Wedding Ring Size and Measuring Guidelines

Finding out your ring size may be a difficult task due to the fact that the UK doesn't have a standard set of units with which to measure finger size.

This issue can be absolved with the use of the ring sizer which upon request, we will send out to your home address. The ring sizer will then allow you to deduce your ring size easily

However, it is important to bear in mind that the style and width of the ring can play affect and alter your ring size slightly. Should you have any further queries or uncertainties regarding your ring size, just contact Elma jewellery and we will gladly dispense any advice and further information you may require.

Measuring Guidelines

Finger sizes do not correspond to body size. Your fingers will usually swell in the evening and shrink in the morning. Other factors that contribute to ring size include temperature, humidity and exercise. Wider bands can be bought looser as can be rings for someone with large knuckles while smaller knuckles need a firmer fit. The best size fits snugly but has a little resistance when you remove the ring.

Therefore follow these measuring tips in order to get the right fit:

  • Measure your ring size in the evening when your fingers are at their largest.
  • Do not measure when your fingers are very hot or cold as ring size fluctuates with temperature.
  • After finding your ring size make sure you can slide the ring sizer over your knuckles and off your finger.
