Printable and on-screen ring size guidance
Looking for a printable ring size chart that is easy to read and compare? This full ring sizing chart printable guide shows the inside diameter and circumference for US ring sizes, with conversions for UK, Europe, India, Japan, China, Australia, and other regional systems. Use the table when you already know a measurement in millimetres, or download the printable ring sizer chart to make a physical check at home. For an actual ring size chart on screen, keep your display at normal browser zoom and use the online ring sizer to calibrate the guide to your device. The result gives you a practical starting point before ordering a new, replacement, wedding, or engagement ring.
If you are comparing a mens ring size chart or mens ring measurement chart, start with the exact finger that will wear the ring rather than relying on an average. Measure an existing ring across its inside edge, or wrap a narrow paper strip around the finger and record the circumference in millimetres. Then match that number with the ring measurement chart US column and check the closest regional conversion. A wider band may feel tighter than a slim band, and fingers can change with temperature or time of day, so repeat any result that sits between sizes. For an important purchase, use this chart as a guide and confirm the final fit with the retailer or jeweller.
Searches for a woman ring size chart, female ring size chart, ladies ring size chart, or womens ring size chart all lead to the same practical need: a measured fit for the finger being sized. There is no universal women’s or men’s size that works for everyone, because left and right hands and individual fingers differ. Use the printable ring sizer chart only after checking your printer’s scale—choose 100% or actual size, not “fit to page”—then compare the printed guide with a ring or measured finger. If you prefer a no-printer option, use the on-screen sizer above, calibrate it with a card, coin, or ruler, and compare the result with this international chart.
Ring size chart FAQ
Answers about ring size charts and conversions
how to size a ring
Start with either the inside diameter of a ring that already fits or the circumference of the finger that will wear it. Match that measurement to the corresponding column, then read the US or regional size used by the retailer. For a wide band, treat the chart result as a starting point and check the seller’s fit guidance.
how do i measure the size of a ring
Measure across the inside of the ring, edge to edge, without including the metal band. Record the distance in millimetres and compare it with the chart’s inside-diameter column. Measuring the outside edge will make the ring appear larger than it really is.
how do you size your finger for rings
Wrap a narrow strip of paper or non-stretch thread around the intended finger, mark where it meets, and measure that length in millimetres. Compare the circumference with the chart, keeping the strip comfortable rather than tight. Repeat the check when your hands are at a normal temperature.
how to figure out my ring size
Use a measured ring diameter or finger circumference instead of estimating from an average. Find the nearest millimetre row, read the US size, and then check the regional columns if you are shopping from another country. A second measurement can help when the result sits between two rows.
how can you figure out your ring size
Take two careful readings of the same finger or well-fitting ring and write down the unit and measurement type. Use diameter for a ring measured across its inside and circumference for a finger measurement. Then choose the closest chart row and confirm the retailer’s available size increments.
how to measure ring size in cm
For a finger measurement, record the circumference in centimetres and multiply by 10 to convert it to millimetres. For example, 6.0 cm becomes 60 mm, which can be compared with the circumference rows. If you measured straight across a ring, use the diameter column instead.
how do you check ring size
Check a ring that fits by measuring its inside diameter, or measure the intended finger around its base with a paper strip. Match the result to this chart and read the size system required by the product listing. Do not rely on a ring from a different finger unless its fit is known.
how to measure a ring
Place a ruler across the inside opening and measure from one inner edge to the other in millimetres. Do not measure the outside diameter, and do not include the band thickness. Once you have the inside diameter, locate the closest row and compare the regional size columns.
how to measure my ring finger
Measure the exact finger that will wear the ring, because fingers on the same hand can differ. Wrap a slim paper strip around the base, mark the overlap, and measure the strip in millimetres. Take another reading later if the result is close to a size boundary.
what ring size am i
There is no reliable size based only on gender, height, or another ring finger. Your size comes from the inside diameter of a suitable ring or the circumference of the intended finger. Use that measurement with the chart, then check how the retailer names its sizes.
what is 2.5 inches in ring size
If 2.5 inches is the finger circumference, it equals 63.5 mm and is closest to approximately US 10½ in this chart. If 2.5 inches describes a diameter, use the diameter column instead, because diameter and circumference are different measurements.
are mens and womens ring sizes the same
The standard US ring-size scale is not split into separate male and female measurement systems. The same physical diameter and circumference can correspond to the same number for anyone. Labels such as men’s or women’s usually describe the product range, so measure the intended finger rather than choosing by category.
how to measure ring size in inches
First decide whether the value goes around the finger or across the inside of a ring. Convert inches to millimetres by multiplying by 25.4, then compare it with the matching circumference or diameter column. Mixing the two measurement types can produce a significantly wrong size.
what ring size is 6 cm
Six centimetres equals 60 mm around the finger. The closest rows here are about US 9 at 59.5 mm, US 9¼ at 60.2 mm, and US 9½ at 60.8 mm. Use your most precise measurement and check which quarter sizes the retailer offers.
what ring size is 7 cm
Seven centimetres equals 70 mm around the finger. In this chart, it falls between about US 13 at 69.7 mm and US 13¼ at 70.4 mm. Compare the exact circumference, consider the band width, and confirm the final size with the retailer when the fit is important.
Can I download a printable ring size chart from this page?
Yes. Select the printable chart download button above to save the PDF. Print it at 100% or “Actual size,” turn off “Fit to page” or similar scaling, and verify the chart’s calibration mark with a ruler before using it.
How do I print the ring size chart at actual size?
Open the PDF print dialog and choose 100% or “Actual size.” Disable automatic resizing, then measure the verification line or card outline after printing. If it does not match the stated length, change the print setting and print the chart again before measuring.
How many ring size rows are visible in the chart at once?
The table is sized to show 18 rows at a time. Scroll inside the table to reach the remaining sizes; its header stays visible as you move through the list, making the diameter, circumference, and regional columns easier to compare.
Which regional ring-size systems are included on this page?
The table includes US, Canada, and Mexico; UK, Ireland, Australia, South Africa, and New Zealand; Europe; China, Japan, South Korea, and South America; India; and Italy, Spain, the Netherlands, and Switzerland. Choose the column used by the seller.
Can I use the ring size chart on a phone or smaller screen?
Yes. On a narrow screen, scroll horizontally within the table to view every regional column while keeping the measurement rows readable. Leave browser zoom at its normal setting and use the chart’s own scroll area rather than zooming the entire page.
