How to Measure Your Ring Size At Home

Buying a ring—whether it’s for yourself or someone else—can be tricky when you don’t know the right size. Visiting a jeweler isn’t always an option, but luckily, there's a simple and reliable way to find your ring size right from the comfort of your home. All you need is a strip of paper, a ruler, and a few quiet minutes.

Let’s break down the step-by-step process:

Step 1: Prepare What You’ll Need

Before you begin, make sure you have the following:

• A strip of paper about 10 cm long and 0.5 cm wide. You can cut this from any regular sheet of paper. Avoid stretchy or crinkled paper.

• A pen or fine marker to mark your measurement.

• A ruler with millimeter (mm) markings.

• A ring size conversion chart (you can easily find these online).

Make sure your hands are at a normal temperature, not too cold or warm, as finger size can slightly change with temperature.

Step 2: Wrap the Paper Around Your Finger

Take the strip of paper and gently wrap it around the base of the finger you want to measure. This should be the part of your finger where the ring will sit.

Hold the paper firmly but not too tightly. It should feel snug enough to stay in place, but not digging into your skin. Make sure the paper lies flat against your finger with no gaps or twists.

Step 3: Mark the Meeting Point

Once the paper strip fully circles your finger, use your pen to mark the spot where the end overlaps the rest of the strip. This is the circumference of your finger.

Pro tip: If your knuckle is significantly wider than the base of your finger, measure both and choose a size in between to ensure the ring fits comfortably over your knuckle and sits well at the base.

Step 4: Measure the Length in Millimeters

Now, remove the paper strip and lay it flat on a table. Use your ruler to measure the distance between the start of the paper and the mark you made. Write down this number in millimeters—this is the circumference of your finger.

For example, if the length between the start and your mark is 57 mm, that is your finger’s circumference.

Step 5: Convert the Measurement to a Ring Size

Using your millimeter measurement, refer to a ring size conversion chart to find the corresponding ring size. These charts will tell you what size (US, UK, or European) matches your finger circumference.

Here’s a rough guide to get you started:

Size	US Size	Finger Circumference (in mm)	Diameter of Ring (in mm)
S	9	59.5	19.0
M	10	62.1	19.8
L	11	64.6	20.6

Extra Tips for Accuracy

• Measure at the end of the day when your fingers are naturally a bit larger.

• Don’t measure your fingers when they’re cold—this can give you a smaller size than you need.

• If you're between sizes, it's usually safer to go a half size up for comfort.

• Repeat the process two or three times to make sure your measurement is consistent.
