Optimize Creative for Feed and Explore Placements
Feed and Explore ads reward clarity and relevance, so your images and videos must adapt to multiple screen sizes without losing impact. Use 1:1 for photos and 4:5 for video to maximize attention and minimize cropping surprises.
For Explore placements, prioritize a 16:9 landscape format to take advantage of wider displays and ensure your key message remains visible. Testing multiple sizes in the same campaign helps you identify which format drives stronger engagement for your audience.
Key image specifications for feed ads
Minimum dimensions and file requirements matter because they protect your creative from distortion. For static image ads, keep your files under 30 MB and choose at least 1080 pixels on the longest side to maintain sharpness on high-density screens.
Designing High-Impact Stories and Reels
Stories and Reels are prime real estate for bold, vertical content, making 9:16 the go-to Instagram ad size for this placement. Full-screen vertical ads capture attention in moments when users are most engaged, increasing the likelihood of views and interactions.
When designing for Reels, consider adding text captions and brand-safe colors so your message remains clear even when sound is off. Consistent use of this size across campaigns builds a recognizable visual rhythm for your audience.
Best practices for vertical video
Keep critical elements within the central area of the frame to avoid being obscured by UI elements like buttons or headers. Aim for 1080 x 1920 pixels and use clean, high-contrast visuals to ensure readability on smaller mobile devices.
Leveraging Carousel and Collection Ads
Carousel and Collection ads rely on a 1:1 square format, which provides a consistent canvas across multiple cards. This Instagram ad size works especially well for product catalogs, step-by-step guides, and brand storytelling that benefits from sequential slides.
By maintaining a uniform aspect ratio, you simplify the creative process and ensure a cohesive look across the entire series. Pair strong visuals with concise copy to guide users through each card in the journey.
