TLDR;
Choosing the right size for your keyboard depends on how you plan to use it:
For Work & Productivity:
Full-sized, TKL or 75%

65%

Honestly, all of us want to be as efficient as this guy, being able to navigate his entire workstation without having to move his hands away from his keyboard. But before we can hit that level, let’s start again from the very beginning.
So, you’ve decided to build your own custom keyboard after seeing all those TikToks of keyboard reviews, or seeing your co-workers use a keyboard with a satisfying “thock” sound. Before we dive into the rabbit hole of switch lubing, artisan keycaps and RGB lighting, let’s start with the foundation of every keyboard: the board of course!
Your keyboard board (the PCB and the case) is more than just something to plug your switches into – it determines how compact or spacious your typing experience feels, how sturdy your setup is, and even how satisfying your keyboard sounds. In this series of Keyboard 101, we’ll explore the different sizes, materials and use cases for each keyboard type.
100% - Extra Large
- 104-108 keys
- Has dedicated function keys, a number pad and a navigation cluster
- Best for: Accountants, data entry pros (anyone who uses a numpad really)
If you love having every key possible at your fingertips – including a dedicated numpad for spreadsheets, macros and aggressive calculator use – this option is for you! Downside is that it’s big, bulky and takes up a lot of desk space.
TKL - Large
- 87-88 keys
- Drops the num-pad, but retains the function and arrow keys
- Best for: Gamers, programmers and minimalist setups
A TKL board is the Goldilocks of keyboards – not too big, not too small. You keep the (let’s be honest) best keys while saving desk space for your mouse, snacks or your favourite PopMart.
75% - Medium
- Similar to TKL, but compressed
- Keeps the function row and arrow keys but with a smaller footprint
- Best for: Gamers, programmers, and people who want efficiency in a compact layout
This is like a “you can copy my work but don’t make it too obvious” scenario comparing this to TKLs. The 75% board still keeps all your function and arrow keys in a neat streamlined design.
65% - Small
- No function row, but keeps arrow keys
- Ultimate space saver (while being usable)
- Best for: Gamers, casual typists and anyone who doesn’t use function keys often
Personally my favourite! No, I don’t have limited desk space nor do I travel with my keyboards, but it’s my favourite layout since I don’t need to stretch my hand out to press certain keys.
This board is great for those who want a smaller board without losing essential navigation keys. Think of it as a mini-TKL that’s still practical for everyday use!
Everyone types differently, plays differently, and works differently—so why settle for something off the shelf? With a custom build, you get to choose everything from the switch feel to the sound profile, layout, and looks. It’s not just about performance; it’s about making something that feels right for you.
At the end of the day, keyboards aren’t one-size-fits-all—and that’s the beauty of custom builds. Whether you want a full-sized beast for productivity or a compact 65% for gaming, it’s entirely up to you.
