Ring Sizing Myths Debunked: How to Buy an Engagement Ring in Singapore
Shopping for a proposal ring is exciting, but the sizing part trips up almost everyone. Some people borrow their partner’s ring off their finger for an afternoon without them noticing. Others just eyeball it based on how big their partner’s hands look. Neither approach is as reliable as it seems, and a bad guess usually means a ring that spins around the finger or won’t come off over the knuckle.
The good news is that most sizing mistakes come down to a handful of persistent myths. Once you know what’s actually true, buying with confidence gets a lot easier, especially if you’re working with a jeweller who offers proper sizing support, like Michael Trio’s complimentary sizers and in-store fitting help.
The Myths People Keep Repeating
- I have one ring size, period
Not quite. The circumference of your ring finger is usually different from your index or middle finger, and even your left and right hands can measure differently. Whatever finger the ring is actually going on is the one that needs measuring not a finger you happened to size once years ago.
- I can guess my partner’s size
Height, build, or general hand size don’t translate reliably into a ring measurement. If you want to keep the proposal a surprise, a better move is to quietly take one of your partner’s existing rings one worn on the correct finger to a jeweller and have that measured instead.

- My size is fixed forever
Fingers swell and shrink with heat, cold, activity, even time of day. That’s why a single measurement taken once isn’t as trustworthy as checking a couple of times under different conditions.
- Tighter means more secure
There’s a difference between snug and painful. A diamond ring should resist sliding off easily but still glide over the knuckle without a fight and let you move your hand normally. If it’s leaving a mark or cutting off circulation, it’s the wrong size, not the “safe” size.
- Width doesn’t change anything
It does. A wide band in the same nominal size as a thin one will almost always feel tighter, because more metal is in contact with the finger. If you’re eyeing a chunky statement ring or a wide wedding band, it’s worth getting fitted specifically for that style rather than assuming your usual size will carry over.
Measuring It Properly
A ring sizer is the simplest tool for this, and it’s worth using one rather than guessing from a printable chart. Michael Trio provides these free to customers who want to check at home before committing to a purchase.
The process is straightforward: slide the sizer onto the finger you’ll actually be measuring, tighten it until it feels snug but not restrictive, and check that it still clears the knuckle without force. Note the size, then repeat the check on a different day to make sure the reading holds. If you land between two sizes, Michael Trio’s guidance is to round up rather than down.

If your partner already owns a ring that fits well, that works to measure its inner diameter against a standard sizing chart. It’s a decent shortcut, but nothing beats having a professional confirm it in person.
Fit Is Only One Piece of the Decision
Once size is sorted, the rest of the decision comes down to the ring itself the setting, the metal, the diamond shape, and how it’ll actually hold up to daily wear. A slim solitaire wears very differently from a wide pavé band, and someone who’s active or works with their hands often does better with a lower-profile setting than an elaborate one.
Michael Trio’s Singapore range covers solitaire, halo, pavé, vintage, three-stone, curve, and twisted designs, with a custom ring builder for couples who want more say in the details stone shape, setting style, metal, band width, engraving, and so on.
If the Size Turns Out Wrong
Surprises don’t leave much room for a fitting session beforehand, so it’s fairly common to be slightly off on the first try. Before buying, it’s worth checking what the resizing policy actually covers. Michael Trio offers free resizing for a specific time period for purchases made in Singapore, which takes the pressure off getting it exactly right the first time.
If a ring does come back too loose or too tight, take it back to the jeweller rather than trying to adjust it at home resizing is a job for someone with the right tools, not a DIY project.
The Short Version
Choosing the perfect ring size doesn’t have to involve guesswork. By understanding common sizing myths, measuring the correct finger and seeking professional assistance, you can significantly improve the chances of getting a comfortable fit.
Whether you’re planning a surprise proposal or shopping together as a couple, take the time to confirm the measurement before placing your order. Once the sizing is sorted, you can focus on what really makes the ring special: the diamond, design and story behind it.
