4:5 Size in Pixels for Photography and Social Media
Learn how to calculate, convert, and use the 4:5 aspect ratio in pixels for optimized photography, social media posts, and high-quality print work.
Introduction to 4:5 Size in Pixels
The 4:5 size in pixels format is a widely used aspect ratio for images, especially on mobile-first platforms like Instagram and Pinterest. This vertical-friendly proportion not only maximizes on-screen presence but also enhances visual impact in feeds. In this guide, you'll learn how to understand, calculate, and apply the 4:5 aspect ratio across digital and print media—ensuring your visuals remain sharp, properly sized, and platform-optimized.

Understanding Aspect Ratios and the Popularity of 4:5
An aspect ratio describes the proportional relationship between an image’s width and height, expressed as two numbers separated by a colon (e.g., 4:5).
The 4:5 aspect ratio means that for every 4 units of width, there are 5 units of height—a slightly taller format compared to a square.
The 4:5 ratio has become hugely popular on social media platforms, particularly Instagram and Pinterest, for key reasons:
- Platform Optimization – Instagram’s portrait posts use a max display size of 1080x1350 px, perfectly corresponding to the 4:5 ratio.
- Attention-Grabbing Presence – Taller images take up more feed space on mobile, holding the viewer’s attention for longer.
- Balanced Composition – Offers ample canvas for vertical shots without feeling disproportionate.

Converting 4:5 Aspect Ratio to Pixel Dimensions
When referring to "4:5 size in pixels," you’re translating that proportional relationship into specific pixel counts.
Typical pixel dimensions for 4:5 include:
- 1080x1350 px – Standard Instagram portrait
- 1200x1500 px – Crisp, high-quality web display
- 1600x2000 px – For large prints or Pinterest pins
How to Calculate
You can determine dimensions using the aspect ratio formula:
height = width × (5/4)
width = height × (4/5)Example:
Width = 1080 px
Height = 1080 × (5/4) = 1350 px
Height = 2000 px
Width = 2000 × (4/5) = 1600 px

Calculating 4:5 Pixel Dimensions for Any Size
Whether prepping for social content or a custom print job, the 4:5 ratio adapts to any resolution:
- Start with your target shortest side (width for portrait, height for landscape).
- Use the formulas above to calculate the other dimension.
- Stay within platform upload limits to reduce image compression.
Pro Tip: Use a spreadsheet or aspect ratio calculator to speed up conversions, ensuring maximum accuracy without manual guesswork.

Recommended 4:5 Pixel Sizes for Major Platforms
Below is a quick reference for common applications of the 4:5 ratio:
| Platform | Orientation | Pixel Size (W x H) | Notes |
|---|---|---|---|
| Portrait | 1080 x 1350 | Maximum feed size without cropping | |
| Portrait | 1000 x 1250 | Optimized for pins, tall enough without cutoff | |
| Printing (small) | Portrait | 1200 x 1500 | Ideal for A5 or similar prints |
| Printing (large) | Portrait | 1600 x 2000 | Perfect for posters or high-resolution art |

Tips for Cropping Photos to 4:5
Cropping for a 4:5 ratio is about more than math—it’s about enhancing composition:
- Keep the main subject centered or aligned via the rule of thirds.
- Avoid chopping off important spatial elements or anatomy.
- Maintain breathing space between subject and frame edges.
- Preview in platform-specific layouts before publishing.
For portraits, ensure comfortable headroom and avoid cuts at joints or limbs.

Troubleshooting Pixel Dimension Errors and Maintaining Quality
When preparing 4:5 images, avoid these pitfalls:
- Incorrect Ratio – Even slight mismatches can trigger automatic cropping.
- Overlarge Uploads – Oversized files may be compressed, affecting quality.
- Pixelation – Always start from high-resolution originals.
- Improper Format – Use JPEG for photos and PNG for text-based graphics or transparency.
Preventative Measures:
- Verify dimensions in an image properties viewer.
- Maintain PSD or TIFF originals for future edits.
- Test posts in private drafts before publishing publicly.
