Nipple Chart Guide

At Nudies, we understand the importance of finding the perfect fit for your breastfeeding journey. Proper sizing of the nipples and flanges is crucial to ensure comfort, efficiency, and an enjoyable pumping experience with the Nudies Breast Pump. To assist you in finding the right size, we have prepared this comprehensive sizing chart guide.


1. Nipple Size:

Nipple size plays a vital role in achieving an effective and comfortable pumping experience. To determine your nipple size, follow these steps:

a. Measure Your Nipple Diameter: Use a ruler or caliper to measure the diameter of your nipple at its base when fully erect.

b. Choose the Correct Size: Based on the measured diameter, refer to the chart below to find your corresponding nipple size.


2. Flange Size:

Flange size is equally important to ensure optimal suction and milk expression. To determine your flange size, follow these steps:

a. Measure Your Nipple-to-Areola Ratio: When your nipple is fully erect, measure the distance from the base of your nipple to the outer edge of your areola.

b. Choose the Correct Size: Based on the measured ratio, refer to the chart below to find your corresponding flange size.


Important Tips:

  • It's essential to ensure that the flanges provide a proper fit for your nipples. Flanges that are too tight or too loose may cause discomfort or hinder milk expression efficiency.
  • Breast size can change during the breastfeeding journey, so we recommend re-evaluating your nipple and flange size periodically.
  • If you experience any discomfort or have difficulty finding the right size, our customer service team is here to assist you. Please don't hesitate to reach out for personalized guidance.
