I have all my 900 charts in 2 2" binders, and 1 1" binder for the common destinations. I personally put all the airport directory pages in front of each airfield. Alphabetically, I have A-N in one binder, O-Z in another plus charts. My 1" includes ATL/DFW/MEM/MSP//ORD/DTW so that takes up half the space, but the rest of the places I have been so far fit in there as well.
