Engraved Bond | Ring Size Guide

1. International Ring Size Conversion Chart

Use this table to find your perfect fit. We recommend measuring the inside diameter of a ring you already own for the highest accuracy.

US Size	Inside Diameter (mm)	Inside Diameter (inches)	Inside Circumference (mm)
Size 3	14.1 mm	0.55"	44.2 mm
Size 4	14.9 mm	0.58"	46.8 mm
Size 5	15.7 mm	0.62"	49.3 mm
Size 6	16.5 mm	0.65"	51.9 mm
Size 7	17.3 mm	0.68"	54.4 mm
Size 8	18.1 mm	0.71"	57.0 mm
Size 9	19.0 mm	0.75"	59.5 mm

2. How to Measure Your Size at Home

Method A: Measure an Existing Ring

Select a ring that fits the desired finger perfectly.
Use a ruler to measure the inside diameter (the space across the middle, excluding the metal).
Compare the measurement to the "Inside Diameter" column in the chart above.

Method B: The Paper Strip Method

Wrap a thin strip of paper or a piece of string around the base of your finger.
Mark the exact point where the ends meet.
Lay the paper flat and measure the distance with a ruler in millimeters. This is your circumference.
Match this number to the "Inside Circumference" column above.

3. Pro Tips for the Perfect Fit

The "In-Between" Rule: If you fall between two sizes, we always recommend sizing up to ensure a comfortable fit throughout the day.
Time of Day: For the most accurate result, measure your finger at the end of the day. Fingers are slightly smaller in the morning and when cold.
The Knuckle Factor: Ensure the size you choose can slide over your knuckle with slight resistance but without discomfort.
Width Matters: For wider bands (like our Chain Link Ring), some customers find a half-size larger more comfortable than their usual thin-band size.
