Hello,
it is a completely necessary option, not only for art work but
and in any other product whose price is calculated with the surface dimensions. Sale of fabric, shading awnings, wallpapers, window blinds and more…
Example of shading tent calculation:
6.45m x 4m = 25.8sq.m
25,8sq. m x 12€/m = 309.6€
That is (X) x (Y) x (€) = The final price
