Tinning Wires

I'm ordering a bunch of tinned wire to fit in a PCB that I have. I know the diameter of the hole in the PCB (0.80mm) and the diameter of the various wire gauges, so a 22AWG should fit (0.644mm diameter). If the wire is tinned, though, how much can I expect the diameter of the wire to increase? I might just get 24AWG to be safe, but then I would continue to have this same question!

Thanks!

Since we cannot control your supplier's process, you should be asking them or tell them what is required.

1-50 um.

We can speak of "tinned" to mean "tin plated" or "tinned" to mean solder has been applied to the stripped part of the wire.
