“What kind of” and “what kinds of” are both correct English expressions, but they are not always used in exactly the same way. The difference usually comes down to whether you are talking about one general type or several different types.
You might ask, “What kind of music do you listen to?” when asking generally about someone’s musical preference. However, “What kinds of books do you read?” suggests that you expect the person to name several categories, such as mysteries, biographies, and science fiction.
The difference is small, but understanding it can make your questions sound clearer and more natural.
Quick Answer
Use “what kind of” when asking about one type, category, or general class of something.
Example:
What kind of phone do you have?
Use “what kinds of” when asking about several types or categories.
Example:
What kinds of phones does the company sell?
A simple way to remember the difference is:
Kind = one type
Kinds = several types
The noun that follows the phrase also gives you an important clue about which form to choose.
What Kind of vs What Kinds of
Here is a simple comparison:
| Phrase | Usually Refers To | Common Noun Form | Example |
|---|---|---|---|
| What kind of | One type or general category | Singular or uncountable | What kind of tea do you drink? |
| What kinds of | Several types or categories | Plural | What kinds of teas are available? |
Both expressions ask someone to identify or describe a category. The main difference is whether you are thinking about one category broadly or several categories separately.
What Does “What Kind of” Mean?
“What kind of” is used when asking what type or category something belongs to.
For example:
What kind of movie is this?
What kind of job are you looking for?
What kind of computer does she use?
What kind of food should we order?
In these examples, the speaker is asking for a general description or category.
“What kind of” is also commonly used before uncountable nouns.
For example:
What kind of music do you enjoy?
What kind of advice did he give you?
What kind of information do they need?
Words such as “music,” “advice,” and “information” are generally treated as uncountable nouns, so “what kind of” sounds natural with them.
What Does “What Kinds of” Mean?
“What kinds of” asks about more than one type or category.
For example:
What kinds of movies do you enjoy?
What kinds of exercises do you do?
What kinds of vegetables grow here?
What kinds of problems did you experience?
The speaker expects several possible answers or categories.
If someone asks, “What kinds of movies do you watch?” you might answer:
Comedy, action, documentaries, and thrillers.
Because several categories are being discussed, the plural word “kinds” fits naturally.
Singular and Plural Rule
The easiest grammar rule is to look at the noun following the phrase.
Use:
What kind of + singular or uncountable noun
Examples:
What kind of camera do you own?
What kind of coffee do you prefer?
What kind of software does the company use?
Use:
What kinds of + plural noun
Examples:
What kinds of cameras do professionals use?
What kinds of coffees are sold here?
What kinds of software programs are popular with designers?
This rule works in most everyday situations.
Sentence Patterns
Knowing the basic sentence structure can make the difference even easier to understand.
For “what kind of”:
What kind of + noun + verb?
Examples:
What kind of car does your brother drive?
What kind of music helps you concentrate?
What kind of restaurant is this?
For “what kinds of”:
What kinds of + plural noun + verb?
Examples:
What kinds of cars do they manufacture?
What kinds of activities does the school offer?
What kinds of restaurants are popular in this area?
Once you become familiar with these patterns, choosing between “kind” and “kinds” becomes much easier.
Examples of “What Kind of”
Here are a few natural examples:
What kind of laptop should I buy?
What kind of weather do you prefer?
What kind of person would enjoy this job?
What kind of dog is that?
What kind of training does the position require?
What kind of dessert are you making?
Notice that these questions focus on one general category or description.
Someone asking “What kind of dog is that?” probably wants to know the breed or type rather than receive a list of different dogs.
Examples of “What Kinds of”
Now compare these examples:
What kinds of dogs are good for families?
What kinds of desserts can we make without an oven?
What kinds of jobs are available in this industry?
What kinds of plants grow well indoors?
What kinds of games do your children play?
What kinds of questions appear on the test?
These questions invite multiple answers.
For instance, an answer to “What kinds of plants grow well indoors?” could include pothos, snake plants, spider plants, and peace lilies.
Common Mistakes
One frequent mistake is using “kinds” with a singular noun.
Incorrect:
What kinds of book do you like?
Correct:
What kinds of books do you like?
Because “kinds” refers to several categories, the noun “books” should normally be plural.
Another common error is using a plural structure with an uncountable noun.
Awkward:
What kinds of information do you need?
More natural:
What kind of information do you need?
However, there are situations where “kinds of information” can be correct if you are deliberately talking about several distinct categories of information.
For example:
What kinds of information are collected during the survey?
Here, the speaker may be asking about categories such as age, occupation, education, and location.
Context can sometimes change what sounds appropriate.
Can Both Forms Be Correct?
Yes. Sometimes both versions are grammatically correct, but their meanings are slightly different.
Compare:
What kind of cake do you like?
What kinds of cakes do you like?
The first question asks generally about the type of cake someone prefers.
A person might answer:
Chocolate cake.
The second question encourages the person to mention several varieties.
They might answer:
Chocolate cake, carrot cake, cheesecake, and fruit cake.
Another example:
What kind of sport do you play?
This may suggest that the speaker expects one main answer.
What kinds of sports do you play?
This suggests that the speaker thinks the person may play several sports.
The choice between the two often depends on what kind of answer you expect.
What Kind of vs What Type of
“What kind of” and “what type of” often have nearly the same meaning.
For example:
What kind of computer do you use?
What type of computer do you use?
Both are correct.
However, “what kind of” is very common in everyday conversation, while “what type of” can sometimes sound slightly more formal, technical, or precise.
You might hear:
What kind of movies do you like?
in a casual conversation.
A technician might instead ask:
What type of operating system are you using?
There is no strict rule requiring one expression in every situation. Tone and context often determine which sounds better.
Which One Sounds More Natural?
Both expressions are natural when they match the intended meaning.
“What kind of” appears very frequently in casual speech because people often ask about something as a general category.
For example:
What kind of music is playing?
What kind of food do you want tonight?
“What kinds of” becomes useful when the conversation clearly involves several categories.
For example:
What kinds of music are taught at the school?
What kinds of food are served at the festival?
Think about the answer you expect. If you expect one broad category, “what kind of” is usually suitable. If you expect a list of categories, “what kinds of” may be better.
Easy Trick to Remember
There is a very simple memory trick:
One category = what kind of
Several categories = what kinds of
Then check the noun.
Singular:
What kind of movie is it?
Plural:
What kinds of movies are available?
You can also imagine replacing “kind” with “type.”
What type of movie?
What types of movies?
If “type” sounds right, “kind” usually works. If “types” sounds right, “kinds” usually works.

Final Thoughts
The difference between “what kind of” and “what kinds of” becomes simple once you think about the number of categories involved.
Use “what kind of” when asking about one general type or category. It also works naturally with many uncountable nouns.
Use “what kinds of” when you want to ask about several different types or categories, usually followed by a plural noun.
Compare these two questions one final time:

What kinds of books do you usually read?
The first focuses on one book and its type. The second asks about several categories of books.
