Whether you're treating yourself to a new statement piece or planning a secret proposal, getting the size right shouldn't feel like a high-stakes guessing game.
In this guide, we're breaking down the easiest, most accurate ways to find your ring size at home so you can shop with 100% confidence.
1. Measuring Ring Size with Our Printable Ring Size Chart
Discover your ring size quickly and accurately with our Printable Size Chart PDF. This all-in-one guide includes a global conversion table to ensure you order with confidence every time and everywhere.
To get started, simply download the chart and follow our easy three-step measurement process below.
Step 1: Print at Full Scale (100%)
Do not resize the page or use "Fit to Page" settings. Accuracy is vital, so we've included a reference line to help you confirm the chart is printed to the correct millimeter scale before you begin.
Step 2: Measure Your Ring Size or Finger Size
Method A: Measure an existing ring
-
Choose the Right Ring: Pick a ring that fits the target finger comfortably. To ensure an accurate match, use a piece that is worn on the same finger (and hand) as the new ring you’re ordering.
-
Match your current ring to the circles: Place your ring on the chart until the inside edge matches one of the circles seamlessly. The number within that circle reflects the inside diameter and identifies your correct ring size.
Method B: Use Ring Sizer to Measure Finger
Cut out the Ring Sizer Template. With a straight edge razor, carefully cut the indicated slot across the dotted line. Insert the end of the sizer into the slot, so that the numbers are on the outside of the circle. Place the sizer on the intended finger at the widest point and pull the tab through the slot until the sizer is snug. Make certain it can still slip over the knuckle of the finger. The number that lines up with the slit is your ring size.
Step 3: Convert Size for Different Regions
Don't let different sizing systems get in the way of your perfect ring! If you already know your size in a different region, check our International Size Conversion Table to find your match in seconds.
Steps to Convert Your Size:
-
Find Your Region: Look for your local sizing system in the header.
-
Cross-Reference: Slide your finger across to find the equivalent size for the region you are shopping in.
-
Check the Millimeters: If you're unsure, the "Diameter" is the most reliable universal measurement.
Pro Tips:
- If you're between sizes, always choose the larger option for a more comfortable fit.
- Ring width matters! Wider styles naturally feel tighter, so we recommend ordering a half-size larger than your standard measurement for the best experience.
- Always measure the specific finger the ring is intended for.
- Once you get your new ring, put the ring on and shake your hand over a bed or sofa. If the ring stays put, it's perfect. If it slides past the knuckle, it's too big and needs a quick adjustment.
2. How to Measure Ring Size with String, Paper, and a Ruler
No printer? No problem. This classic DIY method uses common household items.
-
Wrap It: Cut a thin strip of paper or a piece of non-stretchy string. Wrap it snugly around the base of the finger you intend to wear the ring on.
-
Mark It: Use a pen to mark the exact point where the end meets the rest of the string/paper.
-
Measure It: Lay the string flat against a ruler and measure the distance in millimeters (mm). This is your finger's circumference.
3. How to Secretly Get a Ring Size
Planning a surprise? You'll need to be a bit of a jewelry detective. Here are smart ways to find out their ring size without raising any eyebrows.
-
The "Borrow & Trace" Method: Sneak a ring they already wear frequently. Place it on a piece of paper and carefully trace the inside circle of the ring with a sharp pencil. Take that drawing to a jeweler or compare it to a printable chart. (Crucial tip: Make sure you know which finger they wear that specific ring on!)
-
The Soap Impression: If you only have a few seconds, press one of their favorite rings into a bar of soap to create a mold. A jeweler can use this indentation to determine the exact size.
-
The "Try It On Yourself" Trick: Slide their ring onto your own finger. Push it down as far as it will comfortably go and draw a line on your finger with a pen right where the ring stops. Head to a jeweler and have them measure your finger at that exact line.
-
Ask their inner circle: Best friends, siblings, or mothers often know this secret information. They can casually bring it up in conversation without raising suspicion.
-
The Sleep Sizer: If they are a heavy sleeper, you can try the string method while they snooze—just be stealthy!
4. The Best Time of Day to Measure
Believe it or not, your fingers change size throughout the day. To get the most accurate measurement:
-
Measure at the end of the day: Your fingers are typically at their largest in the late afternoon and evening.
-
Measure when your hands are warm: Never measure right after coming in from the cold (fingers shrink) or a hot shower (fingers expand). Room temperature is your friend.
-
Measure 3 to 4 times: To be absolutely certain, measure your finger at a few different times on different days to see if the size fluctuates.
-
Avoid Salt and Caffeine: Both can cause temporary swelling.
5. Frequently Asked Questions (FAQ)
Q: What if I have large knuckles?
If your knuckle is significantly larger than the base of your finger, measuring only the base will result in a ring you can't actually put on.
Measure both the base and the knuckle, then choose a size right in the middle. This ensures the ring slides on with a little resistance but stays secure once it's in place.
Q: Do ring sizes vary by brand?
While most jewelers follow standard sizing, slight variations can occur—much like shoe sizes.
Additionally, the "Comfort Fit" style (where the inside of the band is domed rather than flat) often feels about a half-size larger.
Always check if a brand has its own specific size chart before ordering.
Q: Should I size up or down if I'm between sizes?
When in doubt, always size up.
It is much easier (and cheaper) for a jeweler to add a small "ring guard" or "sizing beads" to a loose ring than it is to stretch or rebuild a ring that is too small.
Q: Does the width of the band affect the size?
Yes! A wider band (anything over 3mm) takes up more space on your finger and will feel tighter than a dainty, thin band.
If you are buying a wide statement ring or a stacking set, we recommend going up half a size from your normal measurement.
