2mm–3mm: Tiny and subtle, ideal for second piercings or a delicate everyday look.

4mm: Small but noticeable, a balanced choice for minimal style.

5mm: A classic medium size that works well for everyday wear.

6mm: Slightly larger, offering more presence without being too bold.

Stud Earring Sizing FAQs

What is the most popular stud earring size?

The most common stud earring size is around 4mm–5mm. This size is noticeable without being too bold, making it a classic everyday choice that flatters most ears.

Are smaller studs better for multiple piercings?

Yes. Tiny studs (2mm–3mm) are often chosen for second or third piercings because they don’t overcrowd the ear. You can then pair them with slightly larger studs or hoops in your main piercing for a balanced, layered look.

How do I know what stud size suits me?

Think about the look you want. Smaller studs (2mm–3mm) are subtle and perfect for second piercings or a minimal style. Medium studs (4mm–5mm) balance comfort and presence. Larger studs (6mm–7mm) make more of a statement and are ideal if you prefer a bolder look.

What stud earrings are best if I have sensitive ears or metal allergies?

If you have sensitive ears, choose stud earrings made from hypoallergenic materials like sterling silver, solid gold, or surgical steel. Avoid cheap plated metals, as these often contain nickel, the most common cause of irritation. Our recycled sterling silver studs are naturally nickel-free and safe for everyday wear.

How do you clean stud earrings at home?

Soak your stud earrings in a bowl of warm water with mild washing-up liquid for 15–20 minutes. Gently scrub around the setting and posts with a soft toothbrush, then rinse and dry with a clean cloth. Avoid harsh chemicals or abrasives, as they can damage the silver and stones. For more tips, see our full Jewellery Care & Cleaning Guide.

Can I return stud earrings if they don’t fit?

For hygiene reasons, stud earrings cannot be returned once worn or tried on. We recommend using our Stud Earring Size Guide before purchasing to make sure you choose the right size with confidence.
