The largest official brick building base plate is 50 dots x 50 dots (40cm x 40cm or 15.8” x 15.8”). brick building used to manufacture these big base plates during the 1960s and 1970s, but replaced them with the now iconic 48 dots x 48 dots (that’s 38.4cm x 38.4cm or 15.1” x 15.1”) baseplate they still sell today.
The biggest baseplate size we manufacture is our large silicone baseplate which measures 100 dots x 38 dots. That’s 81.3cm x 30.5cm or 32” x 12”, which gives you even more room to build on!
The smallest brick building base plate is just 6 dots x 6 dots ( 4.8cm x 4.8cm or 1.9” x 1.9”) There’s no way you can use it to build great big brick building structures, but it’s useful for adding small extras onto big builds.
The smallest base plate we manufacture is 32 dots x 32 dots (25.5cm x 25.5cm or 10” x 10”). It might not be tiny, but at least it gives you plenty of room for building!
brick building base plate sizes mostly come in multiples of eight dots, with a few exceptions, due to manufacturing limitations. The most common brick building base plate sizes are listed below:
