Printable semi-log templates
These poster portrait 10mm 4-cycle semi-log graph paper templates are ready for printing. Download the PDF, save a PNG preview, or open the generator to adjust cycles, spacing, and labels.
These filters use the same parameter URL format as the original semi-log pages. Grid spacing defaults to 10mm; only curated combinations are indexed.
1 printable templates across seven paper sizes, each available in portrait and landscape with direct PDF and PNG downloads.
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.
Choose A4 or Letter for common printers, A3 or A2 for larger plots, and Legal, Tabloid, or Poster for specialized formats. Every file on this page spans four logarithmic cycles and is available in portrait and landscape.
Print the PDF at Actual Size or 100% scale. Avoid Fit to Page if you need accurate spacing for measurement or lab work.
Four logarithmic cycles cover four orders of magnitude, such as 1 to 10,000, 10 to 100,000, or any equivalent four-decade range.
