Informatec Digital » Resources » PC keyboard reviews: a complete guide to choosing the right one

Choose a PC keyboard It's no longer a matter of going to the store, randomly trying out two models, and buying the cheapest one. Today, mechanical, membrane, optical, magnetic, ergonomic, compact, wireless, and even fully customizable keyboards coexist, each designed for a very specific type of user.

If you write for hoursWhether you play competitive games, work in a shared office, or are looking for something simple for an elderly person, you'll want to learn more. How a keyboard works inside, what types there are, and what advantages each one offers.In this guide, we've gathered all that information in an organized way, with examples of formats, switch technologies, ergonomics, sizes, brands, and representative models so you can make the right choice for your next purchase.

What does a keyboard actually do and how does it work inside?

A PC keyboard is the most used input peripheral of the computerEach time you press a key, a signal is generated that a small internal microprocessor (the encoder) translates into a "scan code" which it sends to the operating system. This code is then converted into the letter you see on the screen, a shortcut, a multimedia command, or the illumination of the lock LEDs.

To detect each key, the keyboard uses a matrix of rows and columns printed on circuitsWhen you press a key, you close the circuit at a specific point on that grid. The encoder identifies which intersection has been activated and sends the corresponding code to the PC. Depending on the type of switch (mechanical, membrane, optical, Hall Effect, etc.), the way the circuit is closed, the force required, and the travel distance vary considerably.

The famous lights of Caps Lock, Num Lock or Scroll Lock The keyboard itself doesn't control them; the computer does. You press the key, the keyboard sends the code, and the system decides whether to turn the corresponding indicator on or off based on its internal state.

Main PC keyboard technologies

Before getting into specific sizes or models, it's important to be clear What types of keyboards exist according to their technologyThis affects noise, durability, price, typing accuracy, and long-term comfort.

On one hand we have keyboards of membrane and rubber dome, the typical cheap and silent onesOn the other hand, there are the classic mechanical keyboards, highly precise and customizable, as well as optical and magnetic options designed for advanced gaming. And of course, there are the low-profile, laptop-style (chiclet) keyboards, common in office environments and for users who prioritize portability.

Membrane and rubber dome keyboards

Membrane keyboards are based on three overlapping flexible layers: an upper layer with conductive tracks, an intermediate layer with holes, and a lower layer that is also conductive. Each key rests on a rubber dome which, when pressed down, passes through the intermediate hole and joins the two conductive layers, closing the circuit for that key.

In the most widespread design, the one of dome switch keyboardEach key rests on a rubber or silicone dome that collapses when pressed, bringing a point of graphite or conductive material to the membrane below. This is the solution you see in countless budget keyboards, office combos, and quiet home models.

Its main advantages are a Very low price, discreet operation and reduced weightIn addition, you can find splash-resistant models. However, the touch is less precise, the domes have a shorter lifespan, and they are not usually easy to disassemble. Clean thoroughly and it's more likely that some pulses won't fully reach the activation point.

Mechanical keyboards: the current benchmark

On a mechanical keyboard, each key has its own function. Individual switch consisting of housing, spring and stemThat switch defines the force required to press, the travel, whether there is a tactile bump, whether there is a loud click or whether the press is completely linear and silent.

Compared to membrane keyboards, mechanical keyboards stand out for their accuracy, responsiveness and durabilityThey can easily withstand over 50 million keystrokes per key. Furthermore, they are much easier to clean thoroughly and customizesince in many models you can change both the keycaps and the switches themselves (if the PCB is hot-swappable).

The downside is that they tend to be more expensive, bulkier and noisierHowever, silent switches, internal damping foams, and low-profile designs have emerged that significantly soften the sound, allowing them to be used without problems in offices or shared environments if the switches are chosen well.

Optical and Hall Effect (magnetic) switches

In recent years, keyboards with optical or opto-mechanical switchesHere, activation doesn't depend on a metallic contact, but rather on the interruption of an infrared light beam within the switch itself. Since there are no parts that physically "bounce," the bounce time is almost eliminated, and extremely fast pulses can be recorded without loss.

The Hall Effect or magnetic switches They use a sensor and a magnet to measure the exact position of the key's stem. This allows you to configure, via software, the point at which the key is considered pressed. You can set it very close to the beginning of its travel for maximum speed or delay it to minimize accidental keystrokes, something highly valued in competitive gaming and in models with features like Rapid Trigger or Snap Tap.

Chiclet or low-profile laptop-type keyboards

When we talk about chiclet keyboards we are referring to the typical laptop flat, separated keysThese are mounted on scissor or butterfly mechanisms that, in turn, act on a diaphragm. The stroke is short, the profile very low, and the noise level quite reduced.

This type of keyboard is ideal if you prioritize portability, silence and a minimalist lookHowever, if you tend to pound the keys to the floor, you may notice finger fatigue over time. Some users, especially those who type a lot, end up preferring a good low-profile mechanical keyboard to combine speed and comfort.

Types of mechanical switches and typing feel

Within the mechanical world there are literally dozens of types of switchesBut they can all be categorized by how they feel when writing and by the effort/skill they require. Understanding this aspect well is key to avoiding regret after your purchase.

The classic classification distinguishes between linear, tactile, and clicky switches, with internal variations depending on the manufacturer (Cherry, Gateron, Kailh, Razer, Logitech, Keychron, Akko…) and depending on the intended use (intensive writing, gaming, mixed use or quiet environments).

Linear, tactile, and clicky

The linear switches They offer a smooth, seamless feel, with no intermediate bumps or audible clicks. They activate with the same resistance from start to finish, making them a favorite for competitive gaming where speed is more important than tactile feedback.

Switches tactile They include a small bump in the key travel that indicates the activation point. They don't always make extra noise, but you do feel that "tap" with your finger that lets you know the key has been registered. They are very popular for those who want a balance between typing and gaming.

The clicky They add a rather clear and distinct clicking sound to the pothole. They're reminiscent of old typewriters and are addictive for many writers, although they can be a nightmare for your office colleagues if they're not warned.

Examples of Cherry MX and derivatives

Cherry is the best-known historical manufacturer, and its Cherry MX family has become a benchmark. Many others (Outemu, Gateron, Kailh…) use those strength and travel values ​​as a starting point to offer compatible alternatives.

The Cherry MX Blue They are clicky, with a tactile bump and an audible click; they require around 50 cN to actuate and about 60 cN at the bump point. They are ideal for those who enjoy a constant click while typing, but not so much for those who prefer silence or very fast double-tapping.

The Cherry MX Brown They are touch-sensitive without a click, with a force of around 45 cN. They are considered an "all-rounder" standard because they are suitable for both comfortable typing and gaming without disturbing others too much.

The Cherry MX Red They are lightweight linear motors (also around 45 cN), designed for gaming due to its smoothness and low resistanceIn Speed ​​or Silver versions, they advance the actuation point to about 1,2 mm, something that many eSports players appreciate.

There are also harder variants such as the Cherry MX Black (about 60 cN), recommended if you tend to press your fingers firmly and want to avoid accidental presses, or the Cherry MX Silent, with internal rubber parts that significantly reduce the impact and return noise of the key.

Keycap profile and material

The key profile (OEM, Cherry, SA, DSA…) determines the height, curvature and inclination of each rowThe OEM and Cherry profiles are the most balanced for general use; SA is taller and has a retro look; DSA is flat and uniform. Here, tradition reigns supreme: there isn't one that's universally best.

As for materials, almost all the keycaps sound ABS or PBTABS is cheaper and tends to become shiny with use, while PBT withstands wear and tear and fingerprints better, maintaining a matte texture for longer.

It's easy to find this on mid-range and high-end keyboards. PBT Double-Shotwhere the legends are molded with two different plastics so they never fade. There are also laser-engraved or sublimated keys, much more durable than the simple screen printing or stickers on very cheap keyboards.

Distributions, sizes and shape factors

Besides the internal technology, the comfort of a keyboard depends heavily on its layout and its sizeA full-size office keyboard is not the same as a 60% keyboard designed for eSports or an ergonomic model split into two blocks.

Choosing the right format affects the space on the table, the position of your shoulders when using a mouse and keyboard, and how easy it will be for you to type. use shortcuts without lookingTherefore, it is advisable to review the ISO/ANSI standards and the most well-known percentages (100%, TKL, 75%, 65%, 60%, 96/98%).

ISO, ANSI and layouts by language

When we talk about layout We're referring to both the language and the physical key standard. In Spain, the norm is ISO-ES: a large, inverted L-shaped Enter key, an extra key next to the Z key, and, of course, Dedicated Ñ key and accents in familiar positions.

In the United States, ANSI-US is used, with a smaller, rectangular Enter key and some keys offset. Many gaming or custom keyboards are only sold this way; you can configure them in Spanish via software, but the printed legends will no longer match what you type, which can be annoying if you frequently check the keys.

Sizes: full size, TKL, 75%, 65%, 60%, 96/98%

The percentage nomenclature indicates the number of keys compared to a full keyboard or its approximate width. The most common formats are:

• Full size (100%)Classic keyboard with numeric keypad, function row, arrow keys and navigation keys (Insert, Delete, Page Up, etc.). It usually has around 104-105 keys.
• TKL (Tenkeyless, ~80-85%)The numeric keypad is removed, but everything else remains. It's very popular in gaming because brings the mouse closer to the body and leaves more room to move it.
• 75%Similar to a TKL keyboard but with more compact keys, often inspired by laptop layouts. It retains arrow keys and function keys, but reduces gaps and intermediate columns.
• 65%: It retains arrow keys and a few extra keys (Del, PgUp, PgDn), but sacrifices the physical F1-F12 row, accessing it with the Fn key.
• 60%: ultra-compact format that only includes the alphanumeric block. Arrow keys, navigation, and functions are used using Fn combinationsIdeal if you want maximum free space for the mouse.
• 96 / 98%These are very compact keyboards that retain the numeric keypad but narrow the central area to reduce the overall width. They are a good middle ground if you need many keys without sacrificing a clutter-free desk.

Nor should we forget the split keyboardswhere each hand has its own separate block to improve ergonomics, nor the special one-handed models geared towards macros or gaming.

Connectivity, lighting and extras that make a difference

Beyond the keys, a good PC keyboard review needs to look at how they connect, what their lighting is like, and what extra features they offer: macros, volume wheels, customization software, liquid resistance, etc.

Choosing between wired or wireless, RGB or white backlighting, a simple keyboard or one with an OLED display and dedicated dials can greatly change your daily experience, especially if you work and play with the same equipment.

Wired vs. Wireless

Wired keyboards, usually USB, offer minimal latency, zero battery dependence, and they tend to be somewhat cheaperThey are the safe bet for gaming setups where you're looking for maximum reliability or for fixed workstations where cabling isn't a problem.

Wireless models can use Bluetooth, 2,4 GHz USB receivers, or bothIn exchange for charging the battery or changing batteries every so often, you gain in visual clarity, portability, and the possibility of connect them to multiple devices (PC, laptop, tablet, Smart TV…) with just the push of a button.

Lighting and visual ergonomics

Backlighting isn't just for aesthetics. In dimly lit environments, it helps to Identify the keys without straining your eyesAnd on advanced keyboards, it allows you to assign colors to specific areas (WASD, editing keys, macros…) or synchronize RGB effects with games and other peripherals.

However, in wireless models it's worth remembering that Lighting is one of the elements that consumes the most battery power.That's why many keyboards incorporate proximity or ambient light sensors that adjust the brightness according to the situation or turn off the keys when they don't detect hands nearby.

Macros, dials, hot-swap and other advanced features

In the mid-to-high range, it is becoming increasingly common to find keyboards with programmable macro keysVolume wheels, dedicated multimedia buttons, and multifunction dials. These controls allow you to, for example, change the brightness, skip tracks, or control an editing application without taking your hand off the keyboard.

Another key aspect of the enthusiast range is the possibility of replace switches without soldering (hot-swappable)With a simple extractor you can remove a faulty switch or test different sensations on the same board, without having to resort to soldering tools.

Many models incorporate internal memory for saving complete lighting profiles, macros, and key configurationso you can take your keyboard to another PC and maintain your environment without installing anything else.

Ghosting, N-Key Rollover and simultaneous key registration

If you've played with very cheap keyboards, you may have experienced the typical moment when you press several keys at once and the keyboard It doesn't register any keystrokes or "invents" another keyThis is called ghosting, and manufacturers combat it with different levels of rollover.

A keyboard with N-Key Rollover (NKRO) It's capable of registering all the keys you press simultaneously without errors. Many gaming models indicate 6KRO, 10KRO, or full NKRO. If you frequently hold down multiple letters, spaces, and modifiers at the same time (very common in shooters, fighting games, or music titles), you should check this specification.

Ergonomics, health, and keyboards for seniors

Beyond the specifications, we mustn't forget the human element: a poorly chosen keyboard can end up in wrist pain, heavy shoulders, or tired fingers If you spend many hours using it. And in the case of older people, readability and simplicity are almost as important as the internal technology.

The good news is that today there are ergonomic split keyboards, curved models, options with generous wrist rests, and specific designs with large keys and high-contrast letters designed for those with vision or dexterity problems.

Ergonomic keyboards and hand posture

Ergonomic keyboards have been developed for reduce repetitive strain injuries such as carpal tunnel syndrome. They usually divide the alphanumeric area into two blocks slightly rotated and raised towards the center, so that the hands fall in a more natural position.

Many include padded wrist rests, multiple tilt positions, and wavy or "split" designsCombined with a suitable chair and a good table height, they help keep your back straight, your elbows relaxed, and your wrists in a neutral position, which is appreciated in the long run if you write or program for hours.

Options designed for older people

When the keyboard is going to be used by an elderly person, it is advisable to prioritize very specific features: Large, well-spaced keys, clear, high-contrast typography (for example, large white letters on a black background) and quiet operation that is not annoying.

It's also a good idea to choose simple models, without dozens of extra keys that could cause confusion, and consider soft backlighting if you often use your computer in dimly lit rooms. In those cases, a quiet membrane keyboard or a low-profile chiclet is more advisable than a clicky mechanical keyboard full of RGB lights.

Multilingual keyboards and alternative layouts (QWERTY, Dvorak…)

Modern operating systems (Windows, macOS, Linux, Android, etc.) allow Change the keyboard layout via software without modifying the physical keyboard. That means you can use an English ANSI keyboard in a Spanish layout, or an alternative layout like Dvorak or Colemak if you feel like experimenting.

For non-Latin languages ​​(Arabic, Cyrillic, Thai, Japanese, etc.), physical keyboards often come with specific keycaps and require specific drivers or layouts for each key to print the correct symbol. This is important to keep in mind if you buy an imported keyboard.

The omnipresent QWERTY It originated in the late 19th century to prevent mechanical typewriters from jamming, by separating letters that were often used consecutively. Today, that limitation no longer exists, but the layout has survived out of habit and because switching to another requires relearning.

El Dvorak keyboardPatented in 1936, this layout rearranges the letters so that most keystrokes occur on the home row, distributing the pressure more evenly between both hands. Its proponents claim it allows for faster and less strenuous typing, but its adoption remains limited because the entire keyboard ecosystem, including the physical key labels, is designed with QWERTY in mind.

Custom keyboards and extreme customization

Within the enthusiast community, the so-called custom or personalized keyboardsInstead of buying a factory-assembled model, the user chooses each component: case, board, PCB, switches, stabilizers, keycaps, cable, and even the type of internal mounting.

The usual approach is to start from barebone kit It comes with a chassis, PCB, and circuit board, allowing you to add your own switches and keycaps. The main goal is to achieve a very specific feel and sound: from extremely quiet keyboards designed for office use to "thocky" configurations with a deep, powerful sound that appeals to many enthusiasts.

Almost all of these keyboards use firmware QMK or VIAwhich allow you to completely reprogram key assignments, create layers of functions, and adjust macros and lighting without relying on proprietary manufacturer software.

Membrane keyboards versus mechanical keyboards: which is more worthwhile

With all this information on the table, the eternal question remains whether it's worth making the leap to a mechanical keyboard or if a good membrane model is sufficient for your intended use.

If you prioritize Low price, silent operation, and you don't need ultra-precise touch.A decent membrane or rubber dome keyboard can be perfectly adequate, especially for office work, web browsing, and light use. There are options with backlighting, spill resistance, and multimedia keys that more than meet the needs of the average user.

If, on the other hand, you spend many hours writing, program daily, or play games intensively, you'll easily notice the difference when using a well-chosen mechanical keyboardThe feel, speed, and consistency of the keystroke, along with the ability to customize and replace parts, usually justify the higher price for this type of user.

What to consider when buying a PC keyboard

To wrap up this PC keyboard review, let's summarize the key criteria you should consider before making a purchase. It's not about memorizing an endless list, but rather understanding a few basic points.

• Primary useIt's not the same to write eight hours a day, play competitive games, edit video, or use the PC sporadically.
• FormatDo you need a numeric keypad or can you live without one? Will a full-size laptop fit on your desk or is a TKL/75% laptop better?
• Switch type: linear (fast and smooth) for gaming, tactile if you want a well-defined activation point, clicky if you love the sound and don't bother anyone.
• Noise: key if you share a room, work in an office, or record audio near the keyboard.
• Connectivity: wired for total reliability, wireless if you value clean space and multipoint connection.
• ErgonomicsWrist rest, tilt, key profile and layout greatly influence comfort at several hours of viewing.
• Extras: macros, RGB, volume wheels, OLED display, hot-swap, liquid resistance or configuration software.
• BudgetYou can find very decent keyboards for little money, but premium models, especially custom ones, quickly increase in price.

Taking the time to consider these aspects, even trying out different switches in-store if you have the chance, often makes the difference between ending up with a keyboard that drives you crazy or a peripheral that It becomes your trusted tool for years to come.By understanding technologies, layouts, sizes, and customization options, you have everything in your favor to make the right choice and enjoy every press.
