Schwinn was founded in Chicago in 1895 by Ignaz Schwinn and remains a household US name for kids, mountain, and hybrid bikes sold through retail. Current sizing mixes wheel-size kids bikes with adult comfort and MTB labels. This page has Schwinn’s charts for those categories. A Stingray 20" and an adult mountain M are unrelated. Measure inseam; confirm the model on Schwinn’s current chart.

Height filters the chart. Cycling inseam decides which overlapping size to keep. The method is the same for every brand.
Height
Take shoes off and stand tall, looking straight ahead. A helper should rest a flat object on the crown of your head, then run a tape from the floor to the underside of that object. Save the number in inches and centimeters — charts use both.
Inseam
Stand tall and barefoot with feet slightly apart. Ask a helper to measure vertically from your crotch to the floor. Keep your legs straight and feet flat.

Use your height on the Kids, Mountain and Hybrid charts on this page. On the kids table, 95-97 cm sits in both 12" (Trike / Elm) and 16" (Elm). Cycling inseam and standover pick the side. Then check stack and reach for the exact Schwinn model.
Not safely. Schwinn Kids, Mountain and Hybrid charts on this page are separate. A Schwinn 12" (Trike / Elm) on the kids table and a Schwinn S (24") on the mountain table are not interchangeable.
The Kids, Mountain and Hybrid charts on this page include 12" (Trike / Elm), 16" (Elm), 20" (High Timber AL / Sting-Ray) (74-163 cm on the kids table). Verify the current Schwinn model chart on the official site before purchase.
