Size Guide
How to Find Your Perfect Bracelet Fit
Choosing the right size ensures your jewelry feels as good as it looks. A well-fitted bracelet should be secure enough not to slip off, but loose enough to drape elegantly.
Step 1: Measure Your Wrist
Choose one of these two easy methods to find your base wrist measurement:
-
Method A: Flexible Measuring Tape
Wrap a measuring tape around your wrist just above the wrist bone. Ensure it's snug against your skin but not pulling. -
Method B: String & Ruler
Wrap a string or a strip of paper around your wrist and mark where it overlaps. Lay the string flat against a ruler to measure the length.

Step 2: Choose Your Style of Fit
To calculate your final bracelet size, add the following allowance to your wrist measurement:
- Snug Fit: Add 0.5" (1.2cm) — Best if you want the bracelet to stay in place with minimal movement.
- Comfort Fit (Highly Recommended): Add 0.75"–1" (2cm–2.5cm) — Our most popular choice. Perfect for effortless movement and everyday comfort.
- Loose Fit: Add 1.25" (3cm) — Best for a draped, "bangle-like" look over the back of the hand.
Step 3: Refer to Our Size Chart
Compare your wrist measurement to our suggested bracelet sizes below.
| Wrist Measurement | Suggested Bracelet Size | Adjustable Bracelet Fit |
| 5.5"–5.9" / 14–15cm | 6.1" / 15.5cm | 6.3"–8.3" adjustable bracelets will fit with a relaxed drape |
| 6.0"–6.3" / 15–16cm | 6.7" / 17cm | Best fit for most adjustable Luvia bracelets |
| 6.4"–6.7" / 16–17cm | 7.1" / 18cm | Adjustable bracelets fit comfortably using the extender |
| 6.8"–7.1" / 17–18cm | 7.5" / 19cm | Choose full extender length or size up when available |
For Adjustable Bracelets
Many Luvia bracelets include an extender chain, such as 6.3 in + 2 in extender or 6.7 in + 1.57 in extender. This means the bracelet can be worn closer to the wrist or adjusted for a more relaxed fit.
If you are between sizes, we recommend using the extender for comfort rather than choosing a bracelet that feels too tight.

✨ Luvia Pro Tip for Tennis Bracelets
For our Moissanite Tennis Bracelets, a Comfort Fit is essential. This allows the bracelet to move slightly, catching light from every angle while helping the stones stay facing outward on your wrist.
In-between sizes? For tennis bracelets, we recommend sizing up for comfort and a more elegant drape.
How to Find Your Ring Size
Getting your ring size right makes all the difference. Use one of the methods below to find your measurement before ordering.
Method A: Measure an Existing Ring
If you already have a ring that fits well, place it on a ruler and measure the inner diameter (the distance across the inside of the ring). Use the chart below to find your size.
Method B: Measure Your Finger
- Wrap a thin strip of paper or a piece of string around the base of your finger.
- Mark where the paper overlaps.
- Lay it flat against a ruler and measure the length in millimeters.
- Divide by 3.14 to get the diameter, then use the chart below.
Ring Size Chart
| US Size | Inner Diameter (mm) | Inner Circumference (mm) |
| 4.5 | 15.3mm | 48.0mm |
| 5 | 15.7mm | 49.3mm |
| 5.5 | 16.1mm | 50.6mm |
| 6 | 16.5mm | 51.8mm |
| 6.5 | 16.9mm | 53.1mm |
| 7 | 17.3mm | 54.4mm |
| 7.5 | 17.7mm | 55.7mm |
| 8 | 18.2mm | 57.2mm |
| 8.5 | 18.6mm | 58.4mm |
| 9 | 19.0mm | 59.7mm |
| 9.5 | 19.4mm | 61.0mm |
Ring Sizing Tips
- Fingers are slightly larger in the evening and in warm weather. Measure at the end of the day for the most accurate fit.
- If you are between sizes, we recommend choosing the larger size for a more comfortable fit.
- For rings with wider bands (such as eternity or pavé bands), consider sizing up by half a size for comfort.
- Adjustable open-band rings do not require an exact size — they flex to fit most fingers.
Earring Size Reference
Earring sizing at Luvia refers to the stone carat weight or total carat weight (TCW) per pair, not a physical body measurement. Use the guide below to understand what each size looks like and how to choose.
Stud Earring Size Guide
| Stone Size | Approx. Diameter | Look & Feel |
| 0.3 ct per ear | ~4.0mm | Subtle, delicate — ideal for everyday minimal wear |
| 0.5 ct per ear | ~5.0mm | Classic everyday stud — the most popular size |
| 1.0 ct per ear | ~6.5mm | More visible presence — great for special occasions or statement styling |
| 1.5 ct per ear | ~7.5mm | Bold and luminous — a strong everyday or evening statement |
Earring Sizing Tips
- Stud sizes are measured per ear. A pair listed as 1.0 CTW means 0.5 ct per ear.
- If you prefer a subtle everyday look, choose 0.3–0.5 ct per ear.
- If you want more visible sparkle or a statement look, choose 1.0 ct per ear or above.
- Fancy-cut studs (pear, trillion, heart, Asscher) may appear slightly larger or smaller than round studs of the same carat weight due to their shape.
Note on Returns: For hygiene reasons, all earrings are final sale and cannot be returned or exchanged unless defective or incorrect. Please review your size selection carefully before ordering.
Necklace Length Guide
Necklace length determines where a pendant sits on your neckline. Use the guide below to choose the right length for your style and neckline.
Necklace Length Chart
| Length | Where It Sits | Best For |
| 14" / 35cm | Choker — sits at the base of the neck | Crew necks, off-shoulder tops, layering as the shortest piece |
| 16" / 40cm | Collarbone — sits just at or above the collarbone | Most necklines; the most popular everyday length |
| 18" / 45cm | Below collarbone — sits 1"–2" below the collarbone | V-necks, scoop necks, layering as a mid-length piece |
| 20" / 50cm | Upper chest — sits at the top of the chest | Deeper necklines, relaxed layering |
| 22"–24" / 55–60cm | Mid-chest — sits at the center of the chest | Statement pendants, longer layering looks |
Luvia Necklace Lengths
Most Luvia necklaces come with a 16" chain + 2" adjustable extender, allowing you to wear them at 16" or extend to 18". This covers the two most popular everyday lengths and works with most necklines.
Necklace Sizing Tips
- If you prefer the pendant to sit lower, use the extender to adjust to 18".
- For layering, pair a 16" necklace with an 18" or 20" piece for a clean, staggered look.
- Pendant size also affects perceived length — a larger pendant will draw the eye downward and appear to sit lower than a delicate solitaire at the same chain length.
- Not sure which length to choose? The 16" + extender option works for most body types and necklines.
