Tips & Tricks

Do

Measure your ring size at the end of the day when fingers are at their largest.

Consider the width of the band, a particularly thick band will feel tighter than a thin band so you may want to buy a full size larger than your normal ring size.

Ensure that your ring sizer fits comfortably, snug enough so that so that it will not fall off, but loose enough to slide over your knuckle.

Do Not

Do not measure your hands when they are cold, they may have shrunk up to half a size.

Alcohol and salt can make your fingers swell so refrain from measuring your ring size after any champagne and canapé filled evenings.
