Jewelry Size Guide
Quick Fit Overview
This page brings together the core size references for the main jewelry categories offered at Bijoux-NYC Direct. While individual product pages always control the exact specifications, these charts help you visualize what different measurements usually look and feel like in real use.
Earrings
Compare stud millimeter sizes, hoop diameters, and drop lengths to get the right scale for daily wear or statement styling.
Bracelets
Measure your wrist, then add a comfort allowance based on whether you want a close, classic, or relaxed fit.
Necklaces
Different chain lengths sit very differently on the neckline. Use the chart below to choose a more intentional look.
Rings
Inside diameter and finger circumference both matter. When in between sizes, the wider the band, the more fit becomes important.

How to Measure Before You Buy
Measurements are easiest when you use a soft tape measure, a strip of paper, or a string plus a ruler. Take measurements at normal room temperature and check more than once for consistency. Fingers, wrists, and even preferred necklace placement can change depending on season, time of day, and styling preference.
For Earrings
- Use a ruler to compare millimeters against an existing pair you already wear.
- Stud sizes are usually given in millimeters or approximate carat weight appearance.
- Hoops are usually measured by outer diameter.
- Drops and dangles are measured by total hanging length.
For Bracelets
- Wrap the tape around your wrist just above the wrist bone.
- Add about 1/4" to 1/2" for a close fit.
- Add about 3/4" for a classic fit.
- Add about 1" for a looser fit.
For Necklaces
- Measure a chain you already own from end to end.
- Stand in front of a mirror and hold a string at different lengths.
- Consider neckline, pendant size, and whether you plan to layer.
For Rings
- Measure the intended finger at the end of the day for the most realistic fit.
- Do not measure cold fingers only.
- If using a current ring, measure the inside diameter, not the outer edge.
- Wider bands may need a slightly roomier fit than thin bands.
Earring Size Chart
Earring size affects visibility, comfort, and how formal or subtle the final look feels. A millimeter difference can look much larger on the ear than it sounds on paper, especially with studs and hoops.
Stud Earring Guide
| Approx. Size | Millimeter Range | Look | Best For |
|---|---|---|---|
| Petite | 2 mm to 3 mm | Very subtle, delicate sparkle | Second piercings, minimal wear, understated daily styling |
| Small | 4 mm | Classic light presence | Everyday wear, professional settings, refined layering |
| Medium | 5 mm to 6 mm | Balanced and noticeable | Most versatile everyday stud size |
| Bold | 7 mm to 8 mm | More visible on the ear | Dress wear, larger visual impact, standout daily look |
| Statement | 9 mm+ | High presence and brighter face framing | Special occasions or stronger style preference |
Hoop Earring Guide
| Hoop Diameter | Style Impression | Typical Wear |
|---|---|---|
| 10 mm to 15 mm | Huggie or close-to-lobe look | Minimalist daily wear, layered piercings |
| 16 mm to 25 mm | Small to medium classic hoop | Everyday versatile sizing |
| 26 mm to 40 mm | Noticeable hoop presence | Fashion-forward daily or evening wear |
| 41 mm+ | Large statement hoop | High-visibility styling and stronger silhouette |
Drop and Dangle Earring Guide
| Length | Look | Best Use |
|---|---|---|
| Under 20 mm | Short drop | Light movement, polished daily wear |
| 20 mm to 40 mm | Medium drop | Balanced dress styling and day-to-night wear |
| 40 mm to 60 mm | Long drop | Elegant framing for special occasions |
| 60 mm+ | Statement dangle | Formal, event, or highly visible styling |
Bracelet Size Chart
Bracelets should feel secure without feeling restrictive. The right fit depends not only on wrist size, but also on bracelet style. A bangle, line bracelet, cuff, and chain bracelet can all wear differently even at the same stated length.
How to Measure Your Wrist
Wrap a soft tape measure around your wrist just above the wrist bone. Record that measurement, then use the chart below to choose your preferred fit.
| Wrist Measurement | Close Fit | Classic Fit | Relaxed Fit |
|---|---|---|---|
| 5.5" | 5.75" to 6.0" | 6.25" | 6.5" |
| 6.0" | 6.25" to 6.5" | 6.75" | 7.0" |
| 6.5" | 6.75" to 7.0" | 7.25" | 7.5" |
| 7.0" | 7.25" to 7.5" | 7.75" | 8.0" |
| 7.5" | 7.75" to 8.0" | 8.25" | 8.5" |
Bracelet Style Notes
- Line bracelets / tennis bracelets: Usually look best with a controlled but comfortable fit.
- Chain bracelets: Can wear slightly looser depending on design.
- Cuffs: Need enough opening room while still staying in place on the wrist.
- Bangles: Must pass over the hand, so hand size matters in addition to wrist size.
Necklace Size Chart
Necklace length changes the entire presentation of a chain or pendant. The same pendant can look much more delicate at one length and much more prominent at another. Layering, neckline, and chain thickness all influence the result.
| Length | Typical Placement | Style Use |
|---|---|---|
| 14" | Close to the neck | Choker fit, strongest neckline definition |
| 16" | Base of the neck | Classic short chain, ideal for smaller pendants |
| 18" | Just below the collarbone | Most versatile standard necklace length |
| 20" | Upper chest | Slightly longer drape, useful for larger pendants |
| 22" | Upper to mid chest | Layering length, more relaxed look |
| 24" | Mid chest | Longer pendant presentation and layered styling |
| 30"+ | Lower chest | Statement or fashion layering length |
Choosing Necklace Length More Accurately
- Use a string and mirror to test where you want the pendant to fall.
- Shorter chains usually frame the neckline more directly.
- Longer chains often work better for layering or larger focal pendants.
- Personal height, neck width, and pendant size can all shift how a stated length appears.
Ring Size Chart
Ring fit should feel secure while still sliding over the knuckle with light resistance. If you are between sizes, weather, hand temperature, and band width can make a measurable difference in comfort.
| US Ring Size | Inside Diameter (mm) | Finger Circumference (mm) |
|---|---|---|
| 4 | 14.9 | 46.8 |
| 4.5 | 15.3 | 48.0 |
| 5 | 15.7 | 49.3 |
| 5.5 | 16.1 | 50.6 |
| 6 | 16.5 | 51.9 |
| 6.5 | 16.9 | 53.1 |
| 7 | 17.3 | 54.4 |
| 7.5 | 17.7 | 55.7 |
| 8 | 18.1 | 57.0 |
| 8.5 | 18.5 | 58.3 |
| 9 | 18.9 | 59.5 |
| 9.5 | 19.4 | 60.8 |
| 10 | 19.8 | 62.1 |
| 10.5 | 20.2 | 63.4 |
| 11 | 20.6 | 64.6 |
| 11.5 | 21.0 | 65.9 |
| 12 | 21.4 | 67.2 |
Ring Fit Notes
- Measure the exact finger that will wear the ring.
- Dominant hands are often slightly larger.
- Wide bands can feel tighter than slim bands in the same size.
- If a ring is a gift and you are estimating, it is better to verify than assume.
General Fit Tips
When to Double-Check Size
- When ordering a gift
- When choosing a wider ring band
- When buying rigid bangles or cuffs
- When selecting statement earrings or long drops
- When layering multiple necklace lengths together
What Affects Fit
- Temperature and swelling
- Knuckle size
- Band width and design style
- Pendant weight and chain thickness
- Personal preference for close versus relaxed wear
Jewelry Size Guide FAQs
How do I know which necklace length is best for me?
The simplest method is to use a string in front of a mirror and test the drop visually. An 18-inch necklace is the most common starting point because it usually falls just below the collarbone, but pendant size, neck width, and layering goals all matter.
What bracelet size should I order if I want a comfortable everyday fit?
Measure your wrist and add roughly 3/4 inch for a classic everyday fit. If you prefer a close fit, add less. If you want more movement, add more. Chain bracelets and tennis bracelets may feel different even at the same length.
Are stud earring sizes easy to judge online?
Stud size can be deceptively small or large when only reading a measurement. A side-by-side millimeter comparison is the best way to judge scale. In most cases, 5 mm to 6 mm is a balanced everyday size, while 7 mm and up becomes more visually prominent.
What should I do if I am between ring sizes?
That depends on the design. Narrow bands often allow a bit more flexibility, while wider bands may require a slightly larger fit for comfort. If you are between sizes, it is best to check the specific style and sizing notes before ordering.
Can wrist size and hand size both matter for bracelets?
Yes. Wrist size is the main measurement for flexible bracelets, but rigid bangles must also pass over the hand. That is why bangles should be measured differently than chain bracelets or tennis bracelets.
Does Bijoux-NYC Direct list exact dimensions on product pages?
Product pages should be used as the final source for exact specifications whenever those measurements are available. This guide is designed to help with general comparison and fit planning across earrings, bracelets, necklaces, and rings.
