When choosing a keyboard, the organization of the keys is very important. By this we are not referring to the order of the keys, but to their disposal and that is that when manufacturing a keyboard there are two standards: ISO and ANSI. Each of them has its peculiarities and therefore differences with respect to the other standard. Which one is better to choose when buying a keyboard?
Many times you have observed how the way in which certain keys are placed on a keyboard, whatever the type, varies from one keyboard to another in the arrangement and size of certain keys. This was not something decided randomly, but it comes from two different standards that mark the way in which the keys are distributed on a keyboard. Both are totally valid and have been sharing space in the market for years, but they have certain differences between them.
ANSI Keyboards Features
ANSI is an acronym for the American National Standards Institute, which is a non-profit organization that oversees the development of standards for products, services, processes, and systems in the United States. ANSI’s job is not only to create standards for that country, but it also coordinates its standards at the national level with international ones. Therefore, the keyboards created under this standard will be designed to be used in that country and therefore will have a keyboard layout designed to write in English. For this reason, keys such as the “Ñ” typical of Spanish or “Ç” of languages such as Catalan or French are not integrated in this type of keyboard.
Before 1995, this type of keyboard had 101 keys in total, but the arrival of Windows 95 required the addition of the Windows keys and the context menu. Since then the configuration of its keys has not changed at all. Which at present is 104 keys in the complete models and 87 in the Tenkeyless configuration.
Regarding the specific specifications of ANSI keyboards, these are the following:
- The enter key is rectangular in shape.
- On ANSI keyboards the key is above the enter key and below the backspace key.
- The size of the Shift keys, on the left and right of the keyboard, is symmetrical on an ANSI keyboard
- It is easier to find replacement keys for an ANSI keyboard than an ISO keyboard.
Characteristics of ISO keyboards
It is very difficult that in markets where English is not the vernacular you will find an ANSI keyboard, in the rest of the world they use ISO keyboards. Where ISO refers to another non-profit organization in charge of maintaining standards in new products and services, with the difference that ISO has a totally international approach. So the keyboards are not designed for a specific language.
Because there are character differences between different languages, even in countries with the same alphanumeric encoding. Many of the unique characters of each language are shoehorn and these keys are difficult to access. The reason is that the space of each of the key lines is assigned by the standard, so it is necessary to juggle the space.
As for the differences with respect to the ANSI keyboard, these are the following:
- The enter key is shaped like an upside down inverted L.
- The left Shift key is 50% the size of the right.
- A new key is added, Alt Gr, which replaces the right Alt key with respect to an ANSI keyboard.
- It has one more key than ANSI keyboards, 105 in the case of a full keyboard and 88 keys in the case of a Tenkeyless keyboard.
- Finding spare parts for certain ISO standard keys is more difficult than ANSI if you want to build a totally custom keyboard.
ANSI or ISO, which keyboard is better for typing?
The most general function of a keyboard is to type text. And we cannot forget that in 95% the distribution of the keys is the same. The problem when going from an ANSI keyboard to an ISO type and vice versa comes with muscle memory when using certain keys, and it is that if there is something that we have developed over time, it is the ability to write with a concrete key configuration. It is possible that within the same standard we can find two types of size in terms of the keys and have a small adaptation time that lasts a few hours.
The move from ISO to ANSI or vice versa is different and requires more training. The difficulty is complicated if we are not going to write in English since all the keys are not complete. The problem with ISO keyboards is that they lose ergonomics compared to ANSI , but if you are used to typing on an ISO keyboard then the move to ANSI will cost you much more .
However, it is possible to get a fully reprogrammable ANSI keyboard and use it in any language with a Latin alphabet. Of course, you will have to get used to the new layout of the keys for this and it may take a while to get used to. We will drop this option to reprogram if you have bought an ANSI keyboard and need to configure it to Spanish.
And which keyboard configuration is better for gaming, ANSI or ISO?
Actually in what the most used keys in gaming are said there is not much difference between ANSI and ISO, the problem comes with the left Shift key that is smaller and less accessible on an ISO keyboard than on an ANSI one , which means that if you are playing a game that uses this key continuously then you will perform worse.
The problem comes when you have to replace certain keys due to wear, as we have said it is much easier to find parts for an ANSI keyboard than for an ISO keyboard, but this only applies to certain unique keys of ISO keyboards. Nor can we forget that there are gaming keyboards on the market, which are halfway between an ANSI keyboard and an ISO keyboard, with things like the shift keys having the same size.
