There are two basic ways to go about doing the Golden Ratio (or Divine Ratio same thing.) One is to do math and do the ratio thing by the number.
Not what I do.
Here is a diagram with an explanation below. Rotate it clockwise. For some reason I couldn’t save it in the correct orientation. Also it will go to another page and then click on that link as well and it will download.
In this case it is all about a straight edge and a t-square (or something guaranteed to give you a ninety degree angle straight line) and it will work on any right angle quadrangle. A right angle quadrangle is any four sided figure with all ninety degree angles. And it works on portrait and landscape orientation.
If you are doing this for a single page artwork that could be framed I strongly recommend putting a 1″ buffer all the way around your work space for the matting. THEN do the Golden Ration INSIDE this new work space.
– Step 1 – Find the center of your work area. You do this by drawing lines to opposite corners of the work space in a large “X” shape. The point where the two lines cross is the center of your work space. Take your square and draw a line straight UP to the top of your work space. (this line is not in the diagram. In fact you can just mark the top of your work space without drawing a line to it.)
– Step 2 – Draw 1 line each from this center top point to each of the bottom corners of your work space.
– Step 3 – Where The lines cross ( in the diagram blue and green) Draw a line straight up to the top of your work space.
– Step 4 – From the left top point draw a line to where the right crossing point is (in the diagram that point is labelled “F”. From the right top point draw a line to left crossing point (in the diagram that point is labelled “H”)
– Step 5 – Using your square – At point “R” in the diagram draw a line over to the left line. Stop when you touch this left line. If you are making a double column start again at Point Q and draw over to the right ling. If you are just using one work space start at “R” again and draw over to the right line.
– Step 6 – Using your square – From these stopping points draw a line straight down until you run into a line, stop at the line.
– Step 7 – If you are using a single space simply connect the two bottom dots and you have your work space. Congratulations.
– Step 7A – If you are creating columns draw a light line all the way across the bottom using the two bottom points as your start and finish. Then using a square draw a line from R to the bottom line and draw a line from the Q to the bottom line. Erase the line between the two boxes you have just created.
Hopefully these directions are useful and helpful.
I much prefer to teach this in person as the description can get very technical and things can be lost in the writing. However, in person, it flows very easily.
