Introduction:
Choosing the right ring size is essential for comfort and ensuring your cherished jewellery stays secure. Whether you’re selecting a sparkling engagement ring, a meaningful wedding band, or a stylish fashion ring, getting the correct sizing is paramount. At Adorne, we understand the importance of a perfect fit. That’s why we’ve created this comprehensive guide outlining three simple yet effective methods to accurately measure your ring size from the comfort of your home. Say goodbye to guesswork and hello to the flawlessly fitting ring of your dreams!
Method 1: The Paper Strip or String Method
This is a classic and readily accessible method to get an approximate ring size.
How it Works:
- Gather Your Supplies: You’ll need a thin strip of paper (approximately 5-6 inches long and ¼ inch wide) or a piece of non-stretchy string, a pen or fine-tip marker, and a ruler with millimetre (mm) markings.
- Wrap and Mark: Gently wrap the paper strip or string around the base of the finger you wish to measure. Ensure it’s snug but not too tight; it should be able to slide over your knuckle.
- Mark the Overlap: Use your pen or marker to indicate the exact point where the end of the paper or string overlaps.
- Measure the Length: Lay the paper strip or string flat and use your ruler to measure the distance from the starting end to the mark you made. Record this measurement in millimetres (mm).
- Consult a Ring Sizing Chart: Compare your measurement to a detailed ring sizing chart (see example chart below). This chart will help you determine your corresponding ring size.

Important Considerations for Accuracy:
- Time of Day: Measure your finger at the end of the day when it’s likely to be its largest.
- Temperature: Avoid measuring when your hands are very cold, as this can cause your fingers to shrink.
- Knuckle Size: If your knuckle is significantly larger than the base of your finger, take two measurements (around the base and over the knuckle) and choose a size in between or consult a jeweller.
- Multiple Measurements: It’s always a good idea to measure the same finger a couple of times to ensure accuracy.
Method 2: Measuring with an Existing Ring
If you already own a ring that comfortably fits the finger you want to size, you can use it as a reference.
How it Works:
- Select the Right Ring: Choose a ring that fits the intended finger perfectly.
- Measure the Inner Diameter: Place the ring on a ruler and carefully measure the inside diameter (the straight line across the inside of the ring from one edge to the other at its widest point) in millimetres (mm).
- Refer to a Ring Sizing Chart: Use the inner diameter measurement to find your corresponding ring size on a ring sizing chart (see example chart below).

Tips for Using an Existing Ring:
- Ensure the ring you’re using fits the correct finger comfortably.
- Measure the inner diameter at its widest points for the most accurate reading.
Method 3: Using a Professional Ring Sizer
For the most accurate ring size measurement, especially for important purchases like engagement rings or wedding bands, using a professional ring sizer is highly recommended.
How it Works:
- Order a Ring Sizer: You can often purchase a plastic or metal ring sizer online from jewellery suppliers or sometimes receive one for free from jewellers.
- Use the Sizer: Slip the ring sizer onto your finger like a regular ring. Adjust the loop until it fits comfortably – snug enough that it won’t easily slip off, but loose enough to slide over your knuckle.
- Read Your Size: The ring sizer will have clear markings indicating the ring size.
Benefits of Using a Professional Ring Sizer:
- Accuracy: Provides the most precise measurement.
- Convenience: Easy to use and reusable.
- Consideration for Band Width: Some professional sizers account for the width of the ring band, which can affect the fit.
Finding the perfect ring size doesn’t have to be a daunting task. By utilizing one of these three methods, you can confidently determine your ideal ring sizing. Remember to consider factors like the time of day and temperature for the most accurate results.
