Getting your ring size right is one of the most important steps before purchasing a ring — whether it is an engagement ring, a platinum wedding band, or an everyday jewellery piece. This guide covers everything you need: Malaysia's HK ring sizing standard explained, three accurate at-home measurement methods, a complete ring size chart with US conversion, and expert tips for special occasions including surprise proposals.
In Malaysia, most jewellers — including Diamond & Platinum — use the Hong Kong (HK) ring size system, the recognised standard across Southeast Asia. Each HK number corresponds to the ring's inner circumference in millimetres: the higher the number, the larger the ring. If you have shopped internationally, the US size system uses a different scale based on inner diameter — the chart below includes both columns for easy cross-reference.
Measure in the afternoon at room temperature, on the correct finger and hand. Repeat three times and use the average.
Recommended — most accurate DIY method
Step 1 Cut a strip of paper approximately 1 cm wide and 10 cm long. Do not use elastic string or ribbon — these stretch and give inaccurate readings.
Step 2 Wrap the strip snugly around the base of the finger you wish to measure.
Step 3 Mark clearly where the paper first overlaps with a fine-tip pen.
Step 4 Lay the strip flat on a ruler and measure from the end to your mark in millimetres — this is your inner circumference.
Step 5 Repeat three times, average the readings, then match to the Circumference column in the D&P Ring Size Chart in Section 3.
Best for buying a surprise gift when you have access to one of the recipient's rings
Step 1 Select a ring the recipient wears comfortably on the intended finger and hand.
Step 2 Place it on a flat surface and measure the inner diameter — the straight-line distance across the inside — in millimetres with a ruler.
Step 3 Match to the Diameter (mm) column in the ring size chart below.
Important: Use a ring worn on the same finger and hand where the new ring will be worn.
Most accurate at-home method — recommended for engagement rings and wedding bands
Diamond & Platinum offers a complimentary ring sizer delivered free to your door across Malaysia. Loop it around your finger, adjust until it sits snugly at the base, and read your HK size directly from the scale.
The table below is the official Diamond & Platinum ring size chart, covering HK sizes 5 through 30. Use the Circumference (mm) column if you measured using the paper strip method. Use the Diameter (mm) column if you measured the inside of an existing ring. The US & Canada column allows you to convert from an international size you may already know.

An engagement ring is one of the most significant and personal pieces of jewellery a person will ever wear. The most accurate approach is to visit a Diamond & Platinum boutique together for a professional fitting, where our consultants can advise on ring style, diamond selection, band width, and the ideal size for your finger shape. Our Diamond 4Cs Page is also an excellent starting point for understanding the 4Cs — cut, colour, clarity, and carat — before your visit or purchase.
If a surprise proposal is planned, the following methods are the most reliable:
Wide wedding bands fit more snugly — consider sizing up by half a size. Visit a Diamond & Platinum boutique for a paired fitting if selecting bands together.
Most women wear between HK 10 and HK 15, with HK 12 (US 5.5) the most common. Most men wear between HK 16 and HK 21, with HK 18 (US 8.25) the most typical. Always measure accurately rather than relying on averages.
Use the paper strip method (Method 01): wrap a 1 cm wide strip around your finger, mark the overlap, and measure the length in millimetres. Match to the Circumference column in the ring size chart. Measure three times and average the readings, in the afternoon at room temperature.
HK sizes correspond to the ring's inner circumference in millimetres (e.g. HK 13 = 52.1 mm). US sizes use a different scale based on inner diameter. HK 13 = US 6; HK 22 = US 10. The D&P chart includes both columns for easy conversion.
Always choose the larger size. A ring that is slightly loose is more comfortable and easier to resize than one that is too tight. For wide bands (5 mm+), size up by half a size as these fit more snugly regardless.
Wide bands (5 mm and above) cover more surface area and fit more snugly than narrow rings of the same nominal size — often feeling half a size smaller. Always size up by half a size when purchasing a wide wedding band for all-day comfort.
