Why Video Shape Matters
A video's aspect ratio is just its shape. The two most important shapes today are:
Widescreen (16:9): A long rectangle, perfect for TVs and YouTube.
Vertical (9:16): A tall rectangle, perfect for phones and apps like TikTok.
Choosing the right shape ensures your video fills the screen and looks great. If you need to figure out the exact pixel size for a video, our video ratio calculator can help.
