The clothing industry must follow basic POMs (points of measure) when specing different garments, shoes, and fashion accessories. Measurements can be taken "on the half", or total depending on the particular companies requirements.

Here are a few examples of how you can take measurements.
Inseam: measure the inseam by starting at the center crotch seam, then measuring all the way down one leg to the hem. Be sure that the tape measure lays flat against the jeans to get an accurate measurement.
Front Rise: take the front rise measurement of the pants by measuring from the center crotch seam up to the top of the waistband.
Rear rise: flip the pants over so that the front of the pant is laying flat on the table. Measure from the center crotch seam to the top of the waistband on the backside.
Waist: measure the waits of the pants by stretching the measuring tape horizontally across the waistband while the pants are laying flat. After measuring, multiply the number by two to determine the full waist circumference (note: some size specs will indicate if the factory should use the half or full circumference measurement).
How to measure and points of measure go hand in hand. When producing garments it is important to understand full details regarding both the points of measure and the method in which to take the measurement.
