Depends on the wood, the screw, what the screw is going into, how tight you do it, countersunk or pan head, if it’s solid timber are you close to the end grain or long grain…
If I’m putting boxes together I set the screw in 10mm, usually slightly more than half the thickness of the board it’s going into the edge of. Mostly birch ply, valchromat or hardwoods, and usually a counterbored hole that will be plugged.
