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.
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.
-
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.
Can I wear large stud earrings every day?
You can, as long as they feel comfortable for you. Larger studs (6mm–7mm) are heavier and more noticeable, so some people reserve them for special occasions. For daily wear, many prefer 4mm–5mm as they’re practical, light, and versatile.

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.
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.
