如何使用「格子纸生成器（方格/田字格/米字格/横线/点阵）」？How do I use the Grid Paper Generator?
选择纸张类型、纸张尺寸和格子大小（毫米），调整线条颜色和页边距，右侧预览实时更新。下载 PDF 打印时请选择「实际大小 / 100%」，这样格子尺寸才准确。Choose the paper type, page size and cell size in mm, adjust the line colour and margins, and the preview updates live. When printing the PDF choose Actual size / 100% so the cells measure correctly.
打印出来的格子大小不对？Printed cells are the wrong size?
打印 PDF 时请在打印对话框选择「实际大小」或缩放 100%，不要选「适合页面」，否则打印机会按比例缩小，格子就会偏小。In the print dialog choose Actual size or 100% scale instead of Fit to page; otherwise the printer shrinks the page and the cells come out smaller.
田字格选多大合适？What cell size suits a tian grid?
小学低年级练字常用 15–20 毫米，高年级和硬笔书法常用 10–12 毫米；坐标纸默认每小格 1 毫米、每 5 毫米一条粗线。Early primary pupils usually use 15–20 mm cells, older pupils and pen calligraphy 10–12 mm; graph paper defaults to 1 mm squares with a bold line every 5 mm.
