Most people take photos the same way every time — and never think to turn on the camera grid lines already built into their phone.
The result is technically fine, but it often feels flat or uninteresting. The subject sits in the middle, the sky and foreground are split evenly, and nothing guides the viewer’s eye anywhere in particular.
A simple built-in camera setting can change this. It takes about ten seconds to turn on and costs nothing.
What the camera grid actually is
The camera grid is a feature built into the default camera app on both iPhone and Android.
When it is turned on, a set of faint lines appears on your camera screen while you are composing a shot. Two horizontal lines and two vertical lines divide the screen into nine equal sections, creating a grid that looks similar to a noughts and crosses board.
These lines do not appear in the final photo. They are only visible on screen to help you frame your shot.
Why the grid helps you take better photos
The grid is based on a photography principle called the rule of thirds.
The idea is straightforward. Rather than placing your subject dead centre, you position it along one of the grid lines or at one of the four points where the lines intersect. This creates a more natural and visually interesting composition.
Centred subjects often feel static. Off-centre subjects give the image direction and balance, and they naturally draw the viewer’s attention where you want it to go.
A few practical examples:
- When photographing a landscape, try placing the horizon on the bottom horizontal line. This fills two thirds of the frame with sky and gives the image a sense of openness.
- When photographing a person, try positioning their eyes near one of the top intersection points rather than in the centre of the frame.
- When photographing an object or subject, try placing it along a vertical line rather than directly in the middle.
None of these are strict rules. They are starting points that tend to produce more engaging results than centring everything by default.
How to turn on grid lines on iPhone
Turning on the grid on iPhone takes a few seconds.
Open the Settings app. Scroll down and tap Camera. Under the Composition section, toggle Grid to on.
Once this is done, the grid will appear every time you open the camera app. It stays on until you turn it off.

How to turn on grid lines on Android
The exact steps vary slightly depending on the phone model, but the process is similar across most Android devices.
Open the default Camera app. Tap the Settings icon, which is usually a small cogwheel in the upper corner of the screen. Look for an option called Grid lines, Grid, or Shooting grid and toggle it on.
On Samsung devices, the setting is typically found under Camera settings → Shooting methods → Grid lines.
On Google Pixel devices, open the camera, tap the settings arrow, and select Grid type.

The grid does not change the photo itself
One thing worth noting is that the grid is only a visual guide. It does not alter your photo in any way.
The lines appear on screen while you are framing the shot, but they do not show up in the image you save. You are simply using them as a reference while composing.
This also means you can leave the grid on permanently without it affecting your photos at all.
Final thoughts
The camera grid is one of those settings that is easy to overlook because nothing tells you to turn it on. But once it is enabled, it changes the way you think about framing a shot.
If your photos have been feeling a little dull or flat, try turning on the grid and experimenting with placing your subjects off-centre. It is a small adjustment that can make a noticeable difference.
