What You Need to Measure Your Ring Size
You only need a few simple tools to measure your ring size accurately.
Tools to Gather
- A ruler: with millimetre markings
- Paper or string: a thin strip that does not stretch
- A pen to mark the measurement
- A ring that already fits, if you have one
Measure in millimetres rather than inches, as it is much more precise. Avoid stretchy materials like elastic or thick paper, as they can give a ring size that is too big.
Method 1: Measure a Ring That Already Fits
This is the most reliable at-home method if you already own a ring that fits the finger you want to wear the new ring on.
How to Measure
- Place the ring on a flat surface
- Measure the inside diameter straight across the centre
- Note the measurement in millimetres
- Match it to the ring size chart below
Measure the inside edge only, not the outside. Your ring size can differ between hands and fingers, so measure a ring from the same finger where possible. This method is ideal for everyday styles like stacker rings.
Method 2: Measure Your Finger
No ring to measure? You can measure the circumference of your finger instead.
How to Measure
- Wrap a thin strip of paper around the base of your finger
- Mark where the paper overlaps
- Lay it flat and measure the length in millimetres
- Compare the circumference with the chart below
The paper should feel snug but not tight, and should still slide over your knuckle. If it slips off easily, your ring size will be too large, so measure again.
Common Mistakes
- Pulling too tight: this gives a ring size that is too small
- Measuring cold fingers, which shrink in cooler weather
- Forgetting the knuckle if it is wider than the base of your finger

Tips for an Accurate Ring Size
Fingers change size through the day, so a little care gives a more accurate ring size.
- Measure late in the day: fingers are usually at their largest
- Avoid measuring after exercise, a hot shower or when very cold
- Measure two or three times and use the most consistent result
- Check the ring will slide over your knuckle
Summer heat and travel can make fingers swell slightly, so if you live somewhere warm, measuring on a warm afternoon gives a realistic ring size for everyday wear.
Should You Size Up or Down?
If your measurement falls between two sizes, the right choice depends on the band width and your knuckle.
- Wide bands: size up, as wider rings feel tighter
- Thin bands: your true size usually feels best
- Large knuckles: size up so the ring slides on comfortably
- Stacking rings: a snug fit stops them spinning
A ring that is slightly loose is easier to fix with a sizing bead than one that will not fit over your knuckle. Explore our guide to the best sterling silver rings for women for more fit tips.
Finding a Ring Size for a Gift
Buying a surprise ring? You can still find the right ring size without asking.
- Borrow a ring: measure one she wears on the same finger
- Trace the inside of a ring on paper and measure the circle
- Ask a close friend or family member
- Choose an adjustable style if you are unsure of her ring size
