HTML Entity for Geometric Proportional (∺)
What You'll Learn
How to display the Geometric Proportional symbol (∺) in HTML using hexadecimal, decimal, named entity, and CSS escape methods. This character is U+223A (GEOMETRIC PROPORTION) in the Mathematical Operators block (U+2200–U+22FF).
Render it with ∺, ∺, ∺, or CSS escape \223A. Do not confuse ∺ with proportional to (∝, U+221D), which is a different operator.

🧠 How It Works
Hexadecimal Code
∺ uses the Unicode hexadecimal value 223A to display the Geometric Proportional symbol. The x prefix indicates hexadecimal format.
Decimal HTML Code
∺ uses the decimal Unicode value 8762 to display the same character.
Named Entity
∺ is the semantic named entity for ∺—the easiest to read in source HTML and part of the HTML5 character set.
CSS Entity
\223A is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.
Same visual result
All four methods produce the glyph: ∺. Unicode U+223A is in Mathematical Operators (U+2200–U+22FF). Next: Geometrically Equal To (≑).
Use Cases
The Geometric Proportional symbol (∺) is commonly used in:
Notation involving geometric proportion, ratios, or similar relations.
Textbooks, proofs, and content that expresses geometric proportionality.
Papers, specifications, and documentation using mathematical operators.
Online courses, tutorials, and resources for math or geometry.
HTML entity lists, Unicode charts, and math symbol documentation.
Web pages displaying mathematical expressions with proper typography.
💡 Best Practices
Do
- Use
∺for readable source markup - Pick one style (hex / decimal / named) per project
- Use math fonts (e.g. Cambria Math) for reliable glyph rendering
- Consider MathML for complex equations and accessibility
- Serve pages with UTF-8 (
<meta charset="utf-8">)
Don’t
- Confuse ∺ (geometric proportion) with ∝ (proportional to)
- Mix entity styles randomly in one file
- Put CSS escape
\223Ain HTML text nodes - Assume every font renders ∺ correctly
- Rely on the symbol alone without context for screen readers
