Size Guide

Choosing the correct bike size is fundamental for comfort, performance, and safety. An ill-fitting bike can cause pain, fatigue, and inefficient pedaling. In this comprehensive guide, we will help you identify the ideal bike size considering your height, bike type, and frame geometry.

Bicycle sizes are not standard

There isn't one universal size that works for all bicycles. Each manufacturer uses different geometries and sizing scales.
Two frames with the same measurement in centimeters can offer completely different riding experiences based on the brand and model.

The main advice is not to rely solely on the size number, but on the values indicated in each brand's official chart.

Bike adjustment margin

Some models allow for more adjustments than others:

  • Gravel and endurance bikes are more adaptable.

  • Race bikes have more rigid and aggressive geometries.

  • Full-suspension MTBs and e-bikes have less adjustment freedom.

Saddle, handlebars, and stem can improve your riding position, but they cannot compensate for an incorrect size.

How to use the size chart

To choose correctly:

  1. Check your actual height.

  2. Consult the specific model's chart.

  3. Consider your riding style (comfort or sporty).

  4. If in doubt, contact customer service or a biomechanics expert.

Bicycle size charts

Road and gravel bike sizes

Road and gravel bikes are primarily measured based on the top tube length, which affects the reach.

Size Recommended Height Top Tube Length
XS Up to 157 cm 48–50 cm
S 157–167 cm 50–53 cm
M 168–178 cm 53–56 cm
L 178–185 cm 56–58 cm
XL Over 185 cm 58–62 cm

Gravel bikes may have slight variations in geometry, but the values remain similar.

Mountain bike (MTB) sizes

MTBs are classified in inches and refer to the seat tube.

Size Recommended Height Frame Size
XS Up to 157 cm 14" – 16"
S 157–167 cm 15" – 17"
M 168–178 cm 16" – 19"
L 178–185 cm 18" – 20"
XL Over 185 cm 20" – 23"

Geometries vary depending on the discipline: cross-country, trail, enduro, or downhill.

Children's bike sizes

For children's bicycles, the size depends on the wheel diameter:

Age Wheel Size
1–3 years 12"
2–4 years 14"
4–6 years 16"
5–8 years 20"
8–10 years 24"
Over 10 years 26" / 27.5"

It's always better to choose based on the child's height rather than relying solely on age.

Between two sizes: which to choose?

If you fall between two sizes:

  • Choose the larger size for more comfort.

  • Prefer the smaller size for sporty riding and high performance.

  • Consider torso and leg length in addition to overall height.

Final tips

  • Always check the manufacturer's recommendations.

  • Check the return policy.

  • Seek specialized advice.

  • If possible, test ride the bike before purchasing.

  • A correct fit is more important than the number indicated on the frame.
