ABSTRACT Embodiments herein disclose a method and system for cuff-less blood pressure (BP) measurement of a subject. The method includes measuring, by one or more sensors, a local pulse wave velocity (PWV) and/or blood pulse waveforms of an arterial wall of the subject. Further, the method includes measuring, by an ultrasound transducer, a change in arterial dimensions over a cardiac cycle of the arterial wall of the subject. The arterial dimensions include an arterial distension and an end-diastolic diameter. Furthermore, the method includes measuring, by a controller unit, BP of the subject based on the local PWV and the change in arterial dimensions. FIG. 1
