what should I do to widen the texwidth?

The horizontal dimensions are determined by the three values
- backspace (distance from the left/inner margin)
- cutspace (distance from the right/outer margin)
- width (width of the textblock)
Normally you need only two values because when you set
backspace + width the cutspace is > calculated and when
you set backspace + cutspace you can write width=middle
and the width of the text block will be calculated.
Which is a good explanation, and he explains how vertical dimensions
work, too. Allow me to add this e-mail to answer another question you
will probably have: "What about the marginwidth, margindistance,
edgewidth, and edgedistance? Those are also horizontal values!"
A good question. The answer is that ‘margin’ means two things:
1. the space between the edge of the textblock and the boundary of the
paper
2. a typesetting area inside that space, in which marginal material is
typeset.
Inside \setuplayout, margin has the second meaning: marginwidth is the
width of the margin, and margindistance the distance between the text
area and the margin area.
There are also the ‘edges’: these are typesetting areas outside the
margin areas. Some uses I can think of: colouring the edge of the page
in a guidebook with sections; placing informative marks in general;
printing a sort of vertical header/footer; etc.
This is not a bad reference:

I wrote a short seven page example where you can see both margins
don’t influence the layout because they’re just put on the sides like
attachments.
\setuppapersize[A4][A3]
\setuplayout
  [location=middle,
   header=0pt,
   footer=0pt]
\setuppagenumbering[location=]
\definefont[BigFont][Mono*none sa 4]
\starttext
\showframe[page]
\centerbox{\BigFont PAGE}\page
\setuplayout
  [backspace=2cm,
   cutspace=2cm,
   width=middle,
   topspace=2cm,
   bottomspace=2cm,
   height=middle]
\showframe[text]
\centerbox{\BigFont TEXTBLOCK}\page
\setuplayout
  [header=2cm,
   headerdistance=1cm,
   footer=2cm,
   footerdistance=1cm]
\showframe[header,footer]
\centerbox{\BigFont HEADER/FOOTER}\page
\setuplayout
  [leftmargin=2cm,
   leftmargindistance=1cm]
\showframe[leftmargin]
\centerbox{\BigFont LEFTMARGIN}\page
\setuplayout
  [leftedge=2cm,
   leftedgedistance=1cm]
\showframe[leftedge]
\centerbox{\BigFont LEFTEDGE}\page
\setuplayout
  [rightmargin=2cm,
   rightmargindistance=1cm]
\showframe[rightmargin]
\centerbox{\BigFont RIGHTMARGIN}\page
\setuplayout
  [rightedge=2cm,
   rightedgedistance=1cm]
\showframe[rightedge]
\centerbox{\BigFont RIGHTEDGE}\page
\stoptext
