1. Pin hair as flat and as tight as possible before taking the measurements.
2. Round your measurements up not down. Example: 12 3/4 should be rounded up to 13 and 12 1/4 should be rounded up to 12 1/2.
Note: If you are bald or do not have a hair line - you do not need to add the inch - simply put the tape measure where you would like your hairline to begin with the wig. The averages below are just examples. These measurements will not fit everyone-some may need bigger or smaller size.
