Finding the perfect size for a gold ring is the key to ensuring comfort, security, and a lifetime of enjoyment. Because your finger size can fluctuate daily, getting the measurement just right requires precision and a few simple tricks.
At Krasa Jewelry, we want your Moissanite or gold piece to fit flawlessly. Follow this guide to accurately determine your ring size, focusing on the factors that affect your fit.
I. The Critical Factors Affecting Ring Size
Before you measure, it’s vital to understand what can make your fingers swell or shrink:
|
Factor |
Effect on Ring Size |
Best Practice |
|
Time of Day |
Fingers are usually smaller in the morning and slightly larger/swollen in the evening. |
Measure in the late afternoon/evening when your fingers are at their largest, after you've been active. |
|
Temperature |
Cold temperatures make fingers shrink. Heat and humidity cause fingers to swell. |
Measure when your hands are at a comfortable, average temperature (not immediately after exercising or coming inside from the cold). |
|
Knuckle Size |
The ring must slide over the knuckle, which is often wider than the base of the finger. |
Measure both the base and the knuckle. If there's a big difference, choose a size in between the two, or slightly larger than the base measurement. |
|
Dominant Hand |
Your dominant hand (the one you write with) is typically half a size larger than your non-dominant hand. |
Always measure the exact finger on the hand where the ring will be worn. |
|
Band Width |
Wider rings (bands 6mm or thicker) feel tighter than thin bands, even if they have the same size number. |
For wider bands, consider sizing up half a size for a comfortable fit. |
II. How to Measure Your Ring Size at Home
For the most accurate results, use the string/paper method combined with a chart, or measure an existing ring.
Method 1: Measuring Your Finger Circumference
This method determines the circumference (the distance around) your finger in millimeters (mm).
-
Prep the Tool: Cut a thin strip of non-stretchy paper or string (about 10 cm long).2
-
Wrap: Wrap the paper or string snugly around the base of the specific finger you plan to wear the ring on.
-
Mark: Use a pen to mark the exact point where the paper or string overlaps. Ensure it fits over your knuckle comfortably.
-
Measure: Lay the paper/string flat and use a ruler to measure the length in millimeters (mm) from the starting edge to your pen mark.3 This is your circumference.
-
Convert: Use a standard ring size chart to convert your circumference measurement to the corresponding US/Canada ring size (e.g., 52 mm circumference = Size 6). If you fall between two sizes, always choose the larger size.
Method 2: Measuring an Existing Ring
If you have a ring that already fits the intended finger perfectly, use it as your guide.
-
Find the Fit: Select a ring that fits the target finger comfortably.
-
Measure Diameter: Place the ring over a ruler or measuring tape and measure the internal diameter (the distance straight across the inside of the ring) in millimeters (mm).
-
Convert: Match the diameter measurement to a ring size chart. For example, an internal diameter of 16.5 mm typically corresponds to a size 6 (US/Canada).
III. The Perfect Fit: What It Should Feel Like
A well-fitted ring should:
-
Be Snug: It should feel snug enough that it won't rotate easily or fall off when shaking your hand.
-
Offer Resistance: It should take slight resistance and a firm pull to slide the ring over your knuckle and off your finger.
Pro Tip: When in Doubt, Size Up Half a Size
It is almost always better to have a ring that is slightly loose than one that is too tight. A tight ring is uncomfortable, can be difficult to remove, and risks damaging the metal over time.
