How Many Keys Does an 80% Keyboard Have? The Complete TKL Guide
By Celeste • MAY 21, 2026
Quick Answer: A standard 80% keyboard has 87 keys (ANSI layout) or 88 keys (ISO layout). It removes the number pad but keeps the function row, arrow keys, and navigation cluster—offering a perfect balance between compactness and functionality for your custom mechanical keyboard.
1. What Exactly Is an 80% Keyboard?
An 80% keyboard, also called a tenkeyless (TKL) keyboard, is a layout that cuts off the numpad (number pad) section found on a full-size keyboard. It retains everything else: the main typing area, dedicated arrow keys, and the navigation cluster (Home, End, Page Up, Page Down). This trims the width by about 15–20%, freeing up valuable desk space without forcing you to learn complex shortcut layers.
The exact number of keys depends on the layout standard:
- ANSI 80% keyboard (common in North America): 87 keys
- ISO 80% keyboard (common in Europe, UK): 88 keys (includes an extra key near the left Shift)
This makes it the ideal compact mechanical keyboard for users who want a clean desk but can’t live without dedicated arrow keys or the F-row.
2. Layout Breakdown: Where Those 87 Keys Go
Understanding the sections of an 80% keyboard helps when shopping for custom keycaps and modding:
- Main Alphanumeric Cluster – Letters, numbers, modifiers (Ctrl, Alt, Win). Identical to a full-size board.
- Function Row (F1–F12) – Fully intact, great for productivity shortcuts and media controls.
- Arrow Keys & Navigation Cluster – Dedicated inverted-T arrows and a 6-key block (Insert, Delete, Home, End, PgUp, PgDn). The main reason many prefer TKL over a 65% layout.
- No Numpad – This is the “missing” 20%. If you enter a lot of numerical data, an external wireless numpad is an easy add-on.
3. 80% Keyboard vs. Other Popular Layouts
Where does the tenkeyless keyboard stand among other sizes? Here's a quick comparison:
| Layout | Typical Key Count | Numpad | Function Row | Dedicated Arrows | Best For |
|---|---|---|---|---|---|
| Full-Size (100%) | 104–108 | Yes | Yes | Yes | Data entry, accounting |
| 80% / TKL | 87–88 | No | Yes | Yes | Gaming, mixed use, compact desk setups |
| 75% | 82–84 | No | Yes (squished) | Yes (compact) | Minimalists who still want F-keys |
| 65% | 67–68 | No | No | Yes | Portability, small desk pads |
| 60% | 61 | No | No | No (via layers) | Aesthetics, extreme portability |
The 80% keyboard hits a sweet spot: it's small enough to give your mouse acres of room, yet complete enough that you never reach for a function-layer cheat sheet just to use the arrows.
4. Why Choose an 80% / TKL Mechanical Keyboard?
- Better Ergonomics & Mouse Space: With no numpad, your mouse sits closer to your shoulder. This reduces strain during long gaming sessions and gives you a wider swipe area for low-DPI aiming.
- Clean, Professional Desk Setup: An 87-key mechanical keyboard looks intentional and modern. It pairs beautifully with custom cables and a large desk mat.
- Easier to Transport: Significantly narrower than a full-size board, it fits into most keyboard carrying cases and backpack sleeves. A top choice for LAN parties and hybrid workers.
- No Learning Curve for Keycaps: Unlike 65% or 60% layouts, you don't need to memorize any obscure key combinations. Everything has a dedicated spot.
5. Custom Keycaps for Your 80% Keyboard: What Fits?
One of the best things about building an 80% mechanical keyboard is the universal compatibility with custom keycaps. Because the layout uses standard key sizes, virtually any full-size keycap set will cover your TKL board perfectly—you just leave the numpad caps in the box.
Standard keycap sizes on most 80% keyboards:
- Spacebar: 6.25u (the most common size)
- Bottom row modifiers (Ctrl, Alt, Win): 1.25u each
- Right Shift: 2.75u
- Enter, Backspace, Caps Lock: Standard sizes
Whether you love MOA profile for a cute rounded look, Cherry profile for deep acoustics, or handcrafted artisan keycaps for your Esc key, an 80% keyboard gives you a perfect canvas. Explore our full range of PBT keycaps and themed sets that are guaranteed to fit.
6. Is an 80% Keyboard Right for You?
- Gamers: Absolutely. The extra desk space is a game-changer for first-person shooters, and you keep the F-row for MMO macros.
- Programmers & Writers: Excellent. You get dedicated navigation keys and arrows without wasting space on a numpad you rarely touch.
- Accountants & Data Analysts: Probably not. The missing numpad will slow down spreadsheet work—stick with a full-size or add a separate wireless number pad.
Conclusion: The 80% Keyboard Is the Balanced Choice
An 80% keyboard (or TKL) delivers exactly 87 keys of pure mechanical joy—no more, no less. It trims the fat of a full-size board while keeping the functionality that 60% and 65% layouts sacrifice. For a custom mechanical keyboard that looks sharp, feels compact, and welcomes any set of custom keycaps, the 80% layout is a decision you won't regret.

Frequently Asked Questions
Q: How many keys does an 80% keyboard have?
A standard 80% keyboard has 87 keys in the ANSI layout and 88 keys in the ISO layout. It removes the number pad while keeping the function row, arrow keys, and navigation cluster.
Q: Is a TKL keyboard the same as an 80% keyboard?
Yes. TKL (Tenkeyless) is the traditional name for an 80% keyboard. Both terms describe a keyboard that drops the numpad but retains all other sections.
Q: Do standard custom keycaps fit an 80% keyboard?
Yes. Most 80% mechanical keyboards use standard keycap sizes, including 1.25u bottom-row modifiers and a 6.25u spacebar. Any full-size compatible keycap set will cover a TKL layout—you simply leave the numpad keys unused.
Q: Who should buy an 80% keyboard?
Gamers who need extra mouse space, professionals who rarely use a numpad, and anyone wanting a compact mechanical keyboard without sacrificing arrow keys or the function row.
