Enter a numeric size (any units) for one dimension of your design (typically the canvass). The Calculator will output a series of golden ratio higher M1 and so on, and golden ratio lower D1 and so on.
Mn = M0 × Φn
Dn = D0 ÷ Φn
Mn+1 = Mn + Mn-1
Dn+1 = Dn + Dn-1
To get a set of "Total / Long / Short" take any 3 numbers in a row M1 M2 M3. The largest number will be the "Total" value and the middle will be "Long" and the lowest "Short." This includes M1 M0 D1.
