Whats The Smallest Big Block?

There is no definitive answer to this question as it depends on a number of factors, including the intended use of the big block. For example, if the big block is intended for use in a construction project, then the smallest size would be dictated by the dimensions of the project. However, if the big block is intended for use as a decorative item or piece of furniture, then it could be any size that is deemed suitable. In general terms though, a small big block would typically measure between 1 and 2 feet in width and length, with a height of around 6 inches.
