I don't know how drop bars for gravel bikes and the like compare with road bike bars (I suspect they're wider and shallower)
As a rule they generally come wider as standard, however, I've replaced my standard 460mm wide bars with 500 wide bars, measured at the hoods.
They are also flared much more than normal gravel bars, so 24 degrees of flare on mine, meaning on the drops they are wider again.
I'm just a slim built, average height bloke, but I find these wider bars super comfortable, especially when off road touring. They also give me great control at low speeds off-road.
