Is porcelain better than a melamine whiteboard?

Yes for heavy use. Porcelain-on-steel resists ghosting, staining and scratching far better than melamine, which tends to absorb marker over time. The trade-off is weight and a higher upfront cost.

Does it hold magnets?

Yes. The steel core makes the surface magnetic, so magnets hold notes, printed pages and markers.

How big is it, really?

The board is 60 inches tall and 144 inches wide, so 5 by 12 feet. Check the wall space and door clearances before mounting it.

How should it be mounted?

It is a large, heavy board, so it should be fixed to wall studs or a solid backing rather than drywall anchors alone. A two-person install is sensible.

What markers work on it?

Standard dry-erase markers work. Use a dry-erase eraser and clean the surface periodically with a whiteboard cleaner to keep it writing cleanly.

Rooms where the board is used daily and by several people: conference rooms, classrooms and long shared work areas. A lighter melamine board is enough for occasional home use.
