# Complete Guide to Nose Ring Sizes and Gauges

Buying a nose pin or ring means getting three things right: the gauge (the thickness of the post), the diameter (for hoops and rings), and the backing (how it stays in place). Get them right, and the piece sits comfortably and securely; get them wrong, and it won’t fit your piercing. This guide covers all three.

## What is gauge, and which do I need?

Gauge is the thickness of the post or wire that passes through your piercing. It works backwards from what you’d expect; a lower gauge number means a thicker post. These are the gauges you’ll come across:

| **Gauge** | **Post diameter** | **Most common for** | **Notes** |
| --- | --- | --- | --- |
| 16G | 1.2mm | Stretched piercings, septum rings | Less common for standard nostril piercings |
| 18G | 1.0mm | Standard UK nostril piercing | The most common gauge — most UK piercers use this |
| 20G | 0.8mm | Fine nostril piercings, sensitive noses | Popular for smaller noses or a delicate look |
| 22G | 0.6mm | Very fine, delicate piercings | Less common — check with your piercer before ordering |

 

The most important rule: your jewellery gauge should match the gauge your piercing was made at. Too thick and it won’t pass through; too thin and the piercing can start to shrink around it.

## What about diameter?

Diameter applies to hoops and nose rings, not studs;  it’s the width of the ring’s circle. Most nose rings sit comfortably between 6mm and 8mm: 6mm to 7mm for a snug, close fit against the nostril, and 8mm for a looser, more visible hoop. If you’re between sizes, our team can help you judge it in person.

## What backing type should I choose?

The backing is just as important as the gauge; it’s what keeps the pin in place. Each type suits a different wearer:

| **Backing type** | **How it works** | **Best for** | **Security** |
| --- | --- | --- | --- |
| Screw back | The post is threaded and screws into a small nut inside the nostril | Daily wear and active lifestyles | Highest |
| L-shaped | The post bends at 90° and tucks inside the nostril | Easy on and off; less frequent wear | Medium |
| Straight pin | A traditional straight post, bent to shape after insertion | Traditional Indian fitting, experienced wearers | Lower (needs skill) |
| Flat back (labret) | A flat disc sits inside the nostril | Sensitive or healing piercings | High |

 

## How do I choose the right size?

If you’re not sure of your gauge, 18G is the safest default for most UK nostril piercings. If your piercing was done by a professional UK piercer, the surest route is to ask them which gauge they used;  that is the size you need. Still unsure? Start with 18G, or visit our Green Street showroom, where our team can help you find the right gauge, diameter and backing in person.
