The present invention discloses a system and method for improvement in process of measurement of body circumference using Augmented Reality (AR) and 4-point mathematical calculations approach and mobile device camera. The method includes the steps of receiving two or more individual parameters from an individual device; receiving at least one set of 4 points capture through AR technology; measurement through AR technology from the individual device, at least one dimension including user's inputs on height, weight, age, and size range; performing body segmentation on at least one dimensions to identify one or more body features associated with the human from the background; performing the distance calculation between four points; compare the calculation results with standard sizing database and displaying the final output to the individual. The application utilizes Augmented Reality for estimating the circumference body measurements of an individual from specific point to point capture in the individual's environment using the individual's device.
