How To Make Sure the Engagement Ring Fits as It Should?

Buying a wedding band or engagement ring online is both easy and economical. But more importantly, it means you can calmly compare the many shapes, colours and types of diamonds without drawing attention from prying eyes. White gold or platinum? Round, oval or square? You have all the time in the world to turn the options over in your mind.

Whatever your taste, in BAUNAT's webshop, you'll find the perfect ring in no time at all. But how can you make sure that it will also fit like it should?

Read summary

How can you ensure the perfect fit when buying an engagement ring online?

While online ring shopping offers convenience and privacy for comparing diamond options, getting the right size is crucial. The European ring sizing system provides a straightforward measurement where the number represents the diameter in millimeters. For example, size 17 equals a 17mm diameter. The average woman's ring size falls between 16.5-17.4mm, while men typically measure around 20.5mm.

When uncertain about size, it's better to err on the larger side since resizing smaller is easier than expanding a ring. You can measure an existing ring that fits well, but remember that temperature affects ring size - fingers expand in heat and shrink in cold. For a surprise proposal, consider enlisting help from your partner's close friend to discreetly determine the correct size. BAUNAT offers expert guidance and customization options to ensure your chosen engagement ring fits perfectly.

Ways to Measure a Finger

You can use the European ring size as a guide, which is a common standard applied by jewellers and retailers. The system is childishly simple: size 17 simply means a diameter of 17 mm.
Measure one of their existing rings that fit well. But beware of temperature changes as heat makes a ring expand, and cold makes it shrink!

Are you having trouble getting a measurement for one reason or another? Then you'll have to take a gamble,or you could just follow the crowd. The average ring size of a woman's index finger is 16.5 to 17.4 mm. For men, it's around 20.5 mm.

How to measure at home (quick)

1) String or tape method: wrap a thin strip of paper, string or flexible tape around the base of the finger where the ring will sit. Mark where the ends meet and measure that length in millimetres. Example: if the measured circumference is 53.4 mm, divide by π (3.1416) to get the inside diameter: 53.4 ÷ 3.1416 ≈ 17.0 mm.

2) Measure an existing ring: lay the ring flat and measure the inside diameter across the centre in millimetres. Use that diameter to check the conversion chart above.

Practical tips: measure at the end of the day when fingers are slightly larger and avoid extreme temperatures. For wider bands, allow for a slightly larger fit - many people go up about half to one size for very wide rings to keep comfort.

Engagement Rings: Better Too Big Than Too Small

Making a ring smaller is a standard task, but making it bigger is a lot more complicated. If you're at all unsure of the width of your fiancée’s finger, it's better to go for the larger size than the smaller one. And if you're still stuck, try asking one of their best friends for help. They might be able to find out more easily and discreetly.

Resizing limitations and next steps

Not every ring can be resized easily. Rings with a continuous row of stones, full eternity settings or heavy channel-set designs are often difficult or impossible to make smaller or larger without affecting the setting. If the chosen style limits resizing, the usual options are an exchange for a different size or ordering a bespoke remake.

If a ring can be altered, smaller sizes are typically simpler to achieve than larger ones. When deciding between exchange and resize, prefer an exchange if the design has extensive side stones or delicate settings that resizing would compromise. Our team can advise on whether a specific design is suitable for resizing and outline the most practical next step for your purchase.
