Quick answer: A pair is two things that belong together or are naturally matched: a pair of shoes / gloves / scissors. A couple informally means two or a few: a couple of minutes / a couple of friends. Couple can sometimes mean “approximately two or three”, while pair always means exactly two matching items. For a fuller definition, see the Cambridge Dictionary entry for ‘couple’.

Using Pair
Use pair for two items that belong together as a unit, especially things that come in twos by nature. Many items that look plural take pair: trousers, scissors, glasses, gloves, socks, shoes.
I need a new pair of shoes.
She bought a pair of earrings.
Hand me those scissors — the pair on the table.
A pair of horses pulled the carriage.
Pairs of Plural-Only Objects
Many objects in English exist only in plural form but are still one item. We use a pair of to treat them as singular: a pair of trousers / jeans / pyjamas / tongs / pliers.
Using Couple
Couple is more informal. It means two people in a romantic relationship, or approximately two (sometimes three) of something. It is always followed by of when used before a noun.
I’ll be ready in a couple of minutes.
A young couple sat opposite us on the train.
Can I borrow a couple of eggs?
She’s been away for a couple of weeks.

Frequently Asked Questions
What is the difference between couple and pair?
A pair is exactly two things that belong or go together naturally (shoes, gloves, scissors). A couple informally means two or approximately two to three things, and is used for people in a relationship or small quantities.
Do I need “of” after couple?
Yes. When couple is used before a noun, you need “of”: a couple of hours, a couple of friends. Without “of” it sounds wrong: a couple hours is informal American English but non-standard in British English.
Is “a pair of trousers” one item or two?
“A pair of trousers” is one garment. Trousers (like scissors, glasses, pyjamas) is a plural-form noun that refers to a single object with two parts, so we use a pair of to treat it as singular.
Can “couple” mean more than two?
Informally, a couple of can mean two or three: “I’ll be there in a couple of minutes” does not always mean exactly two minutes. In formal contexts, use two if precision matters.
Can pair be used for people?
Yes, in the sense of two people doing something together: “The students worked in pairs.” But for a romantic couple, use couple: “They make a lovely couple.”
What is the plural of “pair”?
The plural is pairs: “three pairs of shoes.” Note that you can also say “six pairs of socks” or informally “six pairs” (when the noun is understood).
What is “a happy couple” vs “a happy pair”?
“A happy couple” refers to two people in a romantic relationship. “A happy pair” sounds more literary or humorous, sometimes applied to two people who get along well but are not necessarily romantic partners.
Is “a couple hours” correct?
In standard British English, the correct form is a couple of hours. Dropping “of” (a couple hours) is common in informal American English but is not standard in British English.
Does “pair” have a verb form?
Yes. To pair means to match two things together: “She paired the red wine with lamb.” / “The students were paired up for the exercise.”
What about “a couple” as a noun for a romantic relationship?
In British English, a couple (noun) refers to two people in a romantic or sexual relationship: “They became a couple last year.” It can take singular or plural verb: “The couple is/are planning a wedding.”
