Master Copperplate, Gothic, and Brush Script lettering with custom ruling guidelines, pressure swells, and export printable practice sheets.
Customize x-height, ascender/descender ratios, and 55-degree slant angles for flawless Copperplate geometry.
Experience authentic flexible pointed nib dynamics with hairlines on ascending strokes and swells on pulls.
No account required, practice smoothly in-browser and print high-resolution ruling PDF practice sheets.
The app generates mathematical calligraphy ruling guidelines (Ascender, Waistline, Baseline, Descender, and 55° Slant lines) tailored to classic scripts like Copperplate, Gothic Blackletter, and Modern Brush. You can practice strokes directly on the pressure-sensitive canvas and export printable ruling sheets as vector PDFs.
The x-height is the vertical distance between the baseline and waistline (the height of lowercase letters like 'x', 'a', 'o'). Ascenders and descenders are proportioned proportionally as ratios of the x-height.
Yes! Click 'Print PDF' to generate an exact millimeter-accurate ruling grid ready for home printing on fountain pen friendly paper.
Copperplate requires a flexible pointed dip nib (such as Nikko G or Hunt 101) to produce hairline upstrokes and thick downstrokes. Gothic Blackletter requires a broad-edge chisel nib (such as Pilot Parallel) held at a 45-degree angle.
