How to Make AI Images That Actually Perform on Instagram

Instagram's rules haven't changed

• Faces beat objects.
• High contrast beats low contrast.
• One clear focal point beats three competing ones.

AI doesn't change any of that. It just gives you more shots on goal.

Aspect ratios that work

• 4:5 (1080×1350) — the tallest format the feed allows. Takes up the most screen real estate.
• 1:1 (1080×1080) — safe default, great for grids.
• 9:16 (1080×1920) — Stories and Reels only.

Generate in 3:4 in Imagoat, then let Instagram's crop handle the last 5 % — it's close enough to 4:5 that the difference is invisible.

Prompts that stop the scroll

Add these words to your positive prompt when generating for feed:

• "high contrast lighting"
• "bold color palette"
• "eye-level portrait"
• "shallow depth of field"

Faces should look at the camera. Products should have negative space around them for caption overlays.

The 3-post workflow

1. Generate 12 images from 4 prompt variations.
2. Pick the 3 best.
3. Post as a carousel with a strong hook slide first.

Carousels outperform single-image posts by roughly 3× on reach as of 2026 — the algorithm rewards time-on-post.
