Nipple Measuring Card - Find Your Perfect Breast Pump Flange Size

Stop Painful Pumping—Find Your Perfect Flange Size in 60 Seconds

The Problem: You're using the standard 24mm flange that came with your pump, but pumping is painful, your nipples are swollen and rubbed raw, and you're not getting much milk. The wrong flange size causes discomfort, reduces milk output, and can damage your nipples—but most women don't realize they need a different size.

The Solution: Tiny Bloom Nipple Measuring Card helps you find your correct flange size in 60 seconds. Most women need a smaller flange than the standard 24mm—using the right size eliminates pain, increases milk output, and makes pumping comfortable and efficient. Why Correct Flange Size Matters

- Wrong Size Causes Pain & Damage: Too large and your nipple rubs against the tunnel, causing friction, swelling, and damage. Too small and your nipple is compressed, causing pain and blocked ducts.
- Reduces Milk Output: Incorrect flange size can reduce milk expression by 30-50% or double the time needed to pump the same amount.
- Most Women Need Smaller Than Standard: The standard 24mm flange that comes with most pumps is too large for 60-70% of women. Many need 17-21mm flanges.
- Nipples Can Be Different Sizes: Your left and right nipples may require different flange sizes—measuring both ensures optimal fit.
- Size Can Change: Nipple size can change throughout your pumping journey due to swelling, hormones, or time of day. Why Parents Rate This 5.0 Stars

- Note the millimeter size of the circle that fits
- Choose a flange insert 1-2mm larger than your measurement (e.g., if you measure 16mm, choose 17-18mm flange)

Method 2: Tape Measure
- Stimulate nipple to make it erect
- Hold tape measure perpendicular to nipple
- Line up 0 scale with nipple base at areola edge
