Printable checklist
A blank checklist: a box to tick and a line to write on, repeated down the page. Nothing is filled in, so it works for a shopping list, a pre-flight routine, or a punch list on a building site.

Row height is the only setting that really matters
Nine millimeters is about right for normal adult handwriting with a ballpoint. Go to 11 or 12 mm if you write large, use a fountain pen, or expect other people to fill it in, since strangers always write bigger than you do. Drop to 7 mm only if the items are short, like single grocery words. The failure mode of a tight list is not that it looks cramped, it is that people start writing between the lines and the ticking column stops lining up.
Why a box and a line, rather than just a line
The box does two things a bare line does not. It marks where the item starts, so a list of ragged-length items still reads as a column rather than a ragged block of text. And it gives the eye somewhere to land when you are scanning for what is left, which a page of crossed-out lines cannot do. A column of boxes tells you how far through you are without your having to read a single word.
Ticking, crossing and the case for a bigger box
If you tick, a small box is fine. If you cross items out entirely, or write a code in the box such as a date or an initial, size the box up by raising the row height. The box is drawn as a proportion of the row, so a taller row gives a bigger box automatically. For a list several people sign off, the to-do version with a date field is usually the better starting point.
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.
