Hoop earrings are one of those jewelry pieces that never go out of style. They can be tiny and subtle or big and bold, and they always add a little something special to your look. But if you have ever shopped for hoops online, you know how confusing the sizes can be. A “30 mm hoop” might sound small until you see it in person, while a “70 mm hoop” can turn out much larger than you imagined.
That is why it helps to know exactly how to measure hoop earrings. In this guide, we will go step by step through the process so you can shop with confidence and pick the right size for your style.
Why It Helps to Measure Hoop Earrings
When you buy in a store, you can simply hold the earrings up to your ear. Online, though, you have to rely on numbers. Learning how to measure hoop earrings can:
-
Save you from buying hoops that are way too small or too big
-
Help you compare sizes between different stores and brands
-
Make it easier to find the perfect everyday size
-
Give you a better idea of how different hoops will look on your face
Diameter: The Main Measurement to Know
The first and most important measurement is the diameter. This is the distance from one side of the hoop straight across to the other side. Most jewelry shops list hoop earrings in millimeters (mm). Sometimes you will see inches instead.
Here is a quick guide to help you picture hoop sizes:
-
10–20 mm (0.4–0.8 inches): These are small hoops or huggies that sit close to the ear. Great for everyday wear.
-
25–35 mm (1–1.4 inches): These are medium hoops, which are versatile and easy to dress up or down.
-
40–50 mm (1.5–2 inches): Large hoops that make a noticeable statement.
-
55–70 mm (2.2–2.8 inches): Extra-large hoops that really stand out and are often worn for bold fashion looks.
When you measure your own hoops, always measure straight across from the inside edge. This gives you the inner diameter, which tells you how much space your ear has inside the hoop.
How to Measure Hoop Earrings at Home
Measuring hoop earrings is easier than you might think. All you need is a ruler or a caliper.
-
Lay the hoop flat on a table.
-
Place your ruler across the widest part of the circle.
-
Check the number in millimeters or inches.
-
Rotate the hoop and measure again just to make sure it is accurate.
Tip: Millimeters give you a more exact size. For example, saying “30 mm” is clearer than “about 1 inch.”
Thickness Also Matters
Besides diameter, hoop earrings also come in different thicknesses. Some are slim and delicate, while others are chunky and bold.
-
Thin hoops (1–2 mm) are light and elegant.
-
Medium hoops (2–4 mm) have more presence but are still easy to wear.
-
Chunky hoops (5 mm or more) are trendy and make a fashion statement.
To measure thickness, place your ruler at the side of the hoop and measure the width of the metal.
Measuring Drop Length
Some hoops are not perfectly round or may have extra details hanging down. In that case, you might also want to measure the drop length. This is the distance from the very top of the earring (where it meets your ear) to the bottom of the hoop or charm.
Knowing the drop length helps if you are worried about earrings touching your jawline, brushing your shoulders, or simply hanging lower than you want.
A Quick Size Conversion
Since many hoop earrings are listed in millimeters, it helps to know how that translates to inches. Here are some common sizes:
-
10 mm = 0.4 inches
-
20 mm = 0.8 inches
-
30 mm = 1.2 inches
-
40 mm = 1.6 inches
-
50 mm = 2 inches
-
70 mm = 2.75 inches
A quick rule to remember: 25 mm is about 1 inch.
Finding the Right Hoop Size for You
Everyone has their favorite hoop size, but here are a few tips to help you choose.
For Everyday Wear
Small hoops and huggies (10–20 mm) are perfect if you want something simple that does not get in the way. They are comfortable, professional, and match just about everything.
Example: Gold Double Diamond Hoop Earring.
For Versatility
Medium hoops (25–35 mm) are a go-to size for many people. They are not too flashy but big enough to stand out. You can wear them with jeans and a T-shirt or with a dress on a night out.
For Making a Statement
Large hoops (40 mm and above) are perfect when you want all eyes on you. They are bold and stylish, especially with sleek hairstyles or evening outfits.
Example: Gold Rope Hoop Earrings.
Matching Hoops to Your Face Shape
The size of hoops you wear can also highlight your features.
-
Round faces: Longer or larger hoops help create balance.
-
Oval faces: Lucky you, most hoop sizes work well.
-
Square faces: Rounded hoops can soften strong angles.
-
Heart-shaped faces: Medium hoops look flattering by balancing your features.
Tips for Shopping Online
When buying hoop earrings online, it can be tricky to know what size you are really getting. Here are some tips:
-
Always look at the size in millimeters. Words like “small” or “large” are not exact.
-
Compare the size to something familiar. For example, a quarter coin is about 24 mm wide.
-
Check photos of the earrings on a model, if available.
-
Read customer reviews for feedback on whether the earrings looked bigger or smaller in real life.
Caring for Your Hoop Earrings
Once you find your perfect size, you will want to keep your hoops looking good. Store them in a jewelry pouch, especially large ones that can scratch. Avoid wearing oversized hoops when you are active so they do not get caught on clothing or hair. And give them a gentle clean every so often to keep the shine.
Conclusion
Knowing how to measure hoop earrings makes shopping so much easier. By paying attention to the diameter, thickness, and drop length, you can choose the size that suits your face, your style, and your lifestyle.
The next time you see a pair listed as “30 mm” or “50 mm,” you will know exactly what that looks like and whether it is the right choice for you. Whether you love tiny huggies or oversized statement hoops, the right measurement ensures you always pick the perfect pair.
