What makes a device a tablet

A tablet is a portable computer with a touchscreen as its main input method — no keyboard or mouse attached. It sits between a smartphone and a laptop in size: typically 7 to 13 inches diagonally measured across the screen. The device runs an operating system designed for touch, usually Apple's iOS, Google's Android, or Microsoft's Windows.

The clearest way to identify one is to look at how you control it. If you tap, swipe, and pinch the screen itself to open apps and navigate, it is a tablet. If it has a physical keyboard you can detach or fold away, it is still a tablet — the touchscreen is the primary control method. If the device requires a separate keyboard and mouse to function normally, it is a laptop or desktop computer, not a tablet.

Key Takeaways

  • A tablet has a touchscreen as its main control method and typically measures between 7 and 13 inches diagonally.
  • Tablets run iOS (Apple), Android (Google), or Windows, and you control them by tapping and swiping the screen.
  • A device with a detachable keyboard is still a tablet if the touchscreen is the primary way you interact with it.
  • Tablets are lighter and thinner than laptops and designed to be held in your hands or propped up on a stand.
  • The operating system and app store (Apple App Store, Google Play, or Microsoft Store) tell you which type of tablet you own.

Screen size and physical shape

Tablets are wider and taller than phones but smaller and lighter than laptops. Most tablets measure between 7 and 13 inches when you measure diagonally from one corner of the screen to the opposite corner. A 7-inch tablet fits easily in one hand; a 13-inch tablet is closer to the size of a sheet of paper and usually sits on a lap or table.

The device is thin — usually less than half an inch thick — and weighs between 1 and 3 pounds depending on the size. You can hold it in portrait mode (taller than wide) or landscape mode (wider than tall), and the screen rotates to match. A laptop, by contrast, is heavier, thicker, and designed to sit on a desk or lap with the screen at a fixed angle.

Operating system and app store

The operating system running on your device tells you what kind of tablet it is. Open the device and look for the name of the maker and the system name. Apple tablets run iOS and are called iPads. Google tablets run Android and are made by Samsung, Google, Amazon, or other manufacturers. Microsoft tablets run Windows and are called Surface tablets or similar names.

You can also identify your tablet by where you read apps. iPad users read from the Apple App Store. Android tablet users read from Google Play. Windows tablet users read from the Microsoft Store. If you open the device and see one of these app stores, you have confirmed what type of tablet you own.

Touchscreen as the main input method

The defining feature of a tablet is that you control it entirely by touching the screen. You tap to open apps, swipe to move between screens, pinch to zoom in and out, and hold your finger on an icon to see options. There is no trackpad or mouse built in, and you do not need one to use the device normally.

Some tablets come with a stylus — a pen-shaped tool that works on the touchscreen — but the stylus is optional. You can use the tablet without it. Some tablets also have a keyboard cover or stand, but the keyboard is not required to use the device. If you cannot use the device without plugging in a keyboard and mouse, it is not a tablet.

Tablet versus laptop: the key differences

A laptop has a built-in keyboard and trackpad that are the main way you control it. A tablet has a touchscreen. A laptop is heavier and thicker, designed to sit on a desk or lap. A tablet is light enough to hold in your hands for extended periods. A laptop runs Windows, macOS, or Linux. A tablet runs iOS, Android, or Windows (though Windows tablets are less common).

Laptops are better for typing long documents, editing photos or video, and running software that requires a keyboard and mouse. Tablets are better for reading, watching video, browsing the web, and using apps designed for touch. Some people use both — a tablet for casual use and a laptop for work that requires a keyboard.

Tablet versus smartphone: the main distinction

The main difference is screen size. A smartphone typically has a screen between 4 and 7 inches. A tablet has a screen between 7 and 13 inches. Both use touchscreens and run similar operating systems (iOS or Android). Both are portable and fit in a bag or backpack.

A tablet is designed to be held with both hands or propped on a stand. A smartphone fits in your pocket. Tablets have larger batteries and longer battery life — often 8 to 12 hours of use compared to a smartphone's 1 to 2 days. Tablets are better for reading, watching movies, and working on documents because the larger screen is easier to see and interact with.

How to check your tablet's specifications

If you are not sure what tablet you own, you can look up its specifications in the settings menu. On an iPad, open Settings, then tap General, then About. You will see the model name, storage capacity, and operating system version. On an Android tablet, open Settings, scroll to the bottom, and tap About tablet or About device. On a Windows tablet, open Settings, then System, then About.

You can also look at the back or bottom of the device. Most tablets have the maker's name printed there — Apple, Samsung, Google, or Microsoft. The model name is usually printed on the back as well. If you still are not sure, you can search the device's model number online to find its specifications and confirm it is a tablet.

Frequently Asked Questions

Is an iPad a tablet?

Yes. iPad is Apple's brand name for its tablet. All iPads are tablets, but not all tablets are iPads. iPad runs iOS and uses the Apple App Store. If you own an iPad, you own a tablet.

Can a tablet have a keyboard attached?

Yes. Many tablets come with a detachable or fold-away keyboard cover. The device is still a tablet because the touchscreen is the main way you control it. The keyboard is optional — you can use the tablet without it. A laptop requires a keyboard to function normally.

What is the difference between a tablet and a 2-in-1 laptop?

A 2-in-1 laptop has a screen that folds back or detaches, but it is designed to work with a keyboard and trackpad as the primary input method. A tablet is designed to work with touch as the primary input method. If the device is marketed as a laptop with a touchscreen, it is a 2-in-1, not a tablet.

How do I know if my device is Android or iOS?

Look at the app store. If you see the Apple App Store, it is iOS (an iPad). If you see Google Play, it is Android. You can also check the settings menu — iOS devices say "iOS" or "iPadOS" in the About section. Android devices say "Android" in the About section.

Can I use a tablet for work?

Yes, many people use tablets for work — email, spreadsheets, presentations, note-taking, and document editing. Tablets work best for tasks that do not require a lot of typing. If your work requires typing long documents or using software that only runs on Windows or macOS, a laptop may be more practical.
