2026 Social Media Image & Banner Size Guide for Creators

Nothing ruins a great design faster than having key text cut off by a circular profile avatar, a mobile navigation bar, or compression artifacts from uploading the wrong canvas size.

Platforms update their UI layouts frequently. Here is the verified dimension and aspect ratio guide for social media imagery in 2026.

1. Instagram Dimensions

• Feed Square Post: 1080 x 1080 px (1:1 aspect ratio)
• Feed Portrait Post: 1080 x 1350 px (4:5 aspect ratio) - *Recommended for maximum screen real estate on mobile feeds.*

Exporting for Maximum Sharpness

When exporting from your editor:

• Always design at 2x resolution if you plan to export text-heavy graphics.
• Use PNG for crisp graphics with typography, or high-quality WebP/JPG (85-90% quality) for photos to prevent platform re-compression.
• Test how your graphic appears on a mobile screen before posting.
