Taking measurements
Before opening Blender, some measurements must be gathered. Careful measurements need to be taken of the ring finger and an SD card. A digital caliper is an excellent tool to take measurements with, as shown in the following figure:
My middle finger measures 19.3 mm at the widest point. If a digital caliper is not available, another way of measuring your finger is to wrap a piece of paper around the finger, mark where it overlaps, and use a ruler to find your finger's circumference, like this:
Then, consult the following table to find out the standard ring size and diameter:
