Does anyone know how to measure or determine the wire size. I have

Micrometer.
Vernier caliper may also work.
Either under $30US.

I don't believe anyone uses vernier calipers anymore. I've got a Helios
dial caliper made a long time ago in Deutschland, but nowadays a caliper
with a LCD is probably a lot cheaper.

I'd like an LCD one of course.

You should shell out the $20 or whatever then (or $100 and get a
Mitutoyo or other brand name with a bit better "feel"). I use mine all
the time- for rough (0.001") width, diameter, inside diameter
(rougher) and depth measurements. A micrometer is useful for precision
measurements, but less necessary for an EE.

Unfortunately, $20 is quite a lot of money at the moment :/

Mm.. 'kay. Hope things get better fast for you.

I don't have any real need for it - I've got a 0-25mm micrometer, and
the plastic caliper fills in for the rest.

I don't have any tools that can maintain that sort of tollerance anyway,
so my need is less.

You don't have a file? ;-) Just double-checking lead pitch etc. is
worth a lot by times.

True.
I don't really have that much that I need to hold accurate tollerances
for anyway.

The file is a much underestimated metalworking tool.
