Arabic calligraphy styles
Ruq'ah is the hand people actually write with. It was made for speed, so its strokes are short, its letters sit close, and its rules are few enough to remember. That is why it is taught before any other hand.
Ruq'ah is a late Ottoman hand, simplified out of Naskh and Thuluth so that correspondence could be written quickly. Mumtaz Bey set its rules under Sultan Abdulmejid, and it became the standard hand taught in schools and used in government offices. Because it is quick and easy it spread across the Arab world after that and became the everyday handwriting. It is still the first script a pupil learns in a calligraphy lesson, since it has the fewest rules and the fastest movement.
Short strokes, letters sitting close together, and a straight line that does not climb. The eyes of letters such as mim and fa are small and closed, and the heads of the letters are flat and slightly slanted. There are no long stretches and almost no ornament, because the hand was built to be written fast.
It is the hand of handwriting and notes, newspaper headlines and shop signs. You see it wherever something was written quickly and had to be read at a glance.
Write your line, then adjust the slant of the letter heads and how close the words sit, letter by letter, until it reads like a hand, and use the kashida in the few places Ruq'ah allows it. Then export your work as a vector file for print or a cutting file for a sign.
Open the editor, write your phrase, and shape its letters yourself. The account is free and one word is enough to start.
