How to measure ring size at home
The most reliable home method is to measure a ring that already fits: match its inside diameter to a ring size chart. If no ring is available, wrap a thin strip of paper around the finger, mark where it meets, and match the length in millimetres to the same chart.

Take a ring the person wears on the same finger and measure its inside diameter in millimetres with a ruler, or place it over the circles of a printable ring size chart until the circle just fills the inside edge.
Use a ring from the correct hand: the ring finger of the dominant hand is usually about half a size larger.
Method 2: the paper-strip method
Cut a thin strip of paper, wrap it snugly around the base of the finger, and mark where the end meets. Measure the length in millimetres; that circumference converts directly to a ring size on a standard chart.
Measure at the end of the day when fingers are at their largest, and repeat twice to confirm. Do not pull the strip tight; the ring should slide over the knuckle.
Method 3: get measured professionally
Any jeweller can measure a finger in a minute with a metal sizing set, and it is the most accurate option. Fingers change with temperature, time of day and humidity, so a professional measurement removes the guesswork.
If the ring is a surprise, borrow one from the correct finger and have a jeweller size it on a ring mandrel instead.
What if the size is still wrong?
Most plain solitaire bands can be resized by a jeweller within one or two sizes. Rings with stones set all around the band usually cannot, so it is worth confirming size before ordering those styles.
