Exact dimensions

How big is that in real life?

  • Roughly the size of an adult hand with fingers stretched, just a bit taller and wider.
  • It is half the size of standard A4: if you cut an A4 sheet in half across the longer side, you get two A5 sheets.

  • Common for small notebooks, journals, planners, and flyers.
  • Handy when you want something more compact than A4 but still clearly readable for text and graphics.
