Frequently asked questions
What is the best image size for X (Twitter)?
For feed posts, upload 1600×900 (16:9) — the format X (Twitter) renders without cropping. SocialRoute previews your visual at exactly these dimensions before you publish.
What happens if my image is the wrong ratio?
The platform center-crops your image to its nearest supported ratio, which can cut off faces or text. SocialRoute flags mismatched ratios and shows the exact crop for every platform you've selected, before you publish.
Can I use the same image on every platform?
You can, but each platform crops differently — a square that looks great on Instagram loses its edges on X. SocialRoute takes one visual and previews it at every selected platform's native dimensions so you catch bad crops early.
