How to Use the Camera Grid and Level for Straighter Photos
Turn on the camera grid and level on iPhone and Pixel, use them to keep horizons flat, pick an aspect ratio, and fix tilted shots in the Photos editor.
A tilted horizon is one of the easiest flaws to spot in a photo and one of the easiest to prevent. Both iPhone and Pixel cameras include on-screen guides for exactly this: a grid that divides the frame and a level that tells you when the phone is straight. Neither is turned on in a way most people notice, so many photographers never use them.
This guide shows where each setting lives, what the guides actually tell you, and how to straighten a shot after the fact if one slips through.
On iPhone: Grid and Level are one setting
Apple's camera guide says you "can display a grid or level on the camera screen to help you straighten and compose your shot." To turn them on:
- Open the Settings app.
- Tap Camera.
- Turn on Grid and Level.
The grid overlays lines on the viewfinder so you can line up horizons, buildings, and table edges. The level gives you a direct signal when the phone is held flat to the scene, which helps most when there is no obvious straight line to lean on, such as a beach horizon in haze.
On Pixel: Framing hints plus a separate grid
Pixel splits these into two features.
Framing hints (the level). Google's Pixel Camera Help describes it this way: when you hold the phone steadily, "A yellow line and a white line appear in the middle of the screen," and "your phone will be straight when the two lines meet, and the angle is zero." If you point the phone up or down, an "Up/Down" indicator appears so you can square the phone to the subject. Framing hints are controlled under Settings > More settings in the Camera app.
Grid lines. In the Camera app, tap Settings at the bottom left, then More Settings > Grid type, and choose the grid you want. Google lists this under "Use gridlines to straighten photos."
How to use the guides when you shoot
- Pick one straight line in the scene. A horizon, a doorframe, the edge of a table, or the top of a wall.
- Line it up with a grid line. Horizontal subjects go along a horizontal grid line; vertical ones along a vertical line.
- Check the level before you press the shutter. On Pixel, wait for the two lines to meet. On iPhone, watch the level indicator.
- Square up for flat subjects. For documents, menus, or artwork on a wall, use the Pixel Up/Down indicator, or hold the iPhone parallel to the surface, so edges do not lean inward.
- Place your subject on a line, not in the dead center, when you want variety. The grid gives you natural spots to put a person or a landmark. This is a taste choice, not a rule, but the lines make it easy to repeat.
Choose an aspect ratio before you shoot
The shape of the frame affects how much of the scene fits around your straight lines.
- iPhone: Apple's guide lists 1:1, 4:3, and 16:9. Open the camera tools (tap the Camera Controls button or swipe up from the modes), tap Aspect, then pick a ratio.
- Pixel: Google lists two options in the Camera app settings: Wide crop (16:9) and Full image (4:3).
A quick calculation shows what the wider shapes give up. If the width of a 4:3 frame stays the same, switching to 16:9 keeps 75 percent of the height (because 9/16 divided by 3/4 equals 0.75), so you lose a quarter of the picture top to bottom. Switching from 4:3 to 1:1 keeps the full height but only 75 percent of the width. If you are unsure, shoot in 4:3 and crop later.
| Ratio | Compared with 4:3 at the same height or width | Good for |
|---|---|---|
| 4:3 | Full frame | Keeping options open |
| 16:9 | 75 percent of the height | Wide landscapes, phone wallpapers |
| 1:1 | 75 percent of the width | Square posts, centered subjects |
Fix a tilted photo afterward
If a horizon still comes out crooked, the editor can rescue it.
On iPhone, Apple's Photos guide says you can "straighten a photo or video, or tilt it vertically or horizontally." Open the photo, tap Edit, tap the crop button, then tap a button below the frame to straighten, tilt vertically, or tilt horizontally, and drag the slider. Tap the same button to compare with the original, then tap Done, or Reset to start over.
Apple also notes that when you drag a crop corner, the crop keeps the original aspect ratio unless you unlock it with the lock icon, and preset ratios such as Square, 9:16, and 5:7 are available.
Straightening always trims a little from the edges, because a rotated rectangle has to be cropped back into a level one. That is one more reason to get it right in the camera: the level costs you nothing, while fixing it later costs you part of the frame.
A one-minute setup checklist
- iPhone: Settings > Camera > turn on Grid and Level.
- Pixel: Camera app > Settings > More Settings > Grid type, and leave Framing hints on.
- Choose 4:3 unless you know you need square or wide.
- Before each important shot, line up one straight edge and check the level.
Key takeaways
- iPhone puts Grid and Level together under Settings > Camera.
- Pixel uses Framing hints as its level (two lines meet at zero degrees) and a separate Grid type setting.
- Line up one straight element in the scene with a grid line, then confirm with the level before shooting.
- 16:9 and 1:1 each keep only 75 percent of a 4:3 frame in one direction, so 4:3 leaves the most room to crop later.
- The iPhone Photos editor can straighten and fix vertical or horizontal tilt, but every correction trims the edges.
