Specialized Bike Size Chart
Specialized mixes numeric road sizes with alpha mountain sizing. Match the model family first, then compare the exact geometry for your year.
Enter your measurements to see your recommended size, backup size, confidence, and why it fits.
Sizing notes
Read the chart, then check the bike.
Road models use numeric labels
A Specialized 54 or 56 is a useful shorthand, but the rider height range and geometry explain the actual fit.
Mountain models use alpha labels
Rockhopper, Epic, Stumpjumper, and similar bikes should be checked by height, wheel size, and standover together.
Older model data needs caution
If you are buying used, compare the model year carefully because geometry and sizing guidance can change.

FAQ
Short answers for choosing a size before purchase.
What Specialized road bike size do I need?
Most adult road riders narrow to one or two numeric sizes by height, then use inseam and reach to choose.
Does Specialized size the same as Trek?
No. Compare the actual height range and geometry rather than assuming a 54 or medium maps directly.
