What Kind Of vs What Kinds Of: The Difference

A tiny change in wording can completely change the meaning of a question. That is especially true with what kind of vs what kinds of. Both expressions are grammatically correct, but they are used in different situations.

The key is simple: “what kind of” usually asks about one type or category, while “what kinds of” asks about multiple types or categories. Once you understand that distinction, choosing between them becomes much easier.

What Kind Of vs What Kinds Of: The Quick Answer

Use what kind of when you are asking about one type, category, or general class.

What kind of music do you like?

Use what kinds of when you are asking about multiple types or categories.

What kinds of music do you listen to?

However, there is an important detail: in everyday English, what kind of is often used even when the answer may contain several examples. This makes the distinction more flexible than a simple singular-versus-plural rule.

What Kind Of Means

What kind of is one of the most common ways to ask about the type or category of something.

For example:

What kind of car do you drive?

The speaker is asking about the general type of car.

You could answer:

I drive a hybrid.

Or:

I drive a Toyota.

The phrase does not necessarily mean that only one possible answer exists. It simply frames the question around a category or type.

Examples of “what kind of”

• What kind of food do you like?
• What kind of job are you looking for?
• What kind of books do you read?
• What kind of phone do you have?
• What kind of person is he?
• What kind of weather do you prefer?

In everyday conversation, what kind of is extremely natural.

What Kinds Of Means

What kinds of uses the plural kinds and normally emphasizes multiple types or categories.

For example:

What kinds of books do you enjoy?

This question suggests that the speaker is interested in several categories of books.

A possible answer might be:

I enjoy mystery, science fiction, historical fiction, and biographies.

Another example:

What kinds of jobs are available in this field?

The question asks about different categories of jobs rather than focusing on one particular type.

What Kind Of vs What Kinds Of With Plural Nouns

This is where English can become a little confusing.

You might hear:

What kind of books do you read?

Even though books is plural, this sentence can still be perfectly natural.

Why?

Because kind can refer to a general category.

The speaker may essentially be asking:

What type of books do you read?

On the other hand:

What kinds of books do you read?

puts more emphasis on multiple categories.

For example:

What kind of books do you read?

This can invite an answer such as:

Mostly mystery books.

What kinds of books do you read?

This may invite:

Mystery, fantasy, history, and science fiction.

The difference is subtle, but useful.

Is “What Kind Of” Grammatically Correct?

Yes. What kind of is completely standard English.

It can be followed by a singular or plural noun depending on the construction and intended meaning.

Examples include:

What kind of movie is this?

and:

What kind of movies do you usually watch?

Both are natural.

The second sentence does not automatically require what kinds of simply because movies is plural.

Is “What Kinds Of” Grammatically Correct?

Yes. What kinds of is also grammatically correct.

Use it when you want to emphasize different varieties, categories, or types.

For example:

What kinds of exercise do you enjoy?

This suggests multiple forms or categories of exercise.

You could answer:

I enjoy swimming, running, cycling, and yoga.

What Kind Of or What Kinds Of: How to Choose

When deciding between the two, think about what you are actually asking.

Choose “what kind of” when:

• You want to identify a general type.
• You are thinking about one category.
• You want a simple, natural conversational question.
• You are asking about the nature or character of something.

Example:

What kind of restaurant is it?

Choose “what kinds of” when:

• You want several categories.
• You are explicitly asking about different varieties.
• You expect a list of types.
• You want to emphasize diversity or range.

Example:

What kinds of restaurants are available in the area?

What Kind Of vs What Kinds Of: Side-by-Side Examples

What kind of	What kinds of
What kind of music do you like?	What kinds of music do you listen to?
What kind of car do you want?	What kinds of cars does the company sell?
What kind of food do you prefer?	What kinds of foods are popular there?
What kind of book is this?	What kinds of books does she write?
What kind of job do you want?	What kinds of jobs are available?

The distinction is mainly about whether you are focusing on one general category or multiple categories.

“What Kind Of” Can Be Used With Plural Nouns

This is one of the most important points to remember.

Many English learners assume that a plural noun must always be preceded by what kinds of. That is not true.

For example:

What kind of movies do you like?

is perfectly natural.

Here, kind refers to the general category of movies the person enjoys.

You can also say:

What kinds of movies do you like?

This version emphasizes multiple movie categories.

Neither sentence is automatically wrong.

What Kind Of vs What Kinds Of in Formal Writing

Both forms are acceptable in formal and informal English.

The choice should depend on meaning rather than formality.

For example, in an academic discussion, you might write:

What kinds of evidence support this theory?

Here, multiple categories of evidence are being considered.

In a more general question, you might write:

What kind of evidence would support this argument?

This focuses on the type of evidence needed.

Common Mistakes With “What Kind Of”

Mistake 1: Assuming plural always requires “kinds”

Incorrect assumption:

Books is plural, so I must say “what kinds of books.”

Not necessarily.

Both can work:

What kind of books do you enjoy?

What kinds of books do you enjoy?

The intended meaning determines the better choice.

Mistake 2: Treating “kind” and “kinds” as completely interchangeable

They are similar, but they can create a different emphasis.

Compare:

What kind of fruit do you like?

with:

What kinds of fruit do you like?

The first asks more generally about a preferred type.

The second suggests that the speaker wants to know about several types.

Mistake 3: Confusing “kind of” with “kinda”

In informal speech, kind of is sometimes pronounced like kinda.

For example:

I’m kind of tired.

Here, kind of means somewhat or rather.

That is different from:

What kind of music do you like?

In the second sentence, kind of refers to a type or category.

What Kind Kf, What Kind Og, and What Kind Lf

If you have encountered searches such as “what kind kf,” “what kind og,” “what kind of,” or “what kind lf,” the unusual versions are most likely typing errors.

The correct standard spelling is:

what kind of

For example:

What kind of food do you want?

The phrases what kind kf, what kind og, and what kind lf are not standard English expressions.

When typing quickly on a phone or keyboard, letters can easily be entered incorrectly. If you see these variations in search results, use the context to identify the intended phrase.

A Simple Trick to Remember the Difference

Think about whether you want one category or several categories.

One general category:

What kind of music do you like?

Several categories:

What kinds of music are represented at the festival?

A useful memory rule is:

kind = one category

kinds = multiple categories

Just remember that English allows some flexibility, especially when what kind of is used with plural nouns.
