Finding your perfect ring size is one of the most important steps when purchasing a ring—especially if it’s a gift, an engagement ring, or a custom piece made just for you. A properly fitted ring should feel comfortable and secure: snug enough that it won’t slip off, but loose enough to slide over your knuckle without struggle.
Here’s everything you need to know about determining your ring size accurately.
1. Measure at the Right Time of Day
Our fingers naturally change size throughout the day due to temperature and activity. They tend to be slightly smaller in the morning and larger in the evening or after exercise.
Tip: Measure your finger at the end of the day when it’s at its largest. This ensures your ring will be comfortable all day long.
2. Consider the Weather
Cold temperatures cause fingers to shrink slightly, while heat can make them swell. If you’re measuring your size in the middle of winter, keep in mind your ring may feel tighter come summer.
Tip: Aim to measure in a moderate room temperature environment for the most accurate result.
3. Use a Ring Sizer or Visit a Jeweller
The most accurate way to determine your ring size is to use a professional ring sizing tool or to visit your local jeweller. They can quickly measure your finger and even account for ring style and band width.
If you can’t visit a jeweller, you can purchase an inexpensive plastic ring sizer online or request one from your favourite jewellery store.
4. Measure an Existing Ring
If you already own a ring that fits perfectly on the intended finger, you can use it as a guide. Simply measure the inside diameter of the ring using a ruler or caliper and compare it to a standard ring size chart.
Tip: Make sure the ring you’re measuring matches the same finger and hand—our dominant hand’s fingers are often slightly larger.
5. Use the String or Paper Method (for Quick Estimates)
If you’re at home and need a quick size estimate:
-
Cut a thin strip of paper or use a piece of string.
-
Wrap it snugly around the base of your finger.
-
Mark where it overlaps, then measure the length in millimetres.
-
Compare that measurement to an online ring size chart.
Note: This method isn’t as precise as a jeweller’s measurement, but it can help you get close to the right size.
6. Think About the Ring Style
The width of the band affects how a ring fits. Wider bands often feel tighter and may require you to go up by half a size, while thinner bands are more forgiving.
Also, rings with larger stones or elaborate settings may fit differently, especially if you plan to wear them alongside other rings.
7. Factor in Comfort Fit Designs
Many modern rings feature a comfort fit—a slightly rounded inner surface that makes the ring easier to slide on and off. If you’re ordering a comfort-fit ring, you may need to size down slightly compared to a flat-fit band.
8. When in Doubt, Ask the Experts
If you’re unsure or in between sizes, it’s always best to consult a professional jeweller. They can help you find the perfect balance between comfort and security—and ensure your new ring fits beautifully for years to come.
