I am looking for some new tires and would like to get some that has a little more height in them and a good AT tire... i found some good tires i just want to know how much higher my truck would be.
I have the stock 275/55/20 road tires that gmc puts on there trucks and now im looking at the general grabber AT2 tire in the 305/50/20... i need help from the OB on some specs and how much higher my truck would look....it has a leveling kit too soo im not worried about rubbing

get rid of 20" wheel. No need for that on a truck.

31.91 inch diameter on the stock tire
32.01 on the 305/50r20
so absolutely no difference, well .05 inches if you want to be technical.

Question: I don't know shite about tires (I feel like a women). What size can I fit on my truck and how do you figure that out. 265/70-18 is what I have now. What can I go up on while keeping factory rims?
Someone educate me.

I wouldn't recommend either of those sizes. I would recommend a 275/60/20 Cooper LTZ. They are just under 33" tall and about 11.5 wide. They are not E rated and can be had for cheap. They have a nice tread design and last a long time.
Ignore the people telling you to get smaller wheels. You paid a premium for the 20s so keep them. By the time you buy new rims you could have bought 2 sets of tires and still look better. I highly doubt you will be going rock crawling or even mudding since you are interested in those sizes, again, so smaller wheels is not necessary.
Eta: if it is a F150 no leveling kit or anything is necessary for the 275/60/20 to fit. The LTZ also comes in a 275/55/20 of you really want that size.

I just bought some cooper zeon LTZ's 275/55/20 and are pleased with them. Look into those.

Also OP, if you want to know what a tire size means, it's in millimeters. The first number is the width, the second is the aspect ration (the thickness of the sidewall as a percentage of the width) and the last one is the rim size.
275/55/20 is 275mm wide with a .55x275mm thick sidewall.
You can convert to inches and add the rim size to 2x the thickness of the sidewall to figure out tire height and width, but I just use the tire size calculator I posted cause it's easy and I hate math
