Semi-log paper keeps one axis linear and spaces the other axis by powers of ten. This makes curved exponential data appear closer to a straight line, which is useful when comparing growth rates, decay curves, lab measurements, and engineering responses.
Customize a Semi-Log GraphMatch the number of logarithmic cycles to the range of your data.
Use the PDF file for sharp printouts with clean grid lines.
Select Actual Size in the print dialog to preserve spacing.
Short answers for the common semi-log paper questions people usually have before printing.
Semi-log graph paper is used when one value changes exponentially while the other changes linearly. It is common in science labs, engineering measurements, population growth, radioactive decay, and frequency response work.
Use the 1-cycle template for a compact range, 2-cycle for medium-range data, and 3-cycle when values span several orders of magnitude. The A4 portrait 3-cycle template is the safest general-purpose choice.
Print the PDF at Actual Size or 100% scale. Avoid Fit to Page if you need accurate spacing for measurement or lab work.
