WHAT SIZE ARE YOUR NIPPLES?
You can breastfeed however big or small your nipples are. There aren’t any official guidelines when it comes to nipple size, but this gauge is a handy guide for those of you who’ve never considered your nipple size before and are curious.
Measure the width of your nipples at their base (not your areola). Less than 12mm: small
12 to 15mm: average
16 to 23mm: large
More than 23mm: extra-large
Less than 5mm: flat
5 to 12mm: average More than 12mm: long
