Choosing the right bike size makes riding safer, faster and more comfortable. A bike that fits well is easier to control and helps you ride longer without strain. Use the charts below to match your height to the frame size we recommend for each bike type.
On every bike we stock, you can use our Smartfit tool to see what size of that specific bike you would need. It uses frame geometry data and your individual height and inside leg measurements to match you with the correct size bike. Sizing differs between brands and the SmartFit calculator is a fantastic way to find what size bike you need.
These charts cover road bikes, women’s road bikes, hybrid bikes, mountain bikes and women’s mountain bikes. Each table shows rider height in feet, inches and centimetres, along with the frame size that suits most riders. If you fall between two sizes, think about how you like to ride. A smaller frame feels more agile. A larger frame feels more stable.
These guides work for most brands. Some brands use their own geometry, so sizes can vary. If you are unsure, check the product page for brand specific advice, use our SmartFit tool or speak to our team.
The below charts are a rough estimate on the frame size you’ll need based on industry data and over 20years experience pairing people with bikes.
