Ring Size Guide: Find Your Perfect Ring Size at Home
Choosing the right ring size is one of the most important steps when buying a wedding ring. A properly fitted ring should feel comfortable, slide over your knuckle with slight resistance, and stay securely on your finger throughout the day.
At Risty Olivo, all of our rings are crafted using standard US ring sizes, making it easy to find your perfect fit whether you're ordering from the United States or internationally.
If you're unsure of your size, this guide will show you how to measure your ring at home in just a few minutes.
How to Measure Your Ring Size at Home
You only need a few household items:
- A thin strip of paper or a piece of string
- A pen or pencil
- A ruler with millimeter (mm) measurements
Step 1: Wrap the Paper Around Your Finger
Wrap the strip around the finger where you'll wear your ring. Make sure it comfortably passes over your knuckle without being too tight.
Step 2: Mark the Overlap
Use a pen to mark the point where the paper overlaps.
Step 3: Measure the Length
Lay the paper flat and measure the distance from the starting point to the mark in millimeters (mm).
Step 4: Compare With the Chart
Match your measurement with the ring size chart below to determine your correct US ring size.
Pro Tip: Measure your finger 2–3 times throughout the day. Fingers naturally expand in warm weather and shrink in colder temperatures.

Tips for Getting the Most Accurate Ring Size
- Measure your finger at the end of the day when it's at its largest.
- Avoid measuring immediately after exercise or exposure to cold temperatures.
- Your dominant hand is usually slightly larger than your non-dominant hand.
- If your measurement falls between two sizes, choose the larger size for a more comfortable fit.
- Wide bands (8mm and above) often feel tighter, so many customers prefer sizing up by half a size.
Still Unsure?
For the most accurate measurement, we always recommend visiting a local professional jeweler. Most jewelry stores offer complimentary ring sizing in just a few minutes.
Taking a few extra moments to confirm your size helps ensure your custom ring fits perfectly from the day it arrives.
Frequently Asked Questions
What if I'm between two ring sizes?
If you're between sizes, we generally recommend choosing the larger size, especially for wider wedding bands.
Do wide rings fit differently?
Yes. Wider bands cover more of your finger, making them feel tighter than narrow rings. Consider going up half a size for 8mm or wider bands.
Does finger size change?
Yes. Temperature, hydration, activity level, and time of day can all affect finger size. Measure several times for the most reliable result.
Can I measure with an existing ring?
Absolutely. Measure the inside diameter of a ring that already fits comfortably and compare it with the conversion chart.
Which sizing system does Risty Olivo use?
All Risty Olivo wedding rings are manufactured using US standard ring sizes.
