Common uses
B6 is a compact notebook and book format. ISO B6 and JIS B6 are different sizes, even though both are sold as B6.
How it compares
Two B6 sheets placed side by side make approximately one B5 sheet. Cut B6 across the middle of its long edge to get two B7 sheets. Whole-millimetre rounding can leave a 1 mm difference at a cut edge.
