Both layouts drop the number pad. The difference is one row of keys and about three centimetres of desk.
| 65% | 75% | |
|---|---|---|
| Keys | 68 | 84 |
| Function row | On a layer | Its own row |
| Arrow keys | Yes | Yes |
| Suits | Small desks, big mouse swipes | Work that leans on F keys |
Pick 65% if
You want the most room for your mouse and rarely touch the F keys. Volume, brightness and F5 still exist; they sit on a layer you reach with Fn.
Pick 75% if
You use shortcuts built on the function row, or you just do not want to think about layers. You give up very little desk for it.
