I have 280 Gb of storage on my laptop and i am installing ubuntu on my laptop and i plan on utilising the full space and i wanted to know that the partitioning should be like with the exact space that should be alloted? please help me figure out what the partitioning should look like .

i was planning on going with 60 Gb for /root and 10 Gb for swap and the rest for home and i'm kind-of confused right now cause i am not able to exactly figure out if that should be enough because i don't want to reformat the entire system again . and which one of these should have a larger partition

10GB swap is probably unnecessary if you have enough ram. I used to leave 5GB as swap, a decade ago for an entry point if the system ever failed and I needed to install to that space. you can put home and root in the same partition. which is what happens anyway if you dont select the advanced install option.

You've not said if you're asking about Ubuntu Server & Ubuntu Desktop, as that would be the first detail I'd consider. I say 60GB for / is overkill (*and I like to bloat my desktops more than most I believe; 32GB is my preferred minimum but I'd likely use 40GB if you've loads of disk space, not more though!*) but how you'll use the box will determine what size should be, and you've not said! For *swap* I'd consider your RAM & what you'll use the box for, so I have no idea given the details you've provided.

re: Swap... If you're only installing a single OS on your box, I'd just use a *swapfile* (no swap partition), which will means yes your / should be increased by whatever you want the *swapfile* size to be, but I'd use that over swap partition. I still use *swap partition* on my current system, plus others - but that's because the space can be used by whatever OS I'm using (ie. *I don't have 4 swapfiles on my 4 OSes on this box*). Swap files are similar; and KISS (*Keep it Simple..*) is usually best. You can change partition sizes if you need to anyway; so don't stress about it.

FYI, here's the [official tutorial](https://ubuntu.com/tutorials/install-ubuntu-desktop) to install Ubuntu. Note that manual partitioning isn't addressed because it's simply not necessary for the overwhelming majority of installations. If you don't already have a specific use case for needing separate partitions, don't worry about it. There's a lot of anecdotal and outdated advice about partitioning floating out there. In general, it's best to adhere to official documentation unless you have a special needs case.

Please be aware that `/` is the ROOT partition, where as `/root` refers to something very different (it's a user directory for the root user). (Maybe helpful in understanding Nmath's comment; you need `/` but not `/root`)

Also worth reading, [How large should I make root, home, and swap partitions?](https://askubuntu.com/q/21719/1165986). It's an oldie, but the accepted answer there is still useful today.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
