How big is a Tianzige cell? A4 sizes explained
Grade 1: 2–2.5cm per cell. Grades 2–3: 1.8–2cm. Pen calligraphy: about 1.6cm. On A4 portrait with 10mm margins, 2cm cells give nine per row.
Start from the grade, not the paper
Grade 1 needs 2–2.5cm. Smaller cells force a beginner to cram the character; much larger ones let the structure fall apart.
Grades 2–3: 1.8–2cm. From grade 4 on: 1.6–1.8cm, which is also the range used for pen calligraphy practice.
What fits on one A4 page
A4 is 210×297mm. With 10mm margins the usable width is 190mm, so 2cm cells give nine per row and thirteen rows; 2.5cm cells give seven per row.
If your printout is the wrong size
Set scaling to 100% / Actual size. Fit-to-page shrinks an A4 sheet by a few percent and every cell with it.
Downloading the PDF is safer — its physical size is fixed. The editor also offers a 5cm ruler you can print and measure.
