Method 1: The Paper/String Wrap (Measuring Your Finger)
This is the most common DIY method, perfect if you don't have an existing ring to go by.
What you'll need:
-
A thin strip of paper (about 6 mm wide) or a piece of non-stretchy string/dental floss
-
A pen
-
A ruler with millimetre (mm) measurements
Let's do it:
-
Prepare Your "Sizer": Cut a thin strip of paper or grab your string. It's important that it's thin, as a wide strip can give an inaccurate reading.
-
Wrap It Up: Wrap the paper or string snugly around the base of the finger you intend to wear the ring on.
-
Pro Tip: As you wrap, make sure it's snug but not uncomfortably tight. You also need to be able to slide it back over your knuckle – this is often the widest part of your finger!
-
Mark Your Spot: Use your pen to mark the exact point where the end of the strip overlaps itself.
-
Measure the Length: Lay the marked paper or string flat and use your ruler to measure the distance from the end to the pen mark in millimetres (mm). This measurement is your finger's circumference.
-
Convert to Size: Now, you can click and download Ring Size Guide. You’ll use your circumference measurement to find your corresponding ring size.
This method directly measures the circumference of your finger, which is a key component in ring sizing.
Method 2: The Existing Ring Trick (Measuring Internal Diameter)
Got a ring that already fits you perfectly on the finger you want to measure for? This method is incredibly accurate!
What you'll need:
-
A ring that fits the target finger comfortably
-
A ruler or measuring tape with millimetre (mm) measurements
Let's do it:
-
Choose Your Champion: Select a ring that fits perfectly on the specific finger you're measuring for.
-
Measure the Inside: Place the ring on a flat surface. Take your ruler and measure the internal diameter of the ring. That's the distance straight across the inside of the ring, from one inner edge to the opposite inner edge. Make sure you're not measuring the ring itself, just the empty space inside.
-
Convert to Size: Again, consult Ring Size Guide. You'll find a column for internal diameter (in mm) that will lead you to your ring size.
This method directly measures the space the ring occupies on your finger, providing a direct route to your size.
Method 3: The Printable Ring Sizer
Www.ozmantrends.com.au offer free, printable ring sizing guides. These often combine both methods in an easy-to-use format.
What you'll need:
-
Access to a printer
-
Scissor (cutting out a paper sizer)
-
A ruler (to verify scale)
Let's do it:
-
Print with Precision: Download a printable ring size chart. The MOST IMPORTANT step here is to ensure your printer settings are set to "Actual Size" . Use a ruler to verify the chart's printed reference scale (usually 10cm or a credit card outline) is accurate.
-
Choose Your Tool:
-
For an existing ring: Place your well-fitting ring over the circles on the chart until the inside edge of your ring perfectly matches one of the printed circles.
-
For your finger: Ring Size Guide includes a paper "ring sizer" strip that you cut out. You then wrap this strip around your finger and read your size directly from the scale printed on it.
The Ring Size Guide is calibrated to standard ring sizes, taking the guesswork out of conversion.

Essential Tips for Maximum Accuracy
-
Timing is Everything: Your fingers swell throughout the day. Measure your finger in the late afternoon or early evening when they are likely to be at their largest. Avoid measuring when your hands are very cold (fingers shrink) or very hot (fingers swell).
-
Mind the Knuckle: If your knuckle is significantly larger than the base of your finger, measure both. You need a size that can comfortably slide over the knuckle but isn't so loose it will slip off the base. When in doubt, it's generally better to size up slightly, especially for wider bands.
-
Measure Multiple Times: Don't rely on a single measurement! Do it 3-4 times to ensure consistency and eliminate any errors.
-
Dominant Hand Differences: Your dominant hand is often slightly larger than your non-dominant hand. Make sure you're measuring the correct finger on the correct hand for the ring you intend to wear there.
-
Band Width Matters: A wider band will feel tighter than a thin band of the same size. If you're planning on a very wide ring (6mm or more), you might consider going up half a size.
Knowing your ring size empowers you to shop for rings online with confidence, ensuring that every piece you choose will be a perfect, comfortable fit.
