Portrait Posts (1080 × 1350 px)
Portrait posts continue to perform well because they occupy more screen space in users’ feeds, making them more noticeable while scrolling.
Square Posts (1080 × 1080 px)
Square images remain a popular choice for product showcases, quotes, and branded graphics.
Landscape Posts (1080 × 566 px)
Landscape images are suitable for wide shots and panoramic photography but generally receive less screen space than portrait posts.
Stories and Reels (1080 × 1920 px)
Vertical content continues to dominate Instagram. The full-screen 9:16 format provides an immersive experience, making it perfect for tutorials, behind-the-scenes videos, product launches, and promotional content.
Carousel Posts
Using portrait-sized slides (1080 × 1350 px) allows each image to occupy more space in the feed. Carousels are ideal for educational content, step-by-step guides, case studies, and storytelling.

- Design with mobile users in mind.
- Keep important text and logos away from the edges.

Following these practices helps your posts look more professional and encourages higher engagement.
