Have you ever paused while writing a sentence and wondered whether you should say “what kind of” or “what kinds of”? It’s one of those grammar questions that seems simple until you actually need to use it.
Understanding what kind of vs what kinds of is easier than many people think. The difference mainly depends on whether you’re talking about one type or several types of something. In this guide, you’ll learn the grammar rules, see plenty of examples, discover common mistakes to avoid, and gain practical tips that make choosing the right phrase effortless.
What Does “What Kind of” Mean?
What kind of is used when you’re asking about one category, type, or class of something.
Although the answer may include several examples, the question focuses on identifying a single category.
Examples
- What kind of music do you enjoy?
- What kind of phone do you use?
- What kind of dessert should I make?
- What kind of books does she like?
In each example, the speaker wants to know one general type rather than multiple categories.
When to Use “What Kind of”
Use this phrase when referring to:
- One category
- One class
- One type
- One style
- One variety
More examples
- What kind of car is best for families?
- What kind of shoes should I wear?
- What kind of exercise burns the most calories?
- What kind of coffee do you usually drink?
Even though there are many possible answers, the question is still asking for one overall type.
What Does “What Kinds of” Mean?
What kinds of is the plural form. It asks about multiple categories or several different types.
Instead of expecting one classification, the speaker wants information about a range of possibilities.
Examples
- What kinds of movies do you enjoy?
- What kinds of pets are easy to care for?
- What kinds of jobs are available?
- What kinds of plants grow well indoors?
These questions invite answers that include several categories.

- Different classes
- Various options
Examples

What Kind of vs What Kinds of: The Main Difference
The easiest way to remember the difference is this:
| Phrase | Used For | Example |
| What kind of | One category | What kind of tea do you drink? |
| What kinds of | Multiple categories | What kinds of tea are available? |
Think about whether you’re asking for one type or many types.
Singular vs Plural: The Grammar Rule
This distinction follows a simple grammar principle.
Use singular when asking about one category
- What kind of laptop should I buy?
- What kind of language is Spanish?
- What kind of vacation do you prefer?
Use plural when asking about several categories
- What kinds of laptops are best for students?
- What kinds of languages are spoken in Canada?
- What kinds of vacations are popular in winter?
The noun following the phrase often helps you decide.
Understanding the Meaning Through Everyday Examples
Let’s compare similar sentences.
Example 1

This asks for one preferred style.
Possible answer:

What kinds of pizza do you like?

Possible answer:
- Thin crust, deep dish, and stuffed crust.
Example 2
What kind of music do you listen to?
One general category.

Example 3

One preference.

What About “What Kind of a”?
Many English learners notice phrases like:
- What kind of a person…
- What kind of a job…
- What kind of a place…
This often raises questions because both versions seem correct.
Examples
- What kind of person is she?
- What kind of a person is she?
Both are grammatically acceptable.
The version including a is slightly more common in conversational American English, while omitting a is also perfectly natural and is often preferred in formal writing.
When Should You Include “A”?
Use either depending on your style.
With “a”
- What kind of a teacher are you?
- What kind of a movie is this?
- What kind of a solution do you suggest?
Without “a”
- What kind of teacher are you?
- What kind of movie is this?
- What kind of solution do you suggest?
Neither is wrong.
Common Mistakes People Make
Using the Singular for Multiple Categories
Incorrect:
What kind of movies do you like?
This isn’t technically incorrect because many native speakers use it naturally. However, if you’re clearly asking about several categories, what kinds of is more precise.
Better:
What kinds of movies do you like?
Mixing Singular and Plural Incorrectly
Incorrect:
- What kinds of music is your favorite?
Correct:
- What kind of music is your favorite?
- What kinds of music do you enjoy?
Forgetting the Purpose of the Question
Ask yourself:
Am I looking for one category or several?
That simple question usually gives you the answer immediately.
Why Native Speakers Sometimes Mix Them
English is flexible.
In everyday conversation, native speakers often use what kind of even when discussing multiple possibilities.
For example:
What kind of movies do you watch?
Although “movies” is plural, this question is widely accepted because the speaker is asking about someone’s general taste.
However, in careful writing or formal English, using what kinds of when referring to multiple categories is considered clearer.
Practical Tips to Remember the Difference
Here are a few easy tricks.
Tip 1
Think:
- Kind = One
- Kinds = Many
Tip 2
Look at the answer you’re expecting.
If you expect one category:
Use what kind of.
If you expect several categories:
Use what kinds of.
Tip 3
Read the sentence aloud.
Often, the more natural option becomes obvious when spoken.
