But once you know a few basics, it's actually super simple. And since you’re about to invest in something as timeless and elegant as a lab grown tennis bracelet, let’s make sure it fits just right.

In this guide, we will walk you through exactly how to find your perfect size, whether you’re going for a perfectly fit kada-style bracelet or a looser, fluid design. By the end, you’ll know exactly what to look for and feel confident clicking “Buy now” on the bracelet of your dreams from Aurelia Diamonds.

Why the Right Size Matters More Than You Think

We all know that tennis bracelets are meant to be sleek and minimal. But when the fit is off, even slightly-they either keep falling off, feel restricting, or don’t sit comfortably on your wrist. A perfectly sized lab grown tennis bracelet should feel like it belongs on your wrist.

Two Main Styles, Two Different Size Guides

Before we talk numbers, you should know this: there are two main types of bracelets you'll see at Aurelia Diamonds

1. Kada Bracelets

These are more structured and rigid, with a bangle-like fit. They don’t offer as much flexibility, so accurate sizing is essential.

2. Loose Tennis Bracelets

These are classic, fluid bracelets with a soft drape. They offer more flexibility in sizing and are ideal if you love a relaxed, comfortable fit.

Let’s look at the sizing details for each.

Sizing Guide for Kada-Style Lab Grown Tennis Bracelets

If you’re eyeing something like the Elegant Lab Grown Diamond Kada Bracelet (honestly, one of our favorites), you'll want to go by inner diameter in millimeters.

Here’s a quick size chart to help:

How to measure

• Take a measuring tape or strip of paper and wrap it around the widest part of your hand (usually where your thumb and fingers meet when you make a fist). 

• This will help determine what diameter will slide on comfortably.

Pro tip: If you’re between sizes, go

 for the slightly larger one for ease.

Sizing Guide for Loose Lab Grown Tennis Bracelets

If you’re looking at something like the Classic Lab Grown Tennis Bracelet or the Minimalist Sparkle Tennis Bracelet, these are designed to drape softly on your wrist and follow your natural movements.

Here’s the size breakdown

How to measure

Wrap a measuring tape around your wrist (just above the wrist bone). For a snug fit, add 0.5 cm. For a more loose fit and a traditional tennis bracelet look, add 1 to 1.5 cm.

Want a visual trick?
Use a ribbon or thread and wrap it around your wrist, then lay it flat against a ruler. Works like a charm when you don’t have a measuring tape handy.

Still Not Sure? Here's What We Recommend

• If you love a tailored, elegant look, go for a snug fit, just 0.5 to 1 cm above your wrist measurement.

• If you're more into comfort and movement, size up for a relaxed drape, especially for daily wear.

• Shopping for someone else? When in doubt, a 6.5 or 7-inch bracelet is usually the most common size for women.

And of course, if you’re ever unsure, Aurelia Diamonds’ support team is super helpful and can guide you through finding the right fit for the specific piece you’re eyeing.
