Why Aspect Ratio Matters
Using the wrong aspect ratio means your images get cropped awkwardly by social media platforms, cutting off important parts of your photo. By cropping to the correct ratio beforehand, you control exactly what viewers see.
✅ Do This
Crop to platform's preferred ratio before uploading. Your image displays exactly as intended.
❌ Avoid This
Uploading without cropping. The platform auto-crops, often cutting off heads, text, or important details.
