Build 2/3-column notes for comparison in seconds
Adjust columns, widths, headers, and guide type (ruled/dot) for Pros/Cons, facts/opinions, or K-W-L layouts.
Review the calculations in the "How it's generated" panel and share the URL to distribute the same layout.

Usage tips
T-charts are great for two-way comparisons such as pros/cons or facts/opinions.
For language notes, make the "vocabulary" column narrower and the "meaning/example" column wider by adjusting ratios.
Print at 100% scale (actual size). Use the 50 mm calibration box if you need to verify scaling.
How to use this tool effectively
This guide helps you use 2-column / 3-column notes (T-chart) 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
How do I print the generated note paper?
Open your browser's Print / Save PDF dialog and set the scale to 100% (actual size) with the smallest margins. This keeps the millimeter scale accurate.
When should I use a T-chart vs. a table header?
T-charts start the vertical divider below the header, which works well for comparisons. Table headers let dividers pass through the header, which is better for grid-style tables.
How wide should the columns be?
Equal widths are a safe default. For language notes, try 1:2 (left: word / right: meaning). For research notes, 2:2:1 is a common starting point.
Where is the shareable URL stored?
The shareable URL only stores settings in the address bar. Nothing is saved on the server.
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.
