You have found a beautiful ring and can already see it perfectly among your other favorites. All that is left is to choose the right size. But how do you know whether you need size 16, 17 or 18?
Fortunately, you can very easily measure your ring size at home. All you need is a ruler and a ring that already fits well. Or a piece of paper or thread if you do not have a suitable ring.
We will show you two easy ways and give you a few more handy tips. Then you can simply order that lovely ring!
1. Measure your ring size with a ring you already have
1.Do you already have a ring that fits comfortably on the finger you want to wear your new ring on? Then this is the easiest way.
- Place your ring on a flat surface.
- Place a ruler exactly across the middle.
- Measure the inside of the ring, from inner edge to inner edge.
- Read the measurement in millimeters.
Do you measure 17 mm? Then you have ring size 17 at Just Good Jewellery.
Make sure you are measuring the inner diameter. The outer edge does not count, otherwise you will end up with a size that is too large.
2. Measure your ring size with a piece of thread or paper
No suitable ring nearby? Then take a thin piece of thread or a narrow strip of paper.
- Wrap it around the finger you want to wear the ring on.
- Make sure it fits well, but do not pull it too tight.
- Mark where the paper overlaps or where the ends of the thread meet.
- Place it along a ruler and measure the length in millimeters.
That length is the circumference of your finger. In the size chart below you can see which ring size corresponds to it.
Our tip: make sure you can still easily move the thread over your knuckle. Your ring will naturally have to fit over it as well.
Ring size chart: which size do you need?
| JGJ ring size | Inner diameter | Finger circumference (rounded) |
| 14 | 14 mm | 44 mm |
| 15 | 15 mm | 47 mm |
| 16 | 16 mm | 50 mm |
| 17 | 17 mm | 53 mm |
| 18 | 18 mm | 57 mm |
| 19 | 19 mm | 60 mm |
| 20 | 20 mm | 63 mm |
| 21 | 21 mm | 66 mm |
Have you measured an existing ring? Then look at the inner diameter column.
Have you used a piece of thread? Then look up your measured length under finger circumference.
The sizes are rounded. If you measure, for example, a circumference of 53 mm, you will end up with ring size 17.
How do you know if your ring fits well?
A ring should, of course, fit comfortably. Not so tight that it pinches your finger, but also not so loose that you are afraid of losing it.
A well-fitting ring slides over your knuckle with a little resistance and then sits comfortably on your finger.
Also try taking it off. It may require a little effort, but of course you do not have to pull on your ring as if it were stuck.
And move your hand for a moment. The ring may move slightly with it, but it should not easily slide off your finger.
Do you have somewhat wider knuckles? Then take that into account when choosing the size. After all, your ring must also be able to come off easily.
When is the best time to measure your ring size?
We would prefer you to measure your ring size later in the day, when your hands are at a normal temperature.
Your fingers can be slightly thinner when it is cold and a little thicker when it is warm. Your size can also vary slightly during the day.
Therefore, feel free to measure two or three times, possibly at different times.
Do you always get approximately the same size? Then you have a good indication of which ring size you need.
And if you are using a piece of thread? Make sure it fits well without pressing into your skin.
Are you torn between two ring sizes?
Suppose you measure a size between 17 and 18. Which one do you choose?
In that case, we would usually go for the larger size, especially with a somewhat wider ring.
Wide rings can feel a bit tighter than delicate, narrow models.
But also consider how you prefer to wear a ring. Do you like it snug around your finger? Or do you prefer a little more room to move?
As long as the ring easily goes over your knuckle and does not slide off your finger, you will usually be fine.
Giving a ring as a gift? Here is how you find out the size!
Do you want to surprise your sister, mother or best friend with a beautiful ring, but have no idea what size she wears?
Maybe you can measure a ring she already wears. Just make sure it is worn on the same finger she would wear her new ring on.
And if that does not work? Then an adjustable ring can be a handy choice, if the chosen design has that option.
This way you do not have to guess a size.
