💍How to Measure Your Ring Size

💍 Ring Sizing Tips - Choosing Your Ring Size Start by measuring the finger you’ll be wearing the ring on, rounding to the nearest whole millimetre. A well‑fitting ring should glide over the knuckle with a little resistance, feel secure once on, and still be easy to remove. For the most accurate result, use a plastic ring sizer or a correctly printed guide.

🕒 Measure at Different Times of Day Finger size naturally changes throughout the day due to temperature, hydration, and activity. Measure a few times — morning, afternoon, and evening — and use the average to find your ideal size.

📏 When in Doubt, Choose Slightly Larger Because fingers fluctuate in size, it’s usually safer to choose a ring that’s a touch bigger rather than too small. A slightly looser ring is far more comfortable than one that risks getting stuck.

💫 Wide Band Rings Rings with a wider shank fit more snugly. If you’re choosing a wide‑band design, go half to one size up from your usual fit for comfort.

🎁 Finding Someone Else A Ring Size (Without Spoiling the Surprise) 💍 Check Their Jewellery Borrow one of their rings — ideally one worn on the same finger — and measure the inner diameter with a ruler. This gives a close and reliable estimate.

🧵 Use a Piece of String Wrap a thin piece of string around their finger while they’re asleep, mark where it meets, and measure the length. Convert this into an accurate ring size using our ring guide.

👪 Ask Friends or Family Someone close to them may already know their size, or can help you compare discreetly.
