Is There a Right Lapel Width? (If yes, what is it?)

Published 3 months ago • 1 min read

Hi there,

Most men shop for jackets and focus on color, fabric, and fit. But there's one detail that is mostly overlooked: Lapel width.

Here's the problem:

You've probably heard "avoid slim lapels—go wide." But walk into most stores and that's exactly what they're selling.

However, the nuanced recommendation of Thoughtful Style is that neither extreme is right.

Neither “Only wide lapels” nor “Go with what’s available: slim lapels” is the most reasonable choice. Dogmatic "only wide lapels" ignores your individual frame and what's available. Accepting "whatever stores carry" ignores your proportions, too.

The proper lapel width depends on your build. There's no universal "correct" lapel width. A 3. inch (7,6 cm) notch lapel looks completely different on a slim man versus a large man.

So instead of following dogmatic rules, I have a recommendation that will benefit you and your silhouette far better than generic advice.

Slim to medium build: 2.95-3.5 inches (7.5-9cm)

If you have a slim to medium build plus a slim face structure, even 2.95 inches will frame your face properly. 3.5 inches is a proper width that gives your chest enough breadth without overpowering your features.

Medium build: 3.5-4.3 inches (9-11cm)

You have more flexibility. Just avoid going below 3.5 inches, which can create a visual mismatch with your frame.

Large build: 4-5.5 inches (10-14cm)

Go wide. Narrow lapels will look disproportionate. Always verify with your tailor or salesperson that the width supports your build.

Single-breasted sports jacket (3.08 in./7.8 cm lapel width) - ideal width for a slim build on a casual jacket. Balanced, not extreme.

Double-breasted blazer (3.74 in./9.5 cm lapel width) - same wearer, wider lapels to support the double-breasted structure and visual weight.

Additional considerations:

Casual sports jackets – think British country style - allow slightly narrower lapels for your build. It's a typical style. For formal pieces, if in doubt go slightly wider.
Peak lapels need slightly more width than notch lapels to unfold their visual appeal properly. Err on the slightly wider side with peak lapels.
Double-breasted jackets with peak lapels require more width to balance the overlapping fabric.

Lapel width shouldn’t be science and it shouldn’t be dogma. Choose what pleases your eye and supports your frame. There’s no real right or wrong. It’s about understanding proportion.

What other jacket details confuse you? Buttons? Vents? Shoulder construction? Reply and let me know—I might cover it in an upcoming newsletter.

Best regards,

How to choose a navy blazer? (Fabric, buttons, construction)

Hi there, The navy blazer is perhaps the most versatile sports jacket a man can own. Let me break down what actually makes one — fabric, buttons, and construction — and why those choices matter when you want to choose your navy blazer. Fabric A smooth worsted navy, a fine twill perhaps, reads more formal and works well with dress trousers and a tie. A textured fabric — hopsack, flannel, cashmere, or a linen blend — reads more casual and pairs naturally from smart wool trousers to chinos or...

Building a wardrobe beyond the essentials

Hi there, This is the third and final part of my wardrobe building series. If you missed parts one and two, you can find them in the archive. Today: the pieces that aren't exclusively about function or versatility. The ones you want simply because you want them — and what to do with that feeling. A charcoal pinstripe suit worn with a tie. My plain dark suits already cover what a pinstripe can do. But I like to wear it relaxed, too. It's a special addition, not a necessity. But that's exactly...
