Ring Sizing at Home
DECCLA Ring Sizer
Measure an Existing Ring
String Method

Our printable ring sizer offers the most straightforward approach to determining your correct size from the comfort of your home. Simply download and print the PDF, ensuring your printer settings are adjusted to actual size rather than scaled to fit.

For the most accurate measurement, we recommend using the ring sizer in conjunction with a ring you currently wear on the same finger. This dual approach allows you to verify your size through comparison, ensuring consistency and confidence in your selection.

If you already possess a ring that fits comfortably on your intended finger, this method provides an exceptionally reliable measurement.

Select a ring that you wear regularly and that sits properly on the specific finger where you plan to wear your new piece. Using a ruler with millimeter markings, carefully measure the inner diameter of the ring.

Once you have obtained this measurement in millimetres, consult our comprehensive conversion chart to identify your corresponding ring size.

Take a piece of non-stretchy string, thin ribbon, or a narrow strip of paper and wrap it comfortably around the base of your intended finger, ensuring it can slide over your knuckle. Mark the precise point where the string or paper overlaps, taking care not to pull too tightly or leave it too loose - the fit should feel secure yet comfortable.

Lay the string or paper flat and measure the marked length in millimeters using a ruler. This circumference measurement can then be referenced against our conversion chart to determine your ring size. For optimal accuracy, we suggest repeating this process two or three times and calculating an average of your measurements.

Sizing for Surprises
Borrow A Ring
Trace A Ring
Estimate and Resize Later

When selecting a ring as a surprise, discreetly borrowing one they already wear provides the most accurate sizing information. Choose a ring from the specific finger where the new piece will be worn, as ring sizes can vary significantly between different fingers.

Use our printable ring sizer to determine the exact size by placing the ring over the circles until you find the perfect match.

Measuring a ring they've chosen for comfort on that particular finger accounts for their personal preferences and the natural shape of their hand.

Tracing offers a practical alternative for determining ring size. Place one of their rings on a piece of white paper and, using a sharp pencil or fine-tip pen, carefully trace the inner circle of the band. Press the ring firmly against the paper to prevent any shifting that might compromise the accuracy of your tracing.

After completing your tracing, measure the diameter of the circle in millimetres using a ruler, then reference our conversion chart to determine the size.

When all other methods prove impractical, making an educated estimate remains a viable option.

When in doubt, selecting a slightly larger size is advisable, as reducing a ring's size is typically more straightforward than enlarging it.

With our complimentary resizing service available within three months of purchase, you can present the ring at your intended moment and have it professionally adjusted to achieve the perfect fit shortly thereafter.

Please note that certain designs, such as eternity bands, cannot be resized, so we recommend confirming resize eligibility before selecting this method.
