📄 What Is a Ring Measuring PDF?
A Ring Measuring PDF is a printable ring-sizing guide designed to help you take basic ring measurements at home. It can include a paper measuring method, existing-ring comparison circles, diameter references and a UK ring size chart.
This page includes a printable A4 section that you can send directly to a printer or save as a PDF through your browser's print dialog. The key requirement is preserving the intended physical scale.
If a printable sizing guide is reduced or enlarged, the ring circles no longer represent their intended diameters. That is why the printable section contains a 50mm calibration line. Measure the line after printing and only use the chart if the line measures exactly 50mm.
For an important engagement ring, wedding ring or bespoke piece, use a Ring Measuring PDF as a practical starting point and confirm your final size with the retailer.

UK Ring Measuring Guide
Print at 100% / Actual Size. Check the 50mm calibration line before using the ring circles.
1. Verify the PDF Print Scale
Measure the line below with a physical ruler after printing. It must measure exactly 50 millimetres.
If the line is not exactly 50mm, change your print settings and print again.
Wrap a narrow non-stretch paper strip around your ring finger. Mark the overlap, flatten the strip and measure the length in millimetres.
Place a well-fitting ring over the printed circles below. Match the printed line to the inside edge of the ring opening.
The finished ring must pass over your knuckle while remaining secure at the base of the finger.
Take several measurements. Similar repeated results are more reliable than one quick reading.
Existing Ring Circle Matcher
The circles represent approximate inside diameters. Use the inside edge of your existing ring.
Finger Circumference or Existing Ring Diameter
Choose the method that matches the information or jewellery you already have.
Measure Finger Circumference
Use a narrow strip of paper around the exact finger and measure the marked length in millimetres.
Measure Existing Ring Diameter
Measure directly across the empty inside opening from inner edge to inner edge.
Use the PDF Circles
Print at 100% scale and place your ring over the circles to identify the closest match.
Confirm the Final Size
Check your result with another method or professional fitting for an important purchase.
Open the Print Window
Click the Print / Save Ring Measuring PDF button above. Your browser will open its standard printing interface.
Choose Print or Save as PDF
To create a digital copy, choose your browser or operating system's “Save as PDF” option. To use the sizing circles physically, choose your printer.
Select A4 Paper
Use A4 portrait paper for the printable sizing sheet where your printer settings provide that option.
Use 100% or Actual Size
Do not intentionally enlarge or reduce the printable sizing sheet. Look for settings such as 100% or Actual Size.
Avoid Fit to Page Scaling
Automatic fitting can change the physical measurements of the circles. If your print software scales the document, the chart may no longer be accurate.
Measure the 50mm Calibration Line
After printing, place a ruler against the calibration line. Only continue if the line measures exactly 50mm.
Match Your Ring or Measure Your Finger
Use either the printed diameter circles or the finger circumference method depending on which measurement is available.
If you do not have a suitable existing ring, you can use a narrow strip of paper to estimate finger circumference.
Wrap the paper around the base of the exact finger where the ring will be worn. Keep the strip snug without pulling it so tightly that it compresses your skin.
Mark the exact point where the end of the strip overlaps. Lay the paper flat and measure from its starting edge to the mark using a ruler with millimetre divisions.
That measurement represents your approximate finger circumference. Compare it with the UK table below or use our Ring Circumference Chart.
For detailed instructions, see Measure Ring Size with Paper.
If you already have a ring that fits the intended finger, it can provide a useful sizing reference.
Print the PDF section at the correct scale and verify the 50mm calibration line. Then place the ring directly over the printed sizing circles.
Look straight down from above and find the circle that aligns most closely with the inside edge of the ring. The printed line should sit close to the inner opening all the way around.
Do not match the outside edge of the jewellery. The thickness of the metal is not part of the inside diameter used for ring sizing.
| UK Size | Inside Diameter | Circumference | Diameter Inches |
|---|
Note: Ring charts are practical references and may use slightly different rounding between jewellers. Always compare an important purchase with the supplying retailer's size chart.
Verify the Calibration
Never trust the printed circles until the 50mm reference line has been checked with a real ruler.
Use Actual Size
Automatic page scaling can change every ring diameter printed in the PDF.
Use the Correct Ring
Choose a reference ring that fits the same finger and preferably the same hand as the intended new ring.
Match the Inner Edge
Size circles correspond with the inside opening, not the ring's outside diameter.
Check More Than Once
Compare several nearby circles and repeat the process before deciding on a letter size.
Confirm Important Rings
For a valuable or bespoke ring, use a physical jewellery sizing check as your final confirmation.
A printable diameter circle can help identify the internal size of a reference ring, but it cannot fully reproduce how a different-width finished ring will feel on the finger.
A wide wedding band covers more skin than a narrow ring and can therefore feel more snug even when the nominal UK size is the same.
For wide rings, use the PDF measurement as a starting point and try a physical sample with a similar width where possible.
Compare 2mm, 3mm, 4mm, 6mm and wider designs in our Ring Width Size Chart.
The terms Ring Measuring PDF and Printable Ring Size Chart are often used for very similar resources, but the emphasis can be slightly different.
A printable ring chart usually focuses on diameter circles for comparing an existing ring. A broader ring measuring PDF can also include paper finger measuring instructions, circumference conversions, size tables and calibration information.
This page combines both approaches so you can print one useful reference for home measurement.
You can also visit our dedicated Printable Ring Size Chart for a circle-matching guide.
Using Fit to Page
Page-fitting settings can shrink or enlarge physical reference circles.
Skipping Calibration
The PDF may look correct while still being physically scaled incorrectly. Always check the 50mm line.
Measuring Against a Screen
Phone and monitor scaling varies, so use a correctly printed copy rather than trusting on-screen physical dimensions.
Using the Outside Edge
Printed ring circles must match the inside opening of the reference ring.
Using Another Finger
A ring that fits one finger may not provide the correct size for another.
Relying on One Result
Compare with another method or professional fitting before an important purchase.
You can compare your home measurement with independent retailer guidance before choosing a final size.
Goldsmiths provides a UK ring measuring guide describing a finger measurement method using a narrow strip of paper and also recommends professional showroom sizing when the most accurate measurement is needed.

📄 Best Way to Use a Ring Measuring PDF
Save or print the A4 measuring guide, use 100% / Actual Size, confirm the 50mm calibration line with a physical ruler, measure the exact finger or match a ring that already fits, repeat your result and check the final size with the supplying jeweller before ordering valuable or bespoke jewellery.
