How to measure the size of your ring finger
Can I measure the size of my ring finger at home?
When it comes to measuring the size of your ring finger, there are plenty of methods out there for getting the most accurate ring size measurements possible. These can be done with common household objects, too. Before you start measuring your ring finger – or any finger – there are some important considerations to take into account first.

These metrics can be a little confusing. If you’re feeling a bit stuck, you can take a look at our conversion chart, which provides a clear conversion between US and UK metrics.
Methods for measuring your ring finger
If you’re measuring your ring finger in the comforts of your own home, you can use the string or paper test to obtain the most accurate measurement.
The string test
Whether it’s string or tooth floss, the ‘string test’ is one of the most common – not to mention accurate – ways to measure your ring size. It’s easy to measure and lets you play around with the fit to make sure the measurements are comfortable and snug.
The paper test
Very similar to the string test: cut a very thin strip of paper (one that may mimic the width of a ring) and use it to measure your ring finger. This one can be a little tricky though, especially as the paper sometimes won't hug your finger unless you pull it very tight.
How to measure your ring finger with string or paper
To measure your ring finger with string, tooth floss, or a strip of paper, here’s what you need to do:
Cut the string, floss or paper to measure at least 3 inches long
Wrap or tie the string or paper around the base of your knuckle
Grab a pen or pencil and mark where the string or paper overlaps
Measure the length of the string or paper and where you’ve made the mark on your ruler and convert it using our conversions chart
Using a ring that you already own that fits
Buy your own ring sizer
When all else fails, you can always purchase your own ring sizer – and we happen to have one of the best. That way you know exactly what yours or your partner’s ring size is without having to use any paper, string, a ruler or conversion chart.
Things to consider when measuring your finger
Also, make sure that you consider the size of your finger joints. If you know that your knuckles tend to be difficult to slip rings over, we recommend ordering a ring that’s a half-size larger than your measurement so it can slip on with ease.
How to measure your partner’s ring finger without them knowing
Let’s face it: if you’re ordering a custom engagement ring for your loved one, getting their ring size wrong could put you and your jeweller in a rather awkward position (luckily, we can resize rings in most circumstances).
If you’re shopping for your partner’s ring finger, it can feel a little awkward trying to get their measurements, not to mention almost impossible to be subtle about it. Here’s a few tips for measuring your partner’s finger as discreetly as possible.
Ask a confidant for help
Try asking your partner’s best friend, sibling, even their parents – they can help give you an idea what your partner’s ring size is, or help measure their ring finger without giving away the surprise.
Measure a ring from their jewellery collection
If you can sneak away a ring for the day and bring it to your jeweller, they’ll be able to size up the ring to fit your partner’s wedding ring as accurately as possible. Otherwise, you can always measure the ring with a ruler as mentioned above.
Try and compare fingers
This one may be a little fiddly, but it’s probably a great conversation point for ‘measuring your fingers’. Be sure to act as casual as possible so you don’t give it away!
