New dual boot setup - storage options?

[keys_au1]

About to try a dual boot for the first time ever and I am vexed as to how I should set up the storage. Windows 11 will be pretty much general pc, internet and games, Linux will be the audio DAW drive and I have a 1tb drive for storage. Windows/linux drive is 512gb.
Was thinking 200 gb windows the other 300 Linux and then all active data files on the separate drive.
Thing is I am unsure if I should allocate a data partition (home) for Linux make the 1tb drive purely backup and storage and reduce W11 size a bit, OR make W11 bigger, smaller Linux using the separate data drive….

Is there some standard sizing protocols for dual boots?

Nope.

Was thinking 200 gb windows the other 300 Linux and then ...

Last machine I made dual-boot was a Win10 machine with a single ~500MB disk.
I also wanted 200MB for Windows (allowing still for some free space and a little growth) and the other 300MB for Linux. So I started the disk manager of windows to shrink the partition, but it only let me shrink it to 300MB, stating there was a file which it could not move. Oh well...

Use separate drives for the two OSs. I've heard way too many reports of Windows updates bricking people's Linux installations on single-drive dual boot setups to advise otherwise.

Dual boot is never a good option. Use separate drives.

I generally don’t use Windows as i have never really got on with it, but I have 2 MacBooks and have thought about resizing the hard drive on the older one to dual boot with Linux.

What I’ll probably do is make a Mac partition about one third of the disk capacity, create Linux partitions to take up another third, and create a partition that both operating systems can share.

I figure I can always do some resizing later if I need to.
