Best Aspect Ratio for Every Social Platform (2026)
The same mockup video often needs a different aspect ratio depending on where it's published. Here's the quick reference.
Try Mockly FreeVertical placements (9:16)
Instagram Stories and Reels, TikTok, and YouTube Shorts all use a full-screen 9:16 vertical format — an iPhone frame pairs naturally with this ratio.
Square placements (1:1)
The Instagram and Facebook main feeds, along with many carousel ad formats, work well in 1:1 square, which also suits a no-device frameless composition.
Landscape placements (16:9)
YouTube, LinkedIn video (when not vertical), X, and website embeds generally favor 16:9 landscape, pairing well with Mac or Desktop frames.
Frequently asked questions
Yes, since the underlying aspect ratio differs — set your canvas to the matching ratio in Mockly and re-export for each distinct placement.
1:1 square is the closest to a universal option since most platforms display it without heavy cropping, though it won't fill a full-screen vertical placement like Stories.
Not necessarily, but portrait frames like iPhone and iPad suit vertical ratios more naturally, while Mac and Desktop suit landscape.
