Your ring size can change over the years because hands change. Weight, pregnancy, the weather, and the passing of time can all make a ring that once fitted well feel tighter or looser. A change in how the ring feels is often a change in the hand, not a fault in the ring.
This is a longer view than the short tightness you might feel after a flight or on a hot day, which we cover in our guide to warm weather and flights, and in our note on winter, gloves and ring fit. Over years, the change can last, and it may be worth looking at the size again.
The sorts of change that are common
Fingers are not a fixed measurement. A change in weight, a more active job, or simply getting older can alter how a knuckle sits and how a ring passes over it. The weather still plays a part from season to season. None of this is a precise medical rule, and hands vary. It is simply a reason to treat a new tightness, or a new looseness, as something to watch rather than to ignore or to panic over.

Pregnancy, and other times of swelling
During pregnancy, some people's hands swell, and a ring that was comfortable can become tight. Do not force it off, and do not force it on. For a time, the ring can sit on a chain, or on another finger, which is also the idea behind a ring keeper necklace. A midwife or doctor is the right person for medical questions. We are not a medical service, and we would rather you were comfortable and safe than determined to keep the ring on every day. A resize is often better considered after the hand has had time to settle, if the design can be resized.

When a resize is worth considering
If the tightness or looseness only appears in heat, in cold, or after a long day, the size may still be right for ordinary hours at home. If the ring often feels tight in a cool room, leaves a deep mark, or spins and slips, it is worth checking the size more calmly. Our guide to checking a UK ring size at home explains methods without turning it into a hasty decision. If a ring will not pass a knuckle, stop, as we note in our guide to what to do if a ring does not go on easily.

What we can do, and what we cannot promise
If the design can be resized, we can often help. We include one free resize within 1 month of delivery, provided the design allows it, and we can talk about later changes too. Some styles, including many full eternity bands, cannot be resized in the same way, which we discuss when the design is agreed in writing. Get in touch and we will look at it with you. We work by video consultation and message, with no showroom. If you are still commissioning a ring, making takes 5 to 6 weeks after written approval of the CAD and the stone, and you can look at stones in our diamond collection.
Frequently asked questions
Why can your ring size change over the years?
Hands change. Weight, pregnancy, the weather, and the passing of time can all make a ring that once fitted well feel tighter or looser. A change in how the ring feels is often a change in the hand, not a fault in the ring.
Should you resize a ring as soon as it feels tight?
Not at once, if the tightness is new or comes and goes. Heat, a long day, or a period of swelling can ease. If the ring is often tight at home, in a cool room, it is worth checking the size more calmly.
What if a ring feels tight during pregnancy?
Do not force it. Some people wear the ring on a chain, or on another finger, until things have settled. A midwife or doctor is the right person for medical questions. A resize is often better considered after the hand has had time to settle, if the design allows it.
Can every ring be resized if your size has changed?
No. We include one free resize within 1 month of delivery if the design can be resized, and we can often help later as well, but some styles, including many full eternity bands, cannot be resized in the same way.
