Ring between sizes — size up or down?
Between two ring sizes, compare the actual adjacent sizes before ordering. Neither rounding up nor down guarantees a secure, removable fit.
Between-sizes advisor
Choose the two sizes you are between and the fit factors that usually decide up or down.
This advisor uses editorial rules to suggest sizes to try. Its adjustments have not been validated by a wearer study and are not manufacturer sizing instructions. Compare the same width and inner profile with a jeweler.
Ring fit fix advisor
Choose the fit problem and get the safest next step before resizing, replacing or buying another ring.
Compare both candidates
Try the smaller and larger sample on the intended finger. Check passing the knuckle, comfort at the base and whether normal hand movement lets the ring slip off. Tell the jeweler if neither candidate works.
Keep the comparison fair
Use the same band width and inner profile for both samples. A narrow sizing ring and a wide finished band are not equivalent trials. Confirm exchange or resizing terms before engraving.
Why two charts can differ
Benchmark’s guide recommends a half US size increase for its rings wider than 5 mm. Its comfort-fit advice instead rounds down between sizes, with a large-knuckle exception. This is a manufacturer-specific example, not a rule for every ring.
