USA industry standards use the metric chart for doll eyes. Eyes are almost always sized in mm (Millimeters). We always suggest you use the recommended size that the doll sculptor/artist/reborn artist's suggest. Note that 1/2 round glass eyes and 1/2 round oval eyes run larger than acrylic doll eyes.
1. CLICK HERE for example to measure the size of a doll eye, use a soft measuring tape and measure the diameter (from side to side. not the diameter) of the eye.
2. CLICK HERE for example to measure for what size of doll eye you will need, measure the inside edge of doll head eye hole to the outside edge. Do not just measure the empty space as this will give a too small of size reading.
3. CLICK HERE - To measure the Iris of a doll's eye, measure the diameter (side to side) of the colored part of the eye. CLICK HERE for example.
4. To measure the pupil of a doll's eye, measure the diameter (side to side) of the black center of the eye the same ways as for the Iris.
