Instagram never stops evolving. From Reels to Stories, the platform is always testing new ways for brands to grab attention.

The latest update introduces a striking new 5120x1080 format — an ultra-wide aspect ratio designed for bold, cinematic storytelling.

If you’re wondering what this means for your business and when to use it, here’s the breakdown.

What Is the 5120x1080 Format?

Traditionally, Instagram content has been vertical (1080x1920) or square (1080x1080).

The 5120x1080 format flips the script: it’s ultra-wide, stretching across the feed like a panoramic banner.

Think:

• Expansive landscape photography 🌄

• Cinematic product reveals 🎬

• Wide-angle event shots 🎉

• Split-screen creative concepts ✨

It feels premium, different, and instantly attention-grabbing.

Why Instagram Added This Format

As TikTok, YouTube, and other platforms compete for attention, Instagram wants to give creators more tools to stand out visually. The 5120x1080 format:

• Creates a more immersive, cinematic experience

• Helps brands showcase bigger stories in one frame

• Encourages experimentation with carousel storytelling

For London businesses, it’s a chance to look ahead of the curve while competitors are still sticking to the standard post sizes.

When to Use the 5120x1080 Format

Not every post needs to be ultra-wide. Save this format for content that really benefits from scale:

• Campaign launches: Make new products feel larger-than-life with a dramatic, widescreen reveal.

• Events & experiences: Hospitality venues, retail activations, or live events look spectacular in panoramic shots.

• Before/after or side-by-side comparisons: Show two perspectives at once in a clean, wide layout.

• Creative storytelling: Use carousels to swipe through sections of one long, seamless image.

Best Practices for Brands

• Prioritise quality visuals: Not every photo will work in this ratio — invest in wide-angle photography or edited graphics.

• Pair with strong captions: Use keyword-rich copy so the algorithm understands your content.

• Add alt text: Describe what’s happening in the frame for accessibility and discoverability.

• Use sparingly: Keep the format for special occasions so it feels fresh and unique.

Final Word

The new 5120x1080 format is a bold creative tool — but it’s not meant for everyday posting. Think of it as your campaign spotlight, designed to tell stories that deserve a wider stage.
