Mathematical Double-struck Small R Symbol
𝕣 is the mathematical double-struck small letter r (U+1D563), used in formal notation.
U+1D563
The symbol 𝕣 is a double-struck lowercase r used in mathematical typesetting. It’s useful when you want a distinct font style that stands apart from regular italic r. This page helps you copy it reliably and use the correct code point.
Mathematical Double-struck Small R Symbol Meaning
𝕣 is the Unicode character “MATHEMATICAL DOUBLE-STRUCK SMALL R” (U+1D563). Double-struck letters are commonly used in mathematical documents to convey a particular typographic style distinct from standard italic or script forms. In practice, 𝕣 may appear in formal writing where authors want to emphasize a specific symbol with a consistent, recognizable look—often as part of a set, a constant, or a variable in a particular notation scheme. Since the exact meaning depends on the context (and on the author’s conventions), it’s best treated as a styled “r” intended to match the surrounding mathematical notation.
Common uses
- •Typing or copying styled mathematical variables in LaTeX-like text
- •Designing math-focused posters, slides, or documentation where double-struck glyphs are preferred
- •Labeling variables or parameters in technical writing to match a published notation style
- •Creating consistent UI text for math editors, formula builders, or iconographic math labels
- •Sharing equations or explanations on websites and social media with correct Unicode support

What Unicode character is 𝕣?
𝕣 is U+1D563, named “MATHEMATICAL DOUBLE-STRUCK SMALL R”.
How do I copy 𝕣 correctly from this page?
Copy the character directly (𝕣). If you need a code-based version, use the HTML entity, CSS escape, or JavaScript escape from the symbol’s page.
Will 𝕣 look the same on every device?
It should render as the intended double-struck glyph when the font supports U+1D563. If the font lacks support, it may fallback to a different style or appear as a missing character box.
Is 𝕣 always the same meaning in math?
Not necessarily. Double-struck letters are a typographic convention, so the exact meaning of “r” depends on the notation used in a specific document or problem.
