Adjust Seyes dimensions and colors
Switch from the standard 2 mm + 8 mm Seyes layout to the enlarged 3 mm / 12 mm version.
Use the millimeter SVG preview, then print or save to PDF.

Usage tips
Print at 100% (actual size). Turn on the 50 mm calibration box to verify the scale.
Standard Seyes uses 2 mm / 8 mm, while the enlarged 3 mm / 12 mm layout helps beginners.
Share copies a URL with the settings to reuse the layout for handouts.
How to use this tool effectively
This guide helps you use Seyes (French ruled) paper PDF generator in a repeatable way: define a baseline, change one variable at a time, and interpret outputs with explicit assumptions before you share or act on results.
How it works
The page applies deterministic logic to your inputs and shows rounded output for readability. Treat it as a comparison workflow: run one baseline case, adjust a single parameter, and measure both absolute and percentage deltas. If a result seems off, verify units, time basis, and sign conventions before drawing conclusions. This approach keeps your analysis reproducible across teammates and sessions.
When to use
Use this page when you need a fast estimate, a classroom check, or a practical what-if comparison. It works best for planning and prioritization steps where you need direction and magnitude quickly before investing in deeper modeling, manual spreadsheets, or formal external review.
Common mistakes to avoid
- Changing multiple parameters at once, which hides the true cause of output movement.
- Mixing units (percent vs decimal, monthly vs yearly, gross vs net) across scenarios.
- Comparing with another tool without aligning defaults, constants, and rounding rules.
- Using rounded display values as exact downstream inputs without re-checking precision.
Interpretation and worked example
Run a baseline scenario and keep that result visible. Next, modify one assumption to reflect your realistic alternative and compare direction plus size of change. If the direction matches your domain expectation and the size is plausible, your setup is usually coherent. If not, check hidden defaults, boundary conditions, and interpretation notes before deciding which scenario to adopt.

FAQ
Can I change the Seyes dimensions?
Yes. Adjust the minor and major spacing, and choose whether the vertical lines match the majors or use a custom spacing.
Can I hide the margin line?
Yes. Turn off the margin line if you do not need it. For note-taking, keeping it on is recommended.
Is there a scan-friendly color option?
Yes. The scan-friendly gray preset keeps lines faint for submissions or scanning.
What should I do first on this page?
Start with the minimum required inputs or the first action shown near the primary button. Keep optional settings at defaults for a baseline run, then change one setting at a time so you can explain what caused each output change.
Why does this page differ from another tool?
Different pages often use different defaults, units, rounding rules, or assumptions. Align those settings before comparing outputs. If differences remain, compare each intermediate step rather than only the final number.
