Post Maker

1200×630 isn't specific to Facebook — it's the same size used across the web as the standard Open Graph link-preview image, so a graphic built here will also render correctly if the same URL gets shared on other sites that pull a preview image. That makes this a reasonable default size to reuse beyond just a native Facebook post.

Facebook's own feed truncates a post's text behind "See More" after roughly three lines, so an image with a clear headline baked into the graphic carries more of the message than the caption text underneath it usually does. Since the image is what shows in the feed regardless of whether someone reads the caption at all, it's worth treating the graphic as the primary message rather than a decoration next to the real text.

• •Keep any headline text within the top two-thirds of the frame — Facebook's own preview pipeline can crop image thumbnails slightly differently across surfaces.
• •Lead with color contrast between text and background rather than a busy photo underneath it, since a compressed feed thumbnail loses fine detail fast.
• •Export at the full 1200×630 rather than a smaller version — Facebook recompresses the image regardless, so starting soft only compounds it.
