So you’re ready to switch to a menstrual disc but have no idea what size or even brand is right for you. Everyone’s anatomy is uniquely different which is why finding the right size for you is important! 

First Things First: Why a Menstrual Disc?

Let’s start with the basics. Period discs are both reusable and disposable period products that sit in the vaginal fornix and collects your flow rather than absorbing it. It's suction-free, super comfy, and bonus—it can even be worn mess-free during sex.

If you’ve ever felt like tampons or cups weren’t quite right for you, or you’re just tired of the monthly waste, a period disc could be a game changer.

Benefits of Using a Menstrual Disc:

• Up to 12 hours of protection
  
  

• Holds more than a tampon or pad
  
  

• No suction
  
  

• Reusable up to 10 years
  
  

Now that you know the why, let’s get to the which.

How your Cervix Height can Determine your Disc Size

Your cervix height is important when determining which period disc is right for you. 

Low-mid Cervix

• You’ll most likely find the most comfort with a smaller disc

Mid-High Cervix 

• A bigger disc will most likely be easier to insert and remove

If you find your cervix height changes during your cycle (which is completely normal) then a disc duo may be the best option!

So, What’s the Best Menstrual Disc?

The best menstrual disc is the one that fits your body, your lifestyle, and your flow. 

So you’re ready to switch to a menstrual disc but have no idea what size or even brand is right for you. Don’t worry—you’re in the right place.

Menstrual discs are becoming increasingly popular for people looking to ditch disposable period products or find a more comfortable and mess-free experience. But with all the options out there, finding the best one for your body can feel overwhelming.

At Saalt, we like to acknowledge that everyone’s anatomy is uniquely different, which is why we offer two period disc sizes to get you one step closer to period bliss. This guide will break it all down for you—what a menstrual disc is, why you might want to try one, how cervix height matters, and how to find the best menstrual disc for your body and lifestyle.

Let’s dive in.

First Things First: Why a Menstrual Disc?

Let’s start with the basics.

The Saalt menstrual disc is a reusable period product that sits in the vaginal fornix (yep, it tucks up higher than a cup) and collects your menstrual flow rather than absorbing it. It’s completely suction-free, super comfy, and bonus—it can even be worn mess-free during sex.

That’s right: no messy surprises, no interference. Just you and your flow, getting along peacefully.

If you’ve ever felt like tampons or cups weren’t quite right for you, or if you’re tired of the monthly waste and want something more eco-friendly, a period disc could be a complete game changer.

Benefits of Using a Menstrual Disc

Okay, but what makes menstrual discs stand out from the crowd of other period products?

Here are just a few reasons why you might fall in love with a disc:

🌙 12 Hours of Protection

Yes, really. You can wear a menstrual disc for up to 12 hours at a time without having to empty it. That means fewer bathroom breaks and more freedom.

💪 Holds More Than a Tampon or Pad

Especially if you deal with heavy periods, clotting, PCOS, endometriosis, or a weaker pelvic floor, the capacity of a menstrual disc can be a lifesaver. It’s a solid option for anyone who’s been frustrated by frequently needing to change other products.

🌀 No Suction = Less Pressure

Unlike menstrual cups, which use suction to stay in place, discs rest comfortably in the vaginal fornix. This can mean less pressure, fewer cramps, and a more relaxed experience—especially for people with sensitivities or certain pelvic conditions.

💋 Can Be Worn During Sex

Yes, we said it again—because it’s that exciting. A well-fitted menstrual disc like the ones from Saalt can be worn during penetrative sex, giving you one more reason to feel comfortable and confident during your period.

🌎 Reusable for Up to 10 Years

Talk about sustainable. Investing in a high-quality menstrual disc means you can reduce waste, save money, and stop contributing to landfills every single month.

Now that you know the why, let’s move on to the which.

Saalt Menstrual Discs: Regular vs. Small

Saalt offers two disc options so you can find the best fit for your body and your flow. Both are crafted from 100% medical-grade silicone, include a removal notch for easier emptying, and are designed to be soft, ultra-comfortable, and reliable.

Let’s break them down.

🩸 Saalt Regular Disc

Best for:

• Mid to high cervix
  
  

• Heavier flow
  
  

• Folks who are used to using larger menstrual cups
  
  

Capacity:

50 mL — That’s about the equivalent of 6 regular tampons!

The Regular Disc is ideal if your period tends to be on the heavier side or if you’ve used menstrual cups before and had no issue with the larger sizes. It offers lots of room for your flow, so you can go longer between emptying it.

🌸 Saalt Small Disc

Best for:

• Lower cervix
  
  

• Light to moderate flow
  
  

• Beginners who are new to discs
  
  

Capacity:

30 mL — That’s about 4 regular tampons worth, which is similar to the Regular Saalt Cup’s capacity.

This disc is more petite and sits more comfortably for folks with a lower cervix or lighter flow. If you’re just starting out and unsure where to begin, this could be your perfect entry point.

How Your Cervix Height Can Determine Your Disc Size

This might surprise you, but cervix height plays a big role in determining which menstrual disc will be most comfortable and effective for you.

So what exactly is cervix height, and how can you figure it out?

🧬 What’s Cervix Height?

Your cervix is the lower part of your uterus, and its position changes slightly throughout your cycle. Some people naturally have low cervixes, meaning it sits closer to the vaginal opening, while others have mid or high cervixes.

🧪 How to Measure It

You can find your cervix by inserting a clean finger into your vaginal canal and feeling for a soft, rounded nub with a slight dimple in the center. The distance between your opening and your cervix will help you determine your height:

• Low Cervix: Can touch it with the first knuckle or less
  
  

• Mid Cervix: Second knuckle
  
  

• High Cervix: Need most or all of your finger to reach it
  
  

Low-Mid Cervix? Try a Smaller Disc

If your cervix is on the lower side, you’ll most likely find the most comfort with a smaller disc like the Saalt Small Disc. A larger disc might feel uncomfortable or push against the cervix in a way that doesn’t feel great.

Mid-High Cervix? Try a Regular Disc

If you have a mid to high cervix, a larger disc like the Saalt Regular Disc may be easier to insert and remove, and it’ll stay in place more securely.

Your Cervix Height Can Change

Yep—your cervix moves throughout your cycle, especially during ovulation or menstruation. If you find that your height seems to vary, the Saalt Disc Duo could be the best option, giving you both sizes to work with depending on your needs that day.

So, What’s the Best Menstrual Disc?

The truth is, the best menstrual disc is the one that fits your body, your lifestyle, and your flow.

Some people swear by a larger disc because it holds more and feels secure. Others prefer a smaller disc for easier insertion and a gentler fit. And plenty of folks discover that their favorite varies throughout their cycle—and that’s okay!

What really matters is that you find a disc that:

✅ Stays in place comfortably
✅ Gives you the protection you need
✅ Makes your period feel like less of a hassle
✅ Aligns with your values (like reducing waste or saving money)

Period Bliss, Your Way

Switching to a menstrual disc might feel like a big step, but it can open the door to a more comfortable, confident period experience. Discs give you freedom, flexibility, and a low-waste alternative to traditional period products.
