4:5 Size Ratio Guide for Social Media Images

Understanding the 4:5 Size Ratio for Social Media Images

The 4:5 aspect ratio is a highly effective image format for social media marketing, giving your content maximum vertical space in feeds without awkward cropping. This proportional relationship means the height is 1.25 times the width, creating a taller-than-square frame ideal for mobile viewing. For platforms like Instagram, Facebook, and Pinterest, understanding and using the 4:5 size ratio can significantly improve your visual strategy and engagement rates.

What is the 4:5 Aspect Ratio?

An aspect ratio defines the proportional relationship between an image’s width and height. For 4:5:

• Width: 4 units
• Height: 5 units

This format is taller than a square (1:1), yet shorter than extreme portrait formats.

Common uses include:

• Instagram feed posts
• Pinterest pins
• Facebook vertical image ads

The 4:5 ratio is favored for maximizing on-screen real estate without cropping or blank space, ensuring your visuals appear exactly as intended.

Benefits of the 4:5 Ratio for Engagement and Visual Impact

Choosing 4:5 isn’t just aesthetic — it’s strategic:

• Improved engagement rates: Taller posts command more feed space, increasing scroll-stopping potential.
• Better storytelling: Ample vertical room accommodates richer visual narratives.
• Enhanced detail visibility: Ideal for portraits, product showcases, and detailed infographics.

Studies consistently find vertical formats outperform horizontal ones on mobile-first platforms, especially where thumb-scrolling dominates.

Dimensions in Pixels: The Gold Standard

For optimal results, prepare your 4:5 images at precise pixel dimensions:

• Most recommended size (Instagram): 1080px width × 1350px height
• Alternative options (ratio preserved):
• 800px × 1000px
• 1200px × 1500px

Avoid uploading widths below 1080px to retain sharpness and prevent pixelation.
