Different 100% Keyboard Layouts & Number of Keys

As we mentioned above, how many keys in a full-size keyboard depends on keyboard layouts including ANSI, ISO, and JIS. Let's break down the details of each layout!

  • Complete key layout: 100% keyboard provides all standard keys, offering a versatile input option for various tasks.

  • Comfortable typing experience: The spacious layout and distinct key clusters create a roomier feel, reducing the likelihood of accidental keystrokes.
  • Maximum versatility: While any keyboard size can support macro mapping, full-size keyboards offer the most space for programming single keystrokes to execute multiple inputs.

While it has become a popular choice for long, full-size keyboards come with their downsides.

  • Space requirements: The larger size of 100% keyboards demands more desk space, posing a challenge in smaller work areas.
  • Heavyweight: Due to their bigger size and additional features, full-size keyboards can be heavier than smaller options.
  • Less portability: The bulkier form factor makes full-size keyboards less portable and occupies more packing space compared to more compact alternatives.
  • High cost: Full-size keyboards, especially those with additional features, can be more expensive than compact keyboards with fewer keys. You should consider carefully when creating a custom 100% keyboard since every key cap and trigger adds extra expenses.
  • Not suitable for small hands: A larger keyboard means you have to move your hands and fingers more to perform your tasks. Users with smaller hands may find the larger size and key spacing less comfortable.
  • Limited ergonomics: While some full-size keyboards come with ergonomic features, their big size may limit customization for individual ergonomic needs.
  • Unused features: Let's be honest! Having media controls on a keyboard doesn't necessarily guarantee their frequent use. Extra features may hold little significance or value to individual users.

Full-size keyboards are versatile and can cater to a wide range of users, including gamers, typists, programmers, and casual users as they offer all the keys you need for any task.

Gaming keyboards often take cues from the full-size design thanks to extra goodies like media keys and macros. Even so, full-size keyboards are still a hit with all sorts of users. Whether you're a gamer, a writer, a coder, or just someone who likes a good ol' reliable keyboard, the full-size model has you covered. So, no matter what you're up to, you can count on a full-size keyboard to have your back.

Just a quick heads-up: While its spacious design and ergonomic support can enhance productivity, be mindful of its tendency to take up space on your desk, which could potentially make typing feel a bit cramped.

Factors to Consider when Choosing a Keyboard Size

Before we get into the nitty-gritty, let's talk about what you should consider when choosing the perfect keyboard size for you!


If you find yourself typing for long periods, it's crucial to choose a keyboard size that supports a comfortable hand and wrist position.

You can look into full-size keyboards with split layouts or ergonomic designs. They might feel a bit weird at first, but they're kinder to your hands. Some even come with wristrests and adjustable heights for extra comfort.

Nonetheless, if you have smaller hands, go for more compact options to minimize movement and fatigue for your hands and fingers. No need to search far and wide! We've compiled a roundup of the best keyboards tailored for smaller hands. Let's take a peek!

Desk Space

Size matters! Measure your available desk space precisely to avoid overcrowding. Got a roomy desk? Go for the full-size keyboard! It's comfortable and won't hog your space.  On the flip side, if you’re working with limited space or prefer a minimalist setup, opt for a compact keyboard like a Tenkeyless (TKL) or 60% model. These smaller keyboards will help maintain a tidy desk and can enhance your workspace aesthetics.

Full-size keyboards are not as portable as their more compact counterparts as they are bulky and may not be as convenient to carry around. If you are often on the move, you may find that compact or travel-sized keyboards are more suitable for your needs, fitting easily into bags and offering a lightweight solution.

Always customize the keyboard size based on your specific use. Whether for work, gaming, or general typing, identifying your main purpose will help you narrow the options.

For example, if you type extensively for work or writing, go for the full-size keyboard with all the perks. Besides, consider keyboards with specific features such as customizable shortcuts and media keys for tasks like programming, or graphic design. For frequent travelers, a compact and lightweight keyboard is ideal for on-the-go use.

Keyboards come in different price ranges, from affordable to high-end. Budget-friendly ones like Aukey's click-clacks (under $60) suffice for basic typing but may lack advanced features.

To unlock more keyboard goodness, expect to pay more for extra features and premium materials like aluminum frames. You can check out Roccat Vulcan II and Keychron Q6, priced at over $200, delivering a top-notch typing experience.

Generally, full-size keyboards often cost more than compact ones due to extra keys and features. Yet, variations among products and brands can affect costs. Furthermore, more specialized sizes are often even more expensive due to lower production volume.

It’s wise to carefully consider your typing requirements and weigh the costs and benefits before purchasing.
