In more detail
Short-form video grew out of how people actually scroll: fast, vertical, and sound-optional. Clips run from a few seconds up to about 3 minutes, but the sweet spot is 15 to 60 seconds. The format rewards a strong first second (the hook), captions for sound-off viewing, and one clear idea per clip. Platforms push it hard because it keeps people watching, so it is often the cheapest way for a small account to reach new people who do not follow you yet.
Example
A coffee shop films a 20-second clip of a latte being poured, adds a one-line caption and a trending sound, and posts it as a Reel and a TikTok. It reaches 12,000 people, most of whom had never seen the shop before, because the platform showed it to non-followers who watched similar videos.
FAQ
Short-form video, answered.
How long should a short-form video be?
Most perform best between 15 and 60 seconds. Hook viewers in the first second or two, since that is when most people decide to keep watching or scroll past.
Is short-form video the same across TikTok, Reels, and Shorts?
The format is similar (vertical, short, sound-on), but each platform favors slightly different lengths, trends, and editing styles. The same clip often works on all three with minor tweaks to captions and sounds.
