48x48 Baseplates

The 15” x 15” (48 dot x 48 dot / 38cm x 38cm) LEGO baseplates are the largest baseplates produced by LEGO today.
In the 1960s and 1970s, LEGO produced slightly larger baseplates (50 dots x 50 dots) but these were discontinued when the company began producing baseplates which are almost exclusively in multiples of 8 dots, this allows manufacturing costs to be kept down.
