It's really important that the measuring tool gets printed out accurately, so please:

  • Make sure you download the right version for your paper size (surrently, we only support LETTER SIZE (US)
  • Make sure you do not 'scale to fit' - select 'full size' or 100% in your print menu. 


  • Fold the ruler along the fold line and carefully cut out the circles.
  • Open the page back up and then place each hole around your nipple.
  • The best size will fit easily around your nipple, but be quite snug. We're after a snug fit

      I love this product because it allows you to actually see the correct size of your nipple. Which of course, the lactation consultant was off

      Printable flange size

      Posted by Jordan on 7th Sep 2023

      I've been unsuccessful at breastfeeding all 3 of my older kids and I now know it's because I didn't have the proper information and guidance. Im pregnant with my 4th and never knew about flanges and sizes with my other kids and I'm positive that's why I struggled the way I did. I plan on purchasing the kit as soon as I can but the printable gave me the information I needed to start a successful breastfeeding journey and I'm so excited and thankful for you guys !
