Heighth or Height: Which Spelling Is Correct?

Have you ever written a word so many times that it suddenly looks wrong? 

Heighth or height is one of those spelling questions that can make even confident English users stop and check. 

The two forms look almost the same, but only one is the standard spelling in modern English. 

If you are writing an email, school assignment, website, report, or product description, choosing the right form matters. 

People often search for “heighth or height” because they hear the word pronounced in different ways or because words such as length, width, 

and depth seem to suggest that “heighth” should also exist. This can create doubt about both spelling and pronunciation. 

The good news is that the answer is simple: height is the standard spelling. Heighth is a nonstandard or dialectal form that appears in some historical and regional usage. 

This guide explains the difference, explores the history of both forms, compares British and American English, and gives clear examples to help you use the word correctly.

Heighth or Height Quick Answer

Height is the standard and correct spelling in modern English.

Heighth is a nonstandard or dialectal variant of height. 

Major dictionaries describe it as nonstandard, obsolete, or dialectal rather than as the normal spelling for professional English.

Correct:

• What is the height of the building?
• The tree reached a height of 20 feet
• She is of average height
• The plane reached a great height

Nonstandard:

• What is the heighth of the building?
• The tree reached a heighth of 20 feet

The standard pronunciation of height is /haɪt/, which sounds like “hite.” The extra th sound found in some pronunciations of “heighth” is not part of the standard pronunciation.

The Origin of Heighth or Height

The word height has a very old history. It comes from Old English forms such as hēahþu, hēhþo, and hīehþu, which were related to the word high. 

Over time, the word changed through Middle English before developing into the modern form height.

The word originally referred to a high point, summit, or elevated position. 

By the late 13th century, height was also used for the distance from the bottom of something to its top. Later, it developed wider meanings, including a high level or peak of something.

The spelling history is not as simple as modern English makes it seem. Historical forms included heighthe, hegthe, highth, and heighth. 

The modern pronunciation ending in /t/ became established much later. Historical writers, including John Milton, used forms such as highth.

Why does heighth still appear? One reason is that English speakers may connect height with words such as length, width, and breadth, which end in -th. 

This pattern can make “heighth” seem logical. Historical and dialectal usage also helped keep the form alive in some varieties of English.

However, modern standard English settled on height.

British English vs American English Spelling

There is no standard British-American spelling difference between these two forms. Both British and American English use height as the standard spelling.

English variety	Standard spelling	Nonstandard form
American English	height	heighth
British English	height	heighth
Canadian English	height	heighth
Australian English	height	heighth
International English	height	heighth

Unlike words such as colour/color, centre/center, and travelling/traveling, height does not normally change spelling between British and American English.

For example:

• British English: The height of the wall is three metres
• American English: The height of the wall is ten feet
• Canadian English: The height of the tower is impressive

The spelling remains height in each case.

Which Spelling Should You Use?

For US English

Use height. This is the standard form for schools, businesses, websites, reports, and everyday writing.

Example:
The athlete’s height is six feet.

For UK and Commonwealth English

Use height as well. British and Commonwealth writers do not normally use heighth in standard writing.

Example:
The height of the building is 50 metres.

For global English

If your audience is international, height is the safest choice. It is widely understood and recognized as the standard form.

If you see heighth in an old book, historical document, regional speech, or a quotation, it may reflect older or dialectal usage. 

It does not mean you should use that spelling in normal modern writing.

Common Mistakes with Heighth or Height

The most common mistake is adding -th to the end of height.

Incorrect	Correct
heighth	height
heighths	heights
the heighth of the building	the height of the building
maximum heighth	maximum height
minimum heighth	minimum height
average heighth	average height

Another common error is confusing height with words such as high and eighth.

Remember:

• high = describes something far above the ground
• height = the measurement or level of something
• eighth = number eight in a sequence

For example:

Correct:
The mountain has a great height.

Correct:
The mountain is very high.

Correct:
She finished eighth in the race.

A Simple Memory Trick

Think of height as a word that ends in -ght, not -ghth.

You can also connect it with:

• height
• weight
• eight

The spelling height contains the letters eight after the initial h, although its pronunciation is different.

Heighth or Height Google Trends & Usage Data

Search interest for height is far greater than interest in heighth. 

Available search-focused sources consistently describe height as the dominant form, while heighth has very limited modern usage.

• Human height

• Product dimensions

By contrast, searches for heighth are mainly connected with spelling questions, pronunciation questions, dialect discussions, or attempts to check whether the word is correct.

It is important not to treat small search differences as proof of a regional spelling rule. Heighth is not a British-versus-American spelling choice. 

It is generally treated as a nonstandard or dialectal form. Collins, for example, labels it a nonstandard spelling of height.

Historical language data also show that forms such as heighth and highth have existed for a long time. 

Their historical presence explains why some speakers may still encounter or use them, even though height is the standard modern form.
