Square or portrait?

Use 1080 × 1080 when you want a predictable square that can be reused widely. Choose 1080 × 1350 when the goal is to occupy more vertical space in the feed. The best option depends on the subject: portraits, products and educational steps often benefit from 4:5, while centered quotes and reusable campaign tiles work well in 1:1.

Design for the first second

People encounter a feed post while scrolling. Make the subject and headline understandable immediately. Use a short promise, question or useful statement rather than a paragraph on the artwork. Supporting detail belongs in the caption; the graphic should create recognition and a reason to pause.

Keep the profile grid in mind

A portrait post is shown differently in some previews and profile grids. Keep important words and faces near the center, leave generous margins and preview a square crop mentally before exporting. A safe composition protects the message even when Instagram changes how thumbnails are displayed.

How to make it

1. Select square 1:1 or portrait 4:5.
2. Choose a layout with room for the main subject.
3. Add a concise headline and brand details.
4. Preview at small size and export the final image.

Practical design tips

• Keep headlines short enough for two or three lines.
• Use 4:5 for mobile impact and 1:1 for flexibility.
• Avoid placing critical text against an edge.
• Match the visual promise with the caption.
• Create a reusable draft for recurring series.
