Keyboards vary in length based on their size. A full-size keyboard is about 17-18 inches, while compact options like TKL, 75%, 60%, and 40% range from 9 to 15 inches for space-saving designs.
Introduction
When choosing a keyboard, one common question is: How long is a keyboard? Keyboards come in different sizes, from compact models to full-sized versions, and their length depends on the number of keys and design. Whether you’re a gamer, office worker, or casual user, knowing the right keyboard size can improve comfort and efficiency.
A standard full-size keyboard is around 17-18 inches long, while smaller versions like tenkeyless (TKL) and compact keyboards range from 9 to 15 inches. This guide will explain the different keyboard sizes, their dimensions, and how to choose the right one for your needs.
Standard Keyboard Sizes and Their Lengths:
Keyboards come in different sizes based on the number of keys and their layout. Below are the most common types:
1. Full-Size Keyboard (100%)
- Length: Around 17-18 inches (43-46 cm)
- Keys: 104-108 keys
- Features: Includes a full number pad, function row, arrow keys, and navigation buttons.
- Best for: Office work, data entry, and gaming where all keys are needed.
A full-size keyboard is the largest standard option. It has all the essential keys and is ideal for users who frequently use the number pad. However, it takes up more desk space.
2. Tenkeyless (TKL) Keyboard (80%)
- Length: Around 14-15 inches (35-38 cm)
- Keys: 87-88 keys (no number pad)
- Features: Compact size while keeping function and arrow keys.
- Best for: Gamers and professionals who don’t need a number pad.
The TKL keyboard removes the number pad to save space while keeping all other keys intact. This makes it a popular choice among gamers and those who need extra desk space for a mouse.

3. 75% Keyboard
- Length: Around 12-13 inches (30-33 cm)
- Keys: 80-84 keys (compact with function row and arrow keys).
- Features: A slightly smaller layout with most essential keys close together.
- Best for: Those who want a compact yet functional keyboard.
A 75% keyboard keeps all important keys but arranges them more compactly. It’s great for users who need function keys and arrows but want to save space.
4. 60% Keyboard
- Length: Around 11 inches (28 cm)
- Keys: 61 keys (no function row, number pad, or dedicated arrow keys).
- Features: Lightweight and portable but requires key combinations for missing keys.
- Best for: Minimalist setups and those who travel often.
A 60% keyboard removes the function row and number pad, relying on shortcuts to access missing functions. It’s a favorite among gamers and typists who prefer a clean setup.
5. 40% Keyboard
- Length: Around 9 inches (23 cm)
- Keys: Around 40-45 keys (no function row, number pad, or navigation keys).
- Features: Requires heavy use of key combinations.
- Best for: Experienced users who prefer a custom layout.
The 40% keyboard is the smallest option and requires a lot of memorization for key combinations. It’s mostly used by keyboard enthusiasts who prefer ultra-compact designs.
Factors That Affect Keyboard Length:
Several factors influence the length of a keyboard, including:
1. Key Count and Layout
The more keys a keyboard has, the longer it will be. Full-size keyboards are longer than compact models.
2. Additional Features
Gaming keyboards with extra macro keys, multimedia buttons, or wrist rests are larger than standard keyboards.
3. Mechanical vs. Membrane Design
Mechanical keyboards often have thicker frames and keycaps, making them slightly larger than slim membrane keyboards.
4. Brand and Model
Different brands design keyboards with varying dimensions, even within the same key layout. Some compact keyboards have full-size keycaps, while others shrink key sizes to save space.
