What What Kind of vs. What Kinds of becomes clear when you match the expression with the noun, sentence structure, and subject-verb agreement in English. The phrase what kind of is normally used when you are asking about one type or a general category, while what kinds of refers to more than one type or multiple categories.
These grammar patterns are useful for English learners who may feel confused when asking questions in conversations or academic writing. For correct usage, check the noun that follows the expression and consider whether the meaning is singular or plural.
Real-life examples, real sentence examples, and easy grammar explanations can make the difference between what kind of and what kinds of easier to apply in everyday English. A useful practical tip is to read the whole question before choosing the right expression, which can help a learner sound more natural and confident while avoiding common mistakes.
Quick Answer
“What kind of” usually asks about one type, category, or general variety.
- What kind of car do you drive?
- What kind of music do you enjoy?
- What kind of books does she read?
“What kinds of” usually asks about multiple types, categories, or varieties.
- What kinds of cars are popular in your area?
- What kinds of music do you listen to?
- What kinds of books does the library contain?
The important point is that “what kind of” can appear before plural nouns. For example, “What kind of books do you recommend?” is perfectly natural.
Think of it this way:
One category or general type → “what kind of”
Several categories or varieties → “what kinds of”
Comparison Overview
The difference between what kind of and what kinds of becomes clearer when you focus on the meaning rather than simply counting nouns.
| Feature | What Kind Of | What Kinds Of |
| Form of kind | Singular | Plural |
| Main meaning | One type or category | Multiple types or categories |
| Common use | General classification | Variety or several classifications |
| Can precede plural nouns? | Yes | Yes |
| Can precede uncountable nouns? | Yes | Yes |
| Example | What kind of movie do you like? | What kinds of movies do you like? |
| Typical emphasis | One broad type | Several distinct types |
For example, imagine someone asks about music.
What kind of music do you like?
This can mean, “What type of music do you generally enjoy?” You might answer, “I like jazz.”
Now consider:
What kinds of music do you like?
This question puts more emphasis on variety. You might answer, “I like jazz, rock, classical music, and folk music.”
Neither question is automatically wrong. The speaker simply frames the category differently.
Main Differences Between What Kind Of vs. What Kinds Of
The central difference lies in number and classification. Kind is singular, while kinds is plural. Yet the noun after of doesn’t necessarily have to match that number.
“What Kind Of” Refers to One Type or General Category
Use what kind of when you have one broad type or category in mind.
For example:
- What kind of food do you like?
- What kind of car does he own?
- What kind of music is playing?
- What kind of job are you looking for?
In each question, the speaker asks for a classification.
Suppose someone asks, “What kind of car do you want?” The answer might be “an SUV,” “a sports car,” or “an electric vehicle.” The question asks the listener to identify a category.
The category can be broad. It doesn’t have to represent literally one physical object.
“What Kinds Of” Refers to Multiple Types or Varieties
Use what kinds of when you want to emphasize more than one category.
For example:
- What kinds of cars are available?
- What kinds of food do they serve?
- What kinds of jobs are available in this field?
- What kinds of problems can this method solve?
Here, the plural kinds suggests that several categories may be relevant.
If a restaurant offers Italian, Mexican, Thai, and Indian cuisine, asking “What kinds of food do you serve?” naturally invites a list of different varieties.
The Noun After “Of” Doesn’t Decide the Answer
This is where many learners get tripped up.
You might see:
What kind of books do you read?
The word books is plural, but kind remains singular. That’s completely normal.
Why? Because kind describes the category while books identifies the items within that category.
The question can be understood as asking, “What type of books do you read?”
Now compare it with:
What kinds of books do you read?
This version emphasizes multiple categories. Perhaps the expected answer is “mystery novels, biographies, science books, and historical fiction.”
So don’t automatically choose kinds just because the noun is plural.
What Does “What Kind Of” Mean?
What kind of is a common English expression used to ask about a type, sort, category, or variety.
What Kind Of With Singular Countable Nouns
When the noun describes one countable item, what kind of is especially straightforward.
Examples include:
- What kind of car is that?
- What kind of phone do you use?
- What kind of animal is it?
- What kind of cake should we order?
Here, the question asks you to classify a single thing.
If someone points toward an unfamiliar vehicle and asks, “What kind of car is that?”, they want to know its type, model category, or perhaps its general classification.
What Kind Of With Plural Nouns
Surprisingly, what kind of also works naturally with plural nouns.
Consider:
- What kind of movies do you enjoy?
- What kind of shoes do you need?
- What kind of books should I buy?
- What kind of restaurants do you prefer?
The plural noun doesn’t force kind to become plural.
For instance, “What kind of movies do you like?” often means, “What type or genre of movies do you like?”
A natural answer could be:
“Mostly science fiction movies.”
The speaker has treated science fiction as one category even though that category contains many individual movies.
What Kind Of With Uncountable Nouns
What kind of also frequently appears before 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 coffee do you prefer?
Words such as music, advice, and information generally function as uncountable nouns in standard English.
The phrase what kind of helps divide those broad concepts into categories or varieties.
What Does “What Kinds Of” Mean?
What kinds of emphasizes multiple types, varieties, or categories.
What Kinds Of With Plural Countable Nouns
This structure works naturally when you expect several categories.
Examples:
- What kinds of books are popular right now?
- What kinds of cars does the company manufacture?
- What kinds of jobs can you get with this degree?
- What kinds of animals live in this region?
The plural kinds signals variety.
For example, if a bookstore carries novels, biographies, textbooks, poetry, and travel books, “What kinds of books do you sell?” is a natural question.
What Kinds Of With Uncountable Nouns
Uncountable nouns can also follow what kinds of when you mean different varieties.
For example:
- What kinds of music are popular there?
- What kinds of food does the restaurant serve?
- What kinds of cheese are available?
- What kinds of information does the report contain?
Although food, music, and information can be uncountable, they can represent multiple varieties or categories.
Think of kinds as dividing a large umbrella into several smaller sections.
Can “What Kind Of” Be Used With Plural Nouns?
Yes. What kind of + plural noun is grammatically correct and extremely common.
Consider:
What kind of books do you read?
The phrase doesn’t mean that you read only one book. Instead, kind refers to one category or general type of book.
For example, you might answer:
“I mostly read historical novels.”
The category is singular: historical novels as a genre or type. The individual books are plural.
Now compare:
What kinds of books do you read?
That question can invite a broader answer:
“I read historical novels, biographies, science books, and travel guides.”
The difference is subtle but meaningful.
| Question | Likely Focus |
| What kind of books do you read? | A general type or category |
| What kinds of books do you read? | Several types or categories |
Still, real conversations aren’t mathematical formulas. A speaker may use either form depending on how they conceptualize the subject.

Can “What Kinds Of” Be Used With Uncountable Nouns?
Yes. What kinds of can describe different varieties within an uncountable category.
Take the word coffee.
You can ask:
What kind of coffee do you drink?
This sounds like you’re asking about a general preference or type.
You can also ask:
What kinds of coffee do you sell?
Here, the plural kinds highlights the different varieties available.
The same principle applies to other nouns:
- What kind of cheese do you like?
- What kinds of cheese are sold here?
- What kind of music do you enjoy?
- What kinds of music are performed at the festival?
The noun itself doesn’t determine whether kind or kinds must appear. The intended classification does.
What Kind Of vs. What Kinds Of With Common Nouns
Looking at different noun types makes the distinction much easier to remember.
With Singular Countable Nouns
Use what kind of naturally when asking about a single item.
Examples:
- What kind of car is this?
- What kind of phone is that?
- What kind of flower is growing there?
Using what kinds of with a singular noun usually creates a mismatch in meaning because a single object isn’t normally being divided into several types.
With Plural Countable Nouns
Both structures can work.
- What kind of books do you read?
- What kinds of books do you read?
The first can focus on one broad category. The second can emphasize several categories.
That’s why the simple rule “plural noun = kinds” doesn’t work.
With Uncountable Nouns
Both forms can also work with uncountable nouns.
- What kind of information do you need?
- What kinds of information do you need?
The first treats the request as one general category of information. The second highlights multiple types of information.
The distinction comes from the speaker’s intended meaning.
What Kind Of vs. What Kinds Of: How Context Changes the Meaning
Context often settles the question better than grammar rules alone.
Imagine you’re helping a friend choose a movie.
Question: What kind of movie do you want to watch?
Your friend might say, “A comedy.”
The question seeks one general genre.
Now imagine you’re planning a movie festival.
Question: What kinds of movies should we include?
A natural answer could list several genres: comedy, drama, science fiction, documentary, and animation.
The subject remains movies in both sentences. Only the classification focus changes.
Another Practical Example: Food
Suppose you’re asking someone about a single meal preference:
What kind of food do you like?
They might answer:
“I love Mexican food.”
If you’re asking a restaurant about its menu, you might say:
What kinds of food do you serve?
The response could include several cuisines.
This distinction is especially useful in interviews, surveys, customer conversations, and everyday questions.
What Kind Of vs. What Kinds Of in Questions and Answers
The answer someone expects can reveal the intended meaning.
Example: Exercise
What kind of exercise do you do?
Possible answer:
“Mostly strength training.”
The response identifies a general category.
What kinds of exercise do you do?
Possible answer:
“I lift weights, swim, cycle, and walk.”
The plural question encourages several categories or activities.
Example: Books
What kind of books do you enjoy?
Possible answer:
“Historical fiction.”
What kinds of books do you enjoy?
Possible answer:
“Historical fiction, biographies, mysteries, and science books.”
Again, both questions can be grammatical. The second simply places greater emphasis on variety.
What Kind Of vs. What Kinds Of in American English
In everyday US English, what kind of is extremely common.
You’ll hear it in casual conversations, interviews, classrooms, workplaces, stores, and countless other situations.
For example:
- What kind of work do you do?
- What kind of music do you listen to?
- What kind of problems are you having?
- What kind of books are you looking for?
Notice that some of these nouns are plural.
American English speakers don’t generally treat what kind of as grammatically wrong simply because the noun after of is plural.
At the same time, what kinds of remains useful when the speaker specifically wants to emphasize multiple varieties.
What Kind Of vs. What Kinds Of in Formal and Informal Writing
Both forms work in formal and informal contexts when their meanings fit.
In everyday conversation, you might ask:
What kind of work are you looking for?
In a report, a researcher might write:
What kinds of factors influence consumer behavior?
The second sentence emphasizes several categories of factors.
Formal writing may use what kinds of when researchers, analysts, or writers need to distinguish several classes of things. However, what kind of isn’t inherently informal.
The real issue is meaning and context, not formality alone.
FAQs:
1. What is the difference between what kind of and what kinds of?
What kind of usually asks about one type or category, while what kinds of asks about multiple types or categories. For example, “What kind of music do you like?” refers to a general type of music, while “What kinds of music do you listen to?” can refer to several different genres.
2. Is what kind of singular or plural?
What kind of is followed by a singular countable noun when you mean one type. For example, “What kind of book are you reading?” Here, “book” is singular. However, what kind of can also be followed by an uncountable noun, such as “What kind of advice do you need?”
3. When should I use what kinds of?
Use what kinds of when you are asking about more than one type or several categories. For example, “What kinds of sports do you enjoy?” suggests that the answer may include basketball, tennis, soccer, or other sports.
4. Is what kind of always followed by a singular noun?
No. Although what kind of commonly appears before a singular countable noun, it can also come before an uncountable noun. For example, “What kind of food do you like?” uses the uncountable noun “food.” The correct choice depends on the meaning and noun form.
5. Which is correct: what kind of or what kinds of?
Both expressions are correct, but they are used in different situations. Choose what kind of for one type or a general category and what kinds of for multiple types. Checking the noun, sentence structure, and intended meaning will help you make the right choice.
Conclusion:
Understanding what kind of vs. what kinds of is easier when you focus on whether you mean one type or multiple types. Use what kind of for a single type or general category, and use what kinds of when referring to several types or categories. Paying attention to the noun that follows the phrase and the overall question can help you avoid common mistakes. With regular practice and real sentence examples, you can use both expressions naturally and confidently in everyday English, conversations, and academic writing.
