For example, the wire part that goes through the ear will likely be 18-gauge (which measures as 1mm or 0.04-inch) or 20-gauge (which measures as 0.80mm or 0.032-inch).
The ring part of the leverback can be measured with the caliper from the outside and the inside to determine what width of wire or headpin can be inserted into the ring opening.
