Key Takeaways

  • A carpet means £300 in modern British slang.
  • It originally meant £3, and the value scaled up over the years.
  • The prison link is key: "carpet" was slang for a three-month sentence.
  • It is niche slang, heard mainly in racing, market, and older London contexts.

Where Does 'Carpet' Come From?

The most cited origin is prison slang. A "carpet" was a three-month sentence, said to be the time it took to weave a carpet in prison workshops.

From "three" months, the word came to mean the number three in money: first £3, later £300 as amounts grew. The link is the number, not the floor covering.

How People Use 'Carpet'

It appears most in horse racing and betting talk, where odds and stakes use colourful slang.

For example, odds of 3 to 1 can be called "carpet". A stake or sum of £300 may also be described this way in those circles.

Outside racing and market settings, it is not widely known, so it needs explaining to most listeners.

A Carpet Versus Other Money Slang

A carpet is one of the more specialised terms. Everyday words like ton for £100 are far more common.

For nearby amounts, a monkey is £500 and a pony is £25. Our Cockney slang for money guide covers the wider family of terms.
