Creating your first shirt with our AI : armhole height measurement

The Ideal Armhole Height

Are you creating your first LE CHEMISEUR® shirt with our AI sizing system and would like to check the armhole height? This page is for you.

Best practice for the armhole

The armhole height is the distance of the opening between the sleeves and the body of the shirt. It must allow good freedom of movement while limiting excess fabric. Changing the armhole height also affects the whole upper part of the sleeve around the biceps.

Trust the AI

Our AI is based on more than 10 years of experience and data from over 50,000 customers.

For most men, it provides an excellent armhole height recommendation.

🔃 High or sloping shoulders

If you have particularly high shoulders, you may reduce the armhole height by 1 cm.

If you have noticeably sloping shoulders, you may increase it by 1 cm.

🥵 You prioritise comfort and tend to get warm easily

Adding 1 cm can provide additional ease and improve airflow around the armhole.

😎 You prioritise style and prefer slim-fitting sleeves

You may reduce the armhole height by 1 cm for a more fitted look.

We do not recommend reducing it further, as a 1 cm adjustment already has a significant effect on this measurement.

Measuring the armhole height on an existing shirt

The armhole is difficult to measure precisely, but here's how to proceed: pull slightly on the fabric to lay the shirt flat. Measure the entire length following the seam. Do not stop at the bottom at the sleeve seam, but take the full width.
