Important: Tiara uses U.S. sizes for our rings.
Your U.S. ring size is approx. SG size divided by 2. For example, SG16 = US8.

You can measure your ring yourself by getting a ring sizer
You can request a ring sizer from www.Tiara.com.sg at most of the ring's product pages where you can also see the image of the ring, so once again you don't need to leave home to complete this ring measuring process.
In general, a plastic ring sizer belt tape with a wide gradient of rings sizes is one of the best ring sizers you can find for measuring women's and men's fingers.
TIARA.com.sg has a high-quality measuring belt tape with a pointy slider plastic arrow that you can use to measure accurately your ring size. The sizer can measure ring sizes for both women and men ranging in US ring size from 1 to 17. As well as full sizes, it can measure half sizes and even slightly off sizes to select the right ring sizing once you wrap it around your finger.
The most common ring sizes for men and women
Adults generally wear rings ranging in sizes from US ring size 4 to 14. For example, the size of the average women's ring size ranges from US ring size 4 to 10 whereas that of the average man's ring size typically falls between US ring size 7 to 14. This is true for Singaporeans as well.
Three most common Women's ring sizes
Common ring sizes for women are US ring sizes: 5 (15.7 mm), 6 (16.51 mm) and 7 (17.35 mm).
Three most common Men's ring sizes
Common ring sizes for men are US ring sizes: 9 (18.89 mm), 10 (19.84 mm) and 11 (20.68 mm).
How to know if your ring size is correct?
The ring should be able to fit comfortably on your finger: snug enough not to slip off but still slightly loose enough so you can slide over the knuckle without being too tight. A good sign of a perfect fit is if your ring slides on comfortably over the knuckles with a little room to spare. You don't want it too tight, but you also don't want any sliding around; this may scratch or damage other surfaces in close proximity.
In order to assess your ring sizes accurately, you should know a few important points:
Take a moment to consider your knuckle. If you have large knuckles, we recommend ordering 1/2 size larger than the ring size indicated just by your finger measurement. Otherwise, you won't be able to slide the ring on. Take note too if you are getting men's gifts as there are some sports which might widen the knuckles.
It would help if you tried multiple times to ensure accuracy. It has been recommended by several individuals that you measure your finger 3 to 5 times. This is because the finger size varies with the temperature: if you're cold, your finger will probably be smaller; if you're hot, your finger will probably be larger. This will help you search for the right size.
If you follow these three methods, knowing what size a ring is should be easy and help you get a suitable piece of jewellery, whether it be a gift for yourself, your love or a wedding ring.
Option 2: Printable DIY Ring Size Measuring Kit

1) All our sizes are indicated on the product page under 'Ring Size' selection.
2) Please note that some designs do not come in half size. Therefore, you will have to choose the closest size available for the design.
1) Ring Size Wrap Method: Cutout and measure
Please make sure that you use a ruler to measure the bar on the top right of the printed paper. It should measure 3cm exactly. If it's not, the sizing will not be accurate.
Carefully cut the ring sizer out and use it like the ring sizer above in option 1. You will need to be very careful in making sure the cutout is accurate, especially the pointed end and also for the slit of the hole to not be too wide.
As it is made of paper, printing on a thicker piece of paper will be ideal.
2) Matching Method: Placing an existing ring on the ring size chart
If you already own a ring that fits well, you can use this measurement. Print off a proper ring size chart like this one from Tiara.com.sg above and then placing your ring on each circle till you find one that corresponds with your ring's inside circumference.
Important: The inside circumference of the ring should not fully cover the entire circle. The correct ring size match is the last ring size circle which you can still see the edges of the printed circle without being fully covered.
Example of an incorrect measurement: Ring size 9 will fully cover the printed US size 10, this is incorrect. Ring size 9 will fully cover printed US size 11 also because it has overshot the sizing.
Correct measurement: When the physical ring size 9 is placed on top of the printed US size 9, you will still be able to see the edge of the printed ring size around the ring.
When measuring the ring size, pick the one that covers almost the entire inner edges of the ring. It is important to note that using a larger circle will hide the inside edges of your ring as well, so try out different circles and make sure your eyes are directly on top of the chart (not sideways) to be sure your ring size is accurate. You can use a pen to tip on the edges too to trace it out.
Option 3: Common Ring Size Reference Chart Measurement And Ring Size Conversion Guide
Measuring your finger with string, paper or dental floss
Strings can be used to measure ring sizes, or you can use dental floss, which is a common household item. Mark the spot where you can see the string or dental floss overlaps and mark it with a pen when you wrap 1 of these measurement device round the base of the finger. Using the ruler, pen and paper, measure its length in millimetres and mark it on the piece of paper and ruler with a sharp pen. Look at the markings on the paper to measure the length or circumference. Try this a few times using the string and straighten it out with the ruler before measuring and then look at our ring size chart or ring size guide to have the conversion.
Rule of thumb: 0.4mm inner diameter increase is half size up
The standard ring size is by 0.4mm increments, so size 4 equals 14.86 millimetres, size 4.5 equals 15.27 millimetres, size5 equals 15.7 millimetres, etc.
Three most common Women's ring sizes
3 of the most common ring sizes for Women are US size: 5 (15.7 mm), 6 (16.51 mm) and 7 (17.35 mm).
Three most common Men's ring sizes
The three most common ring sizes for men are: 9 (18.89 mm), 10 (19.84 mm) and also 11 (20.68 mm).
International and Singapore Ring Size Chart
You will find in this ring sizing chart the millimetres your ring is and the ring size this translates to within the ring size chart.
Think of the string and dental floss as your measuring equipment. You don't want to put too much strain on them because if so, they'll stretch out, making for inaccurate measurements! If this happens, any rings that you may purchase in the future might be too large or not fit at all - so it's essential to take care when using these materials.
The ring size that corresponds to your finger's width in millimetres is an easy way of choosing the perfect engagement ring or wedding band for you. Ring sizes correspond to your finger's width in millimetres: Ring size 6 will fit your finger with an inside diameter of 16.51 millimetres, and so on.
If a woman typically wears rings with sizes between 5-7, then they will need one around this range as well. Make sure to have a good measurement because sometimes people end up getting something smaller than what was initially planned on just so their partner isn't disappointed or feel guilty about spending more to get another ring.
How to measure ring size in cm?
Some customers ask how to measure ring size in cm, you simply need to divide the millimeter by 10 for the ring size chart conversion. So 4 millimeters is 0.4 cm and vice versa, 0,5 centimeters is equal to 5 millimeters. This is how to measure ring size in cm.
US ring sizes and Ring Size Chart Conversion
Ring sizes in the United States are assigned in a range of numbers which sometimes includes half numbers. Most designs are usually in full sizes. At www.Tiara.com.sg, we use US ring sizes and you can refer to our ring size guide and printable ring chart to measure ring size for the perfect fit.

If your measured ring size is in between sizes, round to the closest more comfortable size. (eg. US 7.75 >= 8 ). It is more common to round up than down.
