Sizing notes
Read the chart, then check the bike.
Frame size is a label, not a body measurement
A bike frame size chart usually maps rider height and inseam to a frame label. The label may be centimeters, inches, or S/M/L depending on bike type and brand.
Use inseam to confirm standover
Height gives the first frame range, but inseam checks whether the frame is practical to stand over and control at stops.
Road, mountain, and hybrid labels differ
Road bikes often use centimeter frame labels, mountain bikes often use inches or S/M/L, and hybrid bikes may use either. Do not compare labels across categories without the rider range.
Brand geometry decides close calls
Two frames with the same label can have different stack, reach, and standover. Use the calculator and brand chart when the rider sits between two sizes.

FAQ
Short answers for choosing a size before purchase.
How do I use a bike frame size chart?
Start with rider height, check inseam for standover, then translate the result into the bike type's frame label system.
What is a bicycle frame size chart?
A bicycle frame size chart maps rider height and inseam to frame labels such as 54 cm, 17 inches, S, M, L, or XL.
Is frame size chart by height enough?
No. A frame size chart by height gives the shortlist, but inseam, standover, reach, bike type, and brand geometry decide the final fit.
Should I use centimeters, inches, or S/M/L?
Use the label system shown by the brand. Road bikes often use centimeters, mountain bikes often use inches or letters, and hybrids can use either.
