The vertical video wars are over and everybody won the same trophy. Tiktok video dimensions are 1080 by 1920, nine sixteen, same as Reels, same as Shorts. The dimensions question is settled. Length is where it gets interesting.
TikTok has stretched its maximum length several times, and the current cap is generous compared to the old days. But longer is not better. The algorithm famously rewards watch time and completion rate, and a tight 30 seconds beats a rambling three minutes for most creators. Edit ruthlessly. The creators who treat length as a budget, not a target, win.
The tiktok video max file size and length limits are worth knowing but almost never bite. Unless you're uploading enormous high-bitrate files, you'll never notice them. What actually gets videos rejected: odd aspect ratios and burned-in black bars. Film vertical, export vertical, done. It's genuinely that simple.
Repurposing is where these dimensions really pay off. One vertical export serves TikTok, Reels, and Shorts. The only real adjustments are captions, hashtags, and posting times. Film once, publish three times, spend the saved hours on the next idea. At volume, an auto format content for social media app kills the manual exporting entirely. One master in, correct versions out. Teams running a real content repurposing SaaS pipeline go further and automate the scheduling too, so the same video hits every platform the same day.
One more thing: safe zones. The right side has the like and comment buttons, the bottom has the caption. Keep the subject centered and text clear of the edges. Same discipline as Reels. Your future self will thank you when the video starts performing.
