  <p>It's only slightly larger than a 48x48, and it's a bit more difficult to use in large setups since most other common baseplates have side lengths that are a multiple of 16, so you might actually be better off with a 48x48 depending on what you are trying to do.</p>

Body: <p>I'm looking for as large a base plate as possible. Below is a 48x48 stud base, it's the largest I've seen.</p>
  
  <p>Are larger plates available? Either the thin type (as pictured) or the regular plate thickness will do!</p>
