Keyboards come in many shapes and sizes, but most follow standard layouts that evolved over years of use. The number of keys on a keyboard can give you an idea of its size, functionality, and intended use case.
Total Keys in a Keyboard
The total number of keys on a computer keyboard can vary depending on the type and layout of the keyboard. However, most standard keyboards consist of approximately 101 to 104 keys. These keys are divided into different categories, each serving a specific purpose.
Different Types of Keyboards
Now that we understand the basic sections of a keyboard, it’s important to note that there are different types of keyboards available in the market. The number of keys on a keyboard can vary depending on the type and purpose of the keyboard. Let’s explore some of the most common types:
1. Standard Keyboard
A standard keyboard, also known as a full-size keyboard, is the most widely used type of keyboard. It typically features 104 keys and includes all the sections mentioned earlier. These keyboards are suitable for general computing tasks and are commonly found in offices and homes.
2. Tenkeyless (TKL) Keyboard
As the name suggests, a tenkeyless keyboard is a standard keyboard without a numeric keypad. These keyboards are compact and save space on your desk. They usually have around 87 keys and are popular among gamers and users who don’t require frequent numerical input.
3. Compact Keyboard
Compact keyboards are even smaller than tenkeyless keyboards and often lack some of the function and navigation keys. These keyboards are designed for portability and are commonly used with laptops or in situations where space is limited. The number of keys on a compact keyboard can vary, but it typically ranges from 60 to 75 keys.
4. Gaming Keyboard
Keyboards crafted for gaming are tailored to meet the needs of gamers, often incorporating extra features and customizable options. These keyboards usually have more keys than standard keyboards, including dedicated macro keys, multimedia keys, and customizable RGB lighting. The number of keys on a gaming keyboard can vary depending on the model and brand.
5. Ergonomic Keyboard
Ergonomic keyboards are designed to provide a more comfortable typing experience, especially for individuals who spend long hours working on a computer. These keyboards feature a split or curved design, allowing users to position their hands and wrists in a more natural and ergonomic position. The number of keys on an ergonomic keyboard is similar to that of a standard keyboard.
6. Virtual Keyboard
In recent years, virtual keyboards have gained popularity, especially on touchscreen devices such as smartphones and tablets. These keyboards do not have physical keys but instead, display a virtual representation of a keyboard on the screen. The number of keys on a virtual keyboard varies depending on the device and the layout chosen.
Types of Keys in a Keyboard
1. Alphanumeric Keys
The keyboard primarily relies on alphanumeric keys, which are the most frequently utilized keys. They include both letters and numbers, allowing users to input alphanumeric characters. These keys are arranged in a QWERTY layout, which is the standard keyboard layout for most English-speaking countries.
2. Function Keys
The function keys, commonly designated as F1 through F12, can be found along the top row of the keyboard. These keys have different functions depending on the software or operating system you are using. They are commonly used for tasks such as opening help menus, adjusting screen brightness, and controlling media playback.
3. Modifier Keys
Modifier keys are special keys that modify the function of other keys when pressed in combination with them. The most common modifier keys are Shift, Ctrl (Control), and Alt (Alternate). These keys are essential for executing keyboard shortcuts and performing various commands.
4. Navigation Keys
Navigation keys are used for moving the cursor or caret within a document or text field. They include the arrow keys (Up, Down, Left, Right), Home, End, Page Up, and Page Down keys. These keys are particularly useful when editing documents or navigating through web pages.
5. Numeric Keypad
The numeric keypad, also known as the number pad, is a set of keys located on the right side of a standard keyboard. It consists of numbers from 0 to 9, mathematical operators (+, -, *, /), and other special characters. The numeric keypad is primarily used for quick numerical input and calculations.
6. Special Function Keys
Some keyboards may have additional special function keys, depending on their design and intended use. These keys can include multimedia keys for controlling audio and video playback, volume control keys, and shortcut keys for launching specific applications or performing specific actions.

1. Alphanumeric keys

3. Modifier keys (Shift, Ctrl, Alt)
4. Navigation keys (Arrow keys, Home, End, Page Up, Page Down)
