How do I find my ring size?
For the most accurate ring fit, we always recommend having your size measured professionally. Ring sizes can come down to fractions of millimetres, so it's important to be sized accurately.
If you’re in local to Toronto, feel free to book an appointment to visit our office to be sized.
If you’re elsewhere, a reputable local jeweler can measure your ring size, often as a complimentary service.
We don’t offer ring size testing tools, as we have found them to be inaccurate. For the best fit, we highly recommend having your ring size measured in person, either with us or at another reputable jeweler in your area.
Variables Affecting Ring Size
Several factors can influence your ring size, including body temperature, weather, hydration, salt intake, and hormones. To ensure the most accurate fit, we recommend measuring your finger at different times of day and taking an average. Keep in mind that fingers are often slightly smaller in winter and larger in summer, so temperature changes can impact sizing.
Band Thickness
The width of a ring band can also affect how it fits. Rings 3 mm or wider may require sizing up by a quarter or half size. Most Castlefield Collection rings fall between 1.8 mm and 3 mm, which means they generally fit true to size. For the best results, try on a band of similar width to the ring you plan to purchase when determining your size.
Ring Stacking
When stacking two or more rings, they will naturally feel a bit snugger on your finger. To ensure the most comfortable fit, we recommend trying the rings together with similar width to the ones you plan to wear when determining your size.
