Place the measuring tape around the neck at the height where the collar would normally rest. Stand relaxed. Do not crane your neck out or squeeze your chin down.
The tape should be resting lightly on the skin, not squeezing it.
Hold one finger under the tape measure to ensure some room for comfort.
This measurement will require a partner. If you don’t have a partner, measure a shirt directly.
Either way, it’s helpful to refer to a shirt that fits well in the shoulders.
Start the end of the tape on the outside edge of the shoulder where you want the yoke of the shirt to start.
This is where the horizontal part of the shoulder meets the vertical part of the arm.
Measure up over the curve of the shoulders and to outside edge of the other shoulder.
Run the measuring tape around the fullest part of your chest, tight up under your armpits and over the shoulder blades.
Let your arms hang down in a relaxed, natural pose.
Do not puff out your chest or arch your back in any sort of pose that isn’t natural or sustainable.
Place one end of the measuring tape at the base of the center of the back of the neck.
Run the measuring tape over your shoulder, and let it hang down to your hand.
Measure to the center of the meaty part of your palm.
Run the tape around the fullest part of the belly. This is usually around the level of the belly button. The measuring tape should be snug on the skin, but not squeezing in.
It’s important to stand in a relaxed, normal position–do not push out your belly or suck it in–when taking the waist measurement.
Measuring your waist for a dress shirt is different than the waistband of your trousers.
Measure the circumference of your hips. Start at one hip and wrap the tape measure around your rear, around the other hip, and back to where you started.
Make sure the tape is over the largest part of your buttocks. Because making sure the tape is level back there can be hard, try to do it in front of a mirror.
This is the distance from the uppermost inner part of your thigh to the bottom of your ankle. You can measure your inseam in two ways.
With help: While you’re wearing a pair of pants, have a friend stretch the tape from your crotch to the bottom of your ankle.
Without help: If you have a pair of pants that fit you perfectly (and they shouldn’t be too loose around the waist), measure the inseam of the pants, again from the crotch to the hem.
Measure the circumference of the fullest part of your thigh. Wrap the tape measure around your thigh from front to back and then around to the front.
You may be tempted to cheat by lowering the tape measure a few inches, but then you won’t get an accurate measurement.
Tip: Another person's assistance is helpful and will provide greater accuracy.
