I took some time to measure the spacing of various wrench organizers, as I’m constantly trying to balance the competing goals of easy, visible access and wasted space. Since I have tried them all, I figure this info might help others choose.
Here is the spacing between wrenches of most popular organizers, measured in inches:
Some comparison photos:

The 3D printed eBay versions didn’t have a brand unfortunately

The results of my research: most sets in Ernst 40-tool wrench rail sets, which are two 20-tool rails mirrored. Large wrenches in Toolbox Widgets, thin and flare nut wrench sets in OEM Tools or eBay rails. This setup fits 264 wrenches (one is missing from the photo, if anyone chooses to count) up to 32mm or 1-3/8” wrenches in a 3” tall Snap-on KRL1032 drawer.

Ernst Wrench Pro organizers are the perfect spacing for average-size screwdrivers when staggered:
