The charts below is based upon official Bianchi's website. Frame size calculation is based upon the inseam length and not upon the cyclist height. While you can find on the internet, charts that are based upon riders height, we highly suggest using this one, as it is what Bianchi use on it's website.
You should measure your inseam length, or your inner leg length. Check this guide on How to measure your inseam length
