How flags are specified

Ratio before pixels

A 2:3 flag is a relationship, not a fixed size. Every construction begins with a hoist-to-fly ratio.

H:F

Authority before approximation

Records distinguish legal construction sheets from common digital reproductions and inferred values.

DOC

Color with context

Official systems, print references, and screen equivalents are recorded separately when sources permit.

LAB

1:1

Method / FR–M01

Exact where possible.
Explicit where not.

Flag Record treats every flag as both a cultural object and an engineered artifact. A record states its sources, separates legal specifications from practical reproductions, and marks uncertain data plainly.

FLAG RECORD / EST. 2026

A practical public reference for the world’s flags.

Built for careful lookup, comparison, and construction—not decoration alone. This early release establishes the system; the registry will deepen record by record.
