Wire gauges?

Forum: Jewelry Making Materials

Hi – I’m fairly new to wire working. I enjoy working with thicker gauges.

I’m finding that the copper wire I’ve been buying [from Amazon] is often times a smaller gauge than what I’ve ordered. For instance: I ordered 16 gauge copper wire and it measures as 17 gauge in my round gauge measuring tool. The 12 gauge measured at 13g. And yesterday I received what was supposed to be 10 gauge copper wire and it measures as 12 gauge. It’s not a big deal to me if it’s off by only one but I was surprised to get 10g copper wire that measures as 12g.

I have no idea how wire is made. Maybe this is just how it goes?
