Using this generator
Semi-log paper has one logarithmic axis and one linear axis. It helps exponential growth, decay, ratios, and data that spans several orders of magnitude become easier to compare on a printed worksheet.

Choose PDF for physical printing and PNG for slides, worksheets, or digital notes.
Common questions
Answers about choosing settings, using the preview, and exporting this paper type.
Choose the axis for the variable that changes by ratios or spans orders of magnitude. Keep the other axis linear for evenly spaced values such as time or distance.
Use enough cycles to cover the full numeric range of the logarithmic variable. Two cycles cover two powers of the selected base, three cycles cover three powers, and four cycles cover four powers.
Base 10 is standard for scientific and engineering plots. Choose another base only when the calculation or course specifically uses it.
Each template has a crawlable image URL and a direct PDF URL, so it can be linked, indexed, and shared without running the generator.
