A5 Copy Papers
Halving the sheet is the obvious economy for order slips, notices and half-page handouts, and the reason it goes wrong is the machine rather than the paper. Many trays have a minimum length and will misfeed or skew A5, and manual bypass trays vary. Run a test ream before committing. Weight follows the same logic as A4.
