Leuchtturm1917 Sizes

Leuchtturm1917’s notebooks and planners generally follow standard ISO paper sizes, but they do use some variants, like A4+ and B6+. Here are the sizes, from smallest to largest…

  • Mini: A7 size (70 x 110 mm)

  • Medium: A5 size (145 x 210 mm)
  • Composition: B5 size (178 x 254 mm)

Of these, the Medium (A5) is the main size sold in the US, thanks in part because when it’s open it’s exactly the size of an A4 sheet of copy paper. The B5 size is also quite popular and gives writer a bit more room to spread out.
