How to Read Numbers in English: Rules, Names, and Examples

Learning how to read numbers in English is an essential skill for every English learner. Whether you are talking about your age, telling the time, shopping, reading prices, or discussing large quantities, knowing how to say numbers correctly makes communication much easier.

But how do we read numbers such as 17, 45, 125, 3,450, or even 10,000,000 in English?

Don’t worry! In this guide, you will learn how to read numbers in English, from zero to ten million, with simple rules and plenty of examples.

Let’s get started!

1. How to Read Numbers from 0 to 12

Numbers from zero to twelve have special names that you need to memorize.

Examples:

• I have two brothers.
• She is eleven years old.
• There are twelve students in the classroom.

2. How to Read Numbers from 13 to 19

Numbers from thirteen to nineteen are called teen numbers because most of them end in “-teen”.

Here are their names:

Examples:

• My sister is fifteen years old.
• There are sixteen books on the table.
• He scored nineteen points.

💡 Remember: Teen numbers (13–19) can sometimes be confused with tens (30–90). Pay attention to the pronunciation!

3. How to Read Tens (20–90)

The tens are numbers that end in zero. Most of their names end in “-ty”.

⚠️ Watch out for these spelling mistakes!

• 40 is forty, NOT fourty.
• 50 is fifty, NOT fivety.
• 80 is eighty, NOT eightty.

4. How to Read Numbers from 21 to 99

To read numbers between 21 and 99, combine the tens with the units.

In written English, use a hyphen (-) between them.

Examples:

• My father is forty-five years old.
• There are thirty-two students in the school.
• The book costs sixty-eight dollars.

5. How to Read Hundreds (100–999)

To read hundreds, say the number of hundreds followed by the word hundred.

For example:

• 100 = One hundred
• 200 = Two hundred
• 300 = Three hundred
• 400 = Four hundred
• 500 = Five hundred
• 600 = Six hundred
• 700 = Seven hundred
• 800 = Eight hundred
• 900 = Nine hundred

When a number has tens or units after the hundreds, add the remaining part.

In British English, we commonly use and before the final part.

Examples:

• The school has one hundred and twenty students.
• She bought three hundred and forty-seven books.
• The journey is four hundred and fifty kilometres long.

6. How to Read Thousands (1,000–999,999)

When a number reaches 1,000, we use the word thousand.

Here are some examples:

Let’s look at some more complex numbers:

💡 Helpful tip: Read the thousands first, then read the remaining hundreds, tens, and units.

For example:

3,482

• 3,000 = Three thousand
• 400 = Four hundred
• 82 = Eighty-two

Together: Three thousand four hundred and eighty-two.

7. How to Read Millions (1,000,000 and Above)

For very large numbers, we use the word million.

Here are some examples:

Let’s practise reading some larger numbers:

Example:

Let’s read 4,256,789:

• 4 = Four million
• 256 = Two hundred and fifty-six thousand
• 789 = Seven hundred and eighty-nine

Together:

Four million two hundred and fifty-six thousand seven hundred and eighty-nine.

8. Important Rules to Remember When Reading Numbers

Here are some useful rules to help you read and write numbers correctly.

Rule 1: Learn the basic number names.

Memorize numbers from zero to nineteen and the tens from twenty to ninety.

Rule 2: Pay attention to “-teen” and “-ty”.

These endings help distinguish numbers such as:

• 13 = Thirteen
• 30 = Thirty
• 15 = Fifteen
• 50 = Fifty
• 17 = Seventeen
• 70 = Seventy

Rule 3: Use hyphens between tens and units.

When writing compound numbers between 21 and 99, use a hyphen.

Examples:

• 22 = Twenty-two
• 45 = Forty-five
• 91 = Ninety-one

Rule 4: Use hundred, thousand, and million.

These words help us read larger numbers.

Examples:

• 300 = Three hundred
• 4,000 = Four thousand
• 2,000,000 = Two million

Rule 5: Remember the use of “and”.

In British English, we commonly use “and” before the final part of a number after hundreds.

Examples:

• 125 = One hundred and twenty-five.
• 1,250 = One thousand two hundred and fifty.
• 1,005 = One thousand and five.
