ANSI vs ISO Keyboard: Which Is Better? 2022

When it comes to choosing between an ANSI vs ISO keyboard, there is no definitive answer as to which one is better. Both types of keyboards have their own strengths and weaknesses.

ANSI keyboards are usually more affordable, have a full-size layout and can fit into most computer cases.

On the other hand, ISO keyboards tend to be more expensive and have a slightly different layout than their ANSI counterparts, but they can provide a more comfortable typing experience due to their larger key sizes.

Ultimately, it’s up to you to decide which type of keyboard best suits your needs.

ISO Layout

The ISO standard keyboard was a layout for keyboards which is what the International Organization for Standardization created. It is extensively utilized in Europe, except in the Netherlands, where ANSI is the preferred layout.

ISO physical layouts come with 105 keys on full-size keyboards, keeping 87% of the components, unlike TKL, which has fewer components.

It is built on the QWERTY layout but with additional keys to make it easier for users to type in foreign languages. A variety of computer makers utilize the ISO standard layout for keyboards. It is also the layout that comes standard for several laptops and desktops.

The layout has a variety of keys not present on a standard QWERTY keyboard. This includes keys for accented characters and keys for typing in different languages. The layout also features essential functions like an option to change the keyboard’s layout, a key to open the character map, and an on-screen keyboard.

Its ISO keyboard layout can be perfect for those who are from abroad and need to be fluent in English. Let’s now look at the advantages of the ISO keyboard layout. The ISO layout is more suited to symbols than its ANSI layout. ANSI layout.

For instance, you could use the Dollar symbol “$” by using keys like the (Shift + 4) keys. You can also type the Pound symbol “EUR” using the (4+ Alt Gr) keys. (Alt Gr is the symbol for that the left Alt button)

Advantages of the ISO Layout

1. The Alt Graph Key

ISO layout is popular. ISO layout is well-known across Europe and elsewhere due to its inclusion of the Alt Graph (also known as AltGr) key. The key allows users to type characters with diacritics effortlessly. Diacritics are small symbols added to the letter to alter its sound—for instance, an acute.

The Alt Graph key gives access to the fourth and third variants when a character contains more than two diacritics. Without the Alt Graph key, it is possible to use these symbols. However, a more complicated solution can affect your typing speed. One option is to remap your keys.

2. A Closer Backslash Key

The backslash key is right to the left of the enter key. It’s easier to access. This can be particularly beneficial for software developers and others who need access to this key more often than normal. But, the backslash keyboard is only commonly used in programming.

Disadvantages of the ISO Layout

Disadvantages of the ISO Layout

1. The Enter Key Is Further Away

The enter key is farther away from an ISO layout due to it being reduced to include that backslash. This can be a big issue in terms of ergonomics because it’s a frequently used key.

This is an advantage of the ANSI layout, as when used regularly, it is more often utilized than the backslash keys. For most users having the ability to hit the enter key is far more critical than the key for backslash.

2. Far Away Left Shift Key

The left-hand shift can be reduced in an ISO layout to allow the backslash or greater/fewer keys to be added. In general, the left shift is more often utilized than a backslash or greater/fewer keys, and the reduction of the left shift key is not good also for ergonomics.

3. Cost and Availability

Since ISO layout keyboards are less well-known than ANSI models, these keyboards may be challenging to find. This means ISO keyboards tend to be more expensive and have fewer choices. The process of finding ISO keycap sets may be a challenge.

ANSI Keyboard

The ANSI Standard keyboard can be described as a computer keyboard that uses an ANSI Standard layout. This ANSI layout was created by IBM and later adopted as an industry standard US layout built on the QWERTY layout.

in 1995 Microsoft changed its keys by adding new keys, such as Ctrl and Alt, Windows key, and the other keys remained the same.

ANSI standard keyboards have 101 keys (pre-1995) and 104 full-size keys, including punctuation, alphanumeric, and function keys.

Function keys are situated on the top column of the keyboard. They are used to perform specific functions. The alphanumeric keys are in the keyboard’s middle row and can be used to type numbers and letters. The punctuation keys are situated in the lower row. They are used to write punctuation marks.

ANSI keyboards are extensively employed in the United States because it is simple to master and easy to use. The ANSI standard keyboard has a regular size and form, making it simple to locate and operate the keys. ANSI keyboard is also rugged and designed to stand up to daily usage demands.

However the ANSI keyboard does have some limitations: unlike its ISO keyboard, which includes an additional key and a spare key, the ANSI layout does not include an additional key that allows the user to add a second key that could be a different type of language or an extra symbol.

It is possible to purchase an ANSI keyboard layout and then reprogram it to accept the keys needed to type in your preferred language.

Additionally, if you often utilize the backslash key in your keyboard, then using this ANSI keyboard layout can take time and effort. Unlike ISO, this is because the backslash key is situated just above the key to enter and requires users to stretch farther to get it. ISO key layout.

The importance of layouts for keyboards.

The layout of your keyboard matters because it can affect performance, comfort, and overall health. If you’re not happy using the ANSI and the ISO layout, it is advisable to look into alternative keyboard layouts. You might be surprised by how easy and fast typing is with the different layouts.

ANSI vs ISO keyboard layouts: Key Differences

ANSI vs ISO keyboard layouts: Key Differences

1. Enter Key

In the ANSI layout, the key for entering is rectangular and wide, while in the ISO layout, the enter key is taller and more prominent and is shaped in an upside-down L-shape.

2. Left Shift Key

When using an ANSI keyboard on ANSI keyboard, the right and left shift keys are of identical size that is long and rectangular. In the ISO layout, it is the case that left shift keys measure approximately 50% of the left shift key’s size (approximately precisely the same size as the Ctrl left vital).

3. Backslash Key

If you’re using the ANSI layout the backslash button is just ahead of the key for entering and is precisely the identical size to the left Ctrl key. If you’re using the ISO keyboard, this is just to the right of the Enter key.

4. Right Alt Key

It is important to note that the right Alt key and the left Alt key are the same in the ANSI keyboard. When using an ISO keyboard left Alt key will be replaced with an Alt Graph key.

5. The Number of Keys

An ANSI keyboard features 104 keys that are full size and 87 keys that a compact size. The ISO keyboard is equipped with keys 105 that are full size and, more minor, 88 keys (one additional). Below is a picture of the layout of each of the ANSI, as well as ISO keyboards, in their compact (tenkeyless) arrangement.

ANSI & ISO Keyboard: Keycaps

There are two primary varieties of keyboard keycaps – ANSI and ISO. ANSI keys are the most commonly used within the United States, while ISO keycaps are more prevalent in Europe.

ANSI keycaps have a slightly different design than ISO keycaps, and the keys’ size is the most noticeable difference. Enter key. ANSI keys also feature a lip along the bottom; however, ISO keycaps don’t.

ISO keys are typically more durable than ANSI keycaps because they’re typically made of more robust, high-quality plastic. ISO keycaps typically have an easier texture and a more uniform color.

Which Keyboard Layout is Better: ANSI or ISO?

Which Keyboard Layout is Better: ANSI or ISO?

There is no answer to this question since it depends on individual preferences. Some would prefer the ANSI layout since it offers the traditional typing experience, while others prefer using the ISO layout, which offers a more accessible typing experience. Ultimately, it’s the user’s responsibility to decide which layout is the best for them.

Keyboard Physical Layout: What Matters the Most?

How we write could significantly impact our productivity overall. That’s why the keyboard’s physical layout is crucial. You can pick from different keyboard layouts, but they’re all different. Specific layouts are more suitable for particular needs. Some are better for specific tasks, while others are more general.

The most commonly used keyboard physical layouts include:

  • Dvorak
  • Colemak
  • Workman

QWERTY is among the well-known keyboard layout and is the one you’re currently using. It’s named in honor of the first six letters of the upper line of keyboards.

Dvorak is a lesser-known keyboard layout that is designed for ergonomic use. The letters are laid out to make using your wrists and hands easier.

Colemak is like Dvmechanorak It’s designed to be a less sluggish alternative. It maintains the QWERTY letter arrangement but shifts sure of the less popular lettering to the top row.

Workman is a different well-designed ergonomic layout for keyboards. It’s designed to reduce hand movements, which could help reduce fatigue.


1. What’s exactly the JIS layout?

JIS layout JIS design refers to the Japanese Standard layout used for their keys. The JIS layout utilizes the L-shaped upside-down Enter key, which splits the left shift into two keys. It also divides two keys for the backspace and adds three additional keys inside the spacebar space.

Overall, the JIS layout includes five additional keys compared to those in the ANSI layout, which is 109. The additional keys are necessary to support the Japanese input of characters.

2. Can I still use an ANSI keyboard even if my language uses an ISO layout?

You can utilize an ANSI keyboard that supports languages that require the addition of symbols and keys because of the ability to program mechanical keyboards.

The ANSI keyboard is more precise in the placement of its symbols and commonly used keys. To switch to other layouts, you can use Alt + shift and then hit the key with the symbol you want.

3. Where can I find places that sell ISO keycap sets?

An excellent source for ISO keycaps is CandyKeys. They sell a variety of different sets of keycaps in different colors. It’s not as impressive as the range of ANSI keycaps; however, it’s a good starting point.

The drop may also have ISO keycaps for group purchases. Currently, they do not have any currently available. However, they used to have these keys.

KBD Fans currently has 8 keycaps in a set that are compatible with keys that are compatible with the ISO layout. They also offer dye sublimated Cherry profiles, keycaps that are blank keycaps to fit the 65% and 60 percent keyboard, and extra keys are a cost if you purchase ANSI keycap kits, and replace the keys you want to replace.

4. Where can I find ANSI keycap sets?

ANSI keycaps are available all over the place. It is optional to enter ANSI to search for these keycaps. Simply looking for keycaps will show you the results you want as the default. Some good places to find keycaps are Kono, Candykeys, KBD Fans, and Mechanicalkeyboards.com.

5. Is ANSI or ISO better for gaming?

A majority of gamers use ANSI keyboards. Its left shift button is typically used to perform commands such as the crouching feature in first-person shooters and is easier to use in its larger size. Additionally, the broader range of keyboards available makes ANSI an excellent choice for changing your keyboard.
