The most common question from women new to yoni eggs: which size do I start with? The short answer surprises almost everyone — you start with the largest one. Here is why, how to progress, and how to tell when you are ready to move down.

First, what a yoni egg actually is

A yoni egg — also sold as a yoni stone, jade egg or Kegel egg — is a smooth, polished, egg-shaped piece of crystal used as a focus for pelvic-floor exercises. The practice is simple: the egg gives your pelvic-floor muscles something to gently engage around, so you can actually feel a contraction you would otherwise be guessing at. That feedback is the entire point. It is the same reason a physiotherapist will put a hand on a muscle you are trying to isolate.

It is an exercise aid and a mindfulness object, nothing more clinical than that. Nephrite jade is the traditional stone, which is why “jade egg” and “yoni egg” are so often used to mean the same thing.

The three sizes at a glance

Sizes vary a little between suppliers because every egg is cut from natural stone, so treat these as close approximations rather than exact specifications. What matters far more than the millimetre is the order you use them in.

Which size should a beginner start with?

Counter-intuitively, start with the largest egg. It is easier to feel, easier to hold with gentle muscle engagement, and easier to keep comfortably in place while you learn. A very small egg is harder for a beginner to sense and control.

Why bigger is genuinely easier at the start

This trips people up because it runs against the instinct that says smaller must mean gentler. Think about the mechanics instead. A larger egg has more surface in contact with the muscle wall, so there is more for your pelvic floor to grip and far more sensation to work with. A small egg gives you less to hold and demands finer, more isolated control — which is a skill you build, not one you begin with.

There is a second reason, and it is the practical one: confidence. A beginner who starts small and cannot feel anything usually concludes the practice is not working and stops. A beginner who starts large gets clear feedback in the first session. Starting easy is not a compromise here; it is the fast route.

Your first two weeks: a simple starting routine

You do not need a complicated programme. A realistic beginning looks like this:

• Days 1–3. Wash the egg, warm it in your hands, and simply hold it in place for 10–15 minutes while lying down or moving gently around the house. No squeezing yet — just get used to the sensation.
• Days 4–10. Add slow, deliberate contractions: engage for a count of three, release fully for a count of three, ten times. The release matters as much as the squeeze. A pelvic floor that never relaxes is not a strong one.
• Days 11–14. Keep the same routine and add a few contractions while standing, which is harder than lying down.

Fifteen or twenty minutes a day is plenty. Longer is not better, and wearing an egg overnight or for hours at a stretch is not recommended by anyone sensible.

How to know you are ready for the next size down

Move to the medium egg when the large one feels genuinely easy — when you can hold it, contract around it, and stand and walk without thinking about it. As your pelvic-floor strength grows, move to medium, then small. The smaller the egg, the more control it asks of you. There is no rush and no wrong pace, and there is no prize for reaching the smallest size. Plenty of women stay on medium indefinitely because that is where they feel the work.

Drilled or undrilled?

A drilled egg has a hole to thread unwaxed cotton or dental floss for easy removal — reassuring for beginners. An undrilled egg is removed with your own muscles. If in doubt, start drilled. Replace the thread every single use; it is a consumable, not part of the egg.

Five sizing mistakes worth avoiding

• Starting small to be cautious. The most common mistake, and the one that makes people give up.
• Rushing down a size. If you are still concentrating hard to hold the large egg, you are not ready for the medium.
• Wearing it too long. Fifteen to twenty minutes of focused practice beats three distracted hours.
• Forcing anything. Insertion should be easy and comfortable. If it is not, stop.
• Using a chipped egg. Any crack, chip or rough patch means retire it, whatever the size.

A word about pelvic-floor health

People search for yoni stones for the pelvic floor, and it is worth being straight about what this is and is not. A yoni egg is a way of making Kegel exercises easier to feel and easier to stick with. It is not a treatment, and weighted insertables are not right for everybody — some pelvic-health physiotherapists prefer unweighted exercises, particularly where there is pain or an overactive pelvic floor.

If you are dealing with prolapse, incontinence, pelvic pain, recovery after birth or surgery, or anything that has you worried, see a pelvic-health physiotherapist or your doctor first. They can assess what is actually going on and tell you whether this kind of practice suits you. That is a better outcome than guessing, and no crystal is a substitute for it.

Common questions

Can I use a yoni egg if I have never done Kegels before?

Yes — that is the usual starting point, and the egg is there precisely to make the movement easier to feel. Begin with the large size and the routine above.

How do I know if the egg is too small for me?

If you can barely sense it, or you have to concentrate hard to keep track of where it is, it is too small for where you are now. Go back up a size; nothing is lost.

Is it normal to feel nothing at first?

Fairly common in the first session or two, and usually a sign the egg is too small or that you are tensing your glutes and abdomen instead of the pelvic floor. Relax everything else and try again lying down.

Can I walk around with it in?

Once holding it is comfortable, yes, for short periods. Build up to it rather than starting there, and take it out if you feel any dragging or discomfort.

Do I need all three sizes?

Not strictly, but a set is the practical choice because you will outgrow the large one and the progression is the whole method.

Our recommendation

The easiest start is a set of all three sizes — begin with the large and keep the others ready. Nephrite jade is the traditional, durable first stone, and it is the most forgiving to look after.

A yoni egg is a wellness and pelvic-floor (Kegel) exercise tool, not a medical device. If you are pregnant, have an IUD, an infection, or any concern, please check with your healthcare provider first, and always listen to your body.
