Frequently asked questions
What is aspect ratio?
▾
The proportional relationship between width and height. 16:9 means for every 16 units wide, the frame is 9 units tall. It stays constant regardless of the actual pixel dimensions.
What aspect ratio should I use for social media?
▾
Instagram feed: 1:1 (square) or 4:5 (portrait). Stories and Reels: 9:16. YouTube and most video: 16:9. Twitter/X cards: 16:9. LinkedIn: 1.91:1.
What is the difference between 2.39:1 and 2.35:1?
▾
Both are 'widescreen cinema' formats. 2.35:1 (anamorphic) was the original standard; 2.39:1 is the current DCI standard. The difference is subtle and mostly relevant for film purists.
