HOW TO MEASURE YOUR RING SIZE

When it comes to how to measure ring size, the best way or the most accurate way to get a ring that fits properly is to visit a local jeweler’s shop. However, you can use a ring size chart, a plastic ring sizer, a printable ring guide, and other methods of measuring the ring size if you prefer to do the measuring at home.

METHOD 1

Request Primestyle Ring Sizer (Free)


PrimeStyle understands that you may not know the ring size for a particular finger. We are willing to send you a free plastic ring sizer so that you can easily measure your ring size at home.

Keep in mind, though, that the shipping and delivery time of these plastic ring sizers varies from place to place. If orders are within the US and Canada, it takes 5 to 7 business days, so it may take more time if the orders are from elsewhere.

Take note, too, that the ring sizing chart right below this section is meant for determining your ring sizes in the standard US and Canadian measurements. If you’re not from the US or Canada, use the international ring size conversion chart at the end of this page to get the correct ring sizes.

HOW TO MEASURE RING SIZE WITHOUT HER KNOWING

The beauty of a marriage proposal is best when it comes as a welcome surprise. Getting the right ring size makes a wedding proposal not only perfect but also challenging. Asking your partner directly for her ring size will definitely ruin a bit of the surprise element. Here are a few tips to get the right size.

ASK A CONFIDANT FOR HELP

This can be her best friend, her sister, or her mom. They can give you an idea of what her ring size is or help you to measure her ring size without her suspecting a thing. If you are using this method, you should only ask trustworthy people who may actually know. It is more likely that the news of your gift will reach her prematurely if you ask too many friends or those who are not good at keeping secrets.

BORROW FROM HER JEWELRY COLLECTION

CHANGING THE RING SIZE OR RESIZING

Diamond rings are gifts that are meant to last forever, but what if the finger it’s meant for shrinks or grows? People may undergo physical changes as they age, and you may find that you need to have your ring resized. Most simple rings can easily be resized by a jeweler. For rings that have diamonds set in the band, however, a ring resizing may be impossible. This is especially true if the ring has channel-set diamonds, which can become displaced by any kind of metalwork. If a ring does become too small or large and cannot be resized, you can also have a new band created for your current diamonds.

INTERNATIONAL RING SIZE CONVERSION CHART

Ring sizes vary from country to country. In the US, the sizes range from 0 to 20 and include quarter fractions, so for instance, you may have a ring size of 12 ¾ or 15 ½. Though you want to be as accurate as possible, people often get a size that is just a little larger, especially if the ring is going to be worn for a long time (as in the case of engagement rings or wedding rings). If you are planning to buy diamond rings online, take note that the ring sizes are generally shown in US sizes, unless the website is designed for selling diamond rings to a specific country. Don’t worry too much about that, though. We’ve got you covered with our international ring size conversion chart. Simply use the drop-down menu below, select your ring size from the available options, and the number will be automatically converted for you! It’s that simple. We’ve laid it all out for you, but you still have to read the ring sizing chart carefully to avoid mishaps. The last thing you want is getting inconvenienced all because you forgot to look at the detail that says which country’s measurement standard the ring sizes are based on.

HOW TO MEASURE RING SIZES IN INCHES WITHOUT SWEAT

In buying rings, the most difficult thing to do is how to figure out ring size. It is very crucial that we select the perfect fit in order to wear the ring comfortably. There are lots of methods to choose from. It would be great if you always have the plastic ring sizer with you, right? But not all the time this is available.
