Blank chord chart paper
A page of empty chord boxes — six strings, adjustable fret count, a thick nut across the top and a line above each for the chord name.

Reading a chord diagram
The six vertical lines are the strings, lowest-pitched on the left. The horizontal lines are frets, and the thick line at the top is the nut. Dots mark where fingers go; an X above a string means do not play it, an O means play it open. If the shape is further up the neck, the nut is drawn as a normal line and a fret number is written beside the diagram.
How many frets to show
Four or five frets covers almost every common shape, since the hand only spans about four frets comfortably. Choose more only if you are notating wide stretches or want room to mark several positions of the same chord. Fewer boxes at a larger size is usually more useful than many tiny ones.
What the sheets are for
Teachers use them to write out a lesson's chords on one page. Songwriters use them to record shapes they have found before forgetting them — which happens faster than anyone expects. Keeping a chord vocabulary on paper rather than in an app also means it works on a music stand without a screen timing out.
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.
