Ring Size Guide
YOU ARE BUYING FOR YOURSELF
There are several methods for determining your ring size:
Measure an existing ring
- Find an existing ring that fits the desired finger.
- Measure the internal diameter of the ring.
- Use the chart below to determine your ring size
Measure your fingerThe best way to get the right fit is to ask your jeweler to measure your ring or your finger.
To measure your finger, the jeweler will use a set of finger gauges, often called a ring sizer.
To measure an existing ring, the jeweler will typically use a ring mandrel – a cylindrical tool – that is marked with ring sizes.
Your jeweler will also know how to factor in temperature, humidity, altitude and even time of day, which can also affect finger size.
If you can’t have your finger measured by a jeweler, you can
- Wrap a strip of paper around your finger, marking the place where you’d like your ring to be
- Take into consideration that the ring needs to be able to slip over the finger joint or knuckle. Very often, the joint is larger than the rest of the finger.
- Mark the spot where the paper meets and measure the distance with a ruler.
- Use the chart below to determine your ring size.
(Different countries use different scales to measure ring size. We make sense of these differing standards in our ring chart)
|US & Canada||5||5 1/2||6||6 1/2||7||7 1/2||8||8 1/2||9|
|UK & Australia||J 1/2||K 1/2||L 1/2||M 1/2||N 1/2||O 1/2||P 1/2||Q 1/2||R 1/2|
YOU ARE PLANNING A SURPRISE
- If you want to keep the element of surprise, you can always “borrow” a ring from their jewelry box and take it to a jeweler yourself.
- Another way to secretly estimate ring size is by using soap. Press one of their favorite rings (one she wears on their ring finger) into a bar of soap until it creates an impression. Bring the bar of soap to your jeweler, who can use the markings to determine their ring size.
- Ask their friends or family members if they know their ring size.
- Be mindful of weather, humidity, altitude and time of day: Fingers shrink in the cold and swell in the heat. Likewise, high and low humidity can cause a finger to swell or shrink.
- Buy a larger ring: It is easier to remove metal from a ring that’s too big than to add metal to a ring that’s too small.
- Shank size matters: Rings with wider shanks usually need to be a bit larger, as they will fit more snugly.
- Beads: Small gold balls can be added to the inside of a ring that’s too big to make it fit tighter and keep it from turning on the finger.
