Quick answer: Feed ads need 4:5 at 1440×1800 px. Stories and Reels need 9:16 at 1440×2560 px. Carousels need 4:5 at a minimum of 1080×1080 px per card. Get these wrong and Instagram crops or degrades your creative automatically.

Feed Image Ads
Feed ads are the most common Instagram format. The right dimensions keep your creative sharp and fill vertical screen space.
Recommended dimensions
Per Meta's Ads Guide, Feed image ads should be 1440 × 1800 pixels at a 4:5 aspect ratio. The minimum width is 500 px. Meta applies a 1% aspect ratio tolerance, so minor variation won't trigger rejection.
Aspect ratio details
The 4:5 portrait ratio gives you more vertical screen real estate than a square. That matters in a fast-scrolling feed. Uploading a square (1:1) image won't get rejected, but you leave screen coverage on the table.
File requirements and safe zones
Images must be JPG or PNG, up to 30 MB. Instagram automatically resizes images above 1080 px wide, which can reduce sharpness. Stick to 1440 × 1800 px from the start. Keep important text and logos away from the very edges of the frame.
Instagram Stories Ads
Stories run full-screen. Wrong dimensions add black bars or crop your logo.
Full-screen vertical format
Per Meta's Ads Guide, Stories image ads should be 1440 × 2560 pixels at a 9:16 ratio. Image ads display for 5 to 16 seconds before the next story plays.
Text and logo safe zones
Keep all text and logos out of the top 14% of the frame (roughly 250 px) and the bottom 20% (roughly 340 px). The Stories UI places the profile icon, mute button, and CTA button in those zones. Anything in those areas will be covered.
Video duration and file specs
Stories video ads also use 9:16 at 1440 × 2560 px. Videos under 35 seconds play in full. Longer videos auto-split into multiple Story cards. Maximum file size is 4 GB. Use H.264 compression for reliable playback.
Instagram Reels Ads
Reels ads fill the entire screen. Safe zone rules here are stricter than Stories.
Video and image specs
Both image and video Reels ads use 1440 × 2560 pixels at 9:16. Video Reels ads support up to 15 minutes. Use MP4 or MOV format.
Full-screen requirements
Any creative not built at 9:16 gets cropped or pillarboxed automatically by Instagram. Build native or resize before upload. There is no graceful fallback for wrong ratios here.
Safe zones for text overlays
Per Meta's Ads Guide, keep all text and graphics clear of the top 14%, the bottom 35%, and 6% on each side. The Reels UI stacks account handles, captions, sound attribution, and reaction buttons inside those zones. One more rule. Reels ads cannot include licensed music, face or camera effects, or GIFs.
Carousel Ads
Carousel ads let you show 2 to 10 cards in a single unit. Each card follows the same dimension rules.
Multiple card handling
All cards in a carousel must share the same aspect ratio. Mixing ratios causes Instagram to crop or pad individual cards. Keep every card consistent from the start.
Dimension requirements per card
Per Meta's Ads Guide, the minimum resolution per card is 1080 × 1080 pixels at a 4:5 ratio. The 1% aspect ratio tolerance applies to each card individually.
File and text limits
Image cards. JPG or PNG, up to 30 MB. Video cards. MP4, MOV, or GIF, up to 4 GB, between 1 second and 2 minutes per card.
Why Size Matters and How to Adjust Fast
Wrong dimensions don't just look bad. They cut into performance before a single person even sees your offer.
Common sizing mistakes and consequences
Uploading a horizontal 16:9 image to a Stories slot adds black bars top and bottom. That kills immersion fast. Feed images at 1:1 leave vertical screen space unused. Reels ads built at 4:5 get cropped right into your headline or CTA text.
