Ring size for a wide band
A wide ring can feel tighter than a narrow ring with the same size label. Determine the size using a sample with the intended width, not a universal numerical addition.
Wide-band size calculator
Estimate the order size for a wider band, then confirm before buying a non-resizable ring.
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.
Sources checked for the scope described here. Tool adjustments are editorial estimates, not measured fit outcomes or retailer quotes; specialist and native-language sign-off remain separate.
Ring fit fix advisor
Choose the fit problem and get the safest next step before resizing, replacing or buying another ring.
Start with the intended width
Ask for the finished band’s width in millimetres and compare a sample of that width. If several rings will be worn together, try the actual combination rather than treating each narrow band in isolation.
Choose a candidate, then test it
The calculator suggests an editorial trial range. Use it to plan which samples to request; order only after checking the model’s own sizing guide and a comfortable fit over the knuckle.
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.
