How to Write Greek Letters in LaTeX
Greek letters are essential in mathematics and science. LaTeX makes them easy to type in math mode.
Lowercase Greek Letters
Type the letter name preceded by a backslash:
$\alpha \beta \gamma \delta \epsilon \zeta$
$\eta \theta \iota \kappa \lambda \mu$
$\nu \xi \pi \rho \sigma \tau$
$\upsilon \phi \chi \psi \omega$Uppercase Greek Letters
Capitalize the first letter of the command:
$\Gamma \Delta \Theta \Lambda \Xi \Pi$
$\Sigma \Upsilon \Phi \Psi \Omega$Variant Forms
Some letters have alternative forms:
$\varepsilon$ vs $\epsilon$
$\vartheta$ vs $\theta$
$\varpi$ vs $\pi$
$\varphi$ vs $\phi$💡 Tips
- •Greek letters only work in math mode ($...$)
- •For Greek text (not math), use the textgreek package
- •\varepsilon (ε) is often preferred over \epsilon (ϵ) in physics
