Jet size is related to the chemical composition of the fuel, as the air to fuel ratio is different with different jets. Smaller jet uses more air.
Some stoves claim that one jet works for both white gas and kerosene, example Optimus Nova. But I have had rather poor luck with trying straight kerosene in my Nova.
