3. ANSI vs ISO Keyboard: Understanding the Key Differences

ANSI vs ISO Keyboard

When choosing a keyboard, it’s essential to grasp the distinctions between ANSI (American National Standards Institute) and ISO (International Organization for Standardization) layouts. These two layouts are the most prevalent globally, each with its unique features.

The primary discrepancy lies in the physical size and arrangement of keys. ANSI, prevalent in North America, features a smaller Enter key and differently shaped Left Shift key than the ISO layout used in Europe and other regions. Additionally, the ANSI layout includes a larger Backspace key and a differently positioned | key.

Understanding these differences is crucial for individuals who switch between keyboard layouts or work in multinational environments. By recognizing the nuances, users can select the layout that best suits their needs, optimizing their typing experience. Whether choosing an ANSI or ISO keyboard, it’s vital to consider specific preferences and requirements.

3.1 Comprehending ANSI vs ISO Layout

ANSI and ISO, major keyboard layouts, differ in the size and placement of specific keys. These physical layouts shape the keyboard’s form and key positions, distinct from logical layouts like QWERTY or Dvorak, determining key mappings.

3.2 Key Differences Between ANSI and ISO Layouts

The main differences include:

  • Enter key: ANSI has a wide rectangular key, while ISO features an upside-down L-shaped key over two rows.
  • Left Shift key: ANSI has a full-length left shift key, while ISO’s is smaller to accommodate additional keys.
  • Backslash key: ISO’s layout has a smaller and differently positioned backslash key.
  • Right Alt key: ANSI has Alt keys on both sides, while ISO replaces the right Alt with Alt Gr.
  • Total keys: ISO keyboards have 105/88 keys vs ANSI’s 104/87.

3.3 Advantages and Disadvantages of ANSI Layout


  • Wider, easier-to-press Enter key placed closer to the right side.
  • Identical size for left and right Shift keys.
  • Enhanced accessibility for alternate key functions.


  • Difficulty in typing certain non-English characters and diacritics.
  • Non-standardized for non-US keyboards.

3.4 Advantages and Disadvantages of ISO Layout


  • Extra key allows access to special characters and diacritics.
  • Accommodates a wider range of languages, common in European and non-US keyboards.


  • Smaller left Shift key can lead to miskeys.
  • Less ergonomic Enter key placement for some users.
