Determining Rear Lift Height?

I have a 2019 Off Road, on Icon RXT Stage 2 leafs. Getting ready to order custom springs as I'm throwing more weight at the truck.

From top of axle housing to bottom of frame I'm just at 11" or just a hair under. Picture attached. Guessing this puts me just over 2" of lift.

But I need to know exactly how much I'm lifted over factory. Is there a way to measure to determine?

 

Center of hub on wheel to fender. Stock front is about 21" stock rear is about 22"

 

There should be sticky for rule to measure and report lift. Above recommendation seems to be the measurement technique around TW. I wonder what Icon uses to report their level of lift? Many of us record/report measurement from ground to various body parts, which is helpful only if you want to know where your empty bed ends up (which can surprise you).
