer to your question is yes, some but not a lot. You will just be limited with the amount of data you can have in your /home directory. If you plan on collecting the top ten full length movies in there, forget it. A fist full of documents, a few songs, and a few pictures, you are good to go!
