How to Stretch Safely: The 1mm Rule

Every pair we make is cut to the exact gauge you order. There is no adjustment afterwards, no shim, no returning a made-to-order pair because it sits a millimetre proud. That makes sizing — and the stretching that gets you there — the most important decision on this whole site, and the one most worth slowing down for.

This is the guide we give people who write in before ordering. It is not medical advice. It is what a bench that cuts plugs from 3mm to 25mm sees come back, and what the people whose lobes stayed healthy did differently.

The rule, in one line

Never jump more than one full millimetre at a time, wait six to eight weeks between jumps, and only ever stretch a lobe that is fully healed and comfortable at its current size.

That is the whole method. Everything below is detail on how to follow it and how to know when you have broken it.

Slow is permanent; fast is scar tissue. A stretch done gradually thickens the tissue as it widens, and that thickened tissue holds weight — it is what lets a healed lobe carry a solid gold pair at 16mm without thinning. A stretch forced through in a weekend tears instead, and torn tissue heals into scar: less elastic, thinner, and far less willing to move again later. The irony of rushing is that it costs you size in the long run.

Why one millimetre

Most standard gauge ladders step in roughly 1mm increments up to 10mm and then in fractions of an inch. Those steps exist because they are roughly what soft tissue tolerates at once. Below about 10mm, a 1mm jump is a large proportional change — going 4mm to 5mm is a 25% increase in diameter and a bigger increase again in circumference. That is why the lower rungs often feel harder than the big ones.

Above 10mm, 1mm is a smaller proportional step, and people start assuming they can take two. They can sometimes get away with it. The tissue at that point is thinner in cross-section than it was at 4mm — you are stretching the same amount of skin around a bigger circle — so what you get away with once is not the same as what is safe repeatedly.

Six to eight weeks, and how to know when it is actually eight

The wait is not arbitrary. After a stretch the lobe is inflamed, the tissue is thinner than it will settle at, and the piercing channel is remodelling. It looks normal again long before it is normal again.

A lobe is ready for the next jump when:

• There is no tenderness when you move the plug.
• Nothing weeps, crusts, or smells.
• The lobe is not red or noticeably warm.
• The plug moves freely with no pull.
• The lobe looks the same colour and thickness as the skin around it.

If any one of those is false, you are not at six weeks yet regardless of what the calendar says. Waiting longer costs nothing. There is no upper limit on how long you can hold at a size, and plenty of people stay at 10mm or 12mm permanently and are happier for it.

Taper vs. taping

There are two sane ways to move up a rung, and one that is not.

Tapers. A taper is a gradual cone you push through to guide the next size in. Used properly it is a sizing tool, not a stretching device: it is lubricated generously, inserted slowly, and never forced. A taper is only ever used to move one size. If a taper will not pass with steady, gentle pressure and a good lubricant, the lobe is not ready — the correct response is to remove it and wait weeks, not to push harder. Never wear a taper as jewellery; the weight sits wrong and the shape puts uneven pressure on one part of the channel.

Taping. Taping — wrapping thin layers of PTFE tape or bondage tape around your current plug and adding a layer every week or two — is the slowest and gentlest option, and for that reason it is what we suggest to anyone above roughly 10mm or anyone who has had a tear before. Each layer adds a fraction of a millimetre, so the tissue is never asked for a full millimetre in one moment. It is tedious. It is also the technique that produces the fewest problems.

Dead stretching — simply wearing the current size and waiting for the lobe to loosen on its own — is not a technique so much as patience, and it works surprisingly often after a long hold.

What is never acceptable: forcing a plug in without a taper, using a taper without lubricant, stretching in the shower because "it goes easier when warm" (heat and softened tissue mask pain, which is the only feedback you have), or moving up because a piece you want only comes in one size.

Blowouts and thinning — what to look for

A blowout is when the inside of the piercing channel is pushed out through the back of the lobe, leaving a raised lip of tissue behind the jewellery. It is a mechanical injury from too much, too fast, or from a flare being pulled through. It does not simply resolve; the usual fix is downsizing a size or two, wearing something light and smooth, and waiting months.

Thinning is the slower failure. The front wall of the lobe gradually loses substance until it is a fine band of tissue. There is a widely cited rule of thumb in the community that you want to keep at least about 2mm of tissue between the piercing and the edge of the lobe; below that, a tear becomes a matter of when. If your front wall is getting thin, you are done stretching, and the only way to gain size later is a surgical repair followed by a fresh, slow start.

When to stop

Stop, permanently or for a long time, if:

• The front or back wall of the lobe is thinning.
• You have had a blowout that has not fully resolved.
• The lobe aches under the weight of ordinary jewellery.
• The tissue feels cold, hard, or numb.
• You are stretching to reach a size for a specific piece rather than because the lobe is ready.

The last one is worth saying plainly, because we make the pieces: never stretch for jewellery. We will make almost anything in almost any size. Your lobes are not remakeable.

Measuring, and sizing for solid metal

Work from what you are actually wearing, not from what you were told you wore. Mislabelled acrylic is common, and half a millimetre of error becomes a whole rung of error at order time.

Two things people miss:

1. If you sit between two rungs, size down. A plug a touch loose is wearable and safe. A plug a touch large is a stretch you did not consent to, applied continuously.
2. Solid metal wears heavier than acrylic or silicone. A solid gold pair at your usual size will feel more present than the plastic you measured against, particularly in the first weeks after a jump. Rotate to something lighter on long days.

The true-size visualiser in our size guide draws each gauge at actual scale on screen, calibrated against a bank card, so you can hold your current plug against it before you commit. If you want the full conversion chart with what each size looks like in practice, read the mm-to-gauge chart.

mm to gauge, in short

Sizes between these rungs exist on our ladder too — the full chart, including the approximate conversions, is in the size guide.

Before you commission

Every PLUGS+ pair is cast, set and hand-finished to order and ships in 4–6 weeks, so sizes are final. If you are between rungs, or mid-way through a stretch and unsure where you will land, write before you buy rather than after — we would far rather have the conversation up front. If you are settled and ready, the catalogue runs 3mm to 25mm across the shop, and the solid gold collection is the usual starting point for a first heavy pair.
