Aspect ratio preview
One image, every network's frame, side by side. Find out what gets cut off before you post it rather than afterwards.
Keeping the important part
Crops are taken from the centre, so anything near an edge is what disappears first. If a face, a logo or a caption sits close to the frame, move it inward before you export — no scheduler can recover what the network trimmed.
Questions
Why does my image get cropped at all?+
Because each network renders media at its own shape — 9:16 on TikTok, square on an Instagram feed post, 16:9 on YouTube, 2:3 on Pinterest. Anything that is not already that shape gets trimmed to fit, and what gets trimmed is the edges.
Which shape should I shoot for?+
If short-form video is most of what you make, shoot 9:16 and let the landscape networks letterbox — the loss is smaller in that direction. If you are posting one image everywhere, square survives the most crops with the least damage.
Does this match what Eurekuh actually publishes?+
Yes — the shapes here come from the same table the composer's preview uses, so the tool and the product cannot disagree.
