If you've been shopping for a mechanical keyboard, you've definitely seen the term "Tenkeyless" or "TKL." You might have also seen keyboards described as "87-key." And then there's the whole percentage system: 100%, 80%, 75%, 60%. It's enough to make your head spin. So, what percent keyboard has 87 keys? The direct answer is an 87-key keyboard is an 80% keyboard. It's the sweet spot for countless typists and gamers, but the "why" behind that number and its classification is more interesting than you might think. Let's clear up the confusion.

What You'll Learn in This Guide

The Straight Answer: It's 80%

The percentage naming convention is a bit informal, but it's based on the key count relative to a standard full-size keyboard. A classic full-size keyboard, which includes the alphanumeric zone, function row, navigation cluster, and a dedicated number pad (numpad), typically has 104 keys in the US ANSI layout. Some have 105 or 108, but 104 is the baseline.

Take that 104-key board and remove the numpad. That's exactly 17 keys gone (the 10 number keys, Num Lock, /, *, -, +, Enter, and usually a 00 or . key). 104 minus 17 equals 87. In terms of percentage, you've removed about 16.3% of the keys, leaving roughly 83.7% of the original board. The community rounds this to 80%. It's not mathematically precise, but it's the universally accepted term.

This 80% layout has a proper name: Tenkeyless (TKL). "Tenkey" refers to the numpad (a set of ten number keys), so "tenkeyless" literally means "without the numpad."

Why Everyone Gets Confused About Keyboard Percentages

Here's where even seasoned keyboard enthusiasts trip up. The percentage system isn't an official standard. It's slang. Different brands and communities might use slightly different baselines. For instance, if your "full-size" reference point is a 108-key board (with extra media keys), an 87-key board is about 80.5% of that. The naming gets fuzzy.

The bigger confusion comes from layouts that sit between TKL and 60%. A 75% keyboard crams the navigation cluster and function row into a tighter space, usually ending up with 82-84 keys. A newcomer might see 84 keys and think, "That's close to 87, must be 80%." Nope. The 75% is a distinct, more compact category. The percentage refers to the footprint and layout density, not just a raw key count.

My own pet peeve? People calling a TKL a "90% keyboard" because it looks close to full-size. That's just wrong and muddies the waters. The 80% label, while imperfect, is the consistent term you'll find on retailer sites like MechanicalKeyboards.com or in discussions on r/MechanicalKeyboards.

87-Key vs. Other Keyboard Layouts

To really understand the 87-key TKL, you need to see it in context. Here’s how it stacks up against the competition.

Layout Name Approx. Key Count Percentage What's Included Best For
Full-Size 104-108 100% Everything: Alphas, F-row, Nav cluster, Numpad Data entry, accountants, those who need a numpad daily.
Tenkeyless (TKL) 87 80% Alphas, F-row, Nav cluster. No Numpad. Gamers, general typists, programmers, most desk setups.
75% 82-84 75% Alphas, condensed F-row and Nav cluster. No Numpad. Those wanting maximum compactness with dedicated arrow keys.
65% 66-68 65% Alphas, arrows, a few nav keys. No F-row, no Numpad. Portability fans who still need arrows.
60% 61 60% Just the alphas. Everything else is via layers. Minimalists, travelers, gamers who want mouse space.

Looking at this, the TKL's advantage is clear. It sacrifices only the numpad, a section many people don't use constantly. You keep the dedicated arrow keys, insert/delete/home cluster, and the function row—all immediately accessible without learning key combos. This is why it's often called the "no-compromise" compact layout.

The TKL Advantage in Action: A Gamer's Story

I switched from a full-size to a TKL about five years ago, and the difference wasn't subtle. My mousepad was no longer crammed against the side of the keyboard. I had a clear, open space to the right for sweeping mouse movements in FPS games. My posture improved because I could center the keyboard in front of me without the numpad pushing it to the left. For gaming, the TKL isn't just a minor space saver; it's an ergonomic upgrade.

Who Should (and Shouldn't) Use an 87-Key TKL Keyboard

The 80% layout isn't for everyone, despite its popularity. Let's break it down.

You're a perfect candidate for an 87-key keyboard if:

You play PC games. The extra mouse real estate is the number one benefit. Most games don't use the numpad for controls, so you're not losing functionality.

You have a small or cluttered desk. Shaving off 5-6 inches of width is a game-changer for dorm rooms, coffee shops, or just keeping your desk feeling open.

You're a programmer or writer who doesn't input long number strings. You use arrows and the nav cluster constantly for editing code or text. The F-row is handy for debug keys (F5, F11) or macros. The numpad? Maybe for the occasional bracket, but it's not critical.

You want a cleaner, more symmetrical aesthetic. TKLs just look balanced and purposeful on a desk setup.

You should probably avoid a TKL and stick with full-size if:

You work with spreadsheets, accounting software, or any data entry. The numpad is a massive efficiency tool for entering numbers. Using the top row is painfully slow in comparison.

You use the numpad for specific applications. Some CAD software, audio editing suites, or even older games bind heavily to the numpad. Check your workflow.

There's a hybrid solution, though: get a TKL and a separate USB numpad. You can place it on the left side (great for mouse-loving gamers) or stash it in a drawer and pull it out only when you need to crunch numbers. This modular approach gives you the best of both worlds.

How to Choose the Right 87-Key Keyboard for You

Okay, you're sold on the 87-key form factor. Now what? Here are the real decisions that matter, beyond just the key count.

Switch Type: This is personal. Clicky (Blue), tactile (Brown), or linear (Red). Don't just go by memes. If possible, order a switch tester or try keyboards at a store. For office use, maybe avoid the loud clickies. For gaming, many prefer fast, smooth linear switches.

Build Quality: A plastic case is fine, but a metal case (aluminum) adds heft, reduces flex, and just feels premium. It also affects the sound. Check if the keyboard has a steel plate inside—it makes typing feel more solid.

Keycaps: Most stock keycaps are ABS plastic, which can develop a shiny, greasy feel over time ("shine"). PBT plastic keycaps are more durable and textured. This is often the first upgrade people make.

Wired vs. Wireless: Modern wireless keyboards using Bluetooth or 2.4GHz dongles have minimal latency. A wireless TKL can dramatically clean up cable clutter. Just check battery life if it's not USB-C rechargeable.

Software & Programmability: Does it come with software to remap keys, create macros, or change RGB lighting? Some enthusiast boards use open-source firmware like QMK or VIA, which allow for deep, on-the-fly customization without any installed software—a huge plus for tinkerers.

My go-to recommendation for a first TKL? Something like the Keychron V3 or K8 Pro. They offer a fantastic entry point: solid build, hot-swappable switches (so you can change them later without soldering), PBT keycaps, and QMK/VIA support. You get enthusiast features without the enthusiast price tag.

Common Questions About 87-Key Keyboards

Is an 87-key keyboard good for programming?

For most programming, it's excellent. You retain the function row (useful for IDE shortcuts like debug/run), and the dedicated arrow keys and nav cluster (Home, End, PgUp, PgDn) are essential for navigating code. The only potential hiccup is if you frequently write mathematical or statistical code involving lots of numbers—then you might miss the numpad. Many programmers use a TKL and love the extra desk space.

What's the main disadvantage of a TKL for gaming?

Honestly, for most games, there isn't one. The disadvantage is for a very specific subset of gamers: those who play flight sims, space sims (like Star Citizen), or MMOs who have meticulously bound dozens of actions to the numpad keys. For them, losing that dedicated grid is a deal-breaker. For your average FPS, MOBA, or RPG player, the TKL is arguably superior because of the improved mouse space.

Can I still use an 87-key keyboard for data entry or accounting work?

You can, but you'll be handicapping yourself. The numpad is a speed and accuracy tool for numeric input. Using the number row across the top is significantly slower and more error-prone. If this is a core part of your job, stick with a full-size keyboard or get a TKL paired with a dedicated, high-quality numpad that you can position ergonomically.

How do I get used to not having a numpad?

The adjustment is quicker than you think. For numbers, you simply use the top row. For the secondary functions of the numpad (like the arrows on 2, 4, 6, 8), a TKL already has dedicated arrow keys, so that's a non-issue. The only keys you truly "lose" are the numpad-specific Enter, +, -, etc., which most people rarely use outside of the numpad context. Within a week, muscle memory adapts.

Are there any 87-key keyboards with a volume knob?

Yes, this is a growing trend! Knobs for volume or scrolling are becoming popular on enthusiast TKLs. Boards like the GMMK Pro, Akko MOD007, or certain Keychron models often include a knob in the top right corner, replacing the Scroll Lock or Pause/Break key. It's a fantastic quality-of-life feature that many users love once they try it.

The 87-key, 80% Tenkeyless keyboard isn't a weird niche product. It's a logical evolution of the keyboard for modern computer use. It removes the least-used section for many people to provide tangible benefits in space, ergonomics, and aesthetics. Now that you know exactly what it is and where it fits, you can decide if cutting that 20% is the right move for your desk.
