one foot, two feet

'Feets' is not standard English. The correct plural of 'foot' is 'feet'. Use 'foot' for one, 'feet' for more than one, and the singular with a hyphen when the measurement modifies a noun (a six-foot ladder).

Quick answer

Use 'foot' for singular, 'feet' for plural. For measurements before a noun, use the singular + hyphen (a 5-foot pole).

One foot → singular.
Two feet → plural.
Adjective before noun: a five-foot table (not five-feet table).

Core explanation: irregular plural

Foot → feet is an irregular plural formed by a vowel change, not by adding -s. Think of similar pairs: tooth → teeth, goose → geese.

Rule of thumb: singular = foot, plural = feet.
If a number and unit form a compound adjective before a noun, use singular + hyphen (three-foot step).

Grammar: count nouns and verb agreement

Match the verb to the noun: use singular verbs with 'foot', plural verbs with 'feet'. When changing a sentence, re-check verb agreement and possessives.

My foot is sore. (singular verb)
My feet are sore. (plural verb)
Adjective before noun = singular (a 7-foot fence). After noun = plural (the fence is 7 feet tall).

Hyphenation: measurements used as adjectives

When a measurement directly modifies a noun, hyphenate and use the singular form of the unit: a six-foot ladder, a 10-foot ceiling.

Before noun (compound adjective): 5-foot pole / five-foot pole.
After noun (measurement phrase): the pole is 5 feet long.

Spacing and symbols: writing 'feet' with numbers

Either spell the unit out (five feet) or use an abbreviation with a space (5 ft). Avoid squashed forms like '5ft' in formal writing.

Preferred: '5 ft' or 'five feet'.
Compound adjective: 'a 5-foot pole' or 'a five-foot pole'.
