What Kind of vs What Kinds of can seem confusing when you have paused mid-sentence and wondered what to say. These phrases look almost identical, but their slightly different purposes matter in English grammar: what kind of usually refers to one type or a general category, while what kinds of refers to more than one type or multiple categories.
For example, what kind of music asks about a general type of music, while what kinds of music can ask about several types. The key difference becomes easier when you connect the expressions to the noun. When asking about something, the right expression can make your speech and writing sound more natural, clearer, and more confident.
English learners are often confused because the difference is small, yet the choice can affect sentence clarity, sentence structure, and natural English usage. The basic grammar rules are simple to apply: what kind of commonly comes before a singular noun, whereas what kinds of commonly comes before plural nouns.
Quick Answer
Both “what kind of” and “what kinds of” are correct. The best choice depends on what you mean.
- What kind of usually asks about one general type, category, or nature.
- What kinds of usually asks about multiple types, categories, or varieties.
- What kind of can be followed by a singular noun, plural noun, or uncountable noun.
- What kinds of normally takes a plural noun when it refers to multiple categories.
- You shouldn’t decide between them based only on whether the following noun is singular or plural.
Consider these examples:
| Expression | Example | Main idea |
| What kind of | What kind of car do you drive? | One general type |
| What kind of | What kind of cars do you like? | General category |
| What kind of | What kind of music do you enjoy? | General type or style |
| What kinds of | What kinds of cars do you like? | Multiple types |
| What kinds of | What kinds of music do you enjoy? | Several varieties or genres |
The simplest rule is this: use “what kind of” for a general category and “what kinds of” when you want to emphasize multiple categories.
Comparison Overview
| Feature | What Kind of | What Kinds of |
| Form of “kind” | Singular | Plural |
| Basic meaning | One type or general category | Multiple types or categories |
| Singular countable noun | Yes | Usually no |
| Plural countable noun | Yes | Yes |
| Uncountable noun | Yes | Sometimes, depending on meaning |
| Focus | General classification | Variety or multiple classifications |
| Example | What kind of book is this? | What kinds of books do you read? |
| Common in everyday English | Very common | Very common |
| Always determined by noun number? | No | No |
The important point is that kind doesn’t have to agree mechanically with the noun that follows of. The phrase “what kind of” often works as a unit that asks about the general category of something.
For instance, “What kind of movies do you watch?” doesn’t sound incorrect just because movies is plural. The speaker may simply want to know the general type of movies the listener prefers.
By contrast, “What kinds of movies do you watch?” places greater emphasis on the possibility of different movie categories, such as comedies, dramas, thrillers, documentaries, or science fiction.
Main Differences Between What Kind of vs What Kinds of
The distinction between what kind of and what kinds of becomes clearer when you focus on the speaker’s intended meaning. The words aren’t merely different grammatical forms. They can give a question a slightly different scope.
What Kind of Usually Refers to a General Type
The singular kind often works when you’re asking someone to identify a broad category.
Imagine someone tells you, “I bought a new car.” You might respond:
What kind of car did you buy?
You’re probably not asking them to list every possible category of car. You simply want to know the type. Their answer might be an electric car, a sports car, an SUV, or a hybrid.
Here are some natural examples:
- What kind of food do you like?
- What kind of job are you looking for?
- What kind of music do you listen to?
- What kind of person is she?
- What kind of computer do you use?
- What kind of books do you enjoy?
Notice something important: some of these nouns are plural.
“What kind of books do you enjoy?” is grammatically natural because kind refers to the general category of books being discussed. The plural noun books doesn’t automatically force the phrase to become what kinds of.
What Kinds of Emphasizes Multiple Types
The plural kinds draws attention to different varieties or categories.
Suppose you’re interviewing someone about their reading habits. You could ask:
What kinds of books do you read?
This question can invite an answer such as:
- mystery novels
- biographies
- historical fiction
- science books
- travel writing
The wording suggests that you expect the person may read several different types.
That’s the key difference. “What kind of books” can ask about a general preference, while “what kinds of books” can highlight variety.
What Kind of Can Come Before Plural Nouns
This is one of the most useful facts to remember.
A common learner assumption says:
Singular kind → singular noun
Plural kinds → plural noun
That shortcut doesn’t accurately describe English usage.
You can naturally say:
- What kind of movies do you like?
- What kind of shoes do you wear?
- What kind of books do you read?
- What kind of restaurants do you prefer?
- What kind of cars interest you?
In each case, the noun is plural, yet what kind of remains completely acceptable.
Why? Because the speaker isn’t necessarily asking about several categories. The speaker may be asking for a general classification or preference.
Compare:
What kind of books do you read?
This can mean, “What general type of books do you tend to read?”
What kinds of books do you read?
This more strongly suggests, “Which different categories of books do you read?”
The difference is subtle. In everyday conversation, the two questions can overlap considerably.
What Kinds of Normally Works With Plural Countable Nouns
Because kinds is plural, it naturally fits situations where you are talking about several categories.
For example:
- What kinds of cars are available?
- What kinds of jobs require this degree?
- What kinds of animals live here?
- What kinds of problems can occur?
- What kinds of movies are popular with teenagers?
Here, the plural construction makes the idea of variety more obvious.
If a store sells several categories of shoes, for example, someone might ask:
What kinds of shoes do you sell?
The expected answer could mention running shoes, hiking boots, dress shoes, sandals, and work shoes.
The Difference Is Often About Scope
Think of kind as a camera lens.
With what kind of, the lens often zooms out. You’re asking for a broad classification.
With what kinds of, the lens can zoom in on the different categories within that larger field.
For example:
- What kind of food do you serve? → What general type of food?
- What kinds of food do you serve? → What different varieties or categories?
Both questions can receive similar answers. However, the second wording makes variety more prominent.
What Does “What Kind Of” Mean?
What kind of is a question phrase used to ask about the type, category, nature, or characteristics of something.
Its basic structure is:
What kind of + noun
For example:
What kind of phone do you have?
The phrase asks the listener to identify the phone’s general type or category.
It doesn’t necessarily mean that only one item exists. Instead, kind can identify the category to which something belongs.
“What Kind Of” With Singular Nouns
This is the most straightforward pattern.
Examples include:
- What kind of car is that?
- What kind of person is he?
- What kind of movie is this?
- What kind of job does she have?
- What kind of animal is that?
Here, the question generally seeks one classification.
If someone points toward a strange-looking vehicle, you might ask:
What kind of car is that?
You want to know what type of vehicle you’re looking at.
“What Kind Of” With Plural Nouns
The plural noun pattern deserves special attention because it often causes confusion.
Examples include:
- What kind of books do you buy?
- What kind of shoes do you need?
- What kind of movies do you watch?
- What kind of restaurants do you visit?
These sentences don’t become incorrect simply because the nouns are plural.
The phrase can describe a general class of things rather than one specific object.
“What Kind Of” With Uncountable Nouns
What kind of works especially naturally with uncountable nouns.
Examples include:
- What kind of music do you like?
- What kind of advice do you need?
- What kind of information are you looking for?
- What kind of equipment do we need?
- What kind of furniture should we buy?
You can’t normally count music or information as individual objects in these contexts. Yet you can still ask about their type or variety.

What Does “What Kinds Of” Mean?
What kinds of uses the plural noun kinds to emphasize different types, categories, or varieties.
Its common structure is:
What kinds of + plural noun
For example:
What kinds of books are available?
The question focuses on the different categories of books available.
Examples of “What Kinds Of”
Here are several natural examples:
- What kinds of books do you enjoy?
- What kinds of food are popular there?
- What kinds of cars do they manufacture?
- What kinds of skills does the job require?
- What kinds of problems might we encounter?
- What kinds of activities do children enjoy?
The plural kinds becomes useful when the idea of variety matters.
Why “Kinds” Changes the Focus
Suppose a friend says, “I like books.”
You ask:
What kind of books do you like?
You’re asking about their general reading preference.
Now imagine you’re conducting a survey and want respondents to list several categories. You might ask:
What kinds of books do you like?
The second version encourages a broader answer.
It isn’t necessarily a completely different question. Rather, the plural form makes the range of categories more noticeable.
What Kind of vs. What Kinds of With Plural Nouns
This is where many grammar explanations become too rigid.
Consider these two sentences:
What kind of cars do you like?
What kinds of cars do you like?
Both are grammatical.
The first may ask about the person’s general preference. Perhaps the answer is simply, “I like electric cars.”
The second may encourage a list: “I like electric cars, sports cars, and SUVs.”
Neither sentence is automatically right or wrong without considering context.
Side-by-Side Meaning
| Sentence | Possible interpretation |
| What kind of books do you read? | What general type of books do you tend to read? |
| What kinds of books do you read? | What different categories of books do you read? |
| What kind of music do you like? | What general style or type of music? |
| What kinds of music do you like? | Which different genres or varieties? |
| What kind of food do you eat? | What general type of food? |
| What kinds of food do you eat? | What different types or varieties? |
The distinction isn’t always sharp. Native speakers may use both expressions in similar situations.
What Kind of vs. What Kinds of in Everyday Questions
In casual American English, what kind of appears extremely often.
People use it when asking about preferences, descriptions, categories, and characteristics.
For example:
- What kind of coffee do you want?
- What kind of music are you into?
- What kind of phone do you have?
- What kind of work do you do?
- What kind of movies do you watch?
These questions sound natural because the speaker usually wants a broad answer.
Meanwhile, what kinds of becomes particularly useful when the question explicitly concerns variety.
For example:
- What kinds of coffee does the shop sell?
- What kinds of music are played at the festival?
- What kinds of phones are available?
- What kinds of movies are shown at the theater?
The surrounding context often tells you which form feels more appropriate.
What Kind of vs. What Kinds of in Formal Writing
Both expressions can appear in formal and informal writing. Neither one is inherently too casual for professional or academic contexts.
For example:
What kind of evidence supports this conclusion?
This sounds perfectly appropriate in formal writing.
You could also write:
What kinds of evidence support this conclusion?
The second version suggests that several forms or categories of evidence may be involved.
A useful distinction is therefore precision rather than formality.
Choose the wording that communicates the intended scope most clearly.
Academic Example
Consider:
What kind of research method was used?
This asks for the general research method.
Now compare:
What kinds of research methods are commonly used?
This asks about multiple methods.
The difference comes from the intended scope rather than the level of formality.
Common Mistakes With What Kind of and What Kinds of
Mistake: Thinking Plural Nouns Require Kinds
This rule is too simplistic:
“The noun is plural, so I must use kinds.”
That’s not how English works.
What kind of books do you read? is perfectly natural.
The plural noun doesn’t force kind to become plural.
FAQs:

2. Is “what kind of” singular or plural?
What kind of is generally followed by a singular noun when you are identifying one type or category. For example, “What kind of book are you reading?” Here, book is singular.

Use what kinds of when you are asking about multiple types, varieties, or categories. For example, “What kinds of books do you enjoy?” refers to more than one possible type of book.
4. Can “what kind of” be used with plural nouns?
Yes. In everyday English, what kind of can sometimes appear before a plural noun when “kind” refers to a general category rather than a single item. For example, “What kind of books do you usually read?” is natural English. The choice depends on the meaning you want to express.
5. Which is more natural: “what kind of music” or “what kinds of music”?

Conclusion:
The difference between what kind of and what kinds of mainly depends on whether you are thinking about one general type or several types. What kind of commonly introduces a singular category, while what kinds of highlights multiple categories or varieties. Once you understand this basic pattern, choosing between the two becomes much easier.
Pay attention to the noun that follows the phrase and to the meaning of your question. With regular practice and real examples, you can use both expressions naturally in conversations, academic writing, and everyday English.
