TikTok Slideshow Size & Dimensions
The recommended TikTok slideshow size is 1080×1920 pixels — a 9:16 vertical ratio that fills the screen. Keep important text away from the edges so UI elements don’t cover it.
Getting the dimensions right is the difference between a crisp, full-screen slideshow and one that’s cropped or letterboxed. Here’s the size to use and how to keep your content in the safe zone.
The right size
Use 1080×1920 pixels (9:16). That’s the native full-screen vertical format on TikTok, so your slides fill the screen with no black bars.
Safe zones
TikTok overlays the caption, username, and action buttons along the bottom and right. Keep your hook and key text centered and away from those edges so nothing important gets covered.
Get it right automatically
ViralSlides renders every slide at 1080×1920 with safe margins built in, so you never have to think about cropping.
FAQ
What aspect ratio is a TikTok slideshow?
9:16 (vertical), which is 1080×1920 pixels at the recommended resolution.
Can I use square images?
You can, but they’ll be letterboxed. Vertical 9:16 fills the screen and performs better.
