    Instagram posts perform best at 1080×1080 pixels. Larger images are automatically compressed by Instagram, which can reduce quality. Square images fill the most screen real-estate in the feed, making them ideal for engagement. Always use high-resolution source images and avoid excessive text overlays that may become unreadable after compression.

    Design Tips for Instagram Post

    • Keep key elements centered — the circular profile picture crop may obscure corners in some views.
    • Use bold, contrasting colors that stand out in a fast-scrolling feed.
    • Limit text overlays to short, impactful phrases that remain readable at phone screen widths.
    • Test your image at thumbnail size since it appears smaller in profile grids.

    Common Mistakes to Avoid

    • Uploading images smaller than 1080px wide, causing Instagram to upscale and blur them.
    • Using too much text — Instagram's algorithm may reduce reach for overly text-heavy images.
    • Ignoring the profile grid crop that shows a center-weighted square thumbnail.

    File Size Recommendations

    Instagram accepts uploads up to 30 MB but compresses images to JPEG at roughly 70% quality. Upload at 1080px width minimum for best results. PNG works better for graphics with sharp text.
