Irish Script · 4th–10th Century · Standing Stones

Ogham Calculator

Type any text below to see it in Ogham — the script carved into standing stones across Ireland and parts of Britain, built from strokes set against a central stemline. This uses the real Unicode Ogham characters and the 20 core letters, grouped into four aicmí (families) of five.

Ogham Output

On letter coverage — Ogham was built for Old Irish, not modern English, so it has no native letters for J, K, P, V, W, X or Y. This calculator substitutes the closest core letter for common cases (K/C, V/F, W/U, Y/J→I) and leaves P and X unconverted. Digraph NG is matched before single N.
