Instagram Image Sizes 2026

Square post: 1080x1080px (1:1 ratio) — the classic feed post format
Portrait post: 1080x1350px (4:5 ratio) — takes up more feed space, better reach
Landscape post: 1080x566px (1.91:1) — wider but displays smallest in feed
Stories and Reels: 1080x1920px (9:16) — full screen vertical
Profile photo: 110x110px display (upload at least 320x320px)

Creator tip: Portrait (4:5) posts consistently outperform square and landscape in Instagram feed reach because they occupy more screen real estate, increasing the chance of a pause.

Mobile Safe Zones: What Gets Cropped

Every platform applies different cropping when displaying images at smaller sizes or on mobile. The general rule: keep your most important content — faces, text, logos — within the central 60-70% of the frame. Edges are consistently cropped or obscured by UI elements.

Creator Branding Consistency Tips

Professional creators maintain visual consistency across platforms by using the same brand colors, fonts, and template layouts across all content. A simple approach: create a master template at 1080x1080px with your brand elements, then resize and adapt it for each platform's requirements.

Frequently Asked Questions

Should I export social images as JPG or PNG?

JPG at 85-92% quality is best for photos and complex images — smaller file size with minimal quality loss. PNG is better for graphics with text or logos that need sharp edges. Most platforms internally recompress uploaded images anyway.

How often do platform image sizes change?

Major platforms update guidelines 1-2 times per year. Profile photo sizes are fairly stable; cover and banner sizes change more frequently. Always check the platform's official help centre before a major campaign launch.

Why does my image look blurry after uploading?

Blurry images usually mean your source resolution is too low. Always upload at the exact pixel dimensions specified or larger — platforms scale down well but scale up poorly. For Instagram specifically, upload at exactly 1080px wide for sharpest results.
