Practical tips

There are a few basic guidelines to ensure an accurate measurement. Some environmental and physical factors that should be taken into consideration before deciding on the size of the ring you want to buy, but remember that when it comes to guessing your partner’s ring size, guess on the large side as it’s easier to size a ring down.


An ideal time to measure your finger size is in the evening.
Most people’s fingers are small in the morning and at their largest in the evening.
Measuring your partner’s finger size in the evening will guarantee the best fit.
Always make sure you measure the largest part of the finger.


Fingers can react to temperatures and change size depending on the weather.
The cold winter air will shrink fingers while the opposite happens in summer or when it’s warm and humid.
Always measure your ring size inside where you have a normal room temperature. Fingers expand and contract
Other factors can cause fingers to grow such as exercising, water retention, pregnancy, ageing, and arthritis.
Weight loss and low temperatures can cause fingers to decrease in size.


The average ring size range for a woman is between 49 and 54,
while sizes commonly range from 57 to 62 for men.
