About this portrait US Letter 4-cycle semi-log grid
US Letter is the standard everyday paper size for most home, school, and office printers in the United States and Canada. This template keeps the horizontal X-axis linear with 10mm spacing and uses a base-10 logarithmic scale on the vertical Y-axis.
4 cycles cover four orders of magnitude, for example 1 to 10,000. The plotting area is 195.9 x 259.4 mm, and each logarithmic cycle occupies approximately 64.8 mm.

Why use US Letter 4-cycle semi-log paper?
Four-cycle semi-log paper provides room for wide-range scientific and engineering data spanning four powers of ten.
Exponential growth and decay
Plot population growth, bacterial growth, radioactive decay, cooling curves, and other data where equal ratios matter more than equal differences.
Science and engineering measurements
The 4-cycle logarithmic axis helps spread values across four orders of magnitude, while the other axis remains linear for time, distance, frequency, or another regular variable.
Wide-range plots on US Letter
US Letter is suited to us home, school, and office printing. The page leaves room for titles, axis labels, units, plotted points, and notes around the grid.
US Letter vs A4 4-cycle semi-log paper
Both formats use the same base-10 structure and 4 cycles. Choose US Letter for us home, school, and office printing; choose A4 when international home, school, and office printing better matches the printer or project.

Print US Letter semi-log paper at the correct scale
Use the PDF when accurate spacing matters. The logarithmic subdivisions and stated physical measurements are preserved when the correct paper and scale settings are selected.
- 1
Load US Letter paper
Load 8.5 x 11 inch paper and select Letter as the paper size in the print dialog.
- 2
Use Actual Size
Select Actual Size or 100% scale. Turn off Fit, Shrink, and Scale to Page options.
- 3
Match portrait orientation
Keep the print dialog set to portrait so the graph is not rotated or reduced automatically.
- 4
Check the linear axis
Measure two neighboring lines on the horizontal X-axis; they should be 10mm apart.

FAQ
Answers specific to using and printing 4-cycle semi-log graph paper on US Letter.
What range can 4 cycles represent?
4 cycles span four orders of magnitude. A common example is 1 to 10,000, but the same paper can begin at another power of ten, such as 0.1, 10, or 100.
Which axis is logarithmic on this template?
The vertical Y-axis is logarithmic and the horizontal X-axis uses regular 10mm spacing. Use the custom generator if you need the logarithmic scale on the other axis.
How do I label a semi-log axis?
Assign each major cycle boundary a power of ten that covers your data. Within each cycle, the minor lines represent 2 through 9 times the value at the start of that cycle.
Which print setting keeps the graph true to size?
Select US Letter paper, use Actual Size or 100% scale, and disable Fit to Page. The regular lines on the linear axis should remain 10mm apart.
Should I use portrait or landscape US Letter semi-log paper?
Portrait gives the vertical logarithmic axis more physical room per cycle. Landscape gives the linear horizontal axis more room for time points, labels, and long data series.
