The Golden Spec

According to [Buffer](https://buffer.com/resources/social-media-image-sizes/) and [SocialBee](https://socialbee.com/blog/how-to-make-a-slideshow-on-tiktok/), 1080×1920px at 9:16 is the universal standard for TikTok slideshows, stories, and reels. Using this exact size prevents pixelation and blurry visuals that drive users away.

Pixels — the required TikTok slideshow size

9:16 aspect ratio, full vertical screen fill

Pro tip: Keep all critical visuals and text centered in the middle zone of the frame. TikTok's UI overlays (captions, buttons, username) eat into top and bottom edges.
