Mountain Bike Wheel Size Calculator

Keep in mind that these sizes can vary slightly between manufacturers, and there's ongoing evolution in the industry, but these are generally accurate estimations:

Wheel Size	Abbreviation	Typical Use	Characteristics
26 inches	26"	Older bikes, downhill, dirt jumping	Maneuverable, strong acceleration, less stable at high speeds, gradually being phased out in favor of larger sizes
27.5 inches	27.5" or 650b	Trail, all-mountain, enduro	A good balance between maneuverability and stability, offers good traction and rollover capability
29 inches	29" or 29er	Cross-country, marathon, trail, enduro	Excellent rollover capability, maintains speed well over rough terrain, slightly less maneuverable compared to smaller sizes
29+ inches	29"+	Plus-size tires, bikepacking, trail riding	Offers increased traction and comfort over rough terrain, provides a "floaty" feel, slightly heavier and slower to accelerate compared to standard 29ers
27.5+ inches	27.5"+ or 650b+	Plus-size tires, trail riding, all-mountain	Similar benefits to 29+, with slightly quicker acceleration and more maneuverability due to smaller wheel diameter

Remember, the best wheel size for you depends on your riding style, terrain, and personal preferences.
