2. Ring Sizer Printable
The printable ring sizer provides two accurate and user-friendly methods to help you find your correct ring size from home. Both methods require printing the tool at 100% scale to ensure precise measurements.
In Method 1, you print and cut out a paper strip, insert the pointed end through the slit, and wrap it around your finger. Once it fits snugly but comfortably, you read the size indicated by the arrow. This method works like a measuring tape and is ideal for sizing your own finger.
Method 2 involves printing a chart of ring size circles. You take a ring that fits well and place it over the printed circles to find the one that aligns exactly with the ring’s inner edge. This method is perfect for determining someone else’s ring size based on an existing ring. Both options are reliable, simple to use, and great for those who prefer a physical sizing guide over digital tools.
Method 1: Using the Paper Strip
- Print the ring sizer sheet at 100% scale (do not resize or scale to fit page).
- Cut along the dotted line where it says “Find your size” to create a small slit.
- Insert the pointed end of the strip through the slit to form a loop.
- Slide the strip onto your finger and pull gently until it fits snugly but comfortably.
- Read the number where the arrow points—this is your ring size.
- Avoid pulling the strip too tight; it should feel secure but not restrictive.
- For best results, ask someone to help you with the measurement.
- Double-check your result to ensure accuracy.
Method 2: Using the Ring Size Chart
- Print the chart with ring size circles at 100% scale (actual size).
- Take a ring that already fits the intended finger well.
- Make sure the ring is worn on the same finger you are shopping for.
- Place the ring over the printed circles on the chart.
- Match it to the circle that aligns exactly with the inside edge of the ring.
- The correct size will touch the ring’s inner edge perfectly without overlapping.
- Confirm your result by checking again to be sure it’s accurate.
3. Ring Size Chart
This ring size chart is a convenient tool to help you find your correct ring size using an existing ring. You have two easy options to use it: either print the chart at 100% scale or view it on-screen at 100% zoom. For the printed version, simply place your ring over the circles and match it to the one that aligns perfectly with the ring’s inner edge. For the digital method, make sure your screen is set to 100% zoom (actual size), then place your ring directly on the screen and adjust as needed. Each circle is labeled with a size number and its corresponding inner diameter in millimeters, ranging from size 3 (14.0MM) to size 13.5 (22.6MM). This makes it easy to find a precise fit without any special tools.
Steps to Use the Ring Size Chart
Option 1: Printed Chart
- Print the chart at 100% scale (no resizing).
- Use a ring that fits well on the intended finger.
- Place the ring over the printed circles.
- Find the circle that matches the inner edge of the ring exactly.
- The number inside the circle is your ring size.
- Double-check for accuracy with nearby sizes if needed.
Option 2: On-Screen Chart
- Open the chart on your screen and set zoom to 100% or “actual size.”
- Use a ruler to confirm the scale if needed.
- Place your ring directly on the screen.
- Match it to the circle that fits the inner diameter perfectly.
- Note the size shown in the circle.
- Recheck to confirm your measurement.
4. Measure Your Ring Size with String
Measuring your ring size with a piece of string is a quick and simple method you can do at home with minimal tools. All you need is a small piece of string, a ruler, and something to mark with. This method involves wrapping the string around the base of your finger, marking where it overlaps, and then measuring the length to determine your ring size. It’s a convenient option if you don’t have a ring to reference and want to get an estimate before ordering. Just be sure to follow the steps carefully for the most accurate results.
Steps to Measure Your Ring Size with String
- Step 1: Cut a piece of string (or use dental floss) about 4–6 inches long.
- Step 2: Wrap the string around the base of the finger you want to size.
- Step 3: Make sure the string fits snugly but comfortably—not too tight or too loose.
- Step 4: Use a pen or marker to mark the point where the string overlaps.
- Step 5: Lay the string flat and measure the length from the end to the mark using a ruler (in millimeters).
- Step 6: Use a ring size conversion chart to match your measurement to the closest ring size.
- Step 7: Repeat the process once or twice to confirm accuracy.
Measure Ring Size with a Tape Measure
Using a tape measure is one of the most accurate and straightforward ways to determine your ring size at home. A flexible measuring tape, like the kind used in sewing, wraps around your finger comfortably and gives a precise measurement of its circumference. This method is especially helpful if you want a reliable result without printing charts or using other tools. With just a few simple steps, you can find your ring size and ensure a perfect fit before making a purchase.
Steps to Measure Ring Size with a Tape Measure
- Step 1: Use a soft, flexible measuring tape—ideally the kind used for sewing or tailoring.
- Step 2: Wrap the tape measure around the base of the finger you want to size. Make sure it’s the exact finger and hand where the ring will be worn, as sizes can vary between hands.
- Step 3: Adjust the tape so it sits snugly around your finger without squeezing it too tightly. It should feel secure but comfortable.
- Step 4: Note the point in millimeters (MM) where the end of the tape meets the remaining length. This is your finger’s circumference.
- Step 5: Use a ring size conversion chart to match your measurement to the corresponding ring size (US, UK, or EU).
- Step 6: For best results, measure your finger at the end of the day when it’s naturally a bit larger and avoid doing it when your hands are cold.
- Step 7: Repeat the process once or twice to ensure your measurement is consistent.
