Meaning & usage

Measurements in feet and inches are written with primes: height 5′ 11″ is five feet eleven inches, and a 55″ TV is measured diagonally in inches. The double prime ″ is a real Unicode character, not two apostrophes typed together — using it keeps measurements aligned and unambiguous, and screen readers pronounce it correctly. The same marks measure arcminutes and arcseconds in astronomy and coordinates, which is why the degree page's ° pairs with ′ and ″ there too.

Frequently asked questions

How do I type the inch symbol?

There is no standard key for ″. Copy it from this page, or in Word type 2033 then Alt+X. Typing two apostrophes works visually in a pinch but is not the real character.

What is the difference between ″ and a quotation mark?

The double prime ″ is a measurement unit mark, slanted like a prime. The quotation mark " ends speech. In careful typesetting they are different characters.

Why does ″ sometimes show as a box or question mark?

The box (called tofu) means the device or font viewing it has no drawing for U+2033 (Double Prime). The character itself is fine — try a different font or a newer device, or use one of the variants on this page.

Is the Inch Symbol (Double Prime) free to use?

Yes. ″ is a standard Unicode text character published in the Unicode Character Database. You may use it in personal and commercial documents, designs and products without permission or payment.
