Need to resize your images?
Use Batch Resize to resize to the exact Instagram Ads dimensions, or Crop & Ratio to crop to the right aspect ratio first.
1080x1080 px (1:1 square) is the most versatile Instagram ad format — it works in Feed, Explore and Search placements. Instagram also supports 1080x1350 (4:5 portrait) which takes up more screen space in the feed and can increase engagement by 15-20% compared to square.
1080x1920 px (9:16 ratio) for full-screen display. Keep important content within the center safe zone — the top 14% (username bar) and bottom 250px (swipe-up CTA) are covered by Instagram's UI. Compress with SammaPix to under 250 KB for instant loading between organic Stories.
Each carousel card should be 1080x1080 px (1:1). Instagram requires all cards to use the same aspect ratio. You can use 2-10 cards per carousel. Use SammaPix Batch Resize to prepare all cards at the same dimensions and compress them simultaneously.
Three principles: (1) use scroll-stopping visuals with high contrast against Instagram's white feed background, (2) keep text minimal — Instagram's old 20% text rule is relaxed but text-heavy images still perform worse, (3) include a clear focal point. Compress with SammaPix to ensure the image looks sharp after Instagram's recompression.
Yes, Instagram recompresses all uploaded images regardless of original quality. This means pre-compressing with SammaPix at 85% quality actually produces a sharper final result — you control the compression instead of letting Instagram's aggressive algorithm decide. Upload at exact recommended dimensions to avoid rescaling artifacts.
