Silicone Nipple Ruler
Measuring Is Just The First Step
Your nipple measurement gives you a starting point, not a final answer. Flange sizing is individual, and comfort + milk flow response can vary by pump brand and breast anatomy. Most mothers will need to trial 2–3 different flange sizes around their measured diameter to find their optimal fit.

Flexible: Bends gently to contour to the nipple for easier handling
Sturdy: Maintains its shape for precise measurement, giving you reliable readings every time
Durable & long-lasting: Won’t tear or deform after repeated use
Why Accurate Measurement Matters
Incorrect flange sizing can contribute to:
Nipple pain or friction
Areola swelling or pulling
Reduced milk output
Blocked ducts from poor drainage
Longer pumping sessions
This ruler helps remove guesswork, so you can move toward comfortable, efficient pumping.
How To Use
Ensure nipples are in a natural, relaxed state (not immediately after pumping).
Place the ruler gently over the nipple.
Find the opening that fits your nipple snugly without compressing it.
Use this measurement as a guide to select 2–3 flange sizes to trial.
Assess comfort, nipple movement, and milk output to determine the best fit.
Re-measure if you experience pain, output changes, or postpartum breast changes.
Pro-tip: Most mothers do experience nipple size changes a few times throughout their first 15 months of their pumping journey.
Locally Designed Product
Singapore-based
“Based on my clinical experience, most mothers do experience nipple size changes during the first year postpartum.
Personally, I experienced this myself when I went on a trip around one year postpartum. I realized my nipple size had changed again.
I had to adjust my flange size to ensure the best fit while pumping overseas.
This inspired me to create the Silicone Nipple Ruler, for mothers to easily measure, track, and trial flange sizes, so they can pump comfortably and efficiently no matter where they are.”

How to Get Pumping Support
Finding the right flange fit and optimizing milk output can sometimes take more than measurement alone. There are two ways to get personalized guidance:
I bring a selection of 16 different flange sizes for trial, so we can quickly identify the best-fitting flange for you. Most mothers only need to try 2–3 sizes around their measurement to find comfort, nipple movement, and optimal milk flow.
Join our group workshop to learn pumping techniques, troubleshoot common issues, and try different pump brands and flange sizes in a hands-on, supportive environment. Leave with practical tips and confidence in your pumping routine.
-
Measure when nipples are in a natural, relaxed state, not immediately after pumping or feeding.
-
No. Measure nipple diameter only, not the surrounding areola.
-
Not exactly. Measurement is your starting point. Most mothers will need to trial 2–3 flange sizes slightly larger than their measured diameter.
-
Signs of a good fit include:
Nipple moves freely in tunnel
Minimal areola pulling
No pain or friction
Efficient milk flow
-
Yes. Size can change due to:
Early postpartum swelling
Elastic tissue response
Pumping frequency
Hormonal changes
Re-measure if comfort or output changes.
-
Yes. The ruler is made from soft, food-grade silicone that is odorless and non-toxic, gentle on tender skin.
-
Absolutely. Many mothers measure before birth to prepare flange sizing in advance.
