What Is Log Graph Paper?

Log graph paper uses a logarithmic scale instead of the even spacing on a standard grid, so each major division (or "decade") represents a tenfold increase rather than an equal step. The lines within each decade get progressively closer together, matching how values grow logarithmically, which lets you plot numbers spanning several orders of magnitude on a single page without the small values getting crushed against the axis.
