Tolerance — Why Things Are Built That Way.

Every object around you has a shape someone had to decide on. Almost always,
that decision is written down.

Tolerance takes one ordinary thing — a shipping pallet, a bank card, a crib rail,
a sheet of A4 paper — and finds the document that dictates its dimensions: an ISO
standard, an ASTM test method, a federal safety rule, a century-old patent. We
open the document on screen, read the number out loud, and trace it back to the
accident, the trade-off or the argument that produced it.

No opinions. No speculation. Just the specification, and what it costs when
someone ignores it.
