ANSI vs ISO keyboard is one of those questions that only pops up once you’ve fallen deep enough into the world of mechanical keyboards to start noticing the finer details. At first glance, the difference might seem small, but it has a pretty big ripple effect—especially when it comes to keycaps.
If you’re upgrading your keyboard, like swapping out ABS keycaps for PBT ones, you’ll quickly realize that not all keycap sets are compatible with both layouts. This can turn a simple upgrade into a headache.
So, what’s the real difference between ANSI and ISO, and is one actually better? Let’s break it down.
What is an ANSI Keyboard Layout?

The ANSI Keyboard Layout is a widely used keyboard standard in the United States and Canada. ANSI stands for the American National Standards Institute, which sets various standards, including those for keyboards.
Features of the ANSI Layout:
- Enter Key: The Enter key is larger, and shaped like a horizontal rectangle.
- Left Shift Key: This key is longer compared to other layouts.
- Total Keys: A full-sized keyboard layout includes 104 keys.
An ANSI keyboard layout offers a straightforward design. It is popular due to its simplicity and ease of use. This layout is commonly found on many keyboards used for English typing environments.
What is an ISO Keyboard Layout?

The ISO keyboard layout is used mainly in European countries. "ISO" stands for the International Organization for Standardization. This layout has specific features that distinguish it from others.
Here are the key characteristics of the ISO layout:
-
Enter key:
- Shaped like an upside-down "L" instead of being wide and rectangular.
- Helps typists easily identify the unique structure of the layout.
-
Left Shift key:
- Smaller than on other layouts.
- Makes room for an extra key next to it, often used for special characters in different languages.
When it comes to the number of keys, an ISO keyboard has a total of 105 keys in its full-sized version. This makes it slightly different in design compared to ANSI keyboards, which include other common layouts.
Key Differences Between ANSI and ISO Keyboards
One of the most noticeable differences is the Enter key. On an ANSI keyboard, it's rectangular, making it easy to hit when typing quickly. In contrast, the ISO layout has an L-shaped Enter key, which some users find more ergonomic.
The Left Shift key is another key difference. On an ANSI keyboard, the Left Shift is longer. This can be helpful if you're used to typing with your pinky. The ISO keyboard has a shorter Left Shift, which might require some adjustment if you're switching layouts.
Additionally, the Backslash key placement varies. In the ANSI layout, it's located directly above the Enter key. For ISO, it is near the Left Shift. This can affect users who rely on frequent backslash use.
Lastly, ANSI typically has 104 keys in US models, while ISO features an additional key, making a total of 105 keys. This extra key might be valuable for multilingual typing needs.

Pros and Cons of ANSI vs ISO Keyboards
ANSI Keyboard Pros:
- More commonly available in the US.
- Larger left Shift key, which is advantageous for gaming.
- Frequently preferred for programming and fast typing.
ANSI Keyboard Cons:
- May not be as comfortable for European users.
- Lack of an additional key for extra symbols, which can be restrictive for non-English languages.
ISO Keyboard Pros:
- More suited to European typing habits due to the extra key.
- Contains the Alt Graph key which aids in typing special characters.
- Better for typing non-English languages that require additional symbols.
ISO Keyboard Cons:
- Less common outside of Europe, making them harder to find in some regions.
- Smaller left Shift key might be cramped for gaming.
Understanding these pros and cons helps in selecting a keyboard layout that suits your needs.
Which Layout is Best for You?
Choosing between the ANSI and ISO keyboard layouts depends on several factors including your location, typing habits, and specific needs.
For users in the United States and Canada, the ANSI layout is more common. It features a larger rectangular Enter key, which is easy to reach, and a wider left Shift key that many gamers find ideal.
In contrast, if you are in Europe or other regions where the ISO layout is prevalent, you might prefer its design due to familiarity.
Consider the following when selecting a layout:
-
Typing Habits: If you're accustomed to one layout, it might be more comfortable to stick with it.
-
Use Case: Programmers and general users often choose ANSI for its default compatibility and size of the keys.
-
Gaming: The larger Shift key on the ANSI layout can make gaming more convenient.
Ultimately, your choice will depend on what you find most comfortable and efficient for your use.
Conclusion
When choosing your layout, go with ANSI if you value simplicity or are already used to American keyboards. Opt for ISO if you type in multiple languages or find its structure more intuitive for your needs.
Ultimately, your choice should align with your personal preferences and typing habits to enhance your overall experience.

FAQs About ANSI vs ISO Keyboards
In this section, you'll learn about differences in key count between ISO and ANSI keyboards, their suitability for gaming, how to identify them, and whether switching layouts is possible.
Why does ISO have 105 keys and ANSI has 104?
ANSI keyboards usually have 104 keys, while ISO layouts typically have 105. The extra key on the ISO keyboard is near the Enter key. This setup affects keys like the left Shift and the Enter key, giving the ISO a different configuration which is common in Europe.
Is ANSI better for gaming?
Many gamers prefer the ANSI layout due to its larger left Shift key and easier access to certain keys. This arrangement can make gaming more comfortable and efficient. However, your personal preference and what you're used to might matter most.
How do I know if my keyboard is ANSI or ISO?
Check the Enter key shape on your keyboard. An L-shaped Enter key indicates an ISO layout, while a rectangular Enter key is a sign of an ANSI layout. The placement of other keys like the left Shift can also provide clues.
Can I switch between ANSI and ISO keyboards?
You can switch between ANSI and ISO keyboards, but it might take some adjustment. Key placement and feel might differ, which can impact your typing or gaming experience. Familiarity with one layout may require some adaptation to get used to the other.
Which is better ISO or ANSI keyboard?
There isn't a definitive answer to which is better; it depends on your needs and preferences. The ANSI layout is more common in the US, while the ISO layout is preferred in Europe. Consider your typing and ergonomic needs when choosing between them.
