Now that's something that is very ambiguous. A whole bunch of considerations, primarily what tire you're using as all makes and models are not created equal and how good your perceptions/ muscle memory are/ is.
It's like how a mechanic is able to easily gauge how much torque they applied to a fastener by hand without using a torque wrench. It takes time.
A good way to start is to find a PSI you're good with and checking how firm that is.
OR you just stick to a magic PSI/ bar number with a gauged inflation device.
