Common Instagram Post Mistakes

Forcing Vertical Images into Squares

Trying to fit tall vertical images into square format often cuts off important elements. Use our resizer's letterboxing instead.

Ignoring Grid Aesthetics

Random post formats and styles make profiles look disorganized. Maintain consistency with square 1:1 posts.

Poor Image Quality

Low-resolution or poorly lit images look especially bad in Instagram's square format. Always start with high-quality source material.

Off-Center Subjects

Important elements placed at extreme edges may not display well in all Instagram contexts (like the Explore page).
