How to Find Your Ring Size at Home

When buying a ring, especially as a special gift, a perfect fit matters as much as a beautiful design. A ring that pinches or is loose enough to slip off directly spoils the comfort of wearing it. Knowing how to find a ring size lets you choose correctly even before you go to the shop.

You can measure with simple tools at home. Ring sizes are based on millimetre measurements. Whether it is for your own finger or a surprise for someone you love, using the right technique gives a result very close to a jeweller's measurement.

Outside factors to keep in mind

Our fingers get slightly thinner or thicker during the day depending on temperature, how much we drink and physical activity. Early in the morning or in cold weather fingers shrink a little, while in hot weather or later in the day they may swell. For the most accurate size, measure in the middle of the day when your body temperature is normal.

Finger thickness also usually differs between the right and left hands. Fingers on your more active hand may measure a little wider. Measure the finger on which you plan to wear the ring.

Finding your size with the diameter method

One of the most reliable ways to measure at home is to use a ring that already fits the finger perfectly. The method is very similar to the one described in our guide how to measure your bangle size. Make sure the reference ring is not dented and keeps a perfectly round shape.

Lay the ring on a flat surface. Place a millimetre ruler so that it passes exactly through the centre. Without counting the thickness of the metal, measure the distance between the two widest points on the inside. This is the ring's inner diameter. Compare it with the size chart below to find the right size.

Measuring your finger circumference

If you have no suitable reference ring, measure around your finger directly. Use a non-stretch string, a ribbon or a thin strip of paper. Wrap it around the finger you plan to wear the ring on, so it sits at the base of the finger. Make sure it is not tight, but not loose either.

Mark the point where the two ends meet. Then lay the string flat and measure up to the mark with a ruler. The result is your finger circumference in millimetres. Match this length to the chart to find your size. To choose a new design, browse the models in our catalogue.

Tricks for finding a size secretly for a surprise

For a proposal or a special birthday gift, finding the size secretly is the hardest part. To keep the surprise, your first choice should be to borrow a ring from the right finger out of the person's jewellery box for a short time and use the diameter method.

Another way is to put the ring on a sheet of paper and draw a thin circle around the inside with a pencil. A jeweller can estimate the size by measuring the diameter of that circle. If you are unsure, drop into our store for help; our address is on the contact page.

A strategy for wider knuckles

For some people, the difference between the base of the finger and the knuckle is marked. If the knuckle is much wider than the base, it is harder for the ring to pass over it. Base the size only on the base of the finger and the ring may not go on; base it only on the knuckle and it will be loose at the base and keep turning.

If your fingers are like this, measure twice: once over the knuckle and once at the base. Choosing a size close to the average of the two usually gives the most balanced result. The ring will pass over the knuckle with a little effort but sit steadily at the base without too much space.

Ring numbers used in Turkey are based on the finger circumference in millimetres. Match your measurement with the table below to confirm your size.

Resizing

Despite all these calculations, small deviations in ring size are normal. Gold lends itself well to workshop work, and many gold rings can be made a little bigger or smaller depending on their design and stones.

Plain wedding bands and simple models can usually be adjusted to the finger easily in the workshop. But if the ring is set with stones all the way round or has delicate craftsmanship, resizing can spoil the design. That is why getting the size right from the start matters with full eternity models.

Frequently Asked Questions

Can ring size be estimated from height and weight?

Height and weight give an idea of general build but do not determine finger thickness. A slim person may have wide knuckles, and a larger person may have slim fingers. Measuring is essential to find the right size.

Can a ring be resized later if it is too tight or loose?

Many plain gold rings can be made slightly bigger or smaller in the workshop. With models set with stones all the way round or heavily patterned, resizing is usually not recommended because it can spoil the design.

Which is more accurate, diameter or circumference?

A diameter measurement taken from a ring that fits perfectly usually has a smaller margin of error. With a string or paper, pulling it too tight or leaving it loose can cause small errors.

What is the most common ring size?

It is not right to talk of a single average size, because finger shape varies greatly from person to person. That is why you should measure rather than guess. At a jeweller, sizing rings find the right number in a few minutes.
