The most nerve-racking part of a proposal is often "will the ring fit?" Too loose and it slips off; too tight and it won't go on. This guide shows you how to measure ring size, including how to do it discreetly without tipping off your partner, plus how Hong Kong ring sizes compare.
How Hong Kong ring sizes work
Hong Kong commonly uses the "HK#" ring size, often cross-referenced with US sizes. Sizing systems can vary slightly between brands, so confirm the standard before buying. Roselle Jewelry's ring sizes cover the common HK and US ranges.
Ways to measure ring size
Method 1: use an existing ring
Take a ring your partner already wears on the target finger and measure its inner diameter (mm), then match it to a ring size chart. This is the most accurate and discreet method.
Method 2: string or paper strip
Wrap a thin string or paper strip around the finger, mark where it overlaps, and measure the length (the inner circumference), then match the chart. Make sure it can pass the knuckle.
Method 3: professional in-store sizing
The most accurate method is a professional ring sizer. If convenient, visit together, or stop by yourself first.
Discreet sizing tips (for a surprise proposal)
- Borrow an existing ring: while it's not being worn, borrow a ring from the target finger to measure or trace.
- Trace the inner circle: gently press the ring on paper to trace the inner circle, or measure the diameter as in Method 1.
- Ask those close to them: family or close friends may know the size.
- Leave some room: if unsure, size up slightly — resizing smaller is usually easier than larger, and Roselle Jewelry offers resizing.
Measuring precautions
- Timing: fingers change slightly through the day; evening is usually most accurate (fingers slightly fuller).
- Temperature: cold weather or just after exercise makes fingers smaller — avoid measuring then.
- Knuckle: the ring must pass the knuckle; a larger knuckle may need slight adjustment.
Unsure of the size? Don't worry. Roselle Jewelry offers resizing — after the proposal, visit our Tsim Sha Tsui or Causeway Bay boutiques to adjust to the perfect fit. Start by browsing our engagement rings.
Frequently asked questions
What if I don't know my partner's ring size?
Borrow an existing ring to measure its inner diameter, or size up slightly and adjust in-store later. Roselle Jewelry offers resizing after the proposal.
Can a ring be resized larger or smaller?
Most rings can be resized; smaller is usually easier than larger. It depends on the design — have a consultant assess it in-store.
When is the best time to measure?
Evening is most accurate, as fingers change slightly through the day; avoid measuring in cold weather or just after exercise, when fingers are smaller.
How do HK and US ring sizes compare?
Hong Kong uses HK# sizes, cross-referenced with US sizes. Systems can vary slightly between brands, so confirm the standard before buying; in-store measuring is most accurate.
