Instagram Feed (portrait) Ad Size: 1080×1350 px
Aspect ratio 4:5 · 1080×1350 pixels · JPG, PNG, MP4, MOV
1080×1350 (4:5) is the tallest aspect Instagram accepts in the main feed. It takes ~25% more vertical real estate than 1:1 on mobile — the single biggest free lift in Meta creative production.
Why this size matters
Meta's own internal studies (2022-2024 platform playbook) show 4:5 outperforms 1:1 on CTR by 10–20% for most DTC verticals, purely because it occupies more scroll space. There's no downside — it center-crops cleanly to 1:1 for placements that need it.

Design tips that actually move the needle
- 01If you make ONE asset, make this one. It up-crops safely to 9:16 and center-crops cleanly to 1:1.
- 02Compose the primary subject in the middle 1080×1080 — that's what shows in 1:1 fallback crops.
- 03Product on bottom-third for scroll-stopping — it's the last thing to enter the viewport.
- 04Don't drop text below the middle — the caption teaser overlays the bottom ~10%.
- 05Use full-bleed color or product; whitespace at 4:5 looks like a mistake.
