Should Your Professional Headshot Look Serious or Smiling?

People usually frame this as a binary: smile, or don’t. Some arrive convinced a serious expression signals authority. Others assume a big smile is the safer, more approachable choice. Neither answer is universally right, because the question itself is incomplete. The better question isn’t which expression looks more professional — it’s what you want someone to feel in the second before they read anything else about you.

Every profession starts a different relationship

A financial advisor is asking someone to trust them with decades of savings. A physician meets people during some of their most vulnerable moments. An attorney often needs to project authority before saying a word. A designer or creative director might need warmth and approachability more than gravitas. None of those introductions are interchangeable, and treating “smile or don’t smile” as a universal rule ignores the fact that different professional relationships start from different emotional places.

This is why a good headshot decision starts with a question that has nothing to do with facial expression: what relationship is this photo trying to begin? The expression follows from that answer — it doesn’t precede it.

Genuine beats generic, in either direction

Expression is more personal than most people assume. Some people naturally smile with their whole face; others communicate warmth in a quieter, more controlled way. Neither is better. What consistently reads poorly on camera isn’t a serious expression or a restrained smile — it’s a manufactured one. Viewers may not be able to articulate why a photo feels slightly off, but they’re remarkably good at detecting a smile that isn’t real, or a serious expression that’s actually just tense.

That’s a practical argument against defaulting to “just smile big” as a blanket instruction. A forced smile often undermines the goal it’s meant to serve — approachability — because it reads as performance rather than warmth. The expression that works is the one that’s native to you, tailored to the specific relationship this photo needs to start.

A closer look at what “serious” actually communicates

It’s worth separating “serious” from “stern,” because the two get conflated more often than they should. A serious expression, done well, reads as composed, focused, and credible — the kind of presence you’d want from someone handling something important on your behalf. A stern expression, by contrast, reads as closed off or unapproachable, which works against almost every professional relationship except a narrow set of contexts. The difference between the two often comes down to the eyes specifically — a serious expression maintains warmth in the eyes even without a smile on the mouth, while a stern one doesn’t. That distinction is subtle to describe and easy to see when you compare two photographs side by side, which is why this decision benefits from being made in the room, with real images, rather than decided in the abstract beforehand.

The middle ground most people actually end up choosing

In practice, the strongest choice for many professional headshots isn’t a full smile or a fully composed expression — it’s something in between, sometimes called a soft smile or a closed-mouth smile. It reads as approachable without tipping into overly casual, and composed without tipping into cold. This isn’t a rule to apply universally, but it’s worth knowing that the binary framing of “smile or serious” often understates how much range actually exists between those two poles, and that range is where a lot of the strongest, most versatile headshots actually land.

What a strong session actually does

Toward the end of a session, it’s common to compare a handful of expressions side by side — a warmer option, a more composed one, maybe something in between. The useful question at that point isn’t “which smile is bigger” or “which looks more polished.” It’s “which one feels like me, doing the introduction I actually need to make.” That’s a different filter than picking the most conventionally attractive frame, and it consistently produces a better final choice.

This is also where having more than one strong option matters. A photo for a company’s leadership page might call for something more composed than the photo used on a personal LinkedIn profile. Neither expression is more “you” than the other — they’re serving different contexts, the same way a formal introduction and a casual one both come from the same person without being identical.

A caution worth naming directly

There’s a version of this that goes wrong in a predictable way: someone decides in advance, based on advice they’ve read somewhere, that their industry “requires” a serious expression — and shows up performing gravity rather than actually feeling composed. The result usually looks tense rather than authoritative, because the expression is being manufactured rather than genuinely felt. The fix isn’t abandoning the goal of looking composed. It’s getting there through an actual sense of being settled and present, rather than through a facial expression rehearsed in advance and held in place for the camera.

How to think about this before the session, without overthinking it

You don’t need to arrive with a decided expression, and trying to plan one out in advance tends to backfire for the same reason rehearsed poses do — it introduces a layer of performance that a viewer can usually sense. What’s actually useful to think through beforehand is simpler: picture the specific person who’s going to see this photo and decide whether to reach out. What do you want them to feel in that moment — reassured, impressed, put at ease, taken seriously? That answer, brought into the session as a loose intention rather than a rehearsed pose, tends to produce a far more genuine result than trying to control your face directly.

The long game

A headshot outlives the moment it’s taken by years. It sits on LinkedIn, a company website, a conference program, a press bio — doing the work of introducing you long after the session itself is forgotten. The expression that holds up over that stretch of time isn’t the one that looked most dramatic in the moment. It’s the one that still feels accurate a year later, when a client who’s never met you finally does, and the in-person version matches what the photo promised.

The bottom line

Don’t start with “smile or serious.” Start with the relationship you’re trying to begin — trust, authority, approachability, warmth — and let the expression follow from that. The right choice is rarely the biggest smile or the most composed stare. It’s whichever one is actually true to how you introduce yourself, translated into a single frame.
