About FlagLore

A flag looks simple until you actually have to make one, describe one precisely, or read one being waved across a harbor. What ratio should the fly be relative to the hoist? What color, exactly, is that red once it has to survive a print run or an embroidery machine? What size flag actually suits a given pole without looking lost or overwhelming the hardware? How does a signaller spell a word with two hand flags? What does a particular heraldic hatching pattern stand for? None of these questions are hard once you know the convention, but the conventions themselves are scattered across manufacturer charts, historical treatises, and signalling manuals.

FlagLore gathers that convention into one place, built around a set of small, single-purpose calculators. The Flag Proportion & Ratio Calculatorresolves a flag’s fly from its hoist (or the reverse) at any ratio, plus the area. The Flag Color-Spec Reference converts a hex color to RGB and CMYK for a print or embroidery spec. The Flag Size for Pole Height Calculator applies the standard quarter-to-third-of-pole-height rule to recommend a flag size. The Semaphore Flag Translator spells out any text in the standard hand-flag signalling alphabet. The Flag Identifier Quiz tests how well you can match a plain design description to the flag it belongs to. And the Heraldry Tincture Reference looks up the seven core heraldic tinctures and their historic Petra Sancta hatching pattern.

Beyond the calculators, the blog and learn section cover flag anatomy, proportion, color, semaphore, and heraldry in plain language, and the World Flags Museum is a browsable, photograph-led collection of flags from around the world, with every image and caption drawn from Wikipedia and Wikimedia Commons.

A few things worth stating plainly. FlagLore is an independent site, not affiliated with any government, flag manufacturer, or heraldic authority. It is supported by advertising, which is how the tools stay free with no account required. Every figure a tool produces — a dimension, a color conversion, a size recommendation, a semaphore position, a hatching pattern — is a general, educational calculation, not an official specification. Our coverage is strictly about design and history: proportions, colors, symbols, and signalling conventions, never commentary on any nation, government, or political dispute. If a tool result looks off, or you think a calculator is missing that would help, the contact page is the place to say so.
