Instagram Feed Square (1080×1080)
The square format is Instagram's most versatile and popular ad size. It displays consistently across both mobile and desktop, making it ideal for product photography, lifestyle content, and brand awareness campaigns. Square posts take up more vertical space in the feed, increasing visibility and engagement rates.
Specifications:
- Recommended size: 1080 × 1080 pixels
- Aspect ratio: 1:1 (square)
- Supported formats: JPG or PNG
- Maximum file size: 30 MB
Best Practices:
- Use high-quality, vibrant images that stand out in the feed
- Keep important elements centered to avoid edge cropping on different devices
- Test different product angles and lifestyle contexts
Instagram Story & Reels Ads (1080×1920)
Instagram Stories and Reels ads are full-screen vertical formats that capture maximum attention. Stories appear between users' organic stories, while Reels ads show up in the Reels feed. With over 500 million daily Story users and Reels being Instagram's fastest-growing feature, these formats are essential for reaching younger audiences and driving engagement.
Specifications:
- Recommended size: 1080 × 1920 pixels
- Aspect ratio: 9:16 (vertical)
- Safe zone: Keep critical content 250px from top and bottom
Best Practices:
- Design for mobile-first with bold, easy-to-read text
- Use motion, animation, or quick cuts to capture attention in first 3 seconds
- Include interactive elements like polls or swipe-up CTAs
Instagram Feed Vertical (1080×1350)
The 4:5 vertical format is optimized for maximum screen real estate on mobile devices. It takes up approximately 30% more screen space than square posts, increasing visibility in the feed. This format is perfect for showcasing products, people, or content where you want to maximize vertical space without committing to full-screen Stories.
Specifications:
- Recommended size: 1080 × 1350 pixels
- Aspect ratio: 4:5 (portrait)
