Arabic sign design: Right to left and left to right multi-script wayshowing systems and sign design

In the Middle East, the Arabic script is omnipresent and has an ample impact on the built environment. The calligraphic Arabic script is extremely flexible, making its text representation economic. However, in physical signs, calligraphy is replaced by Arabic typography, whose type choices may not capture the full flexibility of the Arabic script. Additionally, the graphic logic of dual language sign systems is not as straightforward when applied in Arabic, since the Arabic reads in two directions: right to left for the script and left to right for the numerals. Multi-script signage involving Arabic requires a heightened sensitivity regarding the information sequence.
