Meaning & usage

Heights, room sizes and depths in imperial measurements are written with the prime: a 6′ fence, a pilot at 30,000′ (feet of altitude), a board 8′ long. The prime ′ is its own Unicode character — not an apostrophe — which matters in drawings and spec sheets where ' would mean minutes of arc in a different column. Its partner ″ covers inches, and the two together write any imperial length.

Examples in use

A 6′ 2″ basketball player
Ceiling height 9′
2 × 4 timber, 8′ long

Frequently asked questions

How do I type the feet symbol?

There is no standard key for ′. Copy it from this page, or in Word type 2032 then Alt+X.

Feet use ′ and inches use ″ — how do I remember?

Feet are the bigger unit and get the first (single) mark; inches follow with the double mark — as in 5′ 11″, read 'five foot eleven'.

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+2032 (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 Feet Symbol (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.
