Which Pessary Storage Case Size Do You Need? Small (Sizes 0–3) vs Large (Sizes 4–8)

Pick the case that matches the size of the ring pessary you wear. The Small case fits ring pessary sizes 0, 1, 2 and 3. The Large case fits sizes 4, 5, 6, 7 and 8. If you are not sure of your size, or you use two sizes on either side of 3 and 4, choose the Large case.

That is the short answer. Below, we explain how to find your size, why the right fit matters, and a few simple tips for everyday use. If you are wondering whether you need a case at all, our article on why every ring pessary user needs a storage case covers that.

The quick size guide

Your ring pessary size Case to choose
0, 1, 2 or 3 Small
4, 5, 6, 7 or 8 Large
Not sure yet, still being fitted Large
You use two sizes, such as a 3 and a 4 Large

Both cases are the same price, so the choice is only about fit.

How do I find my pessary size?

Your pessary size is chosen by your doctor or nurse during your fitting. It is not something you need to measure yourself. Here are a few easy places to look:

  • The pessary box or package. The size number is usually printed on the label.
  • Your order history. If you bought your pessary online, the size is listed on your order or receipt.
  • The pessary itself. Some pessaries have the size stamped or printed on the ring.
  • Your clinic. Call your doctor's office and ask. They keep a record of the size they fitted.

Please do not guess or change your pessary size on your own. If your pessary feels uncomfortable, slips, or makes it hard to pass urine, talk to your doctor. A size change should always come from your care team.

Why the right case size matters

It may seem like any box would do. But the fit of the case makes a real difference to how your pessary is kept between wears.

If the case is too big

Your ring has room to slide and rattle around, especially in a purse or suitcase. That movement can rub the surface and is not ideal for keeping it clean and in good shape.

If the case is too small

The silicone gets squeezed against the lid when you close it. Over time, pressing on the ring like this can bend it out of its proper shape.

When the size is right

The ring sits comfortably, does not move around much, and keeps its shape. That is exactly what you want between wears.

What if I am in between, or still being fitted?

Many women try more than one size before finding the one that feels right. Others keep two sizes at home because their doctor suggested it. If your sizes fall on both sides of the line, such as a 3 and a 4, the Large case is the better pick. It holds the smaller ring with room to spare and still fits the bigger one.

The same goes if you are just starting out and your size is not settled yet. Choosing Large means you will not have to buy a second case if your size goes up.

Do I need two cases?

Some women like to have two cases. Here are a few times when a second case can be handy:

  • You keep a backup pessary. A spare ring stays clean and ready in its own case, in a purse or travel bag.
  • You travel often. One case lives at home, and one stays packed in your travel bag.
  • You use two different sizes. One case for each makes it easy to tell them apart.

Simple tips for using your case

  • Clean your pessary first. Follow the cleaning steps your doctor or nurse gave you, and the instructions that came with your pessary.
  • Let things dry. Put your pessary away only after it is dry.
  • Wash the case too. Use warm water and a mild, unscented soap. Let it air dry before use.
  • Keep it in a safe spot. A drawer or shelf away from the toilet and sink works well at home.
  • Bring it to your check-ups. It is an easy, clean way to carry your pessary to a fitting appointment.

Your doctor or nurse knows your situation best. Always follow their advice on how often to remove, clean and wear your pessary.
