Social Media Image Size Guide

Social platforms can update image requirements, previews, and cropping behavior. Treat this guide as a workflow checklist, then confirm exact dimensions in the official platform documentation before a major campaign.

Start with the intended placement

Common placements include square feed posts, vertical story-style posts, landscape link previews, profile photos, and cover images. Each placement has a different aspect ratio, so it is safer to prepare separate exports instead of forcing one image into every layout.

Keep source files larger than the export

Start from the highest-quality source image you have permission to use. Crop first, resize second, and compress last. This keeps the visible subject under your control before the file is optimized for upload.

Practical SmartCropper workflow

1. Use Square Crop for square feed posts and product thumbnails.
2. Use Circle Crop for profile photos and avatars.
3. Use Custom Crop when a platform needs a specific aspect ratio.
4. Use Custom Scale when you need a smaller or larger export.
5. Use Image Compressor at the end if the file is too large.

What to verify before publishing

• The important subject is not cut off on mobile previews.
• Text remains readable after resizing.
• The file format is accepted by the target platform.
• You have checked the latest platform help page for final dimensions.
