Monthly printable calendar: one month, one sheet, sized to be written on

The generator below is in month layout and opened on the current month. Change the month, the paper and what appears on the grid, then print or take the PDF. This page is about the layout itself — what it is good at, exactly how big the boxes are, and the two cases where a different sheet is the right answer.

The scenario this layout is for

One month per sheet is the calendar you write on. It goes on a fridge, a noticeboard, a desk or inside a binder, and its unit is the day: appointments without times, deadlines, shifts, bin days, homework, medication, holidays booked. It is the only common layout where a whole day’s worth of handwriting fits in the space allotted to that day, which is why it is the default here and why every month page on this site uses it.

It is also the layout that survives being printed once and used for four weeks. A week planner has to be reprinted every seven days and a year sheet is a reference rather than a surface, so a monthly sheet is the only one of the three with a printing cost that matches how long people keep it.

The geometry, in numbers

Seven columns, one per weekday, and five or six rows depending on the month and the week start. On portrait US Letter with a half-inch margin, a five-row grid gives each day box roughly 1.7 inches of height and a little over an inch of width — the printable width is 7.5 inches shared by seven columns. A six-row month takes the height down to about 1.4 inches while the width is unchanged, because the extra row comes out of the same fixed sheet. Landscape reverses the shape: wider boxes, less height, which suits a month with long holiday labels or several words per day.

Two optional columns change the arithmetic. Switching ISO week numbers on adds a narrow eighth column at the left, roughly two and a half percent of the sheet width, which the seven day columns give up between them. Switching the notes column on is a bigger change: it takes 22 percent of the body width off the right-hand side, so every day box loses roughly a fifth of its width. That is a real trade and worth making deliberately — the notes layout page works through when it pays.

Row count is per month, and this site prints it

The most useful number for a monthly sheet is the one nobody publishes: how many week rows this particular month needs. It is not a property of the month name. It depends on the weekday the 1st falls on and on where you start the week, so the same month can need five rows with a Sunday start and six with a Saturday start, and a 28-day February that begins exactly on your week-start day fills four rows and borrows nothing from either neighbour. Every month page here states its own answer, and both year hubs carry a twelve-row comparison table.

When a different sheet is the right answer

• You need times, not dates. A day box has no internal structure. If you are scheduling appointments to the hour, the weekly layout with its time rail is the correct tool and a monthly sheet is a compromise.
• You need to see the year at once. Counting a twelve-week lead time or checking which weekday a date in August falls on is a reference task, and flipping through twelve sheets is the slow way to do it. Print the whole year on one page instead.
• You are printing a set with mixed row counts. A six-row month and a five-row month printed together have visibly different box heights. Either pick a week start that gives the whole run the same count, or accept it knowingly.

Whichever you print, the settings that decide whether it comes out the right size are the same four: paper, scale, margins and your browser’s headers. The printing guide covers all four.
