Tips for the Perfect Fit

There are a lot of factors that can impact ring measurements. Finger widths naturally fluctuate, so to get the most accurate ring size it is a good idea to take multiple measurements throughout the day. You should account for factors than can affect sizing like:

Temperature

Keeping temperature in mind can help you get a better fit. Anyone who regularly wears rings has probably noticed that fingers naturally expand slightly in the heat and shrink smaller in the cold. For a snug fit in any weather, it is a good idea to average your ring size based your finger width in cold, normal, and warmer temperatures.

Happiness

Folklore says that wearing pearls on your wedding day will bring a happy marriage. Some believe a pearl is a representation of a tear and by wearing pearls, you ensure a lifetime of joy with your future spouse. This superstition is practiced by many brides who hope not to shed any tears in matrimony.

Finger Shape

Each finger is shaped differently, so make sure you closely measure the finger that is wearing the ring. Also, do not forget to measure your knuckle too so the ring can pass over and fit correctly at the base of your finger.

Your Diet

A factor that you may not even realize can affect ring size comes can be what you eat. For some people, too much salty food can actually cause fingers to swell.

When you are starting fresh, get your ring size right by following these steps.

Get a small piece of string, strip of paper, or print out our paper ring sizer tool.
Wrap the tool snugly around your finger, it should be comfortable and not squeezing too tightly.
Mark your tool. Then lay it out taut to measure with a ruler or compare with our sizing chart.
Do this process again to double check your measurements are accurate.

Yes! We offer ring resizing as one of our many Jewelry Repair services. You can book an appointment with our expert jewelers at a Zales store near you for an assessment and repair plan to resize your ring so it fits appropriately on your finger.

Your finger size will naturally fluctuate in the hot and cold, but you don’t want your ring to slide off or get stuck on your finger. Here are our suggested solutions for temperature-related fit problems:

In the cold: If your ring spins but stays on your finger, there are slight adjustments that can be made. Ask a Zales jeweler about ring beads or fold-over devices that can fix slight fit issues. However, if it is fully sliding off your finger you may need to resize the ring.
In the heat: Swelling around your ring can happen in hot weather and can be a minor annoyance if your ring fits perfectly otherwise. But, if swelling is causing your ring to be too uncomfortable to wear, it may be worth getting the help of an expert jeweler to size up your ring slightly.
