1 3 Rule in Painting: How It Impacts Portraits

If you've ever felt like your portraits just aren't coming together, the 1 3 rule might be the thing your art toolbox is missing. This rule is all about dividing your canvas or subject into thirds—literally splitting things up into chunkier, more visually appealing sections. Most people have heard of the rule of thirds in photography, but painters often use the same trick, just with a twist tailored for painting faces.

Think about a simple portrait: instead of plopping your subject dead-center, you break up the space by roughly placing important features along lines or at points that divide your canvas into three equal horizontal or vertical parts. This isn't about doing math on your art—it's about getting your viewer’s eyes to move in a way that feels natural and pleasing. And trust me, once you start spotting this pattern, you’ll see it everywhere in both classic and modern portraits.

What Is the 1 3 Rule in Painting?

The 1 3 rule in painting is a basic guideline for arranging stuff in a way that just looks good to most people’s eyes. Instead of plopping things in the center, you split your canvas or subject into three equal parts—either across, down, or both. It’s pretty much the painter’s version of the rule of thirds in photography, but it’s used a lot in portrait painting to guide where you put features like eyes, noses, and mouths.

Here’s how it usually works: you imagine your canvas has two equally spaced lines running horizontally and vertically, cutting it into a grid of nine chunks. Where these lines cross is naturally where people’s eyes like to go first when they look at art. So, if you want to make your portrait more interesting, you line up important parts—like the eyes or the face—along these invisible lines or where they meet. It feels more natural than having everything smack dab in the middle.

This simple trick isn’t just common sense—it’s rooted in a ton of visual research. For example, a study by the Gestalt psychologists in the 20th century found that viewers are drawn to off-center points, placing the rule of thirds approach just ahead of centered compositions when it comes to holding attention.

The 1 3 rule can be applied to more than just head placement. Artists use it for everything from where to put hands to how to block out backgrounds. Getting used to this, you’ll make portraits that feel more balanced and way more professional-looking. If you’re wondering if real portraits use this, grab a magazine or scroll art feeds online—the top picks almost always follow the 1 3 rule, even if it’s not obvious at first.

Why Portrait Artists Rely on This Rule

Portrait artists don’t just use the 1 3 rule because it sounds catchy. The main reason? It works. This rule helps painters avoid awkward or stiff compositions, making the person's face stand out without feeling forced or unnatural. When you line up facial features or parts of the background along these one-third marks, your viewer’s eyes move across the painting in a way that feels smooth and satisfying. Our brains actually like things that are off-center—centered stuff gets boring fast.

For example, when the subject’s eyes hit the top third of the canvas, experts say people spend up to 40% more time looking at the face. That’s a big deal if you want someone to really focus on your portrait. Take a look at this breakdown of how long viewers’ eyes linger on portraits depending on feature placement:

Another reason artists rely on the 1 3 rule is that it helps add interest, especially when painting groups or scenes with movement. Placing a head or a hand on a third line can make your work feel more dynamic and less like a passport photo. And if you look at portraits by painters like John Singer Sargent or Mary Cassatt, you’ll see the trick in action all the time. It’s a shortcut for getting strong results without a lot of guessing.

Here’s why so many artists trust this rule:

• 1 3 rule keeps compositions balanced but interesting.
• Saves time by giving you a starting point for sketching features or backgrounds.
• Makes it easier to direct where you want the viewer to look.
• Works in just about every style, whether you’re into realism, abstract, or something wild and experimental.

Real-Life Examples in Art History

If you look at some of the world’s best portrait paintings, you’ll notice that the 1 3 rule quietly shapes how the composition grabs your attention. Let’s pick apart some classic cases where artists pulled off this trick, often without shouting it from the rooftops.

Take Leonardo da Vinci’s "Mona Lisa". Her eyes sit about one-third of the way down the canvas from the top edge. This gives her a calm, balanced presence and keeps your eyes locked on her mysterious gaze. The same goes for Johannes Vermeer’s “Girl with a Pearl Earring”—her famous pearl lines up right near a third line, giving the portrait that magic touch that feels ‘just right’ when you look at it.

It’s not just a Renaissance thing, either. Over in France, Edgar Degas slid ballerinas into those imaginary thirds, making the scenes feel lively and real. Even in more modern times, look at Norman Rockwell’s cover portraits for The Saturday Evening Post. He’d balance faces or hands along those third lines, making each cover pop on magazine racks.

Here’s a side-by-side table, so you can spot this pattern quickly:

If you’ve ever visited a gallery, you’ll notice that the portraits drawing crowds usually have this built-in balance, even if viewers don’t realize why they’re so drawn in. Using these examples, try picking out the third lines next time you flip through an art book or stand in front of a portrait—it’s a game-changer for understanding why some paintings just ‘work.’

How to Apply the Rule When Painting Faces

Ready to put the 1 3 rule to work on your next portrait? Here’s how you do it without overthinking things. Start by lightly dividing your canvas into three equal parts—either vertically, horizontally, or both. You’re not carving up your art, just giving yourself subtle guidelines. Most artists will use a ruler or just estimate with a pencil line (which you erase later, of course).

The magic of the 1 3 rule in painting faces is all about placement. For vertical thirds, imagine three zones going from left to right. For horizontal thirds, think top, middle, and bottom. The key facial features—the eyes, nose, and mouth—often line up with these breaks. It gives your subject a sense of balance and keeps the portrait from feeling stiff or awkward.

• Eyes typically sit on the upper horizontal third line.
• The bottom of the nose often lines up with the second third.
• The mouth usually tracks close to the bottom third line.

These aren’t hard-and-fast rules, but starting here makes portraits look way more natural. Check famous portraits—like da Vinci’s Mona Lisa—and you’ll notice her eyes line up right around a horizontal third. No accident! Modern artists like Kerry James Marshall and Alice Neel play with these same proportions, giving their works that same satisfying feel.

"Art is not what you see, but what you make others see. Using compositional tools like the 1 3 rule helps turn ordinary faces into something viewers can't ignore." — Edgar Degas

Here’s a step-by-step rundown:

1. Sketch a light grid dividing your canvas into three rows and three columns.
2. Place your subject’s eyes along the top horizontal third.
3. Mark the nose and mouth on or near the lower third lines.
4. Position the most expressive features (a strong eyebrow arch or a dimple) where the grid lines cross—these spots draw attention.
5. Step back now and then. Once the basics are in, you can erase the guides and commit to your painting.

Just for a bit of proof: In a 2019 survey of art instructors from U.S. art schools, 68% said they teach the 1 3 rule to beginners for better portrait composition. It isn’t just tradition—they’ve tracked better student results using it.

Don’t worry if it doesn’t look perfect right away—sometimes that slightly-off placement creates energy. But keep this rule handy; it’s a true portrait painter’s hack for nailing those first impressions.

Common Mistakes and How to Avoid Them

Getting the 1 3 rule right in portrait painting feels simple, but there are a few trip-ups that catch a lot of beginners—and even experienced artists—off guard. Let's break down what can go wrong, and what you can do to sidestep these issues so your paintings look their best.

One mistake lots of artists make is lining up facial features too close together instead of using the one-third breakdown. For example, putting the eyes way too high or the mouth just a touch too low throws off the natural flow in a face. Faces are usually divided into rough thirds: hairline to eyebrows, eyebrows to base of the nose, and base of the nose to chin. If the proportions are off, you’ll quickly spot that something feels "not quite right."

Centering the subject is another pitfall. It might seem safe, but it actually zaps a lot of life from your portrait. Instead, try placing the eyes along the upper third line or nudging other features slightly off-center. This quietly adds energy without making the layout feel forced.

Ignoring the background is another biggie. Even if you nail facial proportions, keeping everything else stiff and centered makes the whole painting look flat. Think about the rule in the entire canvas, not just the face.

• Double check vertical spacing: Measure the thirds on your canvas. Make sure major facial landmarks (like eyes and mouth) sit close to those guides.
• Step back: Walk away every so often and glance at your work from a distance. Odd placements or centering jumps out more when you aren’t up close.
• Sketch guidelines: Lightly draw those thirds as lines on your canvas before starting. Erase them after you block in the basics.
• Look at real portraits: Pick a famous painting and trace the thirds with a clear ruler or even just your finger on the screen. Artists use this rule more often than you’d think.

Here’s a quick table showing where beginners most often misplace key features—plus quick reminders to help out:

If you find yourself stuck, remember: almost every art app and even your phone’s camera grid has a rule of thirds overlay. Pop a reference photo into one or just use the grid as a check-in. Tiny adjustments make portraits jump from "meh" to "wow, that actually looks right."

Tips for Breaking the Rule Effectively

Here’s the thing about the 1 3 rule: once you know it, you’re allowed to break it. In fact, some of the most striking portrait paintings go against the grain and ignore those tidy divisions. But if you want your break from the rule to look intentional—not just random—you need to have a plan.

First off, think about why you want to shift away from the rule. Maybe you want to create tension, highlight emotion, or make your viewer stop in their tracks. Famous artists like Egon Schiele or Francis Bacon did this by pushing their subjects to the edge or cropping faces in ways that feel almost uncomfortable. That jolt grabs attention.

• Start with a sketch. Lay down the classic guide first, then move features off those lines. This helps you see if the disruption feels forced or fresh.
• Play with negative space. Leaving a lot of empty room on one side can make your subject feel isolated or powerful. This works especially well if something in their pose or expression matches the mood.
• Use color or contrast. Sometimes, just shifting the main focal point away from the rule-of-thirds area and making it pop with color, can direct attention better than composition lines ever could.

It’s not just about placement, though. Data from a 2018 study by Newcastle University showed that portraits breaking traditional composition rules still scored high on emotional impact—as long as the artist had clear intent and balance elsewhere in their work. Check out the quick comparison below:

You don’t have to keep it safe. If you break the rule, do it on purpose and know what reaction you want. Try a series of rapid-fire studies pushing one feature—like the eyes—up against the edge, or experiment with big blocks of shadow that mess with the thirds. The point is, make it bold, and stand behind your choice.
