You can use an online calculator, such as this: https://spokelengthcalculator.com/
If your hub and rim specs aren’t provided, they can be readily measured if you have the hubs ans rims

Thank you.
Do you know about building these?
Wondering if I have to put an offset in and the hubs mention through axle and 6 hole rotors but they’re not. Assume the hub is the hub

If you plan to build yourself, it might make sense to get some background info on wheelbuilding, such this site I like: https://spokecalc.io/articles.php
You will have to dish the wheel in front if it has disc brakes, The back wheel also needs dish ("offset" of the rims from being directly between the spoke flanges). You also need to choose a lacing pattern (3 cross most common on MTB). The type of axle has no direct effect on spoke length. It is all about hub measurements (width, position of spoke flanges, and diameter of flanges)
I build my own wheels. It is not too difficult, but one needs to understand the process, make careful measurements of the hubs and rims to get accurate spoke lengths, and then develop a process for truing the wheel. Patience helps. To build your own wheel, you will need some sort of truing stand (doesn't have to be top of the line if you use it carefully), a spoke tension meter, and spoke wrenches. I also like using a dishing tool.
Hope that helps

Many thanks for the detailed reply.
Makes sense that. I’ll get to the rims I haven’t built any for a long time so be good to get back into it.
Will get the basics to start off with. Have four to build at the moment.
I’ll pay careful attention to the offset as I’ll need to make sure I don’t mess that part up.

When I build wheels, I keep an eye on dish early on, and incrase spoke tension evenly while trying to keep dish close to balanced. I think you can end up needing to do a lot of unnecessary work if spokes are tensioned and dish is way off
