Ring Size Guide

A ring should fit comfortably on the finger of the wearer as well as be snug enough to prevent it from accidentally falling off. The best and most accurate way to measure a ring size is by visiting a local jeweler. Jewelers use a set of graduated rings and other specialized tools to determine ring size. Ring size can also be measured easily at home by any of the following ways:

Ring Size Measurement by Ring’s Diameter

The diameter of a ring can be determined by measuring the distance across the middle inside. You can use the ring size circles below (based on ring’s diameter) for measuring your exact ring size. Please follow the steps listed below to get an accurate ring size:

Select a ring that fits comfortably on the finger for which you want to know the size.
Take a printout of the visual ring chart below as per the print instructions below.
Place your ring over the circles to match up with the nearest circle size to find the inside size of the ring.
If the ring falls in between two sizes, then it is advisable to go for the larger size.

Ring Size Measurement by Ring's Diameter

Ring Size Measurement by Ring’s Circumference

The circumference of a ring is measured by the length around the inner circle. You can use the finger size strip below for measuring your exact ring size. Please follow the steps to get the accurate ring size:

Take a printout of the below as per the given print instructions.
Carefully cut this printout from the image outline to get a size strip. Also cut a slit inside the strip at the left end.
Wrap this size strip around the finger you wish to measure with the scale facing out and then slide the narrow end of the strip through the slit.
Pull the narrow end until the fit is snug. Try to move that fit through the largest part of the finger; this may be the knuckle.
The number that lines up at the slit represents the ring size for that finger.

Print Instructions

To get accurate ring size results, please follow these print instructions:

You must make sure that you do not have ‘Shrink oversized pages to fit paper size’ or ‘Expand small pages to paper size’ selected in the Print Dialog Box.
You must also make sure that you have taken printouts without changing the image size either intentionally or unintentionally.
You can verify the sizes of the image printouts by measuring them with a ruler.

Tips for Measuring Accurate Ring Size

You should avoid measuring cold fingers as this is when fingers are at their smallest size.
You should measure your finger in warm temperatures at the end of the day.
If your ring size falls in between two ring sizes then it is advisable to go for the larger size.

Tips if you’re buying the Ring as a Surprise

You should try to find out from a reliable source; friend, parent, etc. what the intended recipient’s ring/finger size is.
You can also borrow your intended recipient’s best fitted ring and find out the ring size by using above mentioned diameter method.

Other Tips and Information

Facts about International Ring Sizing

In the United States and Canada, ring sizes are specified using a numerical scale, with quarter and half sizes.
In the United Kingdom, Ireland and Australia, ring sizes are specified using an alphabetical scale, with half sizes.
In Japan, ring sizes are specified using a numerical scale, with only whole sizes.
In Switzerland, ring sizes are specified using a numerical scale, with quarter and half sizes.
In Europe (excluding Ireland and the UK), ring sizes are specified using a numerical scale, with half sizes.

Resizing your Ring

Most gold or silver rings can be resized by a skilled jeweler by way of soldering or stretching and compressing. However, some rings cannot be resized due to gemstone setting, plating, shape or surface design. Usually small resizing does not create problems, but more extreme resizing can noticeably impact the look and structure of your ring. Increasing the size of a ring typically requires gentle hammering and this will cause the shank of the ring to thin slightly. For decreasing or increasing the ring size, your jeweler may also remove or insert extra metal through soldering. Some jewelers do not resize platinum because of its density and strength.

Necklace Length Guide

Necklaces and chains are available in different lengths and styles. You should choose the length and style of the necklace or chain based on neck size, personality and clothing.

Neck Size Measurement

Neck size can be measured easily by using a sewing (soft) measuring tape. Wrap this tape around the base of your neck to determine neck size. If you don't have a soft measuring tape, then you can also use a yardstick, ruler or stiff metal measuring tape. In this case, you need to wrap a ribbon around the base of your neck, mark the spot where it meets, and then lay it against the yardstick or metal measuring tape to determine neck size.

Types of Necklaces Based on Length

Necklaces traditionally come in six lengths. Depending on the length, the necklace will hang to a different part of the wearer's body.

Collar Length: 12 to 13 Inches
Collar necklaces are worn closely around the neck and can consist of multiple strands. This type of necklace looks nice with V-necks, boat necks and off–the–shoulder clothing.
Choker Length: 14 to 16 Inches
A Choker has a very classic as well as a versatile look and falls around the base of the neck. Chokers look beautiful on all types of clothing or neckline.
Princess Length: 17 to 19 Inches
The Princess is the most popular necklace length and falls just below the throat. It lies between choker and matinee length. A pendant can also be added for a bold and eye-catching look. Princess necklaces look beautiful on all types of attire.
Matinee Length: 20 to 24 Inches
Matinee style also offers one of the most popular necklace lengths and it comes in between princess and opera length. Matinee necklaces look stunning on casual or business attire.
Opera Length: 30 to 36 Inches
Opera necklaces come in lengths which range from 30 to 36 inches long. You can wear this as a single or double strand. It is perfect for high or crew necklines and is very complimentary, especially to evening wear.
Rope Length: 40 to 45+ Inches
A Rope necklace comes in the longest length and it has a different and dramatic look. A rope necklace looks elegant on most any type of clothing. This necklace can be transformed into multi-strand necklace and when worn with strands of graduated lengths, it is known as a bib necklace.
