You are choosing between 8mm and 12mm in 16G or 18G
This guide is for healed septum piercings only
A septum piercing passes through the thin tissue between the nostrils (the columella or "sweet spot") and needs time to settle before a ring feels comfortable. Switching too early can cause irritation, pressure, or prolonged healing. If your septum is still sore, swollen, crusting, or producing discharge, it is too early to change jewellery.
Quick answer
For many healed septum piercings, 10mm is the most balanced starting point.
8mm for a very snug fit. 9mm for a close, subtle look. 11mm for a relaxed hang. 12mm if your anatomy needs the boldest, most visible option.
16G is the standard septum gauge, while 18G is a finer option for healed piercings.

Not sure between two sizes?
Choose the larger one. A septum ring that is slightly bigger will hang more comfortably than one that pinches or presses against the tissue.

Should you choose 16G or 18G?

Gauge is the thickness of the wire, not the size of the ring. For septum rings, 16G is the standard gauge, while 18G is a finer option for healed piercings.

GaugeThicknessBest forNotes
16G Standard septum gauge1.2mmStandard septum fitThe most familiar and commonly recommended gauge
18G1.0mmFiner healed-piercing lookSlightly lighter and more delicate in appearance

If your septum was originally pierced at 16G, an 18G ring may still fit once healed, but it can feel lighter and sit differently than what you are used to.

When can you wear a septum ring?

A septum piercing goes through soft tissue and usually heals faster than cartilage piercings, but it still needs time to fully settle before a ring feels comfortable. Switching too early can cause irritation or delay healing.

Before changing jewellery, make sure your septum shows no pain, swelling, crusting, or discharge. If it still feels tender or reactive, wait longer and ask your piercer to confirm healing.

Why does my septum ring feel tight?

It feels tight or presses into the septum

The diameter is too small. Move up one size, for example from 8mm to 9mm or from 10mm to 11mm.

It hangs lower than expected

The diameter may be larger than your anatomy needs. That is not always wrong — some people prefer a relaxed hang — but if you want a closer fit, try one size smaller.

It flips up or moves around

This can happen with a ring that is too large or too light for your nose. A slightly smaller diameter or a 16G gauge (instead of 18G) can help the ring sit more securely.

How do I measure my septum for a ring?

If you already own a septum ring that fits well, place it flat on a surface and measure straight across the inside opening in millimetres. That measurement is the inner diameter you should order.

If you do not have a ring to measure, the most reliable approach is to ask your piercer. They can assess your anatomy and recommend the best inner diameter. If you prefer to estimate at home, measure the distance from the piercing hole to the bottom of the nose — this gives you a rough guide, but anatomy can make it tricky to measure accurately on your own.

Why choose 14K solid gold?

A healed septum often does best with high-quality materials, especially if you want a ring you can wear daily. 14K solid gold is a strong choice because it will not peel or flake like plated jewellery.

For many customers, solid gold offers the best balance of beauty, durability, and everyday comfort. It is a strong choice if you want a fine ring you can keep in regularly.

Frequently asked questions

What size septum ring should I buy?
For many healed septum piercings, 8mm is the most balanced starting point. Choose 8mm or 9mm for a snug fit, 9mm for a relaxed fit, and 10mm if your anatomy needs a bolder, more visible look.
Is 8mm too small for a septum ring?
Not always. 8mm can work well for petite noses or high septum placements, especially if you want a very snug, discreet fit.
Is 9mm a good septum ring size?
Yes. 9mm gives a close, subtle look. It is a good choice if 8mm feels too tight but 10mm feels slightly too open.
Is 10mm the best septum ring size?
For many people, yes. It is often the most balanced and comfortable starting point for a healed septum.
Is 11mm too big for a septum ring?
Not necessarily. 11mm offers a slightly relaxed hang. It is a good choice if you want a little more visibility without going to the largest size.
Is 12mm too big for a septum ring?
It depends on your anatomy. 12mm is a valid choice for larger noses or if you want a bold, visible ring with a relaxed hang.
What gauge is a septum ring?
The most common septum gauge is 16G. Some healed septums can also wear 18G for a finer look.
Is 16G the standard septum gauge?
Yes. 16G is the most familiar and commonly recommended gauge for septum piercings and septum rings.
Should I choose 16G or 18G for a septum ring?
Choose 16G for the standard fit. Choose 18G if you want a finer, more delicate look and your healed piercing already accommodates it comfortably.
Can I wear a ring in a healed septum piercing?
Yes, as long as the piercing is fully healed and no longer painful, swollen, or irritated.
When can I change my septum to a ring?
Only once it is fully healed. If you are unsure, ask your piercer before changing jewellery.
How do I measure my septum for a ring?
Measure the inside diameter of a ring that already fits you well, or ask your piercer to assess your anatomy.
Why does my septum ring feel tight?
The diameter is probably too small for your anatomy. Moving up one size usually solves the problem.
Why does my septum ring flip up or move around?
The ring may be too large or too light. Try a slightly smaller diameter or a 16G gauge for more stability.
Is 14K solid gold good for a septum ring?
Yes. It is a strong long-term material choice for a healed septum piercing.
