Is there a time of day that I should size my finger?
Size your finger later in the day. Our fingers change sizes throughout the day. They tend to be a little puffy in the morning and then shrink down later on. Fingers swell in warm weather and reduce in size when cold. They also tend to expand when you are engaging in physical activity. The most effective time to determine your ring size is at the end of the day when your fingers are at their standard size.
