How to determine your optimal bike frame size

Measure body height

Body size is the most important starting point for determining frame size.

  • Stand upright and barefoot against a wall
  • Measuring from the floor to the crown
  • For an accurate measurement, place a book on your head and measure up to the bottom edge
  • It's best to get someone to help you with this.

Tips for choosing the frame size

Consider sitting posture and intended use

A sporty gravel bike is often ridden with a more compact riding position than a city bike, which is designed for comfort. If you are on a sporty ride, the frame can be a little smaller - for more maneuverability. An upright riding position is ideal for leisurely rides or longer tours.

Understanding the differences between frame sizes

Not every manufacturer measures the frame in the same way: mountain bikes are often measured in centimeters, road bikes in classic S, M and L classes. corratec combines both to offer you an easy-to-understand size selection.

The right frame size - FAQs
How do I measure my height correctly?
Stand barefoot straight against a wall, look straight ahead and measure the distance from the floor to the top of your head. For an even more accurate measurement, place a book on your head and use the bottom edge of the spine as your upper measurement.
What do I do if I am between two frame sizes?
If you are a sporty rider, choose the smaller size for more agility and a bent riding position. The larger frame size is recommended for comfort. A larger frame is particularly suitable for a touring-oriented riding style.
Can I have my bike adjusted afterwards?
Yes, with a suitable stem, saddle or seat post, the bike can be fine-tuned to suit you perfectly. With spacers, for example, a bent riding position can be made more upright and adapted to changing needs.
