Frequently asked questions
What is the exact Facebook cover size?
851×315 pixels for pages (displays at 820×312 with slight rounding), 1640×856 for groups, 1200×628 for events. Uploading larger just triggers Facebook's crop UI.
How do I make my cover look good on both desktop and mobile?
Treat it as two compositions: the full 851×315 for desktop, with a centered ~640×315 safe zone that stands alone for mobile. Text at the far left/right edges disappears on phones.
Why does Facebook make my cover blurry?
Its recompression is brutal on gradients and fine text. Use a high-quality source at exact dimensions, avoid ultra-fine fonts, and prefer solid-color bands over subtle gradients.
