for spring clamps, the [75% RULE] is actually pretty decent.
so i’d use:
-[4-1/8″ SPRING CLAMP]-
[MAX OPEN JAW: 2.54 CM]
[RECOMMENDED WORKING THICKNESS: 1.9 CM]
[CONSERVATIVE WORKING THICKNESS: 1.5 CM]
[JAW CONTACT DEPTH / FACE: about 2.2 CM]
.
-[2″ SPRING CLAMP]-
[MAX OPEN JAW: 1.905 CM]
[RECOMMENDED WORKING THICKNESS: 1.43 CM]
[CONSERVATIVE WORKING THICKNESS: 1.1–1.2 CM]
[JAW CONTACT DEPTH / FACE: about 1.0 CM]
the logic:
[100% OF MAX OPEN JAW] = possible, but not ideal as your default
[75% OF MAX] = good everyday working estimate
[60% OF MAX] = safer for slippery / rounded / delicate / padded material
so your clean rule could be:
[SPRING CLAMP DEFAULT RULE]
[RECOMMENDED WORKING THICKNESS = about 75% of max open jaw]
and then a second note:
[FOR SMOOTH / COMPRESSIBLE / BULKY MATERIAL, DROP TO ABOUT 60%]
for WP, i’d probably phrase it like this:
[4-1/8″ SPRING CLAMP / 10.5 CM]
[max open jaw: 2.54 cm]
[recommended working thickness: 1.9 cm]
[conservative working thickness: 1.5 cm]
[2″ SPRING CLAMP / 5.08 CM]
[max open jaw: 1.905 cm]
[recommended working thickness: 1.43 cm]
[conservative working thickness: 1.1–1.2 cm]
one distinction worth keeping:
[binder clips] = easier to talk about in terms of [holding capacity]
[spring clamps] = better described by [max jaw opening] + [recommended working thickness]
because with spring clamps, the actual hold depends more on surface texture, pad shape, and what part of the jaw is contacting the object.
If you want, I can also turn this into the same exact bracketed WP format as the binder clip list so the 2 systems visually match.
