Best Practices for Designing Posts

Selecting the Right Aspect Ratio

• Square: A safe, all-purpose choice great for most photo types.
• Portrait: Best for vertical shots, graphics with text, or designs aimed at maximizing screen space.
• Landscape: Suits broader scenes, cinematic themes, or horizontal compositions.

Keeping Text & Critical Elements in Safe Zones

Because UI elements overlay your content, safe zones are important:

• Stories/Reels: Keep text/icons away from the top and bottom 250px.
• Feed Posts: Allow margin space on the left/right edges to maintain composition balance.

Leveraging Templates and Presets

Using tools like Canva, Figma, or Adobe Express with built-in aspect ratio presets ensures accuracy and speeds up content creation. Templates with safe zone guidelines also prevent accidental cropping of key design elements.
