One log axis
Use semi-log paper when values change by powers of ten but one axis still needs normal linear spacing.
Printable Semi-Log Paper PDFs
Semi-log paper uses one logarithmic axis and one linear axis, which makes exponential growth, decay, frequency response, and lab measurements easier to read.

Semi-log paper FAQ
What can I draw on semi-log paper?
Semi-log paper is used for exponential growth, decay curves, Bode plots, frequency response, bacterial growth, population change, half-life, and measurements spanning powers of ten.
Which semi-log cycle count should I print?
Use 1-cycle for one decade of values, 2-cycle for two decades, and 3-cycle when the data spans three orders of magnitude.
Can I download A4 semi-log paper?
Yes. Filter by A4 or open a semi-log template to download A4 semi-log graph paper as a PDF or PNG.
