A hoop that fits sits neatly against your ear without pinching. Too small and it presses into the tissue; too big and it is more likely to catch. Here is how hoop sizes work, how to measure your ear at home, and which sizes suit each piercing, from first lobe to conch.

• 7 to 17mmInner diameters across our lobe hoops, from close huggie to statement hoop.
• 6 to 12mmInner diameters of our Classic Piercing Hoop, 1.2mm (16g) thick, for cartilage.
• 4.7gThe weight of one Large Bold Hoop, against 1.02g for a Small Bold Huggie.

Are hoop sizes inner or outer diameter?

Inner diameter is the distance across the inside of the hoop: the space your ear sits in, so it decides fit. Outer diameter runs across the outside edges, adding the hoop's thickness on both sides, so it decides how big the hoop looks.

The gap grows as hoops get chunkier: our Small Huggie is 7mm inside and 10.6mm outside, our Bold Hoop 12mm and 18.5mm. So when a size guide gives one number, check which it means.

Getting it right matters. For new piercings, the Association of Professional Piercers warns that jewellery that is too small raises the risk of swelling and embedding, and jewellery that is too large is more likely to catch.¹

How do you measure what size hoop you need?

You need a mirror and a ruler with millimetre markings.

1. Find the centre of the holeLook at the front of your ear and find the middle of the piercing.
2. Measure to the edgeHold the ruler flat against your ear and measure straight from the centre of the hole to the edge the hoop will wrap around: the bottom of your lobe, or the rim of your ear for cartilage.
3. Match it to an inner diameterChoose an inner diameter of at least that measurement. The closest size at or above it will hug your ear. Go a size up for more room, and bigger again for a hoop that hangs below the edge.
4. Check the thicknessMatch the gauge of the jewellery you wear now: our lobe hoops have 0.8mm or 1.0mm posts, and our Classic Piercing Hoop is 1.2mm (16g). Our earring gauge guide explains the numbers.

Already own a hoop that fits well? Measure across the inside: that is its inner diameter. A professional piercer can also help you choose the right size for your anatomy.²

Hoop earring size chart

Here is how our hoops compare. Width tells you how chunky the band looks.

A 7mm huggie only fits if your piercing sits about 7mm or less from the edge of your lobe. Any further and it will pinch, so size up.

What size hoops for a first, second or third hole?

Each hole sits a different distance from the edge of your lobe, so measure each one.

• First hole: anything from a huggie to a statement hoop, as long as the inner diameter is at least your measurement.
• Second hole: a huggie of 7 to 8mm keeps it neat and leaves space for the hoop below, if your measurement allows.
• Third hole: a small huggie or a stud, so the pieces step down in size as they go up your ear.

Only swap a stud for a hoop once the piercing has fully healed. The Association of Professional Piercers says it should be safe to change jewellery once a piercing is no longer tender or crusting, and the minimum initial healing time has passed.² Our guide to changing a lobe stud to a hoop covers the timing.

What size hoop for a helix, tragus, daith or conch?

Our Classic Piercing Hoop is a 1.2mm (16g) segment-style hoop in inner diameters from 6 to 12mm. For healed piercings, these are rough starting points. Your own measurement comes first:

• Helix: 6 to 8mm
• Tragus or rook: 6 to 8mm
• Daith: 8 to 10mm
• Conch: 10 to 12mm, because the hoop has to reach round the outer rim of your ear

The smaller size in each range sits snugly; the larger gives more room. Ear shape and placement vary, so ask a professional piercer to measure before you buy. Our conch jewellery guide and tragus jewellery guide go further, or browse our cartilage hoops.

Does the weight of a hoop matter?

Bigger, chunkier hoops weigh more. One Large Bold Hoop weighs 4.7g, against 1.02g for a Small Bold Huggie.

Over years of wear, that weight adds up. In a 2004 study comparing split and stretched earlobes, the authors attributed stretched lobes to the constant pull of heavy earrings.³ A 2025 review notes that as earlobes age they often sag and lengthen, particularly in people who have worn heavy earrings.⁴ The Association of Professional Piercers advises that extremely heavy pieces will seldom suit everyday wear.²

Material matters too. Titanium is less than half as dense as silver and under a quarter as dense as pure gold,⁵ so a titanium hoop weighs much less than the same shape in solid silver or gold.
