Engineering Graph Paper, 4 per Inch, Letter
Four divisions per inch with a heavy line every fourth cell places majors exactly one inch apart, a pitch many engineering homework sheets list alongside the ANSI five-per-inch standard. Drafters and EE students who need slightly coarser cells than ten per inch use this spacing when the brief names four squares per inch.
