TikTok vs Reels vs Shorts: the format differences that matter

All three platforms want vertical short-form video, but the details differ enough to trip you up. Here is a quick rundown.

Aspect ratio

All three use a 9:16 vertical frame. Keep important content away from the edges, where each app overlays its own UI.

Length

Maximum lengths drift over time and differ per platform. Aim for the shortest version that tells your story so the same cut works everywhere.

Captions and safe zones

Each platform places buttons and captions in slightly different spots. Keep text and faces within the central safe zone so nothing is covered.
