Body Jewelry Size Guide

Not sure what size you need? We've got you. Use this guide to find your fit — and when in doubt, always check with your piercer for your exact gauge and anatomy.


📏 How to Measure Your Jewelry

Different jewelry styles are measured differently. Here’s how to get it right:

Jewelry Type What to Measure How
Straight & Curved Barbells
(tongue, navel, eyebrow)
Wearable length Measure the straight-line distance between the balls or decorative ends — not the total bar length
Hoops & Captive Bead Rings
(septum, ear)
Internal diameter Measure across the inside of the ring at its widest point, from inner edge to inner edge
Labrets & Flat-Back Studs
(lip, tragus, cartilage)
Post length Measure from the back of the flat disc to the bottom of the ball or decorative top

Tip: Gauge (thickness) is always measured the same way regardless of style — it’s the diameter of the post or bar itself. The lower the gauge number, the thicker the jewelry (14G is thicker than 16G).


💍 Septum Rings

Measurement Standard Size Notes
Gauge 16G (1.2mm) Most common — used by most piercers
Gauge — thicker 14G (1.6mm) Less common, some piercers prefer this
Diameter — snug 5/16" (8mm) Close-to-nose, minimal drop
Diameter — standard 3/8" (10mm) Most common healed fit
Diameter — range 6mm–12mm Varies by anatomy and personal preference

Tip: 16G / 8–10mm fits most people. If you’re unsure, check with your piercer — they’ll know your exact gauge and anatomy.

How to Wear

  1. Pinch the hoop gently at the hinge point
  2. The segment clicks open — no tools needed
  3. Slide through your septum piercing and click closed until you feel/hear it snap

👃 Nose Rings & Studs (Nostril)

Measurement Standard Size Notes
Gauge — most common 20G (0.8mm) Standard for most nostril studs
Gauge — slightly thicker 18G (1.0mm) Common alternative, slightly more durable
Stud length (wearable) 1/4" (6mm) – 5/16" (8mm) Standard nostril depth range
Hoop diameter — snug 6mm Close-fitting, minimal drop
Hoop diameter — standard 8mm Most common hoop fit for nostrils

Nose jewelry comes in several styles: nose screws, L-shaped pins, seamless rings, and hinged hoops. All fit the same gauge piercing — it’s just a matter of preference. 20G is the most common for standard studs.

How to Wear (Nose Screw)

  1. Insert the straight post into your nostril piercing
  2. Gently twist clockwise until the curved screw end tucks inside the nostril
  3. It should sit flush against the skin with no gap

💋 Lip & Labret Piercings

Style Standard Gauge Standard Length Notes
Labret stud 16G (1.2mm) 5/16" (8mm) Most common healed labret size
Labret — initial 16G (1.2mm) 3/8" (10mm) Longer for swelling during healing
Monroe / Madonna 16G (1.2mm) 5/16"–3/8" Upper lip placement
Lip ring (hoop) 16G (1.2mm) 5/16"–3/8" diameter Seamless or hinged hoop styles

Tip: After healing, most people downsize their labret from 3/8" to 5/16" for a snugger, more comfortable fit.

How to Wear (Labret Stud)

  1. Unscrew the decorative top counterclockwise
  2. Insert the flat-back post through your lip piercing from the inside out
  3. Screw the top back on clockwise until snug
  4. The flat disc inside should sit flush against the inner lip — not pressing or loose

👅 Tongue Barbells

Measurement Standard Size Notes
Gauge 14G (1.6mm) Universal standard for tongue piercings
Initial length 3/4" – 7/8" (19–22mm) Longer to allow for significant swelling during healing
Healed length 5/8" (16mm) Most common size once swelling subsides (2–4 weeks)
Shorter healed 1/2" (12mm) For thinner tongues or snugger fit

Tip: Tongue piercings swell significantly — always start with a longer bar (19–22mm) and downsize to 16mm once fully healed. A bar that’s too short on a swollen tongue can embed into the tissue and cause serious damage. Bar length also varies depending on tongue thickness — your piercer will size you correctly at the initial appointment.

How to Wear

  1. Unscrew the top ball counterclockwise
  2. Insert the barbell vertically through your tongue piercing from bottom to top
  3. Screw the top ball back on clockwise until snug
  4. Check tightness daily — tongue barbells can loosen with eating and movement

🌙 Daith Rings

Measurement Standard Size Notes
Gauge 16G Standard daith gauge
Diameter 5/16"–3/8" (8–10mm) Depends on ear anatomy

How to Wear

  1. Open the hinged segment at the clasp point
  2. Guide the hoop through the daith fold of your inner ear
  3. Snap closed — it should sit snugly in the cartilage fold

💎 Belly Rings (Navel)

Measurement Standard Size Notes
Gauge 14G Universal standard for navel piercings
Shaft Length 3/8" (10mm) Most common — fits standard anatomy
Longer shaft 7/16" (11mm) For deeper navels or during pregnancy

How to Wear

  1. Unscrew the top ball or decorative end counterclockwise
  2. Insert the bar through your navel piercing from bottom to top
  3. Screw the top end back on clockwise until snug — do not overtighten

🔩 Nipple Barbells (Straight)

Measurement Standard Size Notes
Gauge 14G (1.6mm) Standard thickness for nipple piercings
Initial length 5/8" (16mm) Standard for fresh piercings — allows room for swelling
Healed — short 3/8" (10mm) Snug fit once fully healed
Healed — medium 1/2" (12mm) Most popular healed size
Healed — longer 9/16" (14mm) For more comfort or larger anatomy

Tip: Most people downsize from 5/8" to a shorter bar (1/2" or 9/16") after their piercing is fully healed for a more comfortable, flush fit.

How to Wear

  1. Unscrew one end ball counterclockwise
  2. Insert the straight barbell horizontally through your nipple piercing
  3. Screw the end ball back on clockwise until secure
  4. The barbell should sit flush — not too tight, not loose

💠 Cartilage Piercings

All cartilage placements typically use 16G (1.2mm) as the standard gauge unless noted. Here’s a full breakdown by placement:

Placement Standard Gauge Standard Size Jewelry Style Notes
Helix (Upper Rim) 16G 1/4" (6mm) – 5/16" (8mm) Barbell or hoop Most popular cartilage piercing
Tragus (Front Nook) 16G 1/4" (6mm) – 5/16" (8mm) Flat-back stud Small flap in front of ear canal
Conch (Inner Bowl) 16G or 14G Stud: 1/4" (6mm) – 3/8" (10mm)
Hoop: 3/8" (10mm) – 1/2" (12mm)
Stud or hoop Longer post for initial swelling; larger hoop diameter for inner conch anatomy
Rook 16G 5/16" (8mm) – 3/8" (10mm) Ring or curved barbell Inner ridge above daith
Industrial (Scaffold) 14G (1.6mm) standard; 16G sometimes used Length: 1-1/4" (32mm), 1-3/8" (35mm), or 1-1/2" (38mm)
Ball size: 5mm or 6mm
Straight barbell Exact length depends on ear anatomy. Longer bar used initially for swelling — a professional piercer can fit a shorter custom bar after healing

Tip: Cartilage piercings can be worn with hoops, flat-back studs, or curved barbells depending on placement. When in doubt, ask your piercer what style suits your anatomy best.


📏 General Sizing Tips

  • Gauge refers to the thickness of the jewelry post — the lower the number, the thicker the bar (e.g., 14G is thicker than 16G)
  • Diameter is the inner measurement of a hoop or ring
  • Shaft/bar length is the wearable length of a straight or curved barbell
  • All Pressha jewelry is labeled with gauge and size in the product variant selector
  • New styles may be added — check back or contact us if you need help sizing a specific piece
