Have you ever typed “heighth” and wondered if it should be “height” instead? You are not alone. The phrase “heighth or height” is a common spelling question because English has many words that end in -th, such as width, depth, and length. It can seem logical to write heighth in the same way.
The good news is simple: height is the standard spelling in modern English.
The word height means how tall something is or the distance from the bottom to the top. For example, you can talk about a person’s height, the height of a building, or the height of a mountain.
But the story is more interesting than the spelling suggests. Heighth has appeared in English for centuries and still exists as a historical or nonstandard variant. This explains why some people have seen or heard it.
This guide explains heighth or height, including the history of both forms, British and American usage, common mistakes, examples, and practical advice for professional writing.

The Origin of Heighth or Height
The history of height helps explain why the spelling looks unusual.
The modern word comes from Old English forms such as hīehþu, hēahþu, and hēhþo. These forms were related to the word high and referred to a high point or the quality of being high.
Over time, the word changed through Middle English. Forms such as heighte and other spellings appeared before the modern spelling height became established.
The meaning also developed. By the late 13th century, height could mean the distance from the bottom to the top. By the late 14th century, it could also describe the highest degree of something, as in “the height of success.”
Why does “heighth” exist?
Heighth is not simply a modern typo. Historical records show that variants resembling heighth were used in English.
The spelling also seems natural because English has words such as:
- length
- width
- depth
- breadth
These words end in -th, so speakers may naturally form heighth by analogy.
Etymological sources describe heighth as an obsolete or colloquial variant of height.
This is why you may occasionally see heighth in older texts, regional speech, or informal writing.
British English vs American English Spelling
There is no major British-versus-American spelling difference here.
Both British English and American English use height as the standard spelling.
| Feature | British English | American English |
| Standard spelling | height | height |
| Nonstandard variant | heighth | heighth |
| Formal writing | height | height |
| Common noun | height | height |
| Example | The height is 2 metres. | The height is 2 meters. |
Notice that metres/meters changes between British and American English, but height does not.
For example:
- 🇬🇧 British: The height of the building is 50 metres.
- 🇺🇸 American: The height of the building is 50 meters.
The spelling height stays the same.

✅ What is the height of the building?
This is a common typing error caused by switching the letters.
3. Heightt
