Being able to accurately measure clothing is critical to online selling. Without being able to try clothes on, the buyer is relying on you to provide as much detail as possible to assess whether clothes will fit. You should obviously include sizing details as well, but the measurements you take with your tape measure are likely to be much more useful.
These are the key measurements to take. Take only the measurements that make sense for the item you are selling. Use a proper tape measure. Don’t rely on stitching measurements together using a ruler or using measuring apps on your phone.
Waist: take your own measurement for this, regardless of any existing measurement on the label. Lie the item flat, measure across the waist, seam to seam, and double the number.
Inside leg: measure from crotch to leg opening along the inside seam
Outside leg: measure from top of waistband to leg opening along the outside seam
Leg opening: holding the opening flat, measure from inside seam to outside seam
Shirts, jackets, tops and dresses
Shoulder to hem: full length of garment front, from highest to lowest point, laid flat
Armpit to armpit: seam to seam across the front, laid flat
Sleeve: a proper sleeve measurement goes from neck to wrist, but it may be easier to measure the inside seam from the armpit to the wrist or from the shoulder to the wrist. Make it clear how you have made the measurement
Shoulder to shoulder: turn the garment on to its front and measure the full shoulder width across the back
Waist: for dresses take this measurement at the natural waist point, normally clear from the garment’s cut. If it isn’t clear, measure from around seven inches below the armpit
Neck drop: front and back neck drops are measured from the shoulder
