C2C is the crochet that wants square paper
Ordinary crochet chart paper uses cells taller than they are wide, because crochet stitches are. Corner-to-corner is the exception. You build the fabric from small square blocks worked diagonally, and one chart cell is one block rather than one stitch. The blocks come out close to square, so the chart should be square too. Using tall-celled crochet paper for a C2C graph will distort the design.
One cell is a tile, not a stitch
This is the thing to hold onto when reading a C2C chart. Each square tells you the color of one whole block, and each block is several stitches worked as a unit. That is also why C2C suits pixel-art style designs so well: the tile is already a pixel, and the diagonal construction means you are effectively filling in a bitmap.
Work the diagonal, and mind the corner
C2C graphs are usually worked from the bottom-right corner up to the top-left, in diagonal rows rather than horizontal ones. Mark your starting corner on the chart before you begin, because a graph read from the wrong corner produces a mirrored blanket and you will not notice until it is too large to want to undo. Count the diagonal rows too, since the increase and decrease points are what keep the rectangle square.
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.
