Scott Sports began in 1958 in Sun Valley when Ed Scott made aluminum ski poles, then moved into bicycles; the company is based in Givisiez, Switzerland. The bike side covers road, mountain, gravel, and e-bikes. This page has Scott’s charts for those categories. Addict and Spark do not share a size code. Use the category table, then stack and reach for the exact model year.

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 Road, Mountain and Gravel charts on this page. On the road table, 166-168 cm sits in both XXS (49) and XS (52). Cycling inseam and standover pick the side. Then check stack and reach for the exact Scott model.
Not safely. Scott Road, Mountain and Gravel charts on this page are separate. A Scott XXS (49) on the road table and a Scott XS on the mountain table are not interchangeable.
The Road, Mountain and Gravel charts on this page include XXS (49), XS (52), S (54) (160-198 cm on the road table). Verify the current Scott model chart on the official site before purchase.
