Instagram Ad Sizes & Specs (2026)
Instagram is a vertical-first, image-led platform, so the two assets that matter most are a 4:5 feed image (1080 × 1350) and a full-screen 9:16 Reels/Stories image (1080 × 1920). Because Instagram ads run through the same Meta Ads Manager as Facebook, one campaign can serve both networks — but Instagram crops more aggressively to fill the screen, and its audience expects native, editorial-looking creative rather than obvious banner ads. Square 1:1 still works but leaves black bars or a smaller footprint on modern feeds.
Instagram ad specifications
| Placement | Dimensions (px) | Aspect ratio | Max file size | File types | Body text | Notes |
|---|---|---|---|---|---|---|
| Feed image (vertical) | 1080 × 1350 | 4:5 | 30 MB | JPG, PNG | 125 chars | Recommended feed size; tallest ratio Instagram permits. |
| Feed image (square) | 1080 × 1080 | 1:1 | 30 MB | JPG, PNG | 125 chars | Classic square; safe but uses less screen than 4:5. |
| Stories | 1080 × 1920 | 9:16 | 30 MB | JPG, PNG | 125 chars | Keep key content in the middle; ~14% top and ~20% bottom are covered by UI. |
| Reels | 1080 × 1920 | 9:16 | 30 MB | JPG, PNG | 125 chars | Full-screen; bottom-right and lower third overlap caption and CTA. |
| Explore | 1080 × 1350 | 4:5 | 30 MB | JPG, PNG | 125 chars | Served after a user taps into an Explore post; uses feed asset. |
| Carousel card | 1080 × 1080 | 1:1 | 30 MB | JPG, PNG | 125 chars | 2–10 cards; all cards share one aspect ratio (1:1 or 4:5). |

Tips for Instagram ad creative
- Design for 4:5 (1080 × 1350) in feed — it is the tallest ratio Instagram allows and dominates the mobile screen.
- For Reels and Stories, keep text and CTAs inside the central safe zone; the bottom ~250 px is covered by the caption, profile and CTA sticker.
- Instagram captions can be long, but only the first ~125 characters show before “more” — lead with the hook.
- Avoid heavy on-image text and hard sales framing; creative that mimics organic Reels tends to outperform polished banners.
Instagram ad size FAQ
What size is an Instagram ad?+
The recommended Instagram ad size is 1080 × 1350 pixels (4:5) for feed and 1080 × 1920 pixels (9:16) for Stories and Reels. Square 1080 × 1080 (1:1) also works in feed. Upload at least 1080 pixels on the shortest edge for a sharp result.
What is the best Instagram ad size in 2026?+
For feed, 1080 × 1350 pixels (4:5) is the best size because it takes up the most vertical space on a phone. For full-screen placements, 1080 × 1920 pixels (9:16) is best. Supplying both covers every Instagram placement.
What aspect ratio do Instagram Story ads use?+
Instagram Story and Reels ads use a 9:16 aspect ratio at 1080 × 1920 pixels. Keep important text and buttons within the central safe area, because the top and bottom of the frame are covered by the profile bar and the call-to-action.
What is the maximum file size for an Instagram image ad?+
Instagram image ads can be up to 30 MB in JPG or PNG format. Because Instagram is image-first, upload the highest-resolution version you have so the creative stays crisp on high-density displays.
Can I use the same creative for Facebook and Instagram ads?+
Yes. Instagram ads run in Meta Ads Manager alongside Facebook, so one 4:5 and one 9:16 asset can serve both. Instagram crops more tightly to fill the screen, so check the placement preview before publishing.
