Case 56 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained · source wording exercise

I want to buy aftermarket straps but keep seeing 20/16, 22mm, 4mm thick and spring bar sizes. Which measurements do I actually need to take from my watch, and how do I measure them without the right tools?

Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Measure with a ruler marked in millimetres, ideally…” as the discussion anchor; no new event or result is supplied.

Exercise RWI-20616/56: address this question within its stated limits.
