Does spoke length change with rim width?

[crud]

I would think keeping all other variables the same except going to a wider rim, the spokes would be the same, correct? Or are the spoke holes spread out slightly more on a wider rim?
I am asking because I'm looking to order spokes from MikesXS, and they claim the kit I'm looking at fits WM2(1.85), but no mention of WM3(2.15) or WM4(2.5).
I am basically just trying to order spokes for my stock drum rear hub, and a 18" x 2.5" WM type rim.

Thanks for your help!

Hi crud,
Even if the spoke holes are spread further away from the centerline on a wider rim it can't be by much.
I doubt there'd be enough difference to make the job need longer spokes.
Nah, I just don't see it being a problem.
