LaTeX Greek Letters FAQ

How to write Greek letters in LaTeX?

Inside math mode, type a backslash and the letter's name: $\alpha$ gives α and $\Omega$ gives Ω. Lowercase names give small letters and capitalised names give capitals.

How to bold Greek letters in LaTeX?

Use \boldsymbol{\alpha} from amsmath or \bm{\alpha} from the bm package. \mathbf only bolds Latin letters and upright capitals, so it leaves lowercase Greek unchanged.

How to write capital Greek letters in LaTeX?

Capitalise the name: \Gamma, \Delta, \Theta, \Lambda, \Xi, \Pi, \Sigma, \Upsilon, \Phi, \Psi and \Omega. The other capitals look like Latin letters, so you type A, B, E and so on.

How to write Greek letters in text in LaTeX?

Wrap the command in math mode, as in $\alpha$, which works anywhere in a sentence. For whole words in Greek, load babel with the greek option, or use XeLaTeX with a font that has Greek.

How to write delta symbol in LaTeX?

Type \delta for δ and \Delta for Δ, inside math mode. The same pattern works for every letter: \sigma, \mu, \pi, \phi and the rest are all in the table above.

How to italicize Greek letters in LaTeX?

Lowercase Greek is already italic in math mode, while capitals are upright. For italic capitals, use \varGamma, \varDelta and the other var forms from amsmath.

How to put tilde over Greek letters in LaTeX?

Wrap the letter in an accent command: \tilde{\alpha}, \bar{\alpha}, \hat{\theta} or \vec{\mu}. For a bar over several symbols at once, use \overline.

How can I make the sigma symbol bigger in LaTeX?

For a summation, use \sum rather than \Sigma: it grows in displayed equations and puts the limits above and below. To enlarge a single letter, use \scalebox from graphicx.

How come my Greek isn't showing up LaTeX?

Usually the command sits outside math mode, so LaTeX stops with a "Missing $ inserted" error. Put it between dollar signs and check the spelling, since \Alpha and \omicron do not exist.

What are Greek letters in LaTeX?

They are the commands LaTeX uses to print the Greek alphabet in formulas, such as \alpha, \beta and \pi. Scientists use them for angles, constants and variables.

How do I write upright (non-italic) Greek letters in LaTeX?

Load the upgreek package and write \upalpha, \upmu and so on. Fonts such as newtxmath offer \alphaup instead, and siunitx users can write \micro for the micro sign in units.

Do I need a package for Greek letters in LaTeX?

Not for the basic set of LaTeX Greek letters. Only \varkappa and \digamma (amssymb), the bold and italic forms (amsmath or bm) and the upright ones (upgreek) need one, and each tile says which.

Is there a full list of LaTeX Greek letters?

This page is one: every one of the LaTeX Greek letters, with the 24 lowercase forms, the variant shapes and the capitals, each beside its command. Search by name or symbol and copy with a click.

What are the variant Greek letters in LaTeX?

Six letters have a second shape: \varepsilon, \vartheta, \varpi, \varrho, \varsigma and \varphi. \varkappa joins them with amssymb. Which one to use is a matter of house style.

Can I write calligraphic or script Greek letters?

Standard LaTeX has no calligraphic Greek, and \mathcal only covers Latin capitals. Some math fonts used through unicode-math do provide script or sans-serif Greek.

Can I use Greek letters in section titles or the bibliography?

Yes, in math mode as usual. With hyperref, wrap the letter in \texorpdfstring so PDF bookmarks show plain text such as alpha instead of a warning.

Do these commands work in Overleaf, Obsidian and Markdown?

Yes. Overleaf runs real LaTeX, and Obsidian, Jupyter and most Markdown editors render maths with MathJax or KaTeX, which understand the same commands.

What is the difference between \epsilon and \varepsilon?

\epsilon gives the lunate shape ϵ and \varepsilon the rounder ε that many people expect. The same goes for \phi (ϕ) and \varphi (φ).

Why is there no \Alpha command?

Capital alpha looks exactly like the Latin A, so LaTeX leaves it out; type A instead. The same applies to Beta, Epsilon, Zeta, Eta, Iota, Kappa, Mu, Nu, Omicron, Rho, Tau and Chi.

Can I type α directly instead of \alpha?

With XeLaTeX or LuaLaTeX and the unicode-math package, yes: α in math gives the same result as \alpha. pdfLaTeX needs extra setup, so the commands are the safer choice.

How do I copy a command from this page?

Click a tile and its command goes to your clipboard; a tick confirms it. Use the search box to filter by name, such as theta, or by the symbol itself.
