ANSI vs ISO Keyboard Layout: Which Is on Your Laptop?

What the two layouts look like

The keyboard of a laptop has a physical arrangement of keys that follows one of two standards: ANSI or ISO. ANSI stands for the American National Standards Institute, ISO for the International Organization for Standardization. These standards specify, among other things, the shape and position of the Enter key, the size of the left Shift key, and the total number of keys.

On an ANSI layout the Enter key is a wide horizontal rectangle, the left Shift key is long, and the backslash key sits above the Enter key. On an ISO layout the Enter key is an inverted L shape that spans two rows, the left Shift key is short, and an extra key sits between the left Shift and the Z row. That extra key is what makes an ISO keyboard have one more key than an ANSI keyboard.

As an example of the difference in key count, one laptop maker lists its keyboard as 78 keys in the ANSI version and 79 keys in the ISO version. The extra key in the ISO layout is the one next to the left Shift key.

If you are buying a laptop in the United States, the keyboard is almost certainly ANSI. If you are buying in Europe, the keyboard is likely ISO. The layout follows the regional market the laptop is sold for, not the brand or the model family. When you compare business laptop reviews, the keyboard layout is one of the regional specifications to match.

How the layout affects the way you type

For someone who types fast without looking at the keys, the layout matters because muscle memory knows where the Enter key and the left Shift key are. A person who learned to touch type on an ANSI keyboard reaches for a wide horizontal Enter key. An ISO keyboard puts a taller, angled Enter key in that spot, and the left Shift key is shorter, which changes where the little finger lands.

The two layouts also place punctuation and special characters differently. The exact characters printed on the keys depend on the language of the keyboard, not just on the layout. A laptop sold in Germany with an ISO layout will have different labels on keys than a laptop sold in France with an ISO layout. A laptop sold in the United States with an ANSI layout will show a different set of symbols on the number row.

For office work, the practical question is whether the keys you use often, such as Enter, Shift, and the punctuation around them, are where you expect them. If you switch between a desktop keyboard and a laptop that use different layouts, your typing accuracy can suffer for a while.

If you have always worked on a certain layout, staying with that layout on a laptop avoids retraining your fingers. The choice is about continuity, not about one layout being better for office tasks. A 14-inch business laptop often has a compact keyboard, but the layout standard still applies.

What a laptop listing tells you about the layout

A laptop listing usually does not state "ANSI" or "ISO" in the specifications. It will state the language of the keyboard, for example "English keyboard" or "German keyboard," and the region the laptop is sold for. A listing that says the keyboard has 78 keys points to ANSI, and one that says 79 keys points to ISO, but this level of detail is rare.

What you can check on a listing is the text that describes the country the laptop is intended for. A laptop sold through a North American distributor is ANSI with a US English layout. A laptop sold through a European distributor is ISO with a layout that matches the language of that country.

The model name and the product number can also help. Laptop makers often assign a suffix or a regional code to the model number that indicates the keyboard language. That code is a specification, not an opinion, so it is safe to match it to the keyboard you need. For a full list of specification checks, see the best business laptops for remote work.

If a listing is vague about the keyboard language, asking the seller a direct question is the right step: "Which keyboard language is installed?" and "Is this the US layout or the international layout?" are questions any buyer can ask before paying.

The rules of this site say nothing about one layout being better than the other for business work. The rule is simpler: get the layout you already type on, and confirm the language before you order.

Checking the layout before you buy

When you compare laptops on specifications, look for the line that states the keyboard. Some listings say "backlit keyboard," some say "spill-resistant keyboard," but few say "ANSI" or "ISO." The useful line on a listing is the one that names the keyboard language.

If the listing shows a photo of the keyboard, you can identify the layout yourself. A wide horizontal Enter key is ANSI. An inverted L Enter key that spans two rows is ISO. A long left Shift key with the backslash above the Enter key is ANSI. A short left Shift key with an extra key beside it is ISO.

For a small office that buys several laptops at once, it is worth ordering all of them with the same layout so that any employee can sit at any desk and type without re-learning the keys. Mixed layouts in one office create a small but real friction: people will hit the wrong key when they move between machines. The best business laptops for small office section keeps this in mind.

For a laptop that will stay on the desk with an external keyboard, the laptop layout matters less because most typing happens on the external keyboard. For a laptop that travels in a bag and is used on a train or at a cafe, the built-in layout is the one you type on, so the layout choice is more important. Travelers should review the best business laptops for travel before deciding.

For a person who types accents and special characters for work, the layout and the language of the keyboard are tied together. The right question is not just ANSI versus ISO, but whether the keyboard matches the language you write in.

How the layout relates to other keyboard choices

The layout is one part of the keyboard. Another part is whether the keyboard has a numeric keypad on the side, called a full keyboard, or omits it to keep the laptop smaller. A 14 inch laptop usually has a compact layout without a numeric keypad, while a 16 inch laptop may have room for one.

The backlight is a separate feature. A backlit keyboard helps in a dim room, but the backlight does not change the physical layout. The same keys, in the same positions, can be lit or unlit.

The key travel, which is how far a key moves when pressed, is a physical property that a listing may or may not state. It is separate from the layout. A short-travel keyboard and a long-travel keyboard can both be ANSI or both be ISO.

The layout is the geometry of the keyboard. Other features like the backlight, the numeric keypad, and the key travel are options that the layout does not determine. When you compare laptops, treat the layout as a fixed regional property and the other keyboard features as choices.

Some office workers connect an external keyboard to their laptop when at the desk. In that case the laptop keyboard layout matters only for the moments you type on the built-in keys, such as during travel or in a meeting room.

What to pick for your work

Questions

How can I tell if a laptop has an ANSI or ISO keyboard from the listing?

Look for the keyboard language in the specification. A US English keyboard is ANSI. A listing that says the keyboard has 78 keys is ANSI, and one that says 79 keys is ISO. If the listing shows a photo, a wide horizontal Enter key is ANSI, and an inverted L Enter key is ISO. For more guidance on reading a spec sheet, check the business laptop reviews.

Does the ANSI or ISO layout change which characters I can type?

The layout changes the shape and position of the Enter key and the left Shift key, and it changes the total number of keys. The characters printed on the keys are set by the language of the keyboard, which is a separate part of the specification.

Which layout should a business laptop have?

Neither layout is a business feature. A business laptop is defined on this site by Windows 11 Pro and a weight of 2.2kg or less. The keyboard layout follows the region the laptop is sold in and should match the layout you already type on.

Can I change the layout after I buy the laptop?

The physical layout is fixed. You can set the operating system to a different keyboard language in software, but the physical shape and position of the keys will not change. If you need the other layout, choose it before you order.

Is one layout better for typing speed?

The layout that you have trained on is the one you will type fastest on. ANSI and ISO are both standard layouts used by millions of typists. The difference is the position of the Enter key and the left Shift key, which is a matter of habit, not of quality.
