Thornhill White Shirt Sleeves Too Short: Should You Size Up Using HADUR’s Laid Flat Size Guide?

Last updated: November 4, 2026

Listen to this articleAudio version

If your Thornhill white shirt sleeves are too short, should you size up using the HADUR size guide? Not automatically: the HADUR size guide lists the sleeve separately from the collar, chest and back length, all measured on the shirt laid flat, so you can check the sleeve figure for each size before you choose. Sizing up changes the whole shirt, not only the sleeve.

Short Sleeves on a White Shirt in Thornhill: Read the Guide Before Sizing Up

The HADUR size guide gives four measurements for every size: collar, chest, back length and sleeve. Each one is taken on the shirt laid flat. That matters because a sleeve that feels too short is a sleeve problem, and the guide lets you look at the sleeve on its own.

Moving up a size also moves the collar, chest and back length. Check all four. A longer sleeve is no gain if the collar no longer suits you.

Measure a Shirt You Own, Laid Flat

The simplest way to decide whether to size up for sleeve length is to measure a shirt you already own the same way the guide does: laid flat. If you're shopping online from anywhere in Canada or the United States and can't try a shirt on first, this is the comparison that counts.

Write down the collar, chest, back length and sleeve of that shirt. Then find the size in the guide whose numbers sit closest to yours. If only the sleeve falls short, look at whether the next size's sleeve figure fixes it without pulling the other three too far away.

How HADUR Collar Sizes Are Written

HADUR sizes are collar sizes given in centimetres, with the inch size beside them. If you know your collar in inches from another shirt, you can read it straight across. Both shirts, the Camicia in bamboo fabric and the Raffinato in cotton with stretch, are white, with a non-iron finish and a refined spread collar.

The Raffinato's cotton with stretch moves with you and holds a crisp line. Whichever you pick, the sleeve decision comes from the guide's laid-flat figures.

FAQ

Does sizing up always give longer sleeves?

Sizing up for sleeve length is a choice to check, not assume: the HADUR size guide lists the sleeve for each collar size, so compare that figure directly. The collar, chest and back length change with the size too.
