Size Guide
The right earring size is key to comfortable wear, proper healing, and an aesthetic result. Learn how to measure gauge, bar length, and ring diameter for each type of piercing.
What do earring dimensions mean?
Before choosing a size, understand four key concepts. Most problems with earring selection arise from confusing length with thickness or measuring a ring from the outside instead of the inside.
The diameter of the earring bar measured in millimeters. The thicker the earring, the higher the value in mm. Example: 0.8 mm (thin, earlobe), 1.2 mm (medium, cartilage), 1.6 mm (thick, navel).
The distance measured between the ornaments, excluding the balls themselves. For fresh piercings, longer earrings are chosen (+2–4 mm) due to swelling during healing.
The internal diameter of the ring measured from edge to edge inside the ring, excluding material thickness. The smaller the diameter, the tighter the ring.
The higher the gauge number, the thinner the earring. 20g = 0.8 mm, 16g = 1.2 mm, 14g = 1.6 mm. In Poland, we use millimeters – always check what the given value means.
Gauge is an American measurement system. In Poland and Europe, we use millimeters. When ordering an earring, always check whether the given value is gauge (e.g., 16g) or millimeters (e.g., 1.2 mm) – these are different notations but can refer to the same earring.

Earring types and measurement rules
Each earring type is measured differently. Learn the instructions for the three most popular forms and avoid common mistakes when ordering.
Labret
A bar with a flat disc (flat back) on one side and a screw-on ornament on the other. Most popular for ear cartilage, lip, and nose piercings. A barbell has balls on both ends (tongue, nipples).
A = Bar thickness (gauge) | B = Length between ornaments
Segment Ring, BCR, Clicker
Available in variants: Segment Ring, BCR, Seamless Ring, Clicker. Popular for septum, daith, and nose.
Note: Rings are not recommended for fresh piercings – start with a labret and change after healing.
A = Bar thickness | B = Internal diameter
Banana
Standard shape for navel, eyebrow, rook, and intimate piercings. The anatomical shape naturally adapts to the body.
Most common mistake: Banana length is measured in a straight line, NOT along the curve!
A = Bar thickness | B = Length in a straight line
Ear piercing sizes
The ear offers the most piercing possibilities – from classic lobe to elaborate cartilage compositions. Each location requires appropriate earring thickness and length.
- Earlobe: 6–8 weeks
- Cartilage (helix, tragus, conch, daith, rook): 6–12 months
For fresh cartilage piercings, use earrings that are 2 mm longer than specified in the table. After 4–8 weeks, downsize to the standard size.
| Piercing type | Bar thickness | Recommended length | Earring type |
|---|---|---|---|
| Earlobe | 0.8 mm20g | 6–8 mm | Labret, stud |
| Tragus | 1.2 mm16g | 6–8 mm | Labret (flat back) |
| Helix | 1.0 mm18g | 6–8 mm | Labret, ring (after healing) |
| Anti-helix (Forward Helix) | 1.0 mm18g | 8–10 mm | Labret |
| Conch | 1.0 mm18g | 8–10 mm | Labret or large ring |
| Daith | 1.0 mm18g | Ø 8–10 mm | Ring, clicker |
| Rook | 1.0 mm18g | 8–10 mm | Curved barbell |
| Industrial (Scaffold) | 1.2 mm16g | 35–38 mm | Long barbell |
Nose and eyebrow piercing sizes
Facial piercings require precise earring fitting. Too short will press in, too long will snag and look unsightly.
- Nostril: 2–4 months
- Septum: 6–8 weeks (fastest healing piercing!)
- Eyebrow: 6–8 weeks
- Bridge: 8–12 weeks
Material: For the nose, implant-grade titanium or 14k/18k gold is recommended, especially for those with sensitive skin. Avoid surgical steel if allergic to nickel.
| Piercing type | Bar thickness | Recommended length | Earring type |
|---|---|---|---|
| Nostril | 0.8 mm20g | 6–8 mm / Ø 8–10 mm | Labret, L-shape, ring |
| Septum | 1.2 mm16g | Ø 8–10 mm | Ring, clicker, retainer |
| Bridge / Earl / Third Eye | 1.2 mm16g | 10–12 mm | Barbell (straight) |
| Bindi | 1.2 mm16g | 8–10 mm | Labret |
| Eyebrow | 1.2 mm16g | 8–10 mm | Curved barbell |
| Anti-eyebrow | 1.2 mm16g | 8–10 mm | Banana or barbell |
Lip and mouth piercing sizes
Piercings around the mouth and lips require particular attention to size selection to avoid interference with eating, speaking, and oral hygiene.
The tongue swells significantly after piercing. The initial earring length is 16–18 mm, but after 2–3 weeks, you MUST shorten the earring to 14 mm to avoid damage to teeth and gums. This is a mandatory downsizing – it cannot be skipped.
| Piercing type | Bar thickness | Recommended length | Earring type |
|---|---|---|---|
| Labret (lower lip) | 1.2 mm16g | 8–10 mm | Labret (flat back) |
| Vertical labret | 1.2 mm16g | 10–12 mm | Banana |
| Horizontal labret | 1.2 mm16g | 12–16 mm | Barbell (long) |
| Madonna / Monroe | 1.2 mm16g | 8–10 mm | Labret |
| Medusa (Philtrum) | 1.2 mm16g | 8–10 mm | Labret |
| Angelbite (2 piercings) | 1.2 mm16g | 8–10 mm (each) | Labret |
| Spiderbite (2 piercings) | 1.2 mm16g | 8–10 mm (each) | Labret or small rings |
| Snakebite (2 piercings) | 1.2 mm16g | 8–10 mm (each) | Labret or rings |
| Tongue | 1.6 mm14g | 14–16 mm (after downsizing) | Barbell |
| Smiley (Upper frenulum) | 1.2 mm16g | Ø 8–10 mm | Small ring |
Torso piercing sizes
Torso piercings require thicker earrings (1.6 mm / 14g) for stability, safety, and proper healing.
- Healing time: 6–12 months (one of the longest healing piercings!)
- Initially use a banana of 10–12 mm length
- Avoid changing the earring for a minimum of 6 months
- Do not wear tight clothing that compresses the piercing during healing
| Piercing type | Bar thickness | Recommended length | Earring type |
|---|---|---|---|
| Navel | 1.6 mm14g | 10–12 mm | Banana |
| Nipple | 1.6 mm14g | 12–16 mm | Barbell or ring |
| Butterfly (Cleavage) | 1.6 mm14g | 12–16 mm | Surface barbell |
| Sternum | 1.6 mm14g | 12–16 mm | Surface barbell |
| Décolletage | 1.6 mm14g | 12–16 mm | Surface barbell |
| Hips (Hip / Hipbone) | 1.6 mm14g | 12–16 mm | Surface barbell |
Intimate piercing sizes
Intimate piercings require the highest quality materials and precise size matching. Anatomy is very individual – always consult with an experienced piercer regarding size.
Absolutely: use only implant-grade titanium ASTM F-136 or 14k gold minimum. Healing time is 4–8 weeks for most intimate piercings – they usually heal faster than external piercings.
| Piercing type | Bar thickness | Recommended length | Earring type |
|---|---|---|---|
| Christina | 1.6 mm14g | 12–16 mm | Banana or surface barbell |
| Isabella | 1.6 mm14g | 16–20 mm | Barbell |

Frequently asked questions about piercing sizes
Answers to the most important questions about size selection, earring changes, and safety.
When can I change my earring after piercing?
- Earlobe: 6–8 weeks
- Ear cartilage: minimum 3 months, preferably 6–12 months
- Lips/Nose: 2–4 months
- Tongue: 4–6 weeks (but downsizing after 2–3 weeks!)
- Navel: minimum 6 months, preferably a year
Golden rule: The first earring change should be performed by a professional piercer who will assess the healing status.
What is downsizing and when should it be done?
- Snag on clothes and hair
- Cause irritation and prolong healing
- Increase the risk of infection
Example: Fresh tragus piercing – 8 mm earring. After 6 weeks, once swelling has subsided, shorten to 6 mm for a better fit.
How to tell if an earring is too short or too long?
Earring too long: sticks out significantly from the ear/body, snags on clothes and hair, moves too freely, looks unsightly.
Ideal size: The earring should protrude slightly (approx. 1 mm on each side), not press into the skin, but also not stick out too much.
Can I stretch my piercing myself?
- Increase size by a maximum of 0.5–1 mm at a time
- Wait at least 4–6 weeks between subsequent stretches
- Use only titanium or implant-grade steel
- Never force it – if it hurts, the earring is too big
- Moisturize skin with oil (jojoba, vitamin E)
Note: Stretching above 10 mm may be irreversible – the hole will not shrink on its own.
What earring material to choose for a fresh piercing?
- Implant-grade titanium ASTM F-136 – best choice, hypoallergenic, lightweight
- 14k or 18k gold – safe, but more expensive
- Implant-grade steel ASTM F-138 – good quality, contains trace amounts of nickel
Avoid: 316L surgical steel (may contain nickel), silver (oxidizes), acrylic and plastic, plated earrings (flake off).
Internal or external thread – what's the difference?
Earrings with external thread have the thread on the surface of the bar, which can injure tissues. Not recommended for fresh piercings.
Tips for choosing the right size
8 rules to help you avoid common mistakes when choosing an earring.
Use longer earrings (+2–4 mm) due to swelling that appears within the first few days after piercing.
After full healing, switch to shorter earrings for a better fit, comfort, and aesthetics.
Diameter is measured from the inner edge. The smaller it is, the tighter the ring.
Length is measured between the ornaments, excluding the balls themselves. This is the most common mistake when ordering!
For fresh piercings, always choose earrings with internal thread – they do not irritate the channel.
Every person has different anatomy. Sizes in the tables are approximate – if in doubt, consult a piercer.
A cheap earring can cause allergies, prolong healing, or lead to infection. Do not skimp on material.
If the piercing hurts, is swollen for more than a week, pus appears, or the earring sinks in – immediately see a piercer or doctor.
How to choose earring size – step by step
Follow these 5 steps to choose the right size for any piercing.
Determine piercing type
Earlobe, helix, nose, navel, lip – each location has different thickness and length requirements.
Check standard size
Refer to the tables above – gauge and recommended length for each piercing.
Consider healing stage
- Fresh → longer (+2–4 mm)
- After 4–8 weeks → downsizing
- Healed → experiment
Choose earring type
- Labret – ear and face
- Ring – septum, daith (after healing)
- Banana – navel, eyebrow, rook
Choose safe material
Implant-grade titanium ASTM F-136 or 14k gold minimum. Do not skimp on material.
Sizes in the tables are approximate – every person has different anatomy. Correct size selection is key to quick healing and comfortable wear.
