I was rewatching Interstellar the other night, not for the plot - I know it by heart at this point - but for one specific shot: the Endurance drifting silently in front of an immense black backdrop, tiny, almost lost in the frame. There's nothing else on screen. No swelling score, no text, no action. Just a metal speck and a lot, a lot of empty space. That shot probably lasts about ten seconds, which is an eternity in film time, and yet I wasn't bored for a moment. The emptiness here doesn't say "nothing." It says something very specific about scale, about solitude, about what it means to be human in front of something immeasurably larger than yourself. That feeling stuck with me into the next day, when I opened the dashboard of an internal tool I'm working on, packed with widgets, notification badges, and three stacked levels of navigation. I realized I had never managed to create, in an interface, even a fraction of the breathing room that shot gave me for free.
Why it's so hard to leave space empty
That's the question sitting with me: why is it so genuinely difficult to leave empty space in an interface? This isn't rhetorical. Every time I design something - a portfolio, a landing page, even a simple documentation page - I feel this almost physical urge to fill the available space. Is there room left at the bottom of the hero section? Let's add another tagline. Is there margin left in the sidebar? Let's drop in one more widget. That urge isn't irrational: every empty pixel feels like a missed opportunity to communicate something, to convert, to justify the time spent designing the screen. Unlike content, emptiness can't be pointed to in a meeting as a "shipped feature." That's probably the root of the problem: content is visible and measurable, negative space isn't.
Emptiness that gives things scale
What makes that Endurance shot so effective isn't the ship itself - it's the relationship between the ship and everything surrounding it. Without the black immensity around it, you'd just have a ship. With it, you get a sense of scale, fragility, distance that no amount of zooming in on the "interesting" object could ever produce. The film repeats this move several times: the tiny silhouettes on Miller's planet against mountain-sized waves, the Endurance station rotating slowly in near-total silence once we've moved from Earth's soundscape into the vacuum of space, where sound technically shouldn't even travel. Emptiness is never a lack of content; it's content in its own right, whose job is to lend relative value to whatever remains. In interface design, the principle is identical, and yet we forget it constantly: a single call-to-action button surrounded by generous space communicates an urgency and clarity that no blinking red badge could ever match in the middle of a crowded page. The space around an element isn't wasted space - it's what gives that element its hierarchy.
Minimalism doesn't mean absence
There's a common confusion, one I held onto myself for a long time, between minimalism and thin content. An empty shot in a film is almost never improvised or lazy - it's often one of the most carefully worked shots in the whole production, in terms of framing, timing, color grading, sound design (or the deliberate absence of it). Emptiness done well takes at least as much work as dense content, often more. That's essentially what Dieter Rams is getting at in his ten principles of good design, when he sums up his philosophy as "less, but better": it's not a call to put in less effort, it's a call to concentrate effort on what actually matters and rigorously strip away everything that doesn't contribute to it. In interfaces, that translates into painful decisions: removing a secondary feature from the homepage doesn't mean it has no value, it means it doesn't belong in this particular frame, at this particular moment of the user's attention.
The cost of empty space in a crowded interface
To be honest, in a lot of product contexts, emptiness has a real cost, not just an aesthetic one. A B2B dashboard displaying ten compacted metrics often has very good reasons for doing so - the power user staring at it eight hours a day prefers information density over visual breathing room, because every scroll or screen change costs more cognitively and temporally than reading one extra number. This is where the film analogy hits its clearest limit: a movie sets the pace for the viewer, an interface gets operated by someone with their own goals and their own patience. The emptiness that works beautifully on a landing page or a portfolio, where the goal is to create an impression and guide toward a handful of actions, becomes an almost guilty luxury on a work tool where every extra screen to scan carries a cost. So the right question is never "should there be empty space or not," but "exactly where does this space serve the viewer's attention, and where does it work against it."
Rhythm, not just space
One thing I underestimated before really sitting with this film is that emptiness is never static - it's part of a rhythm. Interstellar alternates extremely dense information sequences (fast, verbal scientific exposition scenes) with long, nearly silent visual breaths. It's that alternation that makes each empty shot effective: it arrives after a build-up, like a necessary release. Permanent emptiness would eventually become as tiring as permanent density - flat boredom rather than contemplation. In interface design, that translates into vertical reading rhythm: a page alternating dense blocks (text, data, a form) with breathing zones (generous margin, a near-empty section with just a heading) creates a sense of progression that neither a uniformly dense page nor a uniformly empty one can offer on its own. Emptiness only makes sense in contrast to what surrounds it.
Where emptiness works, and where it doesn't
This line of thinking pushed me to look differently at the interfaces I use every day, trying to spot where emptiness actually earns its place and where it's just an aesthetic pose borrowed from a mood board. On a portfolio or a landing page, emptiness almost always works in the designer's favor: the goal there is to create a strong impression in a few seconds and guide the eye toward one or two specific actions, exactly the way a film shot guides the eye toward a single point of interest by removing everything that could distract from it. On an editorial site or a longform page, emptiness plays a different but equally real role: the generous margins around an article, the vertical spacing between paragraphs, aren't there to look nice - they lower the cognitive load of continuous reading and give the text a breathing rhythm closer to that of a printed book. On a social feed or a news timeline, though, where the product's actual goal is maximizing continuous content consumption, emptiness becomes counterproductive from a business standpoint - every bit of unused space is a place where the user might disengage instead of keep scrolling. It's no accident that these interfaces are statistically the densest ones out there: their emptiness would be lost revenue, not breathing room.
An interpretive reading, not a method
I want to be honest about the nature of this comparison: this is an interpretive reading, not a claim about the film's intentions. Christopher Nolan and his cinematographer, Hoyte van Hoytema, compose shots to tell a story about grief, time, and survival - not to illustrate negative-space principles for user interfaces. I'm not claiming they're applying, even unconsciously, screen design rules. What I'm doing is using their work as a testing ground for a question that's very real in my own field: how do you recognize when an empty space is serving a composition rather than betraying it? Cinema, because it pushes that question to an extreme - entire minutes without dialogue, without action, without text - simply makes it more visible, easier to name.
Silence as material, not as absence
One last detail from the film is worth mentioning, because it lights up this question of emptiness from another angle: the silence of the vacuum of space isn't a gratuitous effect, it's a deliberate sound design choice that sharply contrasts with the noisy Earth-bound scenes early in the film - wind through cornfields, voices, farm machinery. Once we're in space, a huge chunk of the soundtrack disappears all at once, and that contrast makes the silence feel almost physical, almost uncomfortable, even though objectively it's nothing more than the absence of sound. That principle transfers almost directly to interface design: an empty space only lands if it contrasts with what surrounds it. A dashboard that's empty everywhere doesn't have "meaningful" emptiness - it just has a content deficit. But a single cleared-out zone in the middle of an otherwise dense interface gets noticed immediately, the same way the silence of space only works because we've just left Earth's noise behind. Emptiness is never an absolute property of a screen; it's always a property relative to whatever surrounds it.
What this actually changes
Since then, I've caught myself doing a small but useful exercise: before adding an element to a page, I ask whether I'm filling a gap because it serves something, or simply because the gap existed and leaving it alone made me uneasy. It's not an absolute rule - I still design dense interfaces where that density is fully justified. But the habit of justifying every empty space instead of filling it by default has changed how I approach even the most modest layout, quite a bit more than I expected.
