What Is Gematria?

Gematria (pronounced geh-MAY-tree-ah) is the ancient practice of assigning numerical values to letters, words, and phrases — and using those values to reveal deeper meaning, identify connections between concepts, and decode hidden patterns in text. The practice originates in ancient Hebrew and Greek traditions, where it was used extensively in biblical, Talmudic, and Kabbalistic study.

The word itself comes from the Greek geometria (geometry) — the same root that gives us geometry in mathematics. In ancient Greek culture, letters and numbers were the same symbols, making the numerical interpretation of words entirely natural rather than esoteric.

The Four Gematria Systems

English (Simple) Gematria — A=1 to Z=26

Simple English gematria assigns sequential values to the alphabet: A=1, B=2, C=3 through Z=26. It is the most widely used system in contemporary gematria research, particularly in English-speaking contexts. Its simplicity makes it accessible and its results — totals that do not need reduction — are easy to compare across words and phrases.

Simple English gematria is also the direct ancestor of the Pythagorean numerology alphabet used in modern Western name numerology. When you calculate your Expression Number in standard numerology, you are performing a form of Simple gematria on your birth name.

Hebrew (Jewish) Gematria — Ancient Biblical System

Hebrew gematria is the oldest documented system, used in Jewish scripture and tradition for over 2,500 years. The Hebrew alphabet assigns values that extend into the tens and hundreds: Aleph=1, Bet=2 through Yod=10, Kaf=20, through Tav=400. When applied to English letters, each English letter takes the value of its positional Hebrew equivalent.

This is the system most associated with biblical gematria — the analysis of words in the Torah and Talmud whose numerical values reveal connections between concepts, names, and prophecies. The most famous example is 18 (Chai — meaning life) and 36 (double Chai), which remain significant in Jewish culture today.

Greek Gematria — Isopsephy

Greek gematria, known as isopsephy, follows the Greek numeral system where letters are assigned values extending into the thousands. Alpha=1 through the Greek alphabet's 24 letters, with values of 1–800. Greek gematria was used extensively in early Christian tradition, in classical Greek philosophy, and in the writing of the New Testament, where numerical patterns were considered to carry theological significance.

What the Results Mean — Single Digit Reduction

In numerological interpretation, gematria values are typically reduced to a single digit (or Master Number) by adding the digits together repeatedly. The resulting root number carries the core interpretive meaning. This bridge between gematria and numerology is the foundation of name numerology: the Expression Number, Soul Urge, and Personality Number are all derived from gematria values of your name letters, reduced to their numerological root.

Gematria and Numerology — The Connection

Many people discover gematria through numerology, or numerology through gematria — because they are, at root, the same practice applied in different cultural contexts. Modern Western numerology uses the Pythagorean letter-value system (A=1 through Z=8, cycling 1–9) which is a modified version of Simple English gematria. The Chaldean system used in Indian name numerology uses a different mapping (based on vibrational frequency rather than sequential order) but is equally a gematria system.

The key differences are in application: gematria as practiced in Kabbalistic and biblical traditions tends to focus on word-to-word connections and textual patterns. Numerology focuses on personal profile numbers derived from birth name and birth date. But the underlying mechanism — letter to number, number to meaning — is identical.

Gematria in the Bible

Biblical gematria appears throughout both the Old and New Testaments. In the Hebrew Bible, the most cited examples include the word Chai (life) equalling 18, which remains significant in Jewish practice today — many Jewish charitable gifts are given in multiples of 18. The name David in Hebrew gematria equals 14, which Matthew's Gospel specifically highlights in the genealogy of Jesus (three groups of fourteen generations).

In the New Testament, the most famous example is Revelation 13:18, where 666 is called the Number of the Beast. Most scholars now agree this referred to Nero Caesar, whose name in Hebrew gematria totals 666 — a coded message intelligible to Jewish Christians of the first century but opaque to Roman authorities.

How to Use This Calculator

Enter any word, name, or short phrase in the field above. The calculator returns values in all four systems simultaneously, with a letter-by-letter breakdown for each. Use the system tabs below the main results to see exactly how each letter contributes to the total in each tradition.

For name numerology specifically: enter your full birth name as it appears on your birth certificate to get your Expression Number (the total reduced to a single digit in the English system). Enter vowels only for your Soul Urge Number. Enter consonants only for your Personality Number.
