Whether you’re a beginner or upgrading to a new bike, this guide has you covered.
Why Bike Frame Size Matters
Getting the right frame size isn’t just about comfort, it’s about performance and safety. A properly sized frame helps you:

How to Measure Your Height for Bike Frame Size
Before checking charts, you need your accurate height. Stand straight against a wall without shoes, mark the top of your head, and measure in centimeters.
👉 Pro Tip: Also measure your inseam (inside leg length), as it plays a big role in bike sizing.
