Sizing notes

Read the chart, then check the bike.

Start with category coverage

Giant is listed for Road, Mountain, Hybrid, Gravel, E-Bike. Choose the bike category first because road, gravel, mountain, and kids sizing use different assumptions.

Check data status

Data sourced from official brand references. Use the result as a shortlist, not a final fit decision.

Confirm the exact model

Model year, geometry, wheel size, and cockpit setup can change the final answer even when the height range looks right.
