Ring Size Guide

A ring should fit comfortably in the finger of the wearer as well as it should be tight enough which will prevent it from accidentally falling off. The best and most accurate way to measure a ring size is by visiting a local jeweller. Jewellers 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 measured by the distance across the middle inside. You can use below given ring size circles based on ring’s diameter for measuring your exact ring size. Please follow the steps to get the accurate ring size:

Select a ring that fits comfortably in the figure for which you are intended to know the size.

Take a printout of the below given figure A as per the given print instructions.

Place that ring over the circles to match with 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 Circumference

The circumference of a ring can be measured by its length around the inner circle. You can use below given finger size strip for measuring your exact ring size.

Please follow the steps to get the accurate ring size: Take a printout of the below given figure B as per the given print instructions.

Carefully cut this printout from the image outline to get a size strip. Also give a slit inside the strip at the left end.

Wrap this size strip around the intended finger 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. Also 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 the 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 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 ask your intended recipient’s mother or one of the friends if they know his / her finger size.

You can also borrow your intended recipient’s best fitted ring and find out the ring size by using above mentioned diameter method.
