Ring Size Chart

💍 Find Your Perfect Ring Size
A beautiful handmade ring deserves a comfortable, secure fit! Whether you're shopping for yourself or choosing a thoughtful gift, this guide will help you find your US ring size.
You don't need to own a ring to measure your finger. Choose whichever method works best for you!
💕 Method 1: Measure Your Finger With a Paper Strip
No ring or special measuring tools required!
-
✂️ Cut a narrow strip of paper, approximately ¼ inch (6 mm) wide.
-
💍 Wrap it around the base of the finger where you plan to wear your ring.
-
✏️ Mark where the paper overlaps.
-
📏 Lay the strip flat and measure from the end to your mark in millimeters (mm).
-
❤️ Compare that measurement with the Finger Circumference column in the chart below.
Important: The paper should fit snugly without squeezing. Make sure it can also slide over your knuckle.
🌸 Method 2: Use a Flexible Measuring Tape
-
📏 Wrap a flexible measuring tape around the base of your finger.
-
💕 Keep it comfortably snug, not tight.
-
✨ Read the measurement in millimeters.
-
💍 Match your measurement to the Finger Circumference column below.
For greater accuracy, repeat the measurement two or three times.
💎 Method 3: Measure a Ring You Already Own
-
💍 Choose a ring that fits the intended finger comfortably.
-
📏 Place it on a flat surface beside a millimeter ruler.
-
✨ Measure straight across the inside diameter, from one inner edge to the other.
-
❤️ Match your measurement to the Inside Diameter column below.
Do not include the thickness of the metal band in your measurement.

❤️ Helpful Tips for the Best Fit
-
🌷 Measure later in the day. Fingers may be slightly larger in the evening.
-
🌡️ Avoid extreme temperatures. Cold fingers shrink, while heat can cause swelling.
-
💍 Consider your knuckles. Your ring should slide over the knuckle without excessive force.
-
✨ Consider wider bands. Wide and multi-wire rings may fit more snugly than narrow bands and sometimes require a slightly larger size.
-
💕 Between sizes? Consider the larger size, but take the band style and knuckle fit into account.
-
📏 For maximum accuracy: Have your finger measured with a professional ring sizer, ideally in a band width similar to the ring you're purchasing.

Every ring I create is individually handcrafted with attention to detail. Some of my designs feature delicate wirework, sculpted metal, or multiple bands, which can influence how a ring feels on your finger.
