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.
