You've decided it's time to pop the question so you set off to begin the search for that perfect ring! You visit your local jewellery store to browse their selection. You find a style you think your partner might like and the sales consultant asks "do you know her ring size?"
Having never been faced with this question before you stare at the consultant blankly. Multiple questions race through your brain, "Her finger size? Is that like her shoe size? How do I get her finger sized without her knowing?"
If this happens, don't worry! It is possible to purchase the ring and have it sized post engagenment. If you would prefer to give the ring in the correct size, then read along to discover some helpful tips for determining ring size.
#1: ASK A JEWELLER
This tip is the best way to ensure an accurate ring size. Most jewellers have a set of finger guages (ring sizers) that come in 1/2 size increments. A jeweller will slide the ring sizers onto your finger until one feels like a secure fit.

Since you may be trying to purchase a ring as a surprise, you can "borrow" an existing ring from his/her jewllery box. A jeweller will place the ring on a ring mandrel (sizing stick) to get an accurate measure of the exisiting ring. This will help in determining the size of a new ring.

#2: MULTISIZER RING SIZING GUAGE

This is an easy way to determine finger size at home. As mentioned in the photo above, the multisizer works like a belt. Simply adjust it to a comfortable fit and the number will correspond to your finger size. We keep a few of these multisizers on hand for clients to take home when needed. If you do not have access to a multisizer, they can be ordered through your local jeweller or online at Etsy or Amazon.
#3: ESTIMATE RING SIZE WITH A BAR OF SOAP
A sneaky way to get that ring size! Find a ring at home that she/he may already wear on their ring finger and press it onto a bar of soap. This will create an impression of the ring that you can bring in to your jeweller to have sized.
#4: OLD FASHION PAPER AND PENCIL
Trace the inside of an exisiting ring with a pencil. Bring this into your jeweller and they should be able to determine the size of the ring using the finger guages mentioned above.
#5: ASK A FRIEND/FAMILY MEMBER
Still no luck? Try asking a close friend or relative. Maybe she has dropped a few hints here and there and has left her correct ring size with a family member.

* It is important to note that the ring finger on the right hand can be slightly larger than the ring finger on the left hand. Finger sizes can also change slightly depending on the weather-fingers tend to shink in colder temperatures and swell in the heat. *
