Resize for Facebook Post

Facebook feed post images at 1200x630 pixels use a 1.91:1 aspect ratio, which is the same ratio used for Open Graph link previews across the web. This dimension is strategic because it occupies the maximum width of the Facebook News Feed on both desktop (up to 500px rendered width) and mobile (full screen width). Facebook's image processing pipeline re-encodes all uploads as JPEG at approximately 85% quality, and images under 100KB may actually be upscaled slightly, which introduces softness. Uploading at exactly 1200x630 avoids any rescaling.

Facebook's feed algorithm considers image quality as one engagement signal. Blurry, heavily compressed, or text-heavy images may receive reduced distribution. Facebook's automated systems can detect images where text covers more than 20% of the surface area and historically penalized such posts in reach — though enforcement has softened, the best practice remains to keep text minimal. The platform also strips EXIF metadata including color profiles, so always convert to sRGB color space before uploading to prevent color shifts.

The 1200x630 format is landscape-oriented, which presents design challenges on mobile where vertical content occupies more screen space. Despite this, the format remains optimal for link shares and standard photo posts because it provides the widest possible image in the feed. For the best visual impact, use the rule of thirds with the subject positioned at a left or right intersection point. Facebook's feed on mobile displays images at approximately 375 pixels wide by 197 pixels tall, so small details and thin text become illegible.

Common mistakes include uploading images with embedded URLs or watermarks that Facebook's system may flag as low quality, using highly saturated neon colors that shift unpredictably through Facebook's compression, and designing only for desktop view without checking mobile rendering. Another pitfall is using the PNG format for photographic content — Facebook converts it to JPEG anyway, and the larger upload size can cause timeout errors on slow connections without any quality benefit.
