What Is a Full Size Keyboard?

If you’ve ever searched for a mechanical keyboard or browsed gaming setups online, you’ve probably seen the term full size keyboard—also known as a 100% keyboard. But what exactly does “full size” mean? Why do some people insist on using it, even when smaller layouts like 75%, 65%, and TKL have become increasingly popular?

This complete guide will explain what a full size keyboard is, what makes it unique, why it remains an essential choice for many users, and how it compares to smaller layouts.

What Is a Full Size Keyboard?

A full size keyboard is a keyboard layout that includes all standard keys found on a traditional desktop keyboard. This layout typically contains 104 keys (ANSI) and features:

  • Main alphanumeric typing area
  • Full function row (F1–F12)
  • Dedicated arrow keys
  • Navigation cluster (Home, End, Page Up, Page Down, Insert, Delete)
  • Number pad
  • Modifier keys (Ctrl, Alt, Shift)
  • System keys (Print Screen, Scroll Lock, Pause)

In other words, a full size keyboard provides the complete, uncompromised layout used in offices, gaming setups, and productivity-heavy environments for decades.

The Key Components of a Full Size Keyboard

A full size keyboard contains several distinct clusters. Understanding these helps explain why it’s so versatile:

1. Main Typing Area

This is the central part where you type letters, numbers, and punctuation. Its layout is standardized (QWERTY, AZERTY, etc.).

2. Function Row (F1–F12)

Located at the top, the function row is widely used for:

  • Shortcuts (brightness, volume, media controls)
  • Software commands (F5 refresh, F2 rename, F12 developer tools)
  • Gaming macros

3. Navigation Cluster

These keys help with text editing, data navigation, and productivity tasks:

  • Home
  • End
  • Insert
  • Delete
  • Page Up
  • Page Down

Editing documents or spreadsheets becomes significantly faster with these dedicated keys.

4. Arrow Keys

Always placed separately for easy tactile access. Gamers and writers both rely heavily on them.

5. Number Pad (Numpad)

This is what truly distinguishes a full size keyboard from smaller layouts.

It offers:

  • Rapid numeric entry
  • Calculator-style input
  • Shortcuts used in Excel, finance, CAD, accounting, and gaming

For many professional users, losing the numpad is not an option.

How Many Keys Does a Full Size Keyboard Have?

Most full size keyboards use the 104-key ANSI layout, which is standard in North America.

However, other regions use:

  • 105 keys (ISO)
  • 108–109 keys (JIS)

The core idea remains the same:

A full size keyboard includes every key without shortcuts, layers, or omissions. Check more about How Many Keys Does a Full Size Keyboard Have?

Why Do People Still Prefer Full Size Keyboards?

Even though smaller layouts are more compact and trendy, full size keyboards are still extremely popular—and for good reason.

1. Maximum Productivity

Professionals who work with numbers, spreadsheets, or documents need.

  • A dedicated numpad
  • Navigation keys
  • Function keys

This layout significantly improves speed and reduces repetitive strain.

2. Better Gaming Versatility

While some gamers prefer TKL keyboard (more mouse space), many choose full size because:

  • Some games use the numpad for commands
  • MMO and simulation games benefit from more physical keybinds
  • The spacing feels familiar and comfortable

With the rise of 8K polling rate full-size keyboards (like the Dareu A104X or A104 Master), gamers no longer need to sacrifice performance for layout size.

3. Zero Learning Curve

Full size is the “standard” layout many of us grew up with.

Switching to it requires no adaptation, unlike 60% or 75% layouts where:

  • Arrow keys may be hidden
  • Function keys require layers
  • Navigation keys are missing

4. Better Ergonomics for Some Users

For users with larger hands or those who prefer a spacious layout, full size keyboards provide a comfortable typing experience.

Full Size Keyboard vs. Other Keyboard Sizes

To understand full size keyboards better, it helps to compare them with smaller layouts:

  • Full size keyboard = most complete and accessible layout of them all
  • 98-key keyboard = almost full size, but more compact
  • TKL keyboard & 75% keyboard = strong middle ground between space saving and functionality
  • Small size keyboard = best for portability and minimal setups, but rely on layers

For users who prioritize productivity, shortcuts, and a numpad, a full size keyboard remains the most complete and accessible layout of them all. Want to check the details of the keyboard comparison? Click here.

Who Should Use a Full Size Keyboard?

A full size keyboard is ideal for:

  • Office workers
  • Programmers
  • Accountants
  • Data analysts
  • Gamers
  • Creatives who rely on shortcuts (Photoshop, Premiere, Blender)
  • Users with large desks
  • Anyone who prefers traditional typing comfort

If your workflow includes numbers, editing, shortcuts, macros, or heavy typing, a full size keyboard will make your life easier.

Modern Full Size Mechanical Keyboards

Modern full size keyboards—not just old office boards—come with advanced features such as:

  • RGB lighting
  • Hot-swappable switches
  • Tri-mode wireless (Bluetooth + 2.4G + Wired)
  • Gasket mount construction
  • Programmable knobs
  • Built-in TFT displays
  • PBT keycaps
  • 8,000 Hz polling rate (on gaming models)

For example, keyboards like the Dareu A104 Pro, A104X, and A104 Master combine full size layouts with modern ergonomic and performance-driven features.

This means today’s full size keyboards are not just practical—they’re powerful, customizable, and visually impressive.

Final Thoughts: Is a Full Size Keyboard Right for You?

A full size keyboard provides the most complete keyboard experience with no compromises. It includes all keys—letters, functions, arrow keys, navigation controls, and a full numpad—making it a top choice for professionals, gamers, and anyone who wants maximum efficiency.

Whether you need full-featured productivity tools, fast gaming performance, or a familiar typing experience, a full size keyboard remains one of the best and most versatile options.
