Open-end head width ≈

1.6× to 2.0× the jaw width

So if:

Jaw width = 8 mm

Expect total head width ≈ 13–16 mm

This varies by:

Manufacturer

Whether it’s slimline or heavy-duty

Angle of the open end (15° offsets add bulk)

What you can reliably infer

If the slot is barely wider than the fastener → open end probably won’t fit

If the slot width ≥ ~2× fastener size → good odds

Box ends almost always need more clearance than open ends

If you want to formalize this (which I know you do 😄):

Measure one wrench head

Create a personal ratio table

Treat it like your screwdriver blade-width taxonomy

TL;DR mental stack

Points ≠ size (points = geometry, size = diameter)

Box end = strength, open end = access

Righty-tighty / lefty-loosey, not toward/away

Open-end head ≈ ~1.6–2× jaw width (rule-of-thumb)
