How to Measure Your Ring Size
Finding the perfect ring starts with the perfect fit. Learn with step-by-step instructions on how to accurately measure your ring size at home using simple tools.

Discovering your precise ring size is essential for both the comfort and the security of your fine jewelry. Whether you’re sizing for an engagement ring, a wedding ring, or simply expanding your everyday collection, knowing how to measure your ring size accurately ensures that each piece fits perfectly and feels right, especially if you're only ordering online.
This guide will delve into practical methods on how to measure ring size at home, using simple tools and techniques that you can master.
Tools to Prepare for Ring Sizing
To begin measuring your ring size at home, you'll need a few basic items:
- String or Floss - A small piece of non-stretchy string or dental floss can help you measure your finger circumference. Just make sure that it's thin enough to fit snugly without compressing your skin.
- Paper Strip - A narrow strip of paper may also be a preferred option because it is stiffer than string or floss, providing a straighter line for more accurate marking measuring.
- Ruler - A standard ruler with millimeter measurements ensures that you can convert your string or paper measurement accurately.
- Printable Ring Sizer - If you already have an existing ring, a printable ring sizer or ring size chart can provide a more straightforward approach to finding your size. You can download a printable ring sizer from many jewelry websites, including Jennifer Fisher. Ensure that you follow the instructions and that the printout is scaled correctly for accurate sizing.
Step-by-Step Measurement Guide
Method 1: Using String or Paper Strip
- Prepare Your Material - Cut a thin strip of paper or a piece of non-stretchy string. The paper strip should be 100 millimeters long and 5 millimeters wide.
- Wrap the Material - Carefully wrap it around the base of your ring finger or any finger of your choice. Ensure it's snug but not too tight, allowing the material to move comfortably over your knuckle so you get an accurate yet comfortable size.
- Mark the Spot - With a pen or marker, mark where the end meets the rest of the material, forming a complete circle.
- Measure the Length - Lay the material flat and use a ruler to measure the length in millimeters up to the marked point. This measurement is your finger's circumference.
Tips for Accuracy: To get an accurate measurement, wrap the string or paper around your finger three times and average the measurements. This method helps account for any slight variations during the wrapping process.
Method 2: Using an Existing Ring
- Select an Existing Ring - Choose a ring that accurately fits the finger you want to measure comfortably.
- Use a Printable Ring Size Chart - Place your ring on a size chart, which includes circles of different sizes. Match the inside edge of your ring to a circle on the chart to find your ring size.
- Verify the Fit - Double-Check that the sizing circle you chose fits snugly inside the ring without allowing too much space or tightness.

Understanding Ring Size
- Interpreting Ring Size Numbers - Ring sizes are usually listed as numbers, and these numbers refer to specific circumferences. For instance, a ring size 7 in the US typically refers to a finger circumference of about 54.4 millimeters.
- Consider the Knuckle Size - If your knuckle is significantly larger than the base of your finger, measure both the base of your finger and your knuckle, and select a size in between to make sure that the ring can slide on comfortably yet stay securely.
Tips for Accurate Measurement
Achieving the perfect fit requires attention to detail and an understanding of how other factors can also affect ring sizing. Here are some of those factors:
- Best Times to Measure Your Finger - Your finger size can change throughout the day due to activity, diet, and temperature. For the most accurate measurement, measure your finger at the end of the day when it is likely to be at its largest. Avoid measuring when you're cold, as fingers can be smaller.
- Handling Half Sizes - If your measurement falls between two sizes, choose the half size. A slightly looser ring is easier and more comfortable to remove than one that is too tight.
- Considerations for Wide Bands - Rings with wider bands tend to fit tighter. If you’re choosing a band that's wider than 6mm, consider getting a larger size (specifically one size up) from your normal ring size for a more comfortable fit.
Adjustments and Resizing
Even with careful measurement, you might find the need to adjust your ring’s size for a perfect fit as months or years pass, depending on your physical changes.
- When to do ring resizing - If your ring already feels uncomfortable, continuously slips off, or is too tight to remove easily, it's time to consider resizing. Most gold and sterling silver rings can be resized by a professional jeweler.
- Options for Temporary Adjustments - For slight adjustments or if resizing isn’t an option (like for some engagement rings or eternity bands), consider using ring size adjusters. These small tools can be inserted inside the band to make it fit more snugly without having to alter the ring permanently.
