1350 x 1080 Image Size for Instagram Feed Posts

Introduction to 1350 x 1080 Resolution and Aspect Ratio Basics

In the fast-moving world of social media marketing, image sizing directly impacts how your audience perceives and engages with content. Among the countless dimensions available, 1350 x 1080 pixels has become the go-to resolution for Instagram portrait feed posts. This size corresponds to a 4:5 aspect ratio — Instagram’s own recommended portrait orientation — providing more on-screen presence than the standard square, without triggering any automatic cropping.

If you’ve ever wondered why some posts demand your attention while others fade into the feed, the difference often lies in how much vertical screen space they occupy. In this guide, you’ll learn why the 1350 x 1080 format is so effective, how to prepare your visuals for it, and ways to avoid common pitfalls so you can improve your social presence.

Pixel Dimensions and Their Relation to Aspect Ratios (4:5)

The term 1350 x 1080 describes the height (1350 pixels) and width (1080 pixels) of your image. This ratio of width to height equates to 4:5, and it carries specific design implications:

• For every 4 units of width, there are 5 units of height.
• Instagram caps portrait feed photos at 4:5 to maintain feed balance.
• Any image taller than 4:5 gets cropped automatically.

Here’s a quick reference for common aspect ratios:

Why 1350 x 1080 is Optimal for Instagram Feed Posts

Instagram’s feed algorithm rewards content that creates longer on-screen engagement. With 1350 x 1080, your photo uses the tallest allowable portrait dimension — making it more noticeable than square or horizontal formats.

Advantages include:

• Scroll-Stopping Potential: It naturally holds the viewer’s attention for longer.
• Maximum Feed Presence: Uses the full portrait height without unintended cropping.
• Flexible Framing: Suitable for portraits, detailed product photography, and infographics.

Benefits of Using 4:5 Images for Engagement and Visibility

For both creators and marketers, 4:5 imagery delivers tangible advantages on Instagram:

1. Boosted Engagement: Vertical images often outperform horizontal ones in likes, comments, and shares.
2. Expanded Storytelling Room: Allows you to include both focal subjects and contextual background.
3. Enhanced Readability: More space means you can use larger, more legible text in overlays.

The 1350 x 1080 size maximizes both visual impact and functional display on mobile screens, where most Instagram use occurs.

Best Practices for Exporting Images at 1350 x 1080 Without Quality Loss

You can’t just resize to 1350 x 1080 and expect perfection — careful export ensures sharp, vibrant images:

• Work From High-Resolution Originals: Reduces loss during downsizing.
• Stick With sRGB Color Profile: Ensures consistency across devices.
• Select Optimal JPEG Quality: Around 80–90% strikes a balance between clarity and file size.
• Resize Once Only: Multiple resizes degrade quality.

In Photoshop, for example:

File > Export > Save for Web (Legacy) > JPEG > Quality: 85 > Resize to 1080 x 1350 px
