How to Type Greek Letters on Any Device

How to type Greek letters depends on your device and your app, but every system has at least one built-in method. This guide covers Windows, Mac, iPhone, Android, Word, Google Docs, LaTeX and HTML. Each section gives the quickest method first, then links to a detailed guide.

If you only need one letter right now, copying is faster. So grab it from our Greek letters copy and paste page, then come back when you want a permanent setup.

How to Type Greek Letters on Windows

On Windows, the most reliable way to type Greek letters is to add the Greek keyboard layout. Then you switch layouts with one shortcut and type Greek directly.

Add the Greek keyboard layout

1. Open Settings, then Time & language, then Language & region.
2. Click Add a language, search for Greek, and install it.
3. Next, press the Windows logo key + Spacebar to switch between English and Greek.
4. Type with the Greek layout active, for example A for α and S for σ.

Microsoft documents these steps in its keyboard layout help page. Also, the language icon in the taskbar shows which layout is active.

Use the emoji and symbol panel

Windows 11 has a symbol picker that needs no setup. Press the Windows logo key + period (.), open the Symbols section, and browse the sets for Greek letters. Click a letter to insert it.

Use Alt codes for a few letters

Alt codes work for 14 Greek characters only. For instance, hold Alt and type 224 on the numeric keypad to get α, or 228 to get Σ. Our Greek letters alt codes chart lists all of them, plus the catches.

How to Type Greek Letters on a Mac

On a Mac, add the Greek input source and type Greek directly from your keyboard. Alternatively, use the Character Viewer when you only need a symbol now and then.

1. Choose Apple menu, then System Settings, then Keyboard.
2. Under Text Input, click Edit, then click the Add (+) button.
3. Search for Greek, select it, and click Add.
4. Then press Control+Space to switch to the last input source you used.

Apple covers the details in its guide to writing in another language. For the Character Viewer, press Fn/Globe+E and search for a letter name such as “theta”.

Be careful with Option shortcuts on the US layout. Option+P gives a real π, but Option+J gives ∆, the increment sign, rather than Greek Δ. Our guide on how to type Greek letters on Mac lists every one of these traps.

Not sure where a letter sits? Choose Show Keyboard Viewer from the Input menu in the menu bar. The viewer shows the Greek layout on screen, and it updates when you hold Shift or Option.

You can also let Caps Lock do the switching. In the Text Input settings, turn on the option to use Caps Lock to switch between Latin and non-Latin sources. Then one tap moves you between English and Greek.

Greek Keyboard Layout Map

The standard Greek layout maps most letters to a Latin key with a similar sound. So once you learn a few exceptions, you can touch-type Greek on Windows or Mac. Hold Shift for the capital form, as you would in English.

Key	Lower	Upper	Letter
A	α	Α	Alpha
B	β	Β	Beta
G	γ	Γ	Gamma
D	δ	Δ	Delta
E	ε	Ε	Epsilon
Z	ζ	Ζ	Zeta
H	η	Η	Eta
U	θ	Θ	Theta
I	ι	Ι	Iota
K	κ	Κ	Kappa
L	λ	Λ	Lambda
M	μ	Μ	Mu
N	ν	Ν	Nu
J	ξ	Ξ	Xi
O	ο	Ο	Omicron
P	π	Π	Pi
R	ρ	Ρ	Rho
S	σ	Σ	Sigma
T	τ	Τ	Tau
Y	υ	Υ	Upsilon
F	φ	Φ	Phi
X	χ	Χ	Chi
C	ψ	Ψ	Psi
V	ω	Ω	Omega
W	ς	–	Final sigma

The exceptions are easy to remember. For example, θ sits on U, ξ sits on J, ψ sits on C and ω sits on V. In addition, W gives the final sigma ς, which Greek uses at the end of a word. Each letter has its own page, such as the theta symbol or the psi symbol.

How to Type Greek Letters on iPhone and Android

On a phone, add a Greek keyboard once, then switch to it with the globe or space bar. Both iPhone and Android include a Greek layout for free.

iPhone and iPad

1. Go to Settings, then General, then Keyboard, then Keyboards.
2. Tap Add New Keyboard and choose Greek.
3. In any app, touch and hold the globe key and slide to Greek.

Android with Gboard

1. Tap a text field, then tap the settings icon on the keyboard.
2. Open Languages, tap Add keyboard, and pick Greek.
3. After that, touch and hold the space bar to switch languages.

Google lists the same steps in the Gboard help center. On both systems, the Greek layout follows the map above.

Greek Letters in Word and Google Docs

Word gives you three methods: the symbol dialog, Alt+X codes and Math AutoCorrect. Google Docs offers a special characters tool and an equation editor.

• Word, Insert > Symbol: choose More Symbols, set the subset to Greek and Coptic, then double-click a letter.
• Word, Alt+X: type the hex code, such as 03B1, and press Alt+X to turn it into α.
• Word equations: press Alt+= and type \alpha followed by a space to get α.
• Google Docs: choose Insert > Special characters and search for “alpha”, or use Insert > Equation and type \alpha.

Each method has small quirks, such as fonts and spacing. So our full guide to Greek letters in Word and Google Docs shows each step in order.

Greek Letters in LaTeX

In LaTeX, you type a backslash and the letter name inside math mode. For example, $\alpha$ gives α and $\Omega$ gives Ω.

However, capitals that look like Latin letters have no command. You write a plain A for capital alpha and a plain B for capital beta. Also, \epsilon prints the lunate ϵ, while \varepsilon prints ε.

The complete LaTeX Greek letter command list includes every variant form. For context on how each letter is used, see Greek letters in math.

Greek Letters in HTML Code

In HTML, you type a Greek letter with a named entity or a numeric reference. For instance, α, α and α all display α.

Named entities are easiest to read, because Σ is clearer than a number. Still, if your page uses UTF-8, you can paste the character itself. Our Greek letters Unicode and HTML code chart covers all 24 letters.

Fixing Common Greek Typing Problems

Most Greek typing problems have one of four causes. Each one has a quick fix.

• Alt codes do nothing: turn on Num Lock and use the numeric keypad, not the number row. Many laptops lack a keypad, so use the Windows+period panel instead.
• An empty box appears: the font has no Greek glyph. Switch to a font with Greek coverage, such as Arial or Times New Roman.
• The wrong symbol appears: you may have typed a lookalike, such as the micro sign µ instead of μ. Check the code point in a symbol dialog.
• Accents are missing: on the Greek layout, the semicolon key adds the tonos accent. Press it first, then the vowel, to get ά or έ.

Lookalikes cause the most confusion, because they look right on screen. For example, Mac Option+Z gives the ohm sign Ω (U+2126), not Greek capital omega. Our omega symbol page and the ohm symbol guide explain which one to choose.

Similarly, the mu symbol and the micro sign look the same in most fonts. Unicode recommends Greek μ (U+03BC) for new text, so a Greek keyboard is the safest source.

Which Method Should You Use?

The best method depends on how often you type Greek. Here is a simple rule of thumb.

• Once in a while: copy from the copy and paste tiles.
• Several times a week: use the symbol panel, Character Viewer or Word’s Alt+X.
• Every day, or full words: add the Greek keyboard layout on each device.
• Math papers: use LaTeX, or Word’s equation editor for quick documents.

Fonts matter too. If a letter shows as an empty box, your font lacks Greek glyphs, so switch to one from our Greek letter font list. Then any method in this guide on how to type Greek letters will display cleanly.

Frequently Asked Questions

What is the fastest way to type Greek letters?

For occasional use, copy and paste is fastest. For regular use, add the Greek keyboard layout and switch with Windows+Space or Control+Space on a Mac.

How do I type the alpha symbol on a keyboard?

On Windows, hold Alt and type 224 on the numeric keypad. In Word, type 03B1 and press Alt+X. On a Mac, switch to the Greek input source and press A.

Which key gives omega on a Greek keyboard?

On the standard Greek layout, V gives ω and Shift+V gives Ω. Similarly, U gives θ and C gives ψ.

Can I type Greek letters without changing my keyboard?

Yes. Use the Windows emoji panel (Windows+period), the Mac Character Viewer (Fn/Globe+E), Word’s Alt+X codes or copy and paste.

How do I type Greek letters in Google Sheets?

Google Sheets has no special character menu. Copy the letter from Google Docs or from our copy and paste page, then paste it into a cell.
