How to determine doorbell wire gauge

I'm going to install a Ring doorbell, but I'm moving the location of the wired doorbell about a foot away from its current location. I need to add a foot or so to the doorbell wiring. I've read that doorbell wire is 18-, 20-, and 24-gauge wire. I hate to ask what to some might seem like a dumb question, but how do I confirm the gauge of the wire that's currently installed? The house was built in 2009. I don't think there's enough there to read anything on the wires. Thanks.

The smaller the number the thicker the wire. If you're not sure always go thicker. It can handle more current. For a door bell wire system it's no big deal.

I normally use 18ga for doorbell (and thermostat) wiring.
