💡 Pro Tips
Use 4:5 portrait for maximum feed visibility
Portrait images at 1080×1350 take up 20% more screen space than square posts. This increased visibility leads to higher engagement—users spend more time on larger images and are more likely to like, comment, and save them.
Keep safe zones in mind for Stories and Reels
The top and bottom 250 pixels of Stories/Reels are covered by Instagram's UI (username, captions, buttons). Keep important content like text, faces, and CTAs in the middle safe zone to ensure nothing gets hidden.
Maintain consistent aesthetics on your profile grid
Your profile displays posts in a 3-column grid. Mix of square and portrait images can look chaotic. Consider using consistent aspect ratios or planning your grid layout in advance. Portrait posts show the center crop on the grid.
Design carousel posts for swipeability
Start carousels with an attention-grabbing first image. Use consistent dimensions throughout (4:5 recommended). Add visual cues like arrows or 'Swipe' text to encourage engagement. Carousels get higher engagement than single images.
Optimize profile pictures for recognition
Your profile picture displays tiny in comments and explore. Use a close-up face shot or simple logo with high contrast. Avoid text or detailed graphics that become illegible at small sizes. Keep key elements centered for the circular crop.
Test images on mobile before posting
Most Instagram users browse on mobile. Preview your resized images on your phone to check quality, readability of any text, and how it appears in the feed. Colors and details can look different on mobile screens versus desktop.
