The rule of thirds is the most widely used composition in photography. The idea: imagine lines dividing the frame into thirds both ways, then place your subject on one of the four points where those lines cross.

Turn on the grid in your phone’s stock camera and you get exactly this 3×3 set of lines. In other words, you can start using it today with no extra tools.

Why the intersections work

Putting your subject dead center reads strong and direct, but it can also feel static and overly explanatory. Shift it slightly onto an intersection and open space appears on the other side, so the eye flows naturally toward the subject and the whole shot looks more assured. When you do want the subject to hit hard, a center composition lands powerfully too (→ Center composition).

How to use it

First, turn on the grid lines. Next, line your subject up with one of the four intersections. Match a horizontal grid line to anything that should be level (a horizon, a table edge) to avoid tilt. For landscapes, drop the horizon to the lower line when you want more sky, or raise it to the upper line when you want more ground.

A note of caution

The rule of thirds isn’t a cure-all. When you want a subject to feel bold, or to bring out the beauty of symmetry, a center composition can suit better. Start with the rule of thirds as your default and switch as the scene calls for it.

There’s also a more refined idea called the “golden ratio” that takes the rule of thirds a step further. Pros keep it in mind, but in practice the rule of thirds is plenty to start (→ Golden ratio).

Start with just this

Turn on the grid, line your subject up with one of the four intersections, and keep a horizontal line level. Remember “when in doubt, rule of thirds first,” and you’ll get a steady, balanced shot of almost anything.

FAQ

What is the rule of thirds?

The rule of thirds places your subject on one of four points where lines dividing the frame into thirds cross. Turn on the grid in your phone's stock camera and you get exactly this 3×3 layout, so you can start using it right away.

Why does the rule of thirds look good?

Placing the subject dead center reads strong but can feel static and overly explanatory. Shift it onto an intersection instead, and open space appears on the other side — the eye flows naturally to the subject and the shot looks more assured.

How do I use the rule of thirds?

Turn on your grid lines, then line the subject up with one of the four intersections. Match a horizontal line to anything that should be level, like a horizon or table edge, to avoid tilt.

What kinds of photos is the rule of thirds good for?

Almost any subject — food, landscapes, people, products. When you're not sure where to put something, reach for the rule of thirds first and your shots will stay reliably balanced.

Do I always have to put the subject exactly on an intersection?

No, it's only a guideline. When you want to emphasize the subject head-on, a center composition sometimes works better.

I placed the subject on an intersection but it still looks unsteady — why?

Often it's the horizontal that's slightly off. Try lining a grid line up with a table edge or the horizon. If it's still off, check whether the open space ended up on the wrong side of your subject's gaze or motion.
