Every platform sizes posts, stories, covers and avatars differently; the wrong ratio means awkward padding at best and cropped-off subjects at worst. Checking the correct size before you design saves the 'oops, it cut off the head' redo and keeps your visuals consistent and professional.
Keep key text and faces in the central safe zone so platform UI (buttons, avatars, gradients) doesn't cover them; vertical 9:16 suits stories and short video, while 1:1 and 4:5 take up feed space without being cropped. Understanding ratios beats memorising every number.
One key visual often goes to several platforms — design at the largest size first, then crop and scale down to each version so quality doesn't suffer from upscaling. Afterwards, shrink files with our image compressor so they upload faster and survive the platform's own re-compression.
We periodically check each platform's official specs and update. If you spot a change, let us know.
Pair it with our image compressor and resize tools to build to the recommended pixels.
Most platforms recommend JPG or PNG. Use PNG for crisp covers and JPG for smaller photo files.
