How to Determine the Ring Finger Size of Your Partner

Avoid buying the wrong ring size for your partner!

Whether you are buying a diamond ring online together with your future partner or you are planning a secret proposal, you want to make sure you are getting the correct size for the ring to avoid disappointment and hassles of returns.

For many people (especially guys), finding out the correct ring finger size of the recipient can be a huge challenge and that is something I want to touch on today.

This write up will be split into 2 sections where I will reveal methods of determining ring finger size for people who don’t need to be discreet and for people who need to find out their partner’s ring size in secret.

Let’s get started with the 3 direct methods of finding out a ring size together with your partner.

#1. DIY Measurements With Your PC & Internet

If the option of using a jeweler to measure your partner’s ring finger size is not viable in your circumstances or you want to do it yourself, there are a number of ring sizer tools available at online jewelry websites.

For instance, you might want to check out this ring sizer widget that’s pretty easy to use.

Alternatively, you can print out pre-made templates and wrap it around your partner’s finger to get a size reading. Do take note that when you use this method, you need to ensure the print out is correctly scaled at 100 percent so that the sizer is not deformed.

#2. Head to the Jeweler to Measure Your Finger Professionally

The most ideal and accurate way to go about doing this is to have the finger measured by a jeweler or professional. With special tools and a set of graduated rings, they can help you determine the correct ring finger size in a couple of minutes.

#3. How to Determine Ring Size Using a String And Ruler

If you do not want to use a paper sizer nor want to visit a jeweler, you can use a ruler and a piece of string to perform the measurement of your partner’s finger. Simply tie a string around the ring finger and mark the point of connection on the string.

With this method, you want to make the string somewhat loose so that the ring is able to fit over the knuckle (the thickest part of the finger) smoothly.

Here’s an important point you need to be aware of: the hands should be warm in order to take accurate measurements. Ideally, the hands should be in an area with temperatures that are slightly higher than room temperature.

If the ring size was measured in colder temperature (the finger actually shrinks!), you might end up buying a ring that would be too tight and uncomfortable to wear.

How to Find Out Your Partner’s Finger Size Secretly

This section is catered for people who are planning a surprise for their partners and want to keep things under wraps. If your partner already wears rings, you can determine his/her ring finger size by ‘stealing’ one of their rings and taking it to a jeweler for measurement.

All you need to do is to find a way of getting the ring to the jeweler and returning it secretly without being found out. Obviously, the whole point of being discreet is to avoid alerting them so that you do not spoil the surprise.

However, if your partner doesn’t wear any rings, you’ll need to get creative.

Here are some methods I thought of:

• You could playfully compare the size of your fingers with your partner’s or play a guessing game and ask for proof by actual measurement.

• Ask your partner if they like wearing brass knuckles and use the chance to make paper brass knuckles for a specific costume or event. This can be a clear opportunity to measure your partner’s ring finger size using a string.

• Come up with a game that disguises a question about finger size that arouses her curiosity. For example, you could say that you read a trivial about Da Vinci’s golden ratio that states that the size of her palm divided by 3 would equal to the size of the ring finger. While there may not be scientific proof to back up this calculation, you could make use of this opportunity to measure her ring size.

Sometimes, it might be easier if you consult your partner’s friends or family for help or to do some brainstorming together. You could get in touch with one of her close friends and seek their assistance to help you out.

For example, you could ask them to bring her out for casual shopping and have them report their findings to you later. Heck, they could even be more direct and help you pop the question about her ring size with the excuse of being curious.
