Choose an image and the fit report for every major platform appears here, with a crop preview for each placement.
- 1Choose or drop the image you plan to post.
- 2Read your image's real dimensions at the top.
- 3Go platform by platform: check the verdict and look at the crop preview for the placements you will actually use.
- 4Export the image at the sizes marked too small or badly cropped, using your usual image editor or our Image Resizer.
A 1600 x 900 image is an exact match for the X post image (1600 x 900). For the Facebook shared image (1200 x 630) it has enough pixels but a different shape, so it reports 'Will be cropped'. For the YouTube banner (2560 x 1440) it is the same shape but smaller, so it reports 'Too small', and the same verdict applies to a 1080 x 1920 story slot, where it is also short on height.
- Recommended sizes are a snapshot of platform guidance dated November 2026. Platforms revise them, and a slightly older size usually still displays fine.
- Verdicts use a 2 percent shape tolerance: within that, scaling is treated as a clean fit rather than a crop.
- The checker judges dimensions only. It cannot tell you whether faces or text sit inside a platform's safe zones, so keep important content away from edges for stories and banners.
Your image has enough pixels, but its width-to-height shape differs from the placement, so the platform trims the overflow. The preview box shows the framing you would get.
