Sizing Guide

How to Choose Your Pad Size

Start with what you know: grab a disposable pad you usually wear and measure its length in inches. Choose the closest size in a Millie Pad™ to begin. From there, it may take a little trial and error to discover your favorite fit. Every inch makes a noticeable difference in comfort and coverage, which is why all Millie Pads™ are sized by inches.

✨Different fabric types also change how a pad feels against your skin. See our Fabric Guide to compare options.

What About Double-Zorb?

Some Millie Pads™ are made with a Double-Zorb core — which simply means we’ve added an extra layer of Zorb absorbent fabric inside the pad.

  • More absorbency: The extra layer increases capacity, making these pads especially helpful on heavier flow days or for longer wear.
  • Slightly thicker feel: Double-Zorb pads are a bit thicker than our standard pads, but many people find the added peace of mind is worth it.
  • Great for overnights: If you want fewer changes during the night, Double-Zorb can give you the extra coverage you need.

💡 If you’re just starting out, you don’t need your whole stash to be Double-Zorb. Many people like a mix — standard cores for lighter days, and a few Double-Zorb pads for heavier flow or overnight confidence.

Our Recommendations

If you’re feeling unsure where to start, we suggest beginning with either an 11" or 12" Millie Pad™. These sizes tend to be the most versatile and will likely find a place in your cycle routine.

  • Start with an 11": If it feels a little short on heavier days, it will still be useful for lighter flow or early-cycle wear.

  • Start with a 12": If it feels longer than you need, it can double as a comfortable overnight option.

If you’re really uncertain, try just 1 or 2 pads first. Test them out, see how they fit your needs, and then adjust your next purchase. Building your collection slowly is the best way to create a set that feels perfectly tailored to you.
