Square cells, because the stitch really is square
Cross stitch differs from knitting here. On Aida or even-weave, one stitch covers the same distance in both directions, so the chart cell should be square and this one is. Getting that wrong in either direction distorts the design, which is why knitting chart paper is ruled differently even though both are counted crafts worked from a grid.
The heavy line every ten is doing real work
Counted work means counting, and counting past about ten cells without a reference is where mistakes enter. The convention on published charts is a bolder line every ten stitches in both directions, which turns counting into reading off blocks. It also makes it much easier to find your place again after you put the work down, which in practice is most of the time.
Finished size comes from the fabric, not the chart
The chart says how many stitches. The fabric count says how big they are. Divide your stitch count by the fabric count to get inches: 140 stitches on 14-count is exactly 10 inches, on 18-count it is 7.8, and on 11-count it is 12.7. Work that out before you start and add at least three inches in each direction for framing, because that margin is the thing people forget and cannot add afterwards.
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.
