Other spirit level styles include: line levels (single vial with a hook to hand on a string), cross check levels (pocket size; two level vials at right angles), circular levels (surface levels), pocket levels (pen shaped with a magnetic tip) and post levels (wraps around two sides of a post to measure level and plumb). Measure Another option is to rest the level on top of a long or tall straightedge during your measurement. When the bubble is centered between the inside pair, it indicates level.But when it touches one of the outer lines, it means the level is pitched at a 2-percent grade (about inch per foot of run), the slope required for waste lines, sidewalks, and rain gutters to drain properly.
