Aspect ratios and file/length limits reflect what PersonaXpand enforces when publishing to each platform. Recommended pixel sizes are the standard resolution for each accepted ratio and are approximate — platforms occasionally adjust their specs.

One upload, every size — handled for you

Every platform wants a different shape: a 4:5 portrait shines in the Instagram feed, a 1.91:1 landscape fits a Facebook link, and stories and reels need a full 9:16. Resizing by hand for each is tedious and easy to get wrong. When you publish with PersonaXpand, your images and video are automatically conformed to each platform’s accepted ratios and limits — upload once, and it’s correct everywhere.

Writing a caption too? Check it against every limit with the social media character counter or the full character-limits table.

Image size FAQs

What are the recommended image sizes for social media in 2026?

Square posts are 1080 × 1080 px (1:1), portrait is 1080 × 1350 px (4:5), landscape/link images are 1200 × 628 px (1.91:1), and vertical stories and reels are 1080 × 1920 px (9:16). The table above lists which ratios each platform accepts.

What is the best aspect ratio for Instagram?

Instagram accepts 1:1, 4:5, 1.91:1 and 9:16. For the feed, 4:5 portrait (1080 × 1350 px) takes the most screen space; for reels and stories use 9:16 (1080 × 1920 px).

What size should a vertical story or reel be?

9:16, at 1080 × 1920 px. Keep important text and faces inside the central safe area so the platform's UI doesn't cover them.

Will PersonaXpand resize my images for each platform?

Yes. When you publish, PersonaXpand automatically conforms your images and video to each platform's accepted aspect ratios and size limits, so one upload works everywhere.
