Tennis Bracelet Size Guide

How to Find Your Perfect Tennis Bracelet Size

A tennis bracelet should feel comfortable, secure and natural on the wrist. This guide will help you measure your wrist, choose your preferred fit and understand how much allowance to add before ordering.

At Carmen & Lucy Fine Jewellery, we create custom diamond tennis bracelets in solid gold, crafted to your wrist size and personal style.

01 / Bracelet Fit

Why bracelet fit matters

A well-fitted tennis bracelet should lightly drape across the wrist, offering gentle movement without excessive sliding or spinning.

If the bracelet is too tight, it may feel restrictive during daily wear. If it is too loose, it may catch on clothing, move uncomfortably or place extra strain on the clasp and diamond settings.

The right fit helps your bracelet feel effortless while also supporting its long-term wear.

How to measure your wrist correctly

You can measure your wrist using a flexible measuring tape, a strip of paper or a piece of string and a standard ruler. For the most accurate result, take your measurement in centimetres.

  • Wrap the measuring tape or string around the wrist where you would normally wear your bracelet.
  • Keep it snug against your skin without pinching or leaving large gaps.
  • Mark where the tape, paper or string overlaps, then measure that length against a ruler.

Even a few millimetres can change how a tennis bracelet feels, so it is worth measuring carefully.

03 / Comfort Allowance

Add a little extra for comfort

Once you have your wrist measurement, add a small allowance so the bracelet can move comfortably.

Snug fit Add approximately 1.5cm for a closer fit with minimal movement.
Standard fit Add approximately 2cm for a comfortable everyday fit.
Loose fit Add approximately 2.5cm or more for a softer, more draped look.


For example, if your wrist measures 16cm and you add 2cm for comfort, your bracelet size would be approximately 18cm.

04 / Fit Style

Choosing your preferred fit

Your final bracelet size should reflect the way you like to wear jewellery. Some clients prefer a close, secure fit, while others like a more relaxed drape.

The bracelet design also matters. A fine tennis bracelet may feel different from a piece with larger stones or a heavier setting, even when the length is the same.

If you plan to stack your tennis bracelet with other pieces, a slightly looser fit can allow the bracelet to move more naturally beside your other jewellery.

05 / Sizing Tips

Additional tips before ordering

  • Always measure the wrist you plan to wear the bracelet on, as wrist sizes can vary slightly.
  • Measure a favourite bracelet you already own if you want to compare your preferred fit.
  • Allow a little extra room if you plan to layer your bracelet with other pieces.
  • Try to get as close to the correct size as possible, as tennis bracelets can be difficult and costly to resize later.
