The rider-height span of every frame size that lists 5'6" (168 cm), in inches. The shaded line is the rider's height; a rider at the edge of two spans sits in both.

Reading the charts at five-foot-six

At 5'6" every chart that covers the height puts the rider in a single size, so there is no in-between call to make for a five-foot-six rider.

All the mountain-bike charts that cover 5'6" agree on M. Letter sizes are still each brand's own, so check the model's geometry before buying.

Checking the fit beyond height

Height charts assume average proportions. Cannondale's method uses inseam instead: "Measure your inseam with your legs 8-10 inches apart and subtract 1-2 inches for crotch clearance." Then compare that stand-over figure with the model's geometry chart and keep 1 to 2 inches (2.5 to 5 cm) of clearance over the top tube. A rider with long legs for 5'6" may suit the larger of two sizes; a long torso and short legs, the smaller with a longer stem.

Either side of five-foot-six

A five-foot-four rider reads S on the mountain charts. A five-foot-eight rider reads M or L.

For a five-foot-six rider these are the brands' published height spans, a starting point for a test ride, not a bike fit. Trek is not listed: its size charts could not be read from Trek. See the methodology.
