18G vs 20G Nose Ring in the UK: Which Gauge Is Better?

What does gauge actually mean on a nose ring?

Gauge refers to the thickness of the metal wire that forms the ring. It's the number you'll see written as "18G", "20G" or "16G" on a product listing.

The gauge system is counter-intuitive: a smaller gauge number means a thicker wire, and a larger gauge number means a thinner wire. So a 16G ring is thicker than an 18G, which is thicker than a 20G.

Getting the gauge right matters because it affects three things at once:

Fit. The gauge has to match the size of your existing piercing channel. If it's too thick, the ring won't go in. If it's too thin, the jewellery will move around more than it should.

Comfort. A well-matched gauge sits stable in the piercing and barely registers during the day. A mismatched gauge can feel loose, tight, or noticeable in the wrong way.

Look. Thicker wire (18G) reads as slightly bolder and more substantial. Thinner wire (20G) reads as finer and more minimal.

What's the difference between 18G and 20G?

The two gauges are only 0.2mm apart, but that small difference changes how the jewellery sits, feels, and looks.

Neither is "better" in absolute terms — they suit different preferences and different piercings. The right one is the gauge that matches the piercing you already have.

Is 18G or 20G better for a healed nostril piercing?

Both 18G and 20G work well for healed nostril piercings in the UK. The best choice is not about which gauge is universally better — it's about matching your existing piercing channel and your preferred look.

First, check your existing gauge

If you already wear a nose ring that fits comfortably, your safest move is to order the same gauge again. Forcing a thicker gauge through a piercing made for a thinner one can damage the channel; wearing a thinner gauge in a larger piercing can let the channel shrink over time.

Choose 18G if you want a slightly bolder, more stable look

If your piercing fits 18G and you prefer a hoop with a little more visual weight, 18G is a good match. The thicker wire moves less during the day, which some wearers prefer for everyday comfort.

Choose 20G if you want a finer, more delicate look

If your piercing fits 20G and you prefer a refined, minimal appearance, 20G is the better choice. It suits people who want barely-there styling or who layer multiple piercings together.

Is 18G the standard nose ring size in the UK?

Many UK nostril piercings are 18G or 20G, depending on the studio, jewellery style and piercing history. 18G is commonly used for a slightly more stable fit, while 20G is common for finer jewellery.

If you had your piercing done professionally, your piercer will know the exact gauge they used. That's the easiest way to confirm your size before buying jewellery online.

How do I know which gauge I already wear?

If you already wear a nose ring that fits comfortably, there are three reliable ways to confirm the gauge.

1. Check the product listing or packaging. The gauge is almost always written on the original product page, packaging slip, or receipt. Look for "18G", "20G", or the metric equivalent (1.0mm or 0.8mm).

2. Ask your piercer. If you had the piercing done at a UK studio, they'll have a record of the jewellery used. A quick message or visit is the most accurate option.

3. Measure with a caliper. A small digital caliper (under £10 online) measures wire thickness precisely. Lay the wire of an existing ring between the jaws and read off the millimetres.

Does gauge change how a nose ring looks?

Both gauges can look elegant in solid 14ct gold. The finish, style (seamless vs segment), and inner diameter all matter as much as the gauge itself.

Which gauge feels more comfortable?

A healed piercing should feel comfortable in either gauge — provided the gauge matches the piercing. Comfort isn't really about 18G vs 20G in the abstract; it's about whether the ring fits the channel you already have.

That said, there are general tendencies:

18G often feels more stable. The slightly thicker wire moves less during the day, which some wearers prefer for active lifestyles or for piercings that have ever had irritation issues in the past.

20G often feels lighter. Some wearers genuinely forget it's there. If you find jewellery distracting or sensitive to changes in temperature, the lighter weight of 20G can be more comfortable.

What inner diameter should I choose with 18G or 20G?

Gauge and inner diameter are two separate measurements, and you need to get both right for the ring to fit and look the way you want.

Gauge tells you how thick the wire is (18G or 20G). Inner diameter tells you how wide the hoop is across the inside — usually 6mm, 7mm, 8mm, 9mm or 10mm for nostril piercings.

A ring can have the right gauge but the wrong diameter, and it will still fit badly — either floating awkwardly off the nostril or sitting too tight against the skin. Most UK buyers also need a 7mm or 8mm inner diameter for healed nostrils, not just the right gauge.

Can I switch from 18G to 20G (or back)?

This is one of the most common UK buyer questions. The short answer is: match the gauge you already wear unless a piercer confirms you can safely change size. Use this table as a quick reference.

Which gauge should you buy from Stepoy?

We make 14k solid gold seamless nose hoops specifically for healed UK nostril piercings, in both 18G and 20G. Here's how we'd recommend choosing.

Why 14ct solid gold works well in both gauges

Whichever gauge you choose, the material matters as much as the size. 14ct solid gold is a strong fit for healed nostril piercings because it's hypoallergenic when alloyed correctly, holds its shape in fine wire, and keeps its colour for years.

More durable than plated. Plated jewellery wears down over time, especially inside a piercing channel where the gold layer rubs against skin. Solid 14ct gold doesn't have a coating to lose.

Holds up in fine gauges. Higher carat options (18ct, 22ct) are softer and more easily bent in 20G wire. 14ct is hard enough to keep its shape in a delicate hoop without feeling brittle.

Clean finish for daily use. A polished seamless 14ct hoop sits flush against the skin without rough edges or visible joins — equally clean in 18G or 20G.
