Event Cover Maker

Mobile crops in noticeably tighter from the sides than desktop does — the safe zone guide above shows roughly 18% cut from each edge on mobile versus 5% on desktop. Text or a logo placed near the left or right edge can look fine on a desktop preview and still get clipped for the majority of guests who see the event on their phone.

At 1200×628, this shares the same aspect ratio as the standard Facebook Post Maker canvas, so a graphic already designed for a feed post can often be reused here directly rather than redesigned from scratch — the main thing worth double-checking is whether any text near the edges survives the tighter event-cover mobile crop, which cuts in further than a typical feed post's own preview usually accounts for.

• •A centered headline that touches the left or right third of the frame is the most common casualty of the mobile crop — nudge it inward rather than trusting the desktop preview alone.
• •Date and time text baked into the image itself is risky here specifically, since the event's real date/time already displays separately below the cover — duplicating it in a corner that gets clipped on mobile adds risk for no real benefit.
