Hi Hans,

Some preliminary comments:

1. Ratio-method (preset-1-1)

The width of the typesetting area is set to 2/3 of paperwidth. Only the 
height of the typesetting area is linked to the \layouthwration. - 
Wouldn't it be a good idea to link also the width to the ratio? This 
would preserve the ratio in the paper to the ratio in the typesetting 
area. (\layoutheight/\layouthwratio)

2. Column method
2.1.  preset-2-1
When drawing the diagonal from upper left to lower left on the page it 
appears, that the height of the typsetting area is not to expectation. 
According to my measurings the area is (\c!voetafstand+\c!voet) to high. 
My question is, whether the \v!midden calculation takes precedens to the 
\c!bodemwit calculation or with the \c!bodemwit calculation there is a 
problem. In fact one could also say that the \c!bodemwit is not 
"(2*\layoutvstep)-(....)" but "(2*(\layoutvstep)-2*(....). ?

2.2 preset-2-2
According to the drawing method described by van der Graaf en Tschichold 
(columns), the \c!bodemwit should be 2*\layoutvstep. See also attached 
pdf on page 2.
