Three-point perspective grid
Two vanishing points on the horizon plus a third far below, for looking up at a tall building or down from a height.

The third point handles verticals
In one- and two-point perspective, verticals stay vertical — a convention that works because at normal eye level the convergence is too slight to notice. Look sharply up or down and it becomes obvious: the sides of a skyscraper visibly lean together. The third vanishing point, placed far above or below the frame, captures that.
Worm's-eye and bird's-eye
A third point below the page makes verticals converge downward and the subject towers over the viewer — the classic superhero or skyscraper shot. A third point above does the opposite and the viewer looks down from height. The choice reads as emotional before it reads as geometric, which is why comics and film storyboards use it so heavily.
Keep the ray density low
Three sets of converging lines cover a page quickly and can become impossible to draw over. Raise the ray interval so the grid is sparse — you only need enough guides to establish the convergence, and your eye will interpolate the rest. Anything denser fights the drawing.
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.
