Drawing Arabic letterforms on a tablet: settings that help
Samer
Brush angle, stabiliser and canvas rotation: small changes that make digital lettering feel closer to the reed pen.
Arabic letters are shaped by the cut edge of a reed pen, which a round digital brush does not have.
Use a flat, angled brush
Most drawing apps let you fix the angle of a brush. Around 70 degrees gives thick and thin strokes close to a cut qalam.
Turn the stabiliser up
A medium stabiliser smooths long strokes, like the tail of a noon or a yaa, without making the dots feel slow.
Rotate the canvas, not your hand
Calligraphers move the paper. Do the same with a two-finger twist and keep your wrist relaxed.
Practise with guides
Draw a column of rhombic dots to measure letter heights, as students do on paper. Once the proportions feel right, the guides can go.
