Standardize and standardise are two spellings of the same verb, meaning to make something uniform, consistent, or compliant with a standard. Standardize is the preferred spelling in American English, while standardise is commonly used in British English and other varieties of English.
If you’re searching for “standardize vs standardise,” “standardise or standardize,” or “standardize or standardise,” the main difference is regional spelling, not meaning. Both forms mean to establish or follow a consistent standard for something. The spelling with -ize is standard in American English, while -ise is widely used in British English.

Standardize vs Standardise: Quick Answer
| Form | American English | British English |
| Base verb | standardize | standardise |
| Third person | standardizes | standardises |
| Past tense | standardized | standardised |
| Present participle | standardizing | standardising |
| Noun | standardization | standardisation |
The easiest way to remember the difference is:
US English → standardize
UK English → standardise
Cambridge lists standardize as the main form and notes that UK English usually uses standardise. Oxford also lists standardise as a British English form.
What Does Standardise Mean?
Standardise means to make things of the same type follow the same standard or have the same basic features.
It is a verb.
For example:
- The company wants to standardise its procedures.
- Schools should standardise their testing methods.
- The manufacturer plans to standardise its product sizes.
- The organization decided to standardise its reporting system.
In American English, each sentence would use standardize instead.
The central idea is consistency. When you standardize something, you reduce unnecessary differences and make it follow an accepted or consistent standard.
Cambridge explains the verb as making things of the same type have the same basic features. Oxford similarly describes standardize as making objects or activities of the same type share the same features or qualities.
Standardize vs Standardise Meaning
There is no important difference in meaning between standardize and standardise.
Both words can mean:
- to make something conform to a standard
- to make similar things more consistent
- to create uniform procedures or features
- to make something follow an accepted model
- to reduce unnecessary variation
For example:
The company plans to standardize its manufacturing process.
British English can write:
The company plans to standardise its manufacturing process.
The meaning remains exactly the same.
The spelling changes because American and British English often use different endings for certain verbs.
Standardize or Standardise: Which Is Correct?

Standardize vs Standardise in American and British English
The difference extends beyond the base verb.
American English generally uses z, while British English commonly uses s in this word family.
| Word form | American English | British English |

| Past tense | standardized | standardised |
| Past participle | standardized | standardised |
| Present participle | standardizing | standardising |

Standardize Spelling: How to Remember It
If you often confuse standardize and standardise, focus on the variety of English you are using.
American English
standardize
Think:
US → Z → standardize
British English
standardise
Think:
UK → S → standardise
The same pattern appears in the related forms:
US: standardizes, standardized, standardizing, standardization
UK: standardises, standardised, standardising, standardisation
One important point remains: British English does not always require s instead of z in every word. English spelling conventions have exceptions, and individual dictionaries can recognize multiple forms. For this word family, however, the US z and UK s distinction is straightforward. Cambridge and Oxford both recognize the relationship between the two forms.
Is Standardise Wrong in American English?
Standardise is understandable to American readers, but standardize is the normal spelling for standard American English.
If you are writing for a US audience, choose:
standardize
If you are writing for a British audience, choose:
standardise
The best approach is to follow one spelling system consistently.
Is Standardize Wrong in British English?
No.
British English recognizes standardize, although standardise is commonly used in UK writing. Oxford specifically lists standardise as a British English form, while Cambridge labels standardise as the usual UK form.
Therefore, it would be inaccurate to call standardize an incorrect word in British English.
The real difference concerns regional spelling preference.
Common Mistakes With Standardize and Standardise
1. Thinking One Spelling Is Completely Wrong
Both forms are legitimate.
The spelling depends on the English variety.
2. Mixing US and UK Forms
A writer may use standardize in one paragraph and standardise in another.
That inconsistency can make the writing look careless.
Choose one form and use it throughout the document.
3. Mixing Related Word Forms
The same problem can occur with the other forms.
For example:
The company will standardize its procedures while standardising its reports.
The reader can understand the sentence, but it mixes American and British spelling.
For American English, use:
The company will standardize its procedures while standardizing its reports.
For British English, use:
The company will standardise its procedures while standardising its reports.
4. Confusing Standardize With Standard
Standardize is a verb.
Standard can be a noun, adjective, or verb depending on the sentence.
For example:
The company wants to standardize its procedures.
Here, standardize means to make the procedures follow a consistent standard.
By contrast:
The company follows a high standard.
Here, standard is a noun.
5. Assuming Standardize Means “Make Better”
Standardize does not automatically mean improve.
It means to make something conform to a standard or become more consistent.
A standardized process may be better in some situations, but the word itself focuses on consistency, not necessarily quality.
