What Flange Size Calculator does

The Flange Size Calculator helps users determine the correct breast pump flange diameter by inputting three physical measurements: breast circumference, nipple length, and areola width. The output is a recommended flange diameter designed to optimize milk extraction and comfort during pumping sessions. By simplifying the sizing process, the tool addresses a common concern for breastfeeding individuals, whether using manual or electric pumps, and aims to reduce risks such as pain, abrasions, and duct blockage associated with improper fit.
