Case 6 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained

Correction to a common shortcut: don't measure lug width on an existing strap. Leather and rubber straps compress or swell, and some are made slightly undersized on purpose. Always measure between the lugs themselves, with the strap removed if possible.
