How to measure yourself for shirts and T-shirts

Accurate measurements are the foundation of a well-fitting shirt or T-shirt. Here’s how to measure yourself step-by-step:

Chest

Wrap the tape measure around the fullest part of your chest.  Keep the tape parallel to the ground and make sure it's snug but not tight.

Shoulders

Measure straight across the back at the widest point, usually where your shoulders naturally slope. 

Neck (for dress shirts)

Wrap the tape measure around the base of your neck, just below the Adam’s apple. Allow space for comfort by placing one finger between your neck and the tape.

Sleeve length

Measure from the top of the shoulder where the seam would sit and run the tape down the outside of your arm to the wrist bone. 

Shirt length

Measure from the highest point of your shoulder (near the base of your neck); then it’s  a case of your preferred shirt length. For casual shirts, it might end around the hip, while dress shirts may need to extend further for tucking in.

Hacks for accurate measurements

• Take your measurements while wearing a thin shirt or a fitted undershirt. 

• Avoid bulky clothing: it can distort the results.

• For sleeve length, slightly bend your arm while measuring to make sure you can move well in the final fit.

• Stand naturally with your arms at your sides and don’t puff out your chest.
