You are already considering the Saalt Disc. The decision now is narrower: will Small stay secure enough, or will Regular fit better without creating pressure or making removal harder?
This guide is built around that purchase decision. It does not try to explain every menstrual-disc feature. It focuses on fit, leakage, removal, capacity, return risk, and the current buying issues that can actually change which size you choose.
Quick Answer
Start with fit, then use flow as a secondary factor. Saalt lists Small at 56 mm / 30 mL and Regular at 66 mm / 50 mL. Small is positioned for a lower cervix and lighter-to-normal flow; Regular for a higher cervix, normal-to-heavy flow, and users who have trouble keeping discs inserted. [1]
Saalt Disc
One reusable disc sold in two sizes: Small 56 mm / 30 mL and Regular 66 mm / 50 mL. Both are currently listed at $35. [1]
- Small: lower cervix; lighter-to-normal flow.
- Regular: higher cervix; normal-to-heavy flow; more capacity.
- Important limitation: size guidance is a starting point, not a fit guarantee.
What Does the Size Difference Actually Mean?
The 10 mm diameter difference matters more than it may look on a product page. Small is 56 mm across and holds 30 mL; Regular is 66 mm and holds 50 mL. Saalt describes both as reusable medical-grade silicone discs and markets them for up to 12 hours of wear. [1]
Small makes more sense when…
You have a lower cervix, lighter-to-normal flow, or a larger disc creates pressure. Its smaller diameter also means less capacity.
Regular makes more sense when…
You have a higher cervix, want more capacity, or smaller discs have trouble staying tucked. The trade-off is that a larger diameter can be less comfortable or harder to remove for some users.
Capacity should not override anatomy. Regular’s extra 20 mL only helps if the larger diameter stays comfortable and properly positioned.
What If Small Feels Comfortable but Keeps Leaking or Untucking?
This is where comfort and stability separate. Saalt’s size guidance directs users who have trouble keeping discs inserted toward Regular. [1]
Period Nirvana’s independent review found Small easier to insert and remove, but it could become untucked during toilet use, while Regular stayed more secure for that reviewer. [2]
Decision meaning: if Small feels fine but repeatedly shifts, loses its tuck, or leaks during movement after placement has been checked, the smaller diameter may be contributing to the problem.
What If Regular Feels Secure but Too Large?
Regular solves the opposite problem: more diameter and more capacity. In Period Nirvana’s review, Regular gave a secure, leak-free fit but could sometimes feel lodged behind the pubic bone and require more manipulation during removal. [2]
Decision meaning: if Regular stays secure but creates persistent pressure, feels difficult to tuck, or turns removal into a recurring struggle, the extra capacity may not justify the fit penalty.
Does Leaking Automatically Mean You Need the Other Size?
No. Saalt’s troubleshooting guidance lists several possible causes, including placement, fit, capacity, and whether the rim remains tucked behind the pubic bone. [3]
That distinction matters because a size change will not fix a placement problem. There is also a difference between ordinary leakage and self-emptying during toilet use, where pelvic-floor movement can temporarily shift the rim.
If leaking happens because the disc will not stay tucked, size becomes more relevant. If it stays secure but leaks only after becoming very full, capacity may matter more. The symptom should guide the next step.
What If Removal Is Your Biggest Concern?
Saalt includes a finger notch and presents it as a removal aid. [1] That feature can help, but it does not guarantee the notch will always be facing the easiest direction to reach.
Period Nirvana reported that Small was generally easier to remove, while Regular occasionally needed more manipulation; the notch could also rotate. [2]
If removal anxiety matters more than capacity, reach and comfort deserve more weight than the larger size’s extra 20 mL.
What If You Choose the Wrong Size?
Saalt’s current 90-Day Bliss Guarantee reduces some purchase risk, but the refund detail matters. Unused, unopened items can qualify for a refund; opened products that do not work out generally qualify for store credit. Original shipping and import fees are not refunded. [4]
So the policy can help you switch sizes, but it is not the same as a guaranteed cash refund after trying an opened disc.
Are There Any Current Buying Concerns Beyond Fit?
Saalt currently publishes an estimate of 2–4 business days for processing and shipping plus 3–10 business days for domestic delivery. [5]
Recent 2026 Reddit and Trustpilot reports describe some orders taking longer and some support responses being slow. [6] [7] These reports are anecdotal and do not establish a brand-wide delay rate, but if you need the disc by a specific date, treat the published window as an estimate rather than a guarantee.
Pros
Cons
- Fit is anatomy-dependent; the size chart cannot guarantee comfort or leak-free use.
- Small may be less stable for some users; Regular can be harder to remove for some users. [2]
- Opened products generally move into store-credit rather than cash-refund territory. [4]
- Recent 2026 buyers have reported some shipping and support delays. [6] [7]
Final Decision: Small or Regular?
Choose Small when the lower diameter better matches your cervix height and comfort. Choose Regular when you need more stability or capacity and the larger diameter remains comfortable.
If Small repeatedly loses position, Regular may solve the stability problem. If Regular stays secure but causes pressure or difficult removal, Small may be the better fit. The useful rule is simple: fit first, capacity second.

FAQs
Is Small or Regular better for a first-time disc user?
Saalt positions Regular for many new disc users, but that does not override cervix height or comfort. A lower cervix can still make Small the more appropriate starting point. [1]
Can Saalt Disc auto-dump?
Saalt discusses self-emptying as part of disc use and troubleshooting. If the disc also untucks or leaks during normal movement, fit and placement deserve separate attention. [3]
Can I return an opened Saalt Disc?
Opened products that do not work out generally qualify for store credit rather than a refund to the original payment method. [4]
