SNS Image Size
The recommended image dimensions and aspect ratios for each social media platform, ensuring optimal display without unwanted cropping or recompression.
SNS image size refers to the pixel dimensions each social platform recommends for optimal display in feeds and profiles. Uploading images outside these specifications triggers automatic cropping or recompression, potentially ruining composition or degrading quality.
Key recommended sizes (as of 2025): X (formerly Twitter) timeline images at 1200×675 px (16:9), Instagram feed at 1080×1080 px (1:1) or 1080×1350 px (4:5), and Facebook share images at 1200×630 px. OGP (Open Graph Protocol) images at 1200×630 px serve as a universal size compatible with most platforms.
The SNS resize tool automatically adjusts aspect ratio and dimensions to match your selected platform. This simple step before posting significantly improves how your images appear in feeds.
