Frequently Asked Questions
What size should I use for social media?
Choose the format based on where your content will appear. Square and portrait feed posts are useful for feeds, while 9:16 is the common working canvas for full-screen vertical stories and short-form video.
Why does the same size appear on multiple platforms?
Many platforms support similar aspect ratios. Using a common working canvas can simplify content production, but platform-specific publishing requirements can change.
What does aspect ratio mean?
Aspect ratio describes the relationship between width and height, such as 1:1 for a square or 9:16 for a vertical format.
