ToolBox Image — Come ridimensionare le immagini per i social media nel 2026 — Guida completa alle dimensioni

Every social media platform has specific image dimension requirements. If you upload an image that is too large, the platform will compress it — often making it look worse. If it is too small, it will appear pixelated or stretched. Getting the dimensions right the first time ensures your content looks professional on every platform. Our free Image Resizer includes all the presets you need to resize images perfectly for any social network, directly in your browser with no uploads required.

Instagram Image Sizes 2026

Instagram has updated its feed layout in recent years, moving from square-only to a mixed format. Here are the current recommended sizes:

• Square feed post: 1080 × 1080 pixels (1:1 ratio)
• Portrait feed post: 1080 × 1350 pixels (4:5 ratio) — this is now the most common format for Instagram feeds
• Story & Reels: 1080 × 1920 pixels (9:16 ratio)
• Profile picture: 320 × 320 pixels (displays as a circle)

For optimal quality, always upload at the highest resolution the platform allows (1080px on the longest side for feeds). Instagram compresses images larger than this, so starting at the right size gives you the most control over the final look.
