Finding your ideal road, mountain, or hybrid bike frame size shouldn't involve guesswork. Use our interactive sizing engine to start, then discover why standard height charts are only the beginning.
Based on average proportions for a height of 5'6", a road frame size of 52 - 54 cm is standard. Women with relatively longer legs often prefer the lower end of the range (52 cm) for a shorter, more comfortable reach.
Standard charts assume you have perfectly proportional legs, torso, arm length, and average flexibility. Even a minor difference of 2cm in leg length completely alters your optimal seat height and frame reach.

Your limbs and torso correspond closely to standard cycling averages. A standard frame size is a solid starting point for you.
Tailoring Advice: Even with average proportions, standard height charts cannot tell you your exact saddle height (A), saddle setback (B), or handlebar drop (D). These must be tailored to protect your knee joints and optimize pedaling leverage.
Two riders who are both 5'6" (168 cm) can easily have an inseam difference of 5 cm. This alters the required saddle extension. Setting your saddle incorrectly by just 5mm can cause patellar tendonitis or hamstring pull.
Reach governs how far you stretch to grip the handlebars. If you have long legs but a short torso, standard size charts will sell you a frame that is too long, causing shoulder bunching and neck compression.
A flexible rider can tolerate a deep handlebar drop (e.g. 8-10 cm below saddle), whereas a casual rider or someone with tight hamstrings needs their bars level with or above the saddle to avoid pelvic strain.
Road racing requires an aerodynamic profile (longer reach, more drop), whereas gravel and trail riding rely on stability (shorter reach, wider bars, higher stack). Average charts blur these critical categories.
Our matching system highlights the rows below based on your current height of 168 cm.
| Height (Imperial) | Height (Metric) | Frame Size | Class |
|---|---|---|---|
| 4'10" - 5'0" | 147 - 152 cm | 47 - 48 cm | XXS |
| 5'0" - 5'3" | 152 - 160 cm | 49 - 51 cm | XS / S |
| 5'3" - 5'7" | 160 - 170 cm | 52 - 54 cm | S / M |
| 5'7" - 5'11" | 170 - 180 cm | 54 - 56 cm | M / L |
| 5'11" - 6'3" | 180 - 190 cm | 57 - 59 cm | L / XL |
| 6'3" - 6'6" | 190 - 198 cm | 60 - 62 cm | XL / XXL |
| 6'6"+ | 198 - 210 cm | 62 cm+ | XXL |
Standard charts lead to compromised positions, sore knees, and lower back strain. Our online fitting service walks you through easy measurements (inseam, sternal notch, torso, arm reach, flexibility, and feet) and generates your millimeter-accurate cockpit setup.
