Common Inquiries

Frequently Asked Questions

Dimension guidelines.

What are the standard dimension layouts included?

The tool supports high-definition social dimensions:

  • YouTube: Thumbnail (1280x720) & Channel Banner (2560x1440)
  • Instagram: Square Post (1080x1080), Story/Reel (1080x1920), & Portrait (1080x1350)
  • Twitter / X: Post Image (1200x675) & Header Banner (1500x500)
  • Facebook: Cover Photo (820x312) & Post Image (1200x630)
What is the difference between 'Fit' and 'Fill'?

Fill scales the image up so that it completely covers the target aspect box (cropping excess parts). Fit scales the image down so that the entire picture is visible, adding transparent or solid borders to fill empty margins.
