How to Measure Your Ring Size – The Complete Guide

Rings aren’t just accessories—they’re personal statements. Whether you’re gearing up for a proposal, celebrating a milestone, or treating yourself to a handcrafted masterpiece, one thing is essential: the perfect fit. Learning how to measure your ring size is your first step toward finding a ring that feels as good as it looks.

Imagine slipping a ring onto your finger and feeling it settle perfectly—neither too snug nor at risk of falling off. That feeling of harmony is exactly what you want, especially when you’re choosing something as meaningful as a custom wedding band or a one-of-a-kind engagement ring.

In this guide, we’ll walk you through the best ways to measure your ring size at home and when it makes sense to see a professional. You’ll get familiar with tools like ring size charts and printable sizers, plus tips to help you get it right the first time. We’ll also share some stories and insights from Vidar Jewelry’s customers who found their perfect fit, both in style and in size.

Why Ring Size Matters

A ring that fits just right should feel like a natural extension of you. Too tight, and it’s uncomfortable. Too loose, and you risk losing something precious. When it comes to significant rings—engagement rings, wedding bands, or heirloom pieces—precision matters more than ever.

Here’s what could happen with the wrong size:

• A ring that slips off during everyday activities (yes, even while washing dishes)
• Circulation issues or discomfort from a tight fit
• Constant spinning or movement of the ring
• Difficulty resizing, especially for intricate or gemstone-set bands

At Vidar Jewelry, we know how much the right fit matters—especially when you’re customizing a piece designed to reflect your story. We often work with clients who want their ring to symbolize balance, commitment, or identity. And just like those themes, the fit has to be right.

Ring Sizing Methods You Can Try at Home

Now, here are two trusted at-home methods to try:

1. Measuring with String or Paper

Wrap a piece of string or a thin strip of paper around the base of your finger. Mark where the end overlaps. Lay it flat and measure it with a ruler (in millimeters). Then use a conversion chart to find your size.

Pro Tip: Measure a few times, especially at different times of day. Fingers swell!

One of our customers, Alex from Portland, told us he tried this method while proposing to his partner in secret. He sneakily borrowed one of their rings and measured it using this trick. Spoiler alert: it worked perfectly—and so did the proposal.

2. Using a Ruler or Tape Measure

If you have a flexible measuring tape, it can give you a quick and reasonably accurate size. Wrap it around your finger and note the circumference.

Now take that measurement and match it to a sizing chart. Make sure the tape lies flat and is snug but not tight.

Vidar Insight: Many of our customers start with this method before ordering one of our custom creations. Start simple, then fine-tune.

Tips for Getting the Most Accurate Results

To get the best results at home, follow these easy tips:

• Measure your finger at the end of the day when it’s at its largest—morning fingers can be misleading.
• Avoid measuring when your hands are cold or wet, as that can shrink your finger slightly.
• Measure multiple times for consistency. A one-time measurement might not be reliable.
• Consider your knuckle size—if you have larger knuckles, you may need to size up slightly to allow the ring to slide over comfortably.
• Test the fit by sliding the ring sizer or string on and off a few times. It should go on easily but come off with a bit of resistance.
• Consult with a jeweler like those at Vidar Jewelry if you’re unsure. We’re happy to help you double-check before crafting your dream ring.

Use a Printable Ring Sizer

You can usually download a printable ring sizer directly from trusted jewelry websites. Vidar Jewelry offers this tool along with personal guidance to walk you through the steps.

Want something a little more official without leaving the house? A printable ring sizer is the way to go. You can find one online, print it out at 100% scale, and either

• Cut out a measuring strip with size markings, or
• Place an existing ring over printed circles to find your size

Pros:

• Fast, easy, and free
• Useful for checking the sizes of existing rings

Cons:

• Slight printer misalignments can skew results
• Less accurate for wide bands or unusual finger shapes

Hot Tip: Many boutique jewelers, including Vidar Jewelry, offer downloadable sizing tools and personal assistance to help you get it right. Some clients even share their printable-size results during a virtual consultation with our team to confirm fit.

Refer to a Ring Size Chart

Once you have your measurement, it’s time to match it to a ring size chart. Ring sizes vary slightly by country, but here’s a quick example:

• U.S. Size 9 = 18.9mm diameter
• U.K. Size R = 18.8mm diameter
• European Size 59 = 18.8mm diameter

Most charts will show the diameter and circumference along with size labels. Just match your measured length to the chart and note your size in the appropriate system. If in doubt, choose a slightly larger size over a smaller one—tight rings are harder to adjust.

Many Vidar Jewelry rings, especially those crafted in two-tone metals or with intricate gemstones like sapphires or emeralds, require extra attention when sizing. A half size here or there can make a big difference.

International Ring Size Conversion Guide

Shopping globally? You’ll want to know how to convert your ring size. Here’s a quick reference:

• U.S. 7 = U.K. N = EU 54 = Japan 14
• U.S. 10 = U.K. T½ = EU 62 = Japan 20

If you’re buying from a boutique like Vidar Jewelry, our team will help make sure your size is converted accurately—no guesswork, just expert guidance. We’ve worked with clients from Tokyo to Berlin to Los Angeles, and we make sizing across continents seamless.

Quick Tip: Never assume the size will be the same across brands or regions. Always double-check!

When to Choose Professional Ring Sizing

While DIY sizing is great, some moments in life deserve the extra precision of a professional jeweler.

When should you go pro?

• You’re designing a custom engagement or wedding ring
• The ring features a wide or uniquely shaped band
• You’re unsure after using at-home methods

A professional uses specialized tools like mandrels and sizing rings that account for band width, knuckle fit, and more. At Vidar Jewelry, we offer free consultations with experienced designers who can guide you to the perfect fit. We often recommend this route for thicker bands or rings with stone-studded edges.

Pro Tips for Accurate Ring Measurement

• Time of Day Matters: Your fingers swell slightly in the evening and during warmer weather. Measure when your hands are at a normal temperature.
• Avoid After Exercise or Salt-Heavy Meals: Both can cause temporary swelling.
• Measure More Than Once: Try different times and days to find an average.
• Use a Ring That Fits: If you already have a ring that fits the correct finger, measure its inner diameter and compare it to a ring size chart.
• Consider Your Lifestyle: If you’re active or your job involves working with your hands, opt for a slightly snugger fit so your ring stays secure.

Our artisans at Vidar understand that a perfect fit isn’t just about numbers—it’s about how it feels, both physically and emotionally. A ring should be part of your rhythm, your expression, your everyday story.
