The right number of buttons depends on the games you play. More buttons are not always better: they add weight and can get in the way.

FPS and esports
Most FPS players use two side buttons plus the main buttons and scroll wheel. Simpler mice are often lighter. See best gaming mouse for FPS.
General gaming and productivity
Five to eight buttons cover most needs, with back and forward buttons and a DPI switch. See wireless gaming mice.
MMO and MOBA
MMO players use a thumb grid of 12 or more buttons for abilities. See MMO gaming mice.
Swappable and removable buttons
Some mice have swappable or removable side buttons so you can customize the layout. See left-handed and ambidextrous mice.
Check reach and shape
Buttons only help if your thumb can reach them comfortably. See best mouse grip for gaming.
How many buttons does an FPS mouse need?
Usually two or three extra buttons at most.
Can I remap buttons?
Yes, using the mouse software.
Bottom Line
Match buttons to your games: few for FPS, many for MMO.
