Sizing notes
Read the chart, then check the bike.
Gravel sizing is close to road, not identical
Many riders start near their endurance road size, but gravel bikes often need more standover clearance and stable reach for rough surfaces.
Use inseam for clearance
A gravel bike can look right by height and still feel too tall off pavement. Confirm inseam, standover, and tire setup before sizing up.
Between two gravel sizes
Choose the smaller size for easier handling, more clearance, or loaded riding. Choose the larger size only when standover is safe and reach does not feel long.
Compare the model chart
Trek Checkpoint, Giant Revolt, and Specialized Diverge use different geometry. The model page should decide the final answer after the general gravel chart narrows the range.

FAQ
Short answers for choosing a size before purchase.
What size gravel bike do I need?
Use height to pick the first gravel size range, then use inseam to confirm standover. If two sizes overlap, compare reach and choose the frame that gives safer control.
How do you size a gravel bike?
Match height to the gravel bike size chart, check inseam for standover, then compare reach and stack on the exact model before buying.
Are gravel and road bike sizes the same?
They are often close, but not identical. Gravel bikes may use extra clearance, different reach, and different size labels compared with road bikes.
Should I size down on a gravel bike?
Size down when you are between sizes and want more clearance or easier handling. Do not size down so far that the cockpit feels cramped.
