Quick Reference on the Number of Keys on a Standard Keyboard Layout
June 09, 2020

Introduction

This post is a quick summary of the number of keys found on standard keyboards. I wanted to order some switches for one of my keyboards and a quick Google search didn't reveal much results and as such, for now and for future reference, I'm creating this blog post.

There are plenty of keyboard layouts currently on the market with different sizes. In this post, we quickly glance over the layout and the number of keys available on the standard US ANSI layouts: 104 key full size, 87 key tenkeyless, the rare 84 keys keyboard, and the 61 key compact layouts.

Keyboard Layouts Info

To create the below graphics, I used the amazing Keyboard-Layout-Editor.com online tool. Please note that the below naming conventions and color annotations are not standardized. I'm just following the commonly used terms on popular mechanical keyboards related content creators like Taeha Types, Mech Merlin, and Tae Keyboards.
