Finger gauges and ring mandrels answer different questions. Choose the tool for the object being measured.
Measure a finger
A finger gauge is used to assess finger size. Check its sizing system and instructions, then compare the result with the ring seller's sizing chart.
Measure an existing ring
A marked ring mandrel helps check an existing ring. The markings and measurement range need to match your requirements. Unmarked forming mandrels serve a different purpose.
Compare a kit
A measuring kit may combine gauges, a mandrel and adjustment accessories. Read the included-items list; size adjusters change the fit of suitable rings and do not replace measurement.
Before you order
- Confirm the scale: US, UK, EU, HK or another stated system.
- Confirm the item being measured and the range required.
- Check whether the listing is for one tool or a set.
