This Shirt Size Guide can be used with smart shirts and dress shirts. Both smart shirts and dress shirts should fit perfectly. But are you sure you actually use the correct shirt size?

How to Measure Men's Shirt Size?

To determine your perfect dress shirt size, you will need to take a few measurements (neck circimference , chest circumference  and arm length). Let us show you how...

Neck/collar: Measure circumference around your neck, at the Adam's apple. Keep the measuring tape a little bit loose.

Chest: Measure circumference around your chest at the fullest part, under your arms. Make sure to keep the measuring tape parallel with the floor all way around.

Arm length: Ask a friend or family member for help measuring your arm length.
Bend your arm 90 degrees and place it on your hip (just like in the illustration above). Measure from the center back of your neck, across your sholder, via your elbow and down to your wrist.

Use your measurements to determine your top size from our Men's Tops Size Charts below:
