How to use logarithmic graph paper

A logarithmic scale makes multiplicative changes easier to compare. Choose this layout when positive values span several orders of magnitude.

Enlarged logarithmic grid excerpt with blue marks labeled 1, 2, 5 and 10
Example in use. The labeled positions within one decade are unevenly spaced: equal distance on a log scale represents a ratio.This is a usage illustration. Customize the sheet above before downloading.
  1. Assign values to the decades

    Decide whether successive decade bands represent 1–10, 10–100 or another positive range. Label the logarithmic axis before plotting.

  2. Place values using the minor divisions

    Locate a value within its decade rather than counting every line as an equal numerical step. Use the ordinary axis for the other quantity.

  3. Read changes as ratios

    Compare multiplication, such as a change from 1 to 10 and from 10 to 100. Confirm the axis labels when interpreting a slope.

Try this. Zero and negative values cannot be placed on an ordinary logarithmic scale. Use a linear grid when those values are part of the exercise.
