1080 x 1350 Image Size Guide for Social Media

Mastering the 1080 x 1350 Resolution for Social Media Success

The 1080 x 1350 resolution has become a go-to format for Instagram and other mobile-first platforms due to its effective use of on-screen space and strong engagement potential. This guide explains what the 1080 x 1350 size means, how it compares to other formats, and how to design, shoot, and optimize images for maximum impact in your social media strategy.

Understanding the 1080 x 1350 Resolution

The 1080 x 1350 image size refers to a digital image that is 1080 pixels wide and 1350 pixels tall. This resolution produces a 4:5 aspect ratio, which is taller than a square but not as elongated as a story (9:16).

On social media platforms like Instagram, a portrait orientation with these dimensions takes up more vertical space in the feed compared to a square or landscape format — which can significantly impact scrolling behavior and viewer attention.

Why it matters:

• Full viewport presence: Occupies more real estate on mobile screens.
• High engagement: Taller images produce more dwell time because users see more detail as they scroll.
• Platform optimization: Instagram recommends 4:5 for single image posts.

Comparing 1080 x 1350 with Other Common Formats

Let’s break down the differences in common formats on platforms like Instagram and Facebook.

Key takeaway: The portrait 1080 x 1350 format maximizes visibility without awkward cropping, unlike landscape images, which can look compressed in mobile feeds.

Benefits of Vertical/Portrait Format for Engagement

The portrait orientation, especially 4:5 1080 x 1350, works wonders for audience retention:

1. Longer screen presence – Your post stays in the user’s viewport for more time as they scroll.
2. Better storytelling – More vertical room to add captions, branding, and key visuals.
3. Platform-friendly – Instagram algorithmically supports highly engaging formats, potentially boosting reach.

Studies show that vertical content can generate 30–40% higher engagement than square content on mobile-first networks like Instagram and Pinterest.

• Mind the hierarchy: Arrange visual elements so the eye naturally flows from top to bottom.
• Use grid overlays: Alignment helps create a professional feel.
• Avoid forced cropping: Start with high-resolution source material to prevent distortion.

Shooting Photos with 1080 x 1350 in Mind

When capturing photos specifically for the 1080 x 1350 format:

• Use portrait mode on your camera or smartphone.
• Enable gridlines to compose shots with the rule of thirds in vertical orientation.
• Frame your subjects to allow padding for later cropping.
• For DSLR/Mirrorless cameras:
• Shoot in 3:2 or higher aspect ratio RAW.
• Crop during editing to 4:5 for better precision.

Optimizing Text and Visual Hierarchy for Vertical Feeds

Vertical feeds mean users scroll quickly, so design for instant comprehension:

• Top third: Eye-catching hook or image element.
• Middle: Main content or subject.
• Bottom third: Call to action or secondary information.

Use bold typography for headings and legible fonts for smaller details. Avoid crowding; negative space guides the eye.

Compressing and Exporting for Fast Load Times

Slow-loading images can hurt engagement. Optimize before uploading:

1. Use JPEG for photo-heavy content and PNG for illustrations with transparency.
2. Compress smartly using TinyJPG, Squoosh, or Photoshop’s export features.
3. Keep image size under 1 MB without noticeable quality loss.

By balancing compression and clarity, you ensure your 1080 x 1350 images look crisp and load instantly.

Common Mistakes and How to Fix Them

Mistake 1: Stretching Images

• Avoid scaling disproportionately — always maintain aspect ratio when resizing.

Mistake 2: Pixelation

• Caused by enlarging low-resolution sources. Start with high-res originals.

Mistake 3: Wrong Aspect Ratio

• Even if width is 1080px, wrong height (not 1350px) will trigger unwanted cropping.

Fix: Use cropping tools in Photoshop, Canva, or any dedicated resizing app to reset dimensions to 1080 x 1350 exactly.

Case Studies: Effective 1080 x 1350 Posts

• Fashion Influencers: Outfit shots framed in 4:5 stay longer in feed view and show more of the subject’s look.
• Food Bloggers: Vertical plates and table arrangements better fill the frame, making food appear larger and more appetizing.
• Event Promotions: Posters in portrait mode display event info without requiring the viewer to click.

These campaigns consistently saw higher engagement metrics simply by optimizing to the 1080 x 1350 standard.
