Cut out each strip along its outline. Lay the end of strip 1 on the tab at the top of strip 2 so the numbers run on, and tape it; carry on to the last strip. Paper stretches very little, but a fold or a gap at a joint makes the tape read long, so keep each joint flat and butted up to the line.
Choose Actual size or 100% in the print dialog. Measure the 100 mm check line with a ruler you trust before using the tape. If it is not 100 mm, change the print settings and print again.
