How to Measure Your Chest for Size 40

To know for sure if you need a size 40, take your chest measurement correctly:

Get a soft measuring tape — the kind used by tailors, not a rigid builder's tape.
Stand naturally with your arms at your sides. Don't flex or hunch.
Wrap the tape around the fullest part of your chest, just under your armpits and across your shoulder blades.
Keep one finger under the tape for breathing room. This "ease allowance" prevents the shirt from feeling tight when you sit or reach.
If your measurement is 39.5–40.5 inches, you are a size 40.
If you are between sizes (e.g., 40.5–41 inches), always size up to 42 rather than squeezing into 40.
