BAZIC 3" White Slant-D Ring View Binder w/ 2-Pockets, Case of 12 (3175-12)

my binding comm presents how ring binders are measured these binders are all labeled different sizes from five eight seven inch to five inches but what does the measurement actually mean well they are not all the same but they're referring to the ring sizes for round rings and measurements is the diameter of the inside of the Rings for slant or D rings it is the length of the straight edge then five inch binders come in and ruin everything they're measured from cover to cover and not by the ring sizes imagine it being more like how big of a stack pages you can fit in your binder and not a measurement of the thickness of the binder itself if you are curious here are some approximate cover widths for the corresponding ring sizes you can see that a five-eighths inch ring binder is actually slightly over an inch thick and a two inch binder can be almost three inches thick
