Instagram Post Size
Instagram feed posts display at 1080 px wide. The 4:5 portrait ratio (1080 × 1350 px) takes up the most screen space in the feed — which typically correlates with higher engagement. Square (1080 × 1080 px) and landscape (1080 × 566 px) formats are also supported but show smaller in the feed.

Design Tips
- →Portrait 4:5 (1080 × 1350 px) occupies the most vertical space in the scroll feed — use it for product shots, portraits, and text-led announcements to maximise stop-scroll impact.
- →In grid view, Instagram crops every post to a square thumbnail (1:1). Keep your main subject within the central 1080 × 1080 px zone of a portrait post to avoid awkward grid cropping.
- →Avoid placing text within 150 px of the edges — Instagram's UI (buttons, username overlay) can obscure corners, especially in the feed on smaller phones.
- →Export as JPG at 80–90% quality. Instagram recompresses uploads; starting with a clean high-quality export minimises visible artefacts after their compression.

Instagram feed posts are 1080 px wide. Portrait posts (recommended) are 1080 × 1350 px (4:5 ratio). Square posts are 1080 × 1080 px (1:1). Landscape posts are 1080 × 566 px (1.91:1). The 4:5 portrait format shows the largest in the feed scroll and generally performs best for engagement.
What ratio is Instagram feed post?+
The recommended Instagram feed post ratio is 4:5 (portrait) at 1080 × 1350 px. Instagram also supports 1:1 square (1080 × 1080 px) and 1.91:1 landscape (1080 × 566 px). The 4:5 ratio is the safest choice — it takes the most space in the feed without being cropped.
What is the best resolution for Instagram posts?+
Upload images at exactly 1080 px wide — Instagram displays feed images at 1080 px on most devices. Uploading larger images (e.g., 2160 px) doesn't add visible quality but increases upload time and triggers more aggressive compression. For portrait: 1080 × 1350 px. For square: 1080 × 1080 px.
