1080x1350 Aspect Ratio Guide for Social Media Posts

Introduction to Aspect Ratios and the Power of 1080x1350

In social media marketing, aspect ratios play a critical role in how visual content is displayed and consumed. An aspect ratio defines the proportional relationship between the width and height of an image or video, expressed as two numbers separated by a colon — for example, 4:5, 16:9, or 1:1.

For vertical feed posts, the 1080x1350 aspect ratio (a 4:5 ratio) has emerged as a performance-driving standard on platforms like Instagram, LinkedIn, and Facebook. This size maximizes on-screen presence without triggering unwanted cropping, ensuring your carefully crafted imagery gets the engagement it deserves.

Understanding 1080x1350 in Pixels and Inches

A 1080x1350 image is 1080 pixels wide and 1350 pixels tall. While the pixel dimensions are fixed digitally, the physical size depends on your print resolution (DPI):

• At 72 DPI (standard for web): approximately 15 x 18.75 inches
• At 300 DPI (standard for print): approximately 3.6 x 4.5 inches

From a ratio perspective:

Width : Height = 1080 : 1350 = 4 : 5.

This proportion makes it taller than a square (1:1) but shorter than a full portrait format like 9:16, which is preferred for stories, reels, and vertical videos.

How to Resize or Crop Without Quality Loss

Follow these steps to keep images crisp:

1. Duplicate the original file before editing (non-destructive workflow).

Image Compression for Web Performance

Optimizing for speed without hurting clarity is essential:

Common 1080x1350 Mistakes to Avoid

Keep your visuals flawless by steering clear of:

• Filling the frame too tightly, leaving no buffer for auto-cropping.
• Ignoring safe zones, resulting in cut-off text or faces.
• Upscaling low-res images, which can cause pixelation.
• Skipping embedded color profiles, leading to muted tones upon upload.

Scheduling Strategy for 4:5 Content

The timing of posting matters as much as the content:

• Post during peak audience hours for each platform.
• Establish thematic formats — e.g., “Inspiration Monday” posts always in 4:5.
• Reinforce feed posts with vertical Stories to capture secondary views.
• Continuously monitor analytics and refine timing.

Expert Insight: Consistency in aspect ratio strengthens brand recognition over time.
