Need Advice for Bootcamp Partition

I've been thinking about installing windows using bootcamp on my 2017 21.5 inch imac currently running on macOS Big Sur which has a 1tb SATA Disk. I still have 725 GB on it. I'm installing windows just to play valorant since its not available on mac. How much space should I give my mac os and how much should I give Windows? Thanks!

Install Windows 10 on your Mac with Boot Camp Assistant - Apple Support recommends 64GB as minimum required. I recommend 256GB-384GB. From the link...


  • When Boot Camp Assistant asks you to set the size of the Windows partition, remember the minimum storage-space requirements in the previous section. Set a partition size that meets your needs, because you can't change its size later.


If you need to enlarge the partition later, you will need to remove and re-install Windows.


This is from a 2018 Mini.
