Greek Letters in HTML: Complete Entity Reference

Display Greek letters on web pages using HTML entity codes. This guide covers named entities, decimal codes, and hexadecimal codes for all Greek alphabet characters.

How to Use HTML Entities

There are three ways to insert Greek letters in HTML:

1. Named Entities (Easiest)

Format: &entityname;
Example: α displays as α
Pro: Easy to remember and read
Con: Not all letters have named entities

2. Decimal (Numeric) Codes

Format: &#number;
Example: α displays as α
Pro: Works for all Unicode characters
Universal: Based on Unicode code points

3. Hexadecimal Codes

Format: &#xHEX;
Example: α displays as α
Pro: Matches Unicode hex notation
Use: When working with Unicode tables

Tips for Using Greek HTML Entities

Best Practices

UTF-8 Encoding: Always use <meta charset="utf-8"> in your HTML head
Named vs Numeric: Use named entities for common letters (easier to read), numeric for rare ones
Semicolons: Always include the semicolon at the end: α not &alpha
Case Sensitive: Α (uppercase) ≠ α (lowercase)

Common Mistakes to Avoid

Missing Semicolon: &alpha won't work (must be α)
Wrong Case: &ALPHA; doesn't exist (use Α)
Space Before Semicolon: &alpha ; won't work
Forgetting Ampersand: alpha; displays literally, not as α

Browser Compatibility

Named Entities: Supported in all modern browsers (IE6+, Chrome, Firefox, Safari)
Numeric Codes: Universal support in all browsers
UTF-8 Direct: You can also paste Greek letters directly if using UTF-8 encoding
