Enter your neck, chest, and sleeve length and the tool returns your size in US (15.5/33), UK, and EU (cm). It also flags slim-fit vs regular-fit vs tailored adjustments per brand.

Frequently Asked Questions
What does '15.5/33' mean on a dress shirt?
15.5-inch neck, 33-inch sleeve length. American dress shirts pair these two numbers; European brands use neck size in cm only.
Should I size up for slim-fit dress shirts?
Same neck size, but check the chest spec — slim fit cuts run 1–2 inches narrower in the body than regular fit. If you're between, size up the body and tailor at the waist.
How do I measure my sleeve length?
From the center of the back of your neck, across the shoulder, down the arm to the wristbone with the arm slightly bent.
How accurate is this calculator?
Within half a size for 90%+ of dress shirt brands. Match it against the brand's chart for slim and tailored fits, where shoulder width is critical.
