When it makes sense
Its main advantage is portability. Half Letter pages are easier to flip through, punch, file, and carry. They work especially well when the content is short-form: task lists, weekly planning, reading notes, check-ins, and reference inserts.
What to watch next
The tradeoff is writing area. If you routinely take long lecture notes or full meeting minutes, Letter or A4 is still easier. Half Letter wins when the page should be compact by design, not merely reduced after printing.
Printing tips
Print on Letter only if the PDF is laid out for 2-up output or for a trim workflow you actually control. Otherwise, a Half Letter design can drift when margins, duplex alignment, or booklet settings are applied automatically.
