Trek Bike Size Chart
Trek was founded in 1976 in Waterloo, Wisconsin, and builds road, mountain, hybrid, gravel, and e-bikes. Alpha and numeric labels both appear depending on the family. This page has Trek’s brand-level charts for those categories. A Domane 54 is not a Fuel EX M. Use the table that matches the bike, then compare stack and reach. A longer Trek size guide with family-level charts also lives on this site.

How to measure
Height filters the chart. Cycling inseam decides which overlapping size to keep. The method is the same for every brand.
Height
Inseam
- 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: Ignore the tag inside your pants. Bike inseam is floor-to-crotch in a riding stance. Straddle a broomstick or dowel, lift it into the groin until it sits firmly, and measure the stick's height from the floor. A second person makes this less awkward.

FAQ
What Trek bike size do I need?
Use your height on the Road, Mountain, Hybrid and Gravel charts on this page. On the road table, 158-160 cm sits in both 47 and 50. Cycling inseam and standover pick the side. Then check stack and reach for the exact Trek model.
Can I copy a Trek size from one bike type to another?
Not safely. Trek Road, Mountain, Hybrid and Gravel charts on this page are separate. A Trek 47 on the road table and a Trek XS on the mountain table are not interchangeable.
Which Trek sizes are listed on this page?
The Road, Mountain, Hybrid and Gravel charts on this page include 47, 50, 52 (152-198 cm on the road table). Verify the current Trek model chart on the official site before purchase.
