Same AWG # but different wire size??

I'm in the process of relocating a power outlet and have to extend the wires. I took note of all the sizes by reading the nomination written on the existing wires, went to the store and bought wires with the same AWG # but they are actually smaller!? How can that be?
Any help would be appreciated.
Thanks in advance.

Advances in plastic technology have allowed manufactures to produce wire with thinner insulation. The actual metal core of two wires of the same gauge will be exactly the same diameter.

What size circuit breaker is this, and what size wire or cable did you buy? What size wire or cable are you extending?
