saying large numbers in englishWe use different words to describe numbers depending on how many digits (numbers) they contain. We can also refer to the number of digits for simple generalisations. For example, 10,000 is five digits, so we refer to it as in the tens of thousands, but we may also call it a five figure number.

These are some of the ways we can describe numbers. Individual numbers will be called by their name, for instance 4 is four, 13,425 is thirteen thousand four hundred and 25. But they can also be grouped or generalised in a variety of ways. For instance 4 is also a single figure (or digit) number, and 13,425 is in the tens of thousands. The following table shows how we can describe some groups of numbers as they increase in size:











ten thousand


hundred thousand







In the past, there was a distinction between the American billion (1,000,000,000) and the British or European billion (1,000,000,000,000 – now the trillion), but in modern use the vast majority of the English speaking world has adopted the American version.

Saying a large number

We say large numbers by listing the numbers in order of size, biggest first. When reading a single number, all the number labels should be singular, for example 10,400 is ten thousand four hundred and not ten thousands four hundreds.

We describe three digit numbers in hundreds, then tens. Generally, in British English we usually connect large numbers with double or single digit figures with and, but in American English and is not used. Note that hundreds, thousands and millions are not connected to each other with and, though.

For example:

  • 345 is three hundred and forty-five (three hundred forty five in American).
  • 59,321 is fifty nine thousand, three hundred and twenty one. (not fifty nine thousand and three hundred…)

You can then describe large numbers with a series of different figures, grouping numbers in hundreds and tens, starting with the biggest number. So we describe hundreds/tens of millions, then thousands, then hundreds:

  • 1,345,612 = one million, three hundred and forty five thousand, six hundred and twelve
  • 153,200 = one hundred and fifty three thousand, two hundred

When we want to say where a number generally lies, in the above groups, we can say it is in the… For example, 14 is in the teens, 325 is in the hundreds. For tens and hundreds of larger numbers (thousands, millions), we say in the tens (or hundreds) of… So: hundreds of thousands and tens of millions.

Hundreds and thousands

Often it is easier to describe four figure numbers in hundreds instead of thousands. This is perfectly acceptable. For example, 1500 might be described as fifteen hundred, instead of one thousand five hundred (or one and a half thousand), because it is simpler to say.


Numbers as adjectives

All of these numbers can be referred to by the number of figures they contain, with plurals, for instance a number is in single figures (3), double figures (20) or quadruple figures (1,000). However, when we use the figure size of the number to describe a noun (such as a salary, price or to refer to a number itself) we simply use number + figure + noun. For example, a six-figure salary, a four-figure discount.

Alternative names for number groups

There are many informal alternative names for groups of numbers that can be used to simplify names. Beware you may not always be understood using these.
