Your height doesn't matter as much as the length of your torso. ETT means Effective Top Tube.
The effective top tube length is the horizontal distance from the top tube/head tube junction to the seat tube. This measurement has become significant as more and more bikes are designed with sloping top tubes.

and have someone help you get your measurements.
When sizing a bike, go by ETT length, not nominal size, either in cm. or S/M/L. ETT is the critical measurement. Saddles go up and down easily.
