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.
