The Dual Sizing System That Ends Menstrual Disc "Fit Guesswork" for Good.
Here is something nobody tells you before you buy your first reusable:
You are asked to pick a size before you are allowed to find out which one is right.
One box arrives. One diameter inside it. You measured with a finger in the shower, you read a chart built from averages, and then you paid forty dollars to discover whether the guess was correct.
If it was wrong, there is no second size waiting in the bathroom cabinet. There is a return window, an email, and a product you have already opened.
So most women do not reorder. They put it in a drawer and go back to tampons.
That is not a product failure. That is a purchasing model that made you bet before you had the information.
Here are the 7 reasons women are moving to a kit that ships both sizes together.
1. The Chart Measured Your Cervix. It Never Measured Your Cycle.
Every sizing guide asks the same question. How high does your cervix sit on day two, measured with one finger, in the shower.
It is a reasonable question. It is also a single reading, taken on a single day, of a body that does not hold still.
Cervix height moves through a period. It sits lower at the start and rides higher as the days pass. A number you took on Tuesday is not the number that applies on Friday.
So the chart was not lying to you. It was answering a question too narrow to decide a purchase.
2. You Bought the Other Size. Same Forty Dollars, Same Drawer.
The second purchase is the one that ends it for most women.
Small felt loose, so you tried large. Large felt like too much, so you went back down. Somewhere in there you stopped telling people you were still trying.
Two orders, two guesses, eighty dollars, and still no way to compare the two side by side on the same day of the same period.
That is the part that makes it feel personal. You were never given the one thing that would have settled it: both options, at the same time, on your own body.
3. Fit Is Not One Number. It Is a Range.
A heavy day and a light day are not the same fit problem. Neither are the years before a birth and the years after one.
Women who use reusables for a long time work this out eventually. They keep two, and they choose in the morning based on the day they are having.
The people who are happiest with a disc are almost never the ones who found the perfect size. They are the ones who stopped needing a perfect size.
You guess before you know
Wrong size means a return
No comparison on the same cycle
Second try costs another order
You test on day one
Wrong size means reach for the other
Compare within one period
Second try costs nothing
4. Both Sizes Are in the Box, So Day One Is a Test, Not a Bet
Every Routiné Kit ships with a medium and a large together. Not as an upsell, not as a second order. In the first box, at one price.
That single change moves the fit decision from before the purchase to after it. You are no longer predicting which size suits you. You are checking.
- No size to select at checkout. There is no dropdown, so there is nothing to get wrong.
- Both on hand from the first cycle. If one is not right, the other is already in the bathroom.
- One charge. The second size is not a second purchase, and there is nothing to reorder later.
Free shipping on all orders and a free anatomical guide with the Kit. With 30 days to return it, there is nothing to lose.

5. Start With the Medium. The Large Is Already in Your Bathroom.
The instruction that comes with the Kit is one line long. Start with the medium.
If it sits well, you are done, and you never open the other pouch. If something feels off, you take it out, breathe, and reach for the large. That is a five minute correction, not a five day one.
Most women settle within the first cycle. Some use the medium on lighter days and the large on heavier ones and never pick a permanent answer at all. Both outcomes are normal, and both were already paid for.
6. What Changes When the Size Question Disappears
Nobody quits reusables because of one uncomfortable hour. They quit because of what that hour implies: that they picked wrong, that the money is gone, and that finding out costs another order.
Take the guess away and the whole calculation changes. A first try that does not sit right stops being a verdict and becomes information.
You are not evaluating whether your body suits the product. You are choosing between two things you already own.

"I had already wasted money on one that did not fit, so I was expecting to waste more. Having both in the box meant I found my size on the first evening instead of the third month."
"I started with the medium, swapped to the large on my heavy days, and now I just use whichever suits the day. I did not realise that was allowed."
"The thing that sold me was not having to pick at checkout. I have guessed wrong on this before and I did not want to do it again."
