Monday start is the international standard
ISO 8601 defines Monday as the first day of the week, and that is what calendars, timetables and business planning use across Europe and most of the world. This sheet starts Monday for that reason. The United States, Canada and Japan commonly start on Sunday instead, which is why there is a Sunday start version. Neither is wrong; they are just different conventions, and mixing them up costs you a day.
A4 files with everything else
If your work papers, printed timetables and binder are A4, a Letter planner sits proud of them and catches at the edges. Matching the size sounds trivial and is the difference between a planner that lives in the binder and one that ends up loose on a desk. Switch on the two-hole ISO 838 punch guides and it will file in any standard European binder.
Weekend blocks the same size as weekdays
Many commercial planners shrink Saturday and Sunday into a single block, on the assumption that nothing happens then. If that suits you, turn the weekend off entirely and use the five-day sheet. If it does not, this gives all seven days equal room, which is the more useful default for anyone whose weekends are as busy as their weeks.
Printing it accurately
This only measures correctly if your printer doesn't rescale the page. In the print dialog set Scale: 100%, not "Fit to page" or "Shrink oversized pages". If you're not sure it worked, print the calibration page, measure the ruler on it with a real ruler, and it will tell you exactly what your printer is doing to the page.
