4 5 Size in Px Explained for Images and Social Media
Learn what 4:5 size in pixels means, why it's popular on Instagram, and how to crop, resize, and optimize vertical images for maximum impact.
Understanding the 4:5 Aspect Ratio
If you’ve ever seen the phrase 4:5 size in px when preparing or resizing images for social media, it refers to a specific aspect ratio — the proportional relationship between an image’s width and height. In this format, the width is 4 units, while the height is 5 units. The image is slightly taller than it is wide, resulting in a vertical format that is highly effective on platforms like Instagram feed posts.
Aspect ratio plays a crucial role in how your image is displayed across devices. Choosing the correct ratio prevents unwanted cropping or resizing, helping your visual content remain consistent and professional.

Converting 4:5 Aspect Ratio into Pixel Dimensions
Abstract ratios need to be converted into pixel dimensions for practical use. The 4:5 proportion can be scaled to multiple sizes without losing its vertical look. Your choice of size depends on whether you’re posting online, printing, or creating high-resolution designs.
Popular 4:5 pixel dimensions include:
| Aspect Ratio | Width (px) | Height (px) | Common Usage |
|---|---|---|---|
| 4:5 | 800 | 1000 | Web and light social media uploads |
| 4:5 | 1080 | 1350 | Instagram feed optimal size |
| 4:5 | 1200 | 1500 | High-resolution prints |
The most recommended Instagram feed size is 1080 x 1350 pixels — crisp enough for most screens while maximizing vertical visibility.

Why 4:5 Size is Popular on Instagram
Instagram’s mobile-first design makes vertical images more visually dominant in the feed. The 4:5 aspect ratio covers more vertical space than a square image without triggering cropping in the main feed view.
Benefits for Instagram
- More screen real estate: Taller posts draw user attention during scrolling.
- Better for portraits: Offers flattering proportion for humans and objects.
- Platform-native fit: Reduces the risk of important elements being cropped.

Comparing 4:5 with Other Aspect Ratios
Knowing how 4:5 stacks up against common formats helps you pick the best one for each purpose.
| Aspect Ratio | Example Pixels | Screen Coverage | Best Use Cases |
|---|---|---|---|
| 1:1 | 1080x1080 | Moderate | Grid posts, balanced layouts |
| 4:5 | 1080x1350 | High (vertical space) | Portraits, tall infographics |
| 16:9 | 1920x1080 | Wide | Videos, landscape photos |
Against square 1:1, the 4:5 orientation gives you more height within the same horizontal constraints. Compared to 16:9, it gains emphasis in vertical scrolling but sacrifices horizontal breadth.
