Adjust Tianzige/Mizhige for your practice
Switch between Tianzige (cross) and Mizhige (cross + diagonals), and tune bold lines and opacity.

Usage tips
Print at 100% (actual size). Turn on the 50 mm calibration box to verify the scale.
Tianzige uses only the center cross; Mizhige adds diagonals. Choose based on your practice goals.

How to use this calculator effectively
This guide helps you use Chinese character grid PDF generator (Tianzige / Mizhige) in a repeatable way: define a baseline, change one variable at a time, and explain each output using explicit assumptions before sharing results.
How it works
The calculator applies deterministic formulas to your input values and only rounds at the final display layer. This makes it useful for comparative analysis: keep one scenario as a baseline, then vary assumptions and measure the delta in both absolute terms and percentage terms. If a change appears too large or too small, verify units, period conventions, and sign direction before interpreting the result.
When to use
Use this page when you need a fast planning estimate, a classroom check, or a reproducible scenario that teammates can review. It is most effective at the decision-prep stage, where you need to compare options quickly and decide which assumptions deserve deeper modeling or external validation.
Common mistakes to avoid
- Mixing units such as percent vs decimal, or monthly vs yearly settings.
- Changing multiple fields at once, which hides the real cause of result movement.
- Comparing outputs across tools without aligning constants and default conventions.
- Treating rounded display values as exact inputs for downstream calculations.
Interpretation and worked example
Start with a baseline case and save that output. Next, edit one assumption to reflect your realistic alternative, then compare both the direction and size of change. If the direction matches domain intuition and magnitude is plausible, your setup is likely coherent. If not, check hidden defaults, unit conversions, boundary conditions, and date logic before drawing conclusions.

FAQ
Which should I use, Tianzige or Mizhige?
Tianzige is enough if you only need the center cross. Mizhige adds diagonals for angle practice.
How do I remove bold lines?
Set the major interval to 0 to remove bold lines.
What cell size should I use?
15 mm is standard, and 20 mm works well for beginners. Increase the cell size if writing feels tight.
What should I enter first?
Start with the minimum required inputs shown above the calculate button, then keep optional settings at their defaults for a first pass. After getting a baseline, change one parameter at a time so you can explain which assumption moved the output.
How precise are the results?
The calculator keeps internal precision and rounds only for display. Small differences can still appear if another tool uses different constants, period conventions, or rounding rules. Align assumptions before comparing final values.
