Why every size in Urcrib says how sure it is
A plan that hides its doubt is a plan you cannot buy from. Ours shows it on every number.

Every length in Urcrib carries two things: the number, and how it was measured. From how it was measured comes how sure it is.
- Tape measure — ±30 mm
- Counted in tiles — ±5%
- Paced in steps — ±10%
- A typical size, nobody measured it — ±15%
- The size a piece is sold as — ±3%
Why it matters
When a wardrobe has 5 cm to spare against a wall you counted in tiles, the honest answer is not "it fits". It is "it probably fits — check that wall with a tape". Urcrib says exactly that, and only when it matters.
No number in the plan is ever a guess dressed as a measurement.
