Ring Size Guide

An ideal time to measure your finger size is in the evening. Most people’s fingers tend to be at their largest in the evening and smaller in the morning. Measuring your finger size in the evening will guarantee a comfortable fit. 

Fingers tend to react to temperatures, and can 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. Avoid measuring finger size outside in the very cold or very hot. 

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. 

Thicker ring bands (larger than 6mm) will fit tighter. It is advised to always go for half a size up when purchasing a thicker band, for the ring to be comfortable.
