How to Get Your Ring Size: A Complete Guide

A well-fitting ring should slide on easily and come off with a slight tug over the knuckle. If it’s too tight, it can cut off circulation. If it’s too loose, you risk losing it.

Knowing your accurate size avoids the hassle of resizing and ensures comfort and security; especially for engagement rings, wedding bands, or custom-made pieces.

In this guide, you’ll learn how to get ring size, understand ring size charts, and get expert tips to ensure a perfect fit every time.

1. Use a Ring Sizer Printable

Best for: If you already have a ring that fits the intended finger.

Steps:

1. Download and print a ring size chart from our website. Ensure the printer settings are at 100% scale (no resizing or “fit to page”).
2. Once printed, verify the scale by measuring a reference line on the printout (usually included) to confirm accuracy.
3. Take the ring that fits well and place it on the printed sizing circles.
4. The correct size is the one where:
   • The inner edge of your ring matches the outer edge of the printed circle.
   • The circle should be just visible inside the ring, not hidden or too small.

Pro Tip: If the ring falls between two sizes, go with the larger one for comfort.

2. Measure Your Ring Size Using an Online Ring Sizer Tool

Best for: Users who want to use digital methods (with an existing ring).

Steps:

1. Visit ring sizer tool online.
2. Place your ring on your computer or smartphone screen.
3. Drag and resize the on-screen circle until it matches the inner edge of your ring.
4. The website will display your ring size in US, UK, or EU measurements.

3. Measure Your Finger with String or Paper

Best for: When you don’t have a ring and want to size your finger directly.

What you’ll need: A strip of paper or string, a pen, and a ruler (millimeters).

Steps:

1. Cut a narrow strip of paper (about 5 mm wide) or use a non-stretchy string.
2. Wrap it around the base of your finger—where the ring will sit. Don’t make it too tight; it should slide over the knuckle without resistance.
3. Mark the spot where the ends meet.
4. Flatten the paper or string and measure the length in millimeters (mm) using a ruler.
5. Use this measurement to find your size from the chart below:

Circumference (mm)	US Ring Size
44.2 mm	3
46.8 mm	4
49.3 mm	5
51.9 mm	6
54.4 mm	7
57.0 mm	8
59.5 mm	9
62.1 mm	10

Tips:

• Repeat 2–3 times for accuracy.
• Measure at the end of the day for best results (fingers swell slightly).

4. Use a Ring Sizer Tool (Plastic or Adjustable Ring Gauge)

Best for: Home users who want consistent and accurate sizing.

What it is: A plastic tool or a set of ring gauges (like a mini belt or keyring of ring samples) that you can buy online or from jewelry stores.

Steps:

1. Slip the ring sizer onto your finger and adjust it until it fits snugly.
2. It should feel secure but slide comfortably over your knuckle.
3. Read the size number printed on the tool.

Benefits:

• Reusable and great for measuring friends or family too.
• Usually shows US ring sizes, but some come with conversion charts for UK/EU/Asia.

5. Measure with Measuring Tape

Best for: A slightly more precise version of the paper/string method.

Steps:

1. Use a soft, flexible tape measure (like those used for sewing).
2. Wrap it around the base of your finger.
3. Read the measurement in millimeters (mm).
4. Convert that number to a ring size using the same chart as in Method 3.

Tips:

• Ensure the tape lies flat and tight without digging into the skin.
• If you’re in between sizes, choose the next size up.

6. Visit a Jeweler

Best for: The most accurate, stress-free option.

What happens:

• The jeweler will use a metal ring sizing set (a series of metal rings in half sizes) or a mandrel (a tapered sizing rod).
• You try on different rings until you find the perfect fit.
• The jeweler will tell you your size—often in multiple sizing systems.

Advantages:

• 100% accurate.
• Free at most jewelry stores.
• Ideal before buying expensive rings like engagement or wedding bands.

Tips for Measuring Ring Size

• Measure when your hands are warm (cold fingers are smaller).
• Measure the dominant hand—fingers on the dominant hand are usually slightly larger.
• Rings for wider bands often need to be half a size larger.
• If unsure, go up half a size for comfort.
