How much physically bigger is 12 AWG vs 16?

I have 16 AWG speaker wire running my speakers now. My back speakers have about 20 feet of wire each but I have it under carpet in a straight line. I want to run wire along my wall molding because I am having problems with the runs under the carpet (carpet tacks etc.) Along the molding will make it about a 50 feet run. I was thinking of using either 14AWG or 12AWG. I want to order online but want to check how physically big the wire is before I buy it.

How much physically bigger, with cover, are 12 and 14 vs 16? Anyone know of any web pictures with them side by side?

I don't know if the thickness of the skin is proportional to the wire size.

AWG is a sizing standard. Different manufacturers use different thicknesses for the insulation covering the wires, there is no standard for that.

I would contact the support folks at Monoprice and/or Blue Jeans Cable, they should be able to give you exact diameters of the various gauges that they offer.

The sheathings are not standard diameter between manufacturers.

They're just slightly different with of course the 12 being a little bigger. Again though, the difference isn't that great.
If you don' mind 18 awg, they sell something called tapewire. I use it. It's flat, adheres to walls and ceilings, and can be painted over so it's barely noticable.
I bought mine several years ago for my rear pair and 18 was adequate. They may offer higher gauges now. Just google.

BTW, it's a log scale. A decrease of 6 AWG doubles the diameter; A decrease of 3 AWG doubles the wire cross-cut area.

Thanks that chart is helpful at showing them against each other.

I think you have your answer so what I say will be redundant, but I will say it none the less.

Generally we go by Cross Sectional Area -

12ga = 3.31mm² (59% larger that 14ga)
14ga = 2.08mm² (59% larger that 16ga)
16ga = 1.31mm² (59% larger than 18ga

But rather than relative size, you want to consider size relative to distance and the speaker impedance The longer the wire, the thicker it has to be to maintain the same resistive loses.

FYI: % Signal Loss for Speaker Wire Length

Post #2 has 1%, 2%, 3%, and 5%. With 5% being the common maximum.

For example, here is 16ga wire with 5% loss to 4 ohms, 6 ohms and 8 ohms -

4 ohms - up to 25 feet
6 ohms = up to 37 feet
8 ohms = up to 49 feet

Most will use 14ga (2.08,mm²), just to give a degree of reserve. Though it is a huge reserve. From memory, 14ga wire will susstain 300 watts all day long, it has a maximum working peak of about 1800w and a failier peak of about 8000w. So, it is pretty substantial.

For 14ga wire we have the maximum distances at 5% -

4 ohms = 40 feet
6 ohms = 59 feet
8 ohms = 79 feet

Though it is recommended that you do not exceed 50 feet unless you absolutely have to.
