What the Greek Letters Catalog does

This tab lists all 80 Greek signs on one page: classical letters, archaic numerals, scientific variants, accented vowels, polytonic marks, digraphs, numeral signs and math operators. Every card is a full 800×800 SVG with the Unicode code, Milesian isopsephy value, ISO 843 transliteration and IPA pronunciation. Use the category buttons and the search box to find a sign by its symbol, name, number or U+ code.

Click any card to open its details, hear the Greek pronunciation, copy the character, download the SVG or print a single-sign poster. The print button turns the whole catalog into an A4 wall chart, and each sign can also open a calligraphy tracing worksheet with outline or solid letters in three grid sizes.
