Standover checkWith a 31" inseam, look for a standover height under about 30.0" for comfortable clearance.

This is a starting point based on common hybrid/commuter sizing charts — always confirm against the specific bike model’s own size chart, since geometry varies by brand and bike type.

How this result was chosen

  • At 0'0" (0"), the selector uses wheel size instead of adult frame size.
  • With a 31" inseam, look for a standover height under about 30.0" for comfortable clearance.
  • Treat this as a starting point, then confirm against the exact model size chart before buying.
  • For kids, inseam and confidence matter more than age because children grow at very different rates.
