Double Prime Symbol Meaning
The double prime symbol (″) is Unicode character U+2033. It is commonly used to represent measurements in inches in contexts where a single quote (′) would represent feet or another unit, and the double prime is used for inch-style notation. In general writing and typesetting, it can also serve as a distinct “double quotation-like” mark where the typographic intent is specifically a prime/double-prime rather than standard quotation marks. Because it is visually close to other quotation characters, using ″ helps ensure consistent rendering in documents, designs, and software when you need the exact Unicode character.
Common uses
- •Write inch measurements like 5″ for product dimensions and specs
- •Use in typographic systems where primes/double-primes are preferred over standard quotes
- •Label coordinates or derived values in technical documents and diagrams
- •Display measurement-style notation in UI mockups and dashboards
- •Insert the exact character for consistency in templates, forms, or style sheets
