Adult measuring guide
Use the tips & visuals in this guide to take body measurements accurately & easily.
Don't have a fabric tape measure? Use a shoelace or pant leg to measure. Then, lay it flat & use a ruler or tape measure to get a numerical measurement.
How to measure
- 
                
Chest
With arms at your sides, measure around the fullest part of your chest & shoulder blades, keeping the tape level & snug.
 - 
                
Waist
Bend slightly to one side. The crease is where your natural waistline is. Measure a comfortable loose, level line around that point.
 - 
                
Inseam
Take a pair of pants that fit well. Now measure along the seam from the crotch to the leg opening.
