What is a 75% Keyboard?

A 75% keyboard offers a smart, space-saving design that keeps all the keys you use the most—alphanumeric, arrow keys, function row, and modifiers—while ditching the numpad and a few navigation keys. This gives you more desk space without sacrificing usability, which is why we’ve put so much effort into making sure our GravaStar Mercury series nails this balance. Whether you're gaming, typing, or working, it provides everything you need without the bulk.

Key Features of a 75% Keyboard

Key Layout: Our 75% layout keeps all the essentials like the function row and arrow keys. You’ll have everything you need right at your fingertips, in a neat, compact setup.

Function Row: Unlike smaller 60% keyboards, our 75% keyboards retain the function row for quick access to extra commands.
