ANSI or ISO Keyboard on a Gaming Laptop: Which Layout Should You Pick?

What are ANSI and ISO layouts?

Keyboard layouts define the physical arrangement of keys. The two main standards are ANSI (American National Standards Institute) and ISO (International Organization for Standardization). They differ in the shape and position of a few keys, which affects how you type and reach for keys during play.

ANSI is the standard in the United States. It has a wide left Shift key, a horizontal Enter key (sometimes called Return), and a backslash key located above the Enter key. ISO is common in Europe and other regions. It has a smaller left Shift key, a tall, L-shaped Enter key, and an extra key next to the left Shift for the backslash or other characters. For a broader look at keyboard features on gaming laptops, see our keyboard features guide.

The difference in the Enter key shape is the most visible. On an ANSI keyboard, Enter is a single wide key. On an ISO keyboard, Enter is shaped like an inverted L, taking up two rows. This changes where your right pinky lands and how you press Enter.

• ANSI: wide left Shift, horizontal Enter, backslash above Enter.
• ISO: small left Shift, L-shaped Enter, extra key near left Shift.

How does the layout affect gaming?

For gaming, the layout matters most for keys you press frequently. The left Shift key is used for sprinting or crouching in many games. On an ANSI keyboard, the left Shift is wider, giving you a larger target to hit without looking. On an ISO keyboard, the left Shift is narrower, and there is an extra key next to it. This can lead to accidental presses if you are not used to it. If you are comparing keyboard types, also consider membrane versus mechanical switches.

The Enter key is less critical for gaming, but the shape affects how you reach it. The ISO L-shaped Enter can be easier to hit with your right pinky because it is taller, but some players find the horizontal ANSI Enter more natural. It comes down to personal preference and muscle memory.

The extra key on ISO layouts, often the backslash or a key with a different character, sits right next to the left Shift. If you are used to ANSI, you might press it by mistake when trying to hit Shift. If you are used to ISO, the ANSI layout might feel like the Shift key is too wide and the backslash is in an odd place.

Regional preferences and availability

The layout you are used to often depends on where you live. In the US, ANSI is the standard. In many European countries, ISO is common because it accommodates accented characters and the Euro symbol. Gaming laptops are sold with either layout depending on the region. If you care about RGB backlighting, note that the layout does not affect lighting customization.

If you buy a laptop from a US retailer, it will likely have an ANSI keyboard. If you buy from a European retailer, it may have an ISO keyboard. This is important if you are ordering online from another country, as the layout affects the physical keys and the printed characters.

Some manufacturers offer the same laptop model with different keyboard layouts for different regions. When you choose a gaming laptop, check the specifications to see which layout it has. The Apple MacBook Air, for example, lists its keyboard as having 78 (ANSI) or 79 (ISO) keys, showing that the layout is a specification you can verify.

Typing comfort and muscle memory

Your typing speed and accuracy depend on muscle memory. If you have used an ANSI keyboard for years, switching to ISO can slow you down and cause errors, especially with the left Shift and Enter keys. The same applies if you switch from ISO to ANSI. If you plan to replace the keyboard later, make sure you choose a replacement that matches your preferred layout.

For gaming, muscle memory is just as important. You do not want to look at the keyboard to find the Shift key during a match. Choose the layout you are already comfortable with, unless you are willing to spend time adapting.

If you are new to gaming laptops and have no strong preference, ANSI is often recommended because the larger left Shift is easier to hit, and the layout is more common in online guides and keycap sets. However, this is a general preference, not a rule. Some players prefer the ISO layout for its taller Enter key.

What to pick for your play

The best layout is the one you are used to. If you are buying a gaming laptop, check the keyboard layout in the specifications before you order. If you are in the US, ANSI is standard. If you are in Europe, ISO is common. If you are unsure, consider trying both in a store to see which feels more natural. You can also read our buying guide for gaming laptops to see which models offer your preferred layout.

For competitive play, the layout can affect your reaction time if you are not used to it. The left Shift key is crucial for many actions, so a layout that lets you hit it reliably is important. ANSI's wider Shift gives you more room, but ISO users can be just as fast with practice. If you play esports titles, check our esports gaming laptop picks for models with the layout you want.

Ultimately, the choice is personal. Do not let a layout preference override other important specs like the GPU, RAM, or screen refresh rate. A good gaming laptop with the wrong layout for you can be frustrating, but you can always use an external keyboard if needed.

Questions

Is ANSI better for gaming than ISO?

Many gamers prefer ANSI because the left Shift key is wider, making it easier to hit during play. However, it is not objectively better; it depends on your muscle memory and comfort. If you are used to ISO, switching to ANSI may cause errors. For more on keyboard choice, see our keyboard features guide.

Can I change the keyboard layout on a gaming laptop?

You can change the software layout in the operating system, but the physical keys remain the same. For example, you can set Windows to use a US layout on an ISO keyboard, but the key shapes and positions will not change. This can cause mismatches between what you press and what appears. If you need to replace the keyboard, check our replacement guide.

How do I know which layout a gaming laptop has?

Check the laptop's specifications. Manufacturers often list the keyboard layout, such as 'ANSI' or 'ISO'. The number of keys can also indicate the layout: ANSI keyboards typically have 104 keys, while ISO keyboards have 105. The Apple MacBook Air, for instance, lists 78 (ANSI) or 79 (ISO) keys.

Is it worth buying a laptop with a different layout to get better specs?

It depends on how much you value the layout. If you are a touch typist, a different layout can slow you down. If you are willing to adapt, you might find a better deal. However, for gaming, the layout can affect your performance, so it is often worth prioritizing your preferred layout. Consider the gaming laptop buying guide to balance specs and layout.
