Frequently Asked Questions
How do I customize the margins before downloading?
On the tool page, use the margin sliders (top, bottom, left, right) to adjust values in millimeters. The preview updates in real time. Once satisfied, click 'Download PDF' to generate your customized graph paper.
Can I change the line color from red to another color?
Yes, the line color picker allows you to choose any color. Simply click the color swatch and select your preferred hue. Red is the default, but you can switch to black, blue, green, or any custom color.
Is the 5mm graph paper compatible with A3 printers?
Most printers support A3 paper, but ensure your printer settings are set to A3 and the paper tray is loaded with A3 sheets. The PDF is formatted for A3 dimensions; printing on smaller paper will crop the edges.
Why is the grid red instead of the usual blue or black?
Red grid lines offer high contrast and are less likely to interfere with black ink or pencil marks. They also photocopy as lighter gray, making them ideal for reproductions. The red hue is easily distinguishable from your own markings.
