A navel ring is the one piercing where the jewellery choice has the most consequences. The bar sits under a waistband, bends when you sit, and carries the weight of whatever hangs from it. Get the length or the gauge wrong and it either presses or migrates. This guide covers what to measure before you buy.
The three measurements that matter
| Measurement | Typical range | What happens if it is wrong |
|---|---|---|
| Bar length | 6–12 mm | Too short: presses and digs. Too long: catches and tilts, which encourages migration |
| Bar thickness (gauge) | 1.6 mm / 14G | Too thin: migration risk in soft tissue |
| Top and bottom ends | 4–8 mm | Too wide: rubs on clothing and sits at an angle |
Most navel piercings are done at 14G, which is 1.6 mm. If you were pierced at 14G, stay at 14G. A thinner bar in a navel is the single most common cause of a piercing that slowly moves.
Bar length: the number to get right
Bar length is measured along the bar between the two ends, not the total height of the piece including the decorative fronts. A comfortable healed navel ring leaves a small amount of visible bar, not a lot.
- 10 mm is the most common adult size and what most of our navel rings use.
- 8 mm suits a shallow navel or someone who has downsized after healing.
- 12 mm and longer is usually for the initial piercing, when swelling needs room.
If you were pierced recently, do not downsize on your own. The piercer who did it will tell you when and to what length.
Top and bottom ends
The bottom end is the piece that shows, so it gets chosen first. The top end is the one you feel. A top bead wider than the skin can accommodate sits at an angle and rubs the inside of the navel. On our listings the size diagram shows both: for example 5 mm top, 10 mm bar, 1.6 mm thickness, 9.3 x 9.3 mm floral setting tells you the top is small, the bar is standard and the decorative part is nearly a centimetre across.
Choosing a style
Classic ball or gem
A single stone on a plain curved barbell. The safest choice for a first change, because there is nothing to catch and the weight is centred. It also reads cleanest under clothing.
Charms and dangles
Butterfly, floral, scorpion and charm styles hang below the bar. They look best in a shallow navel with a visible rim, because a deep navel hides the detail. The trade-off is snagging: anything that hangs will catch on a waistband eventually.
Hinged and clicker styles
Some navel designs use a clicker format rather than a barbell. Check the fitting method on the listing before ordering, because a clicker and a curved barbell are not interchangeable in the same piercing.
Our belly button ring collection groups these by style, and every listing carries a size diagram with bar length, thickness and setting dimensions.
Gold-tone or silver-tone
Both are titanium. The gold is a PVD coating over the metal, not solid gold, so it will not tarnish like plated brass but can wear at high-friction points over years. Silver-tone is the natural polished finish and shows wear less. Neither affects how the piece fits.
When to replace a navel ring
- The coating has worn through at a contact point
- The thread no longer holds the top securely
- The bar length no longer matches the piercing after swelling has settled
- The decoration has bent or lost stones
Before replacing, check that you are ordering the same gauge and a bar length within 2 mm of the one you wear now. If you are changing both gauge and length at once and the piercing is healed, change one at a time.
