Need a number pad? Get the full-size MX Keys. If you don't, the MX Keys Mini gives you the same key style, backlight and battery in a much smaller board.
On Logitech's own spec pages the two keyboards share the essentials: Perfect Stroke keys, a hand-proximity backlight with an ambient light sensor, a 1500 mAh rechargeable battery rated for up to 10 days (or up to 5 months with the backlight off), Easy-Switch between up to 3 devices and a 10 m wireless range. The real differences are size and the receiver. The MX Keys has an integrated numpad and is 430.2 mm wide and 810 g; the MX Keys Mini drops the numpad and is 295.99 mm wide and 506.4 g. The retail MX Keys Mini connects over Bluetooth only, with no receiver in the box; the MX Keys for Business and the MX Keys Mini for Business both ship with a Logi Bolt USB receiver.

Check on Amazon →Full-size · integrated numpad · Logi Bolt receiver in the box
Check on Amazon →Both buttons point to the for Business editions. Our MX Keys review explains why: the original MX Keys listing on Amazon is no longer sold, and the MX Keys for Business is the same full-size, backlit keyboard with a Logi Bolt receiver. For the Mini, the for Business edition is the one that includes a receiver.
Going by Logitech's product pages for the MX Keys Mini, the MX Keys Mini for Business and the MX Keys for Business, the two keyboards have the same:
| Spec | MX Keys Mini | MX Keys (for Business) | Source |
|---|---|---|---|
| Layout | Compact, no numpad (79 keys on the for Business edition) | Full-size with integrated numpad and arrow keys | Mini for Business; MX Keys for Business |

| All figures are Logitech's own, read from the three Logitech US product pages linked above on 3 November 2026. The MX Keys column uses the MX Keys for Business page, the full-size model our buy link points to. Logitech lists the MX Keys Mini for Business at 296 × 132 × 21 mm and 506 g, the same as the retail Mini rounded. We have not measured any of these figures ourselves. | |||
The integrated numpad is the main thing the MX Keys has that the Mini does not. If you enter figures in spreadsheets, accounts or data all day, the full-size board keeps those keys under one hand. Read our full MX Keys review for the long-form take.
Without the numpad the Mini is about 13 cm narrower, so a mouse can sit closer to the keyboard, and at 506.4 g it is the easier one to carry between home and office. You keep the same backlight, battery rating and 3-device Easy-Switch. Our MX Keys Mini review covers it in more depth.
If a computer has no Bluetooth, unreliable Bluetooth, or is a Mac with FileVault turned on, pick a model with the Logi Bolt receiver in the box: the MX Keys for Business or the MX Keys Mini for Business. The Logi Bolt receiver needs a free USB-A port, according to Logitech's system requirements.
| If you... | Choose |
|---|---|
| Use a number pad every day | MX Keys |
| Want a narrower board so your mouse sits closer | MX Keys Mini |
| Carry the keyboard between desks | MX Keys Mini (506.4 g vs 810 g) |
| Need a USB receiver in the box | MX Keys for Business or MX Keys Mini for Business |
| Care most about battery life | Either: Logitech rates both the same |
This comes down to the numpad. Logitech's specs give the two keyboards the same battery, backlight, Easy-Switch and range, so the full-size MX Keys is the pick if you use a number pad and the MX Keys Mini is the pick if you don't. Whichever you choose, check whether the version you buy includes the Logi Bolt receiver.
