What size drill bit to use for pre-drilling?

I'm connecting two 2 x 4 drywall screws withe together. I'm using 2.5 "screws. Go through all the 1.5 "of the first 2x4 and 1" of the second 2x4. My question is: a) what diamteter size drill bit should I use to b) how much should I drill deeper? Any general rules, tips and tricks that you go for when pre-drilling? thanks

if they screw the screws should not having to pre-drill. doesn't matter the length of the screw is the diameter. Usually has about 1 / 16 less than the diameter of the screw thread small
