Creating your first shirt with our AI: shoulder width

You are creating your first LE CHEMISEUR® shirt with our AI and would like to adjust the shoulder width? This page is for you.

Best practice for the shoulder width

The top of the sleeve should meet the tip of the shoulder bone. A correct shoulder placement keeps the armhole smooth while preserving enough freedom of movement.

Trust the AI

The LE CHEMISEUR® AI builds on more than ten years of expertise and the data of over 50 000 customers - and you are covered by our Fit Guarantee.

🏋 Broad or very narrow build

Add + 1 cm for extra room or remove – 1 cm for a tidier line.

⚖ High or sloping shoulders

High, horizontal shoulders: subtract – 1 cm.
Sloping shoulders: add + 1 cm to the shoulder width (and add the same + 1 cm to the armhole height).

📏 Effect on sleeve length

Changing the shoulder width shifts the sleeve length by the same amount. If you widen the shoulder by 1 cm, shorten the sleeves by 1 cm—and vice-versa.

Measuring the shoulder width on a shirt you already own

Measure along the seam from the sleeve head to the collar seam.
