Logitech’s MX Master 3S and MX Anywhere 3S share the same premium DNA — 8,000 DPI sensors that work on glass, quiet clicks, MagSpeed scroll wheels and multi-device switching. The difference is shape and purpose: one is a full-size desk mouse, the other a compact travel mouse. This comparison helps you pick the right one (or decide whether you need both).
Quick answer
- Mostly at one desk: MX Master 3S — more comfortable, more controls.
- Mostly on the move: MX Anywhere 3S — smaller and lighter.
- Small hands: MX Anywhere 3S, even at a desk.
- Corporate PC without Bluetooth: MX Master 3S, which includes a USB receiver.

Comfort
The MX Master 3S supports your whole palm and places the thumb on a rest with a wheel and gesture button. For eight-hour days, it’s the more relaxed grip for medium and large hands. The MX Anywhere 3S uses a fingertip or claw grip; it’s comfortable for shorter sessions and for people with smaller hands. Neither is a true ergonomic mouse — for wrist pain, see vertical mice.
Productivity features
The Master wins on controls. The thumb wheel scrolls timelines and wide spreadsheets naturally, and the gesture button can switch desktops, show all windows or control media with a press-and-swipe. The Anywhere covers the essentials — back, forward and a customizable wheel button — with app-specific settings in Logi Options+.
Portability
The Anywhere slips into a laptop sleeve pocket; the Master takes real space in a bag. If you commute daily between home and office, some people keep a Master at home and an Anywhere in the bag, using Easy-Switch to pair both with the same laptop.
