How much blood can period panties hold?
If you’re considering period panties as part of your menstrual care routine, you might wonder: How much blood can they actually hold? Knowing their absorbency helps you pick the right pair and feel confident throughout your period.
Absorbency Levels of Period Panties
Period panties come in different absorbency levels, typically categorized as:
| Absorbency Level | Approximate Capacity | Best For |
|---|---|---|
| Light Flow | About 5-10 ml (roughly 1 tampon) | Spotting, light days |
| Moderate Flow | About 15-20 ml (about 2 tampons) | Average flow days |
| Heavy Flow | About 30-40 ml (3-4 tampons) | Heavy days or overnight use |
What Does This Mean in Practice?
-
A single tampon absorbs roughly 5-7 ml of blood on average.
-
So, if a period panty holds 3 tampons’ worth, it means it can absorb about 15-21 ml of menstrual fluid before reaching capacity.
-
On very heavy flow days, this may require more frequent changes or backup protection.
Factors Affecting Absorbency
-
Brand and Design: Different brands use various fabrics and layering techniques—some have thicker cores or advanced microfiber layers for higher capacity.
-
Fit and Seal: A snug, well-fitting panty prevents leaks and maximizes absorbency efficiency.
-
Duration of Wear: Longer wear increases risk of saturation, so changing regularly is key.
Tips for Choosing the Right Period Panties
-
Assess your usual flow and select panties labeled for light, moderate, or heavy absorbency accordingly.
-
For heavy flow days, consider heavy or overnight panties, or use alongside other products like menstrual cups or tampons.
-
Read user reviews to see real-world feedback on absorbency and comfort.
Final Thoughts
Period panties can hold anywhere from about 5 ml to 40 ml of menstrual fluid, depending on their design and absorbency level. Knowing your flow and choosing the right type ensures you stay comfortable, dry, and leak-free.
