== Location of Areas ==For more on [http://context.aanhet.net/svn/contextman/context-reference/en/co-pagedesign.pdf layout and page design] see the [http://context.aanhet.net/svn/contextman/context-reference/en/co-pagedesign.pdf manual chapter].
You can use these design == Typesetting areas in your page:==
<table> <tr style="background:#ccccff;"> <td style="background:#ffffff;"></td> <td style="text-align:center;"><tt>The 25 typesetting areas of a ConTeXt page are divided into 5 columns and 5 rows.

<tt>height</tt> is normally used instead of <tt>textheight</tt>, it is == Defining the sum of <tt>footer + footerdistance + textheight + headerdistance + header</tt>layout ==
The size of Positioning the margins does not affect areas is by setting the size following dimensions using {{cmd|setuplayout|[backspace=5cm,...]}}. The dimensions are mentioned in order of the text areahow ‘primitive’ they are: e.g. Control altering the size of the text area with backspace, {{code|topspace}} pushes around all other vertical dimensions, height but altering the {{code|header}} affects only the {{code|headerdistance}} and widththe {{code|textheight}}.

== Setup =={{todo | Merge with [[PaperSetup]] }}
You define always a right page; if you use a double page == Example layout 'right' and 'left' values are mirrored on a left page.==
width=160mm, topspace=20mm, top=0mm, header=0mm, footer=0mm, height=250mm]
You can make all the geometry information visible with <cmd>showlayout</cmd> and the [[Visual Debugging|related commands]].== Multiple layouts ==
See <cmd>setuplayout</cmd> If you need to use different layouts in some parts of the document, you can set up a global layout, and <cmd>setuppapersize</cmd> in then define additional named layouts for the deviating parts. You only need to specify the dimensions that differ: unspecified dimensions will be inherited from the manualglobal layout.
If you need an unusual paper sizeTo switch to a different layout, call it up in the appropriate place in the document. To revert back to the global layout, use <{{cmd>definepapersize</cmd> and have a look at our list of [|setuplayout|[PaperSizes|paper sizes]reset]}}.
For ConTeXt users in the United States, use
for standard U.S Letter-sized paper (8.5"x11.0")
== Keep ==If you have a certain run of text To specify in advance that you want to keep togetherchange layouts starting from page 4 (e.g.), you can test for the number of lines available on the current page with \testpageuse {{cmd|definelayout|[4][n...] where n is }}. Resetting the number of lines required. If there are not n lines availablelayout must be done explicitly; else, a page break the new layout will be inserted at used until the location end of the testpage commanddocument.
== Multiple layouts == If For the page numbers you need to can use different layouts in some parts of absolute numbers (as above), relative numbers (like +1, -2) or the documentkeywords odd, even, you can set up a global layout for the overall first and then define additional named layouts for the deviating parts. These settings go into the setup area of your documentlast.
That takes care of the global layout. When If you want define additional layouts in a doublepage (duplex) setup, remember to switch think mirrored: leftmargin defines the right margin, backspace is the distance from the spine to a different layout, you just call it up in the appropriate place in right edge of the document:text area etc.

At [http://getfo.sourceforge.net/context_xml/index.html Paul Tremblay's] [[XML]] ConTeXt site, there's a lot about layout from a [[Formatting Objects|XML/FO]] perspective with some descriptive pictures.{{Getting started navbox}}
{{Todo|Unfortunately it's not that easy to define a layout. We need more documentation about which parameters define which length, what influences what else etc.}}[[Category:ConTeXt-Issues]]
Hints about different layouts
< [[Visuals]] | [[Layers]] | [[Columns]] | [[Visual Debugging]] | [[Paper sizes]] >
The graphic below illustrates the areas and dimensions. The row and column names are written
along the edges of the page. The arrows correspond to layout dimensions; the
more important a dimension is (i.e. the more of the layout is pushed around
when you change it), the thicker its arrow and the larger its name.
You always define a right page; if you use a double page layout, 'right' and 'left' values are mirrored on a left page. Doublesided typesetting is activated with {{cmd|setuppagenumbering|[alternative=doublesided]}}. # Set the {{code|backspace}} and {{code|width}}, and the {{code|topspace}} and {{code|height}}. The {{code|width}} is the width of the main typesetting area; the {{code|backspace}} is its distance from the left edge of the page. The {{code|height}} is the distance ''from the top of the header to the bottom of the footer''; the {{code|topspace}} is the distance from the top edge of the page to the top of the header.# Set the {{code|header}} and {{code|headerdistance}}, and the {{code|footer}} and {{code|footerdistance}}. The {{code|header}} is the vertical size of the header area; the {{code|headerdistance}} is the distance from the header area to the text area. The {{code|footer}} and {{code|footerdistance}} work likewise.# Once the header(distance) and footer(distance) are subtracted from the {{code|height}}, what remains is the {{code|textheight}}: the height of the main typesetting area. Although it would be very useful, you cannot set this dimension directly.# If you want to typeset anything above the header, define {{code|topdistance}} (the distance from the top of the header to the bottom of the topmost typesetting area) and {{code|top}} (the height of the topmost typesetting area). For typesetting below the footer, define {{code|bottomdistance}} and {{code|bottom}}.# As for the horizontal dimensions apart from the {{code|width}}: starting at the left edge of the main text area, and moving away from the center, one first sets the {{code|leftmargindistance}}; then one sets the width {{code|leftmargin}} of the margin typesetting area; then one sets the {{code|leftedgedistance}}; and then there is the {{code|leftedge}} typesetting area. On the right: {{code|rightmargindistance}}, {{code|rightmargin}}, {{code|rightedgedistance}}, {{code|rightedge}}. = Table of Parameters = Paper size ==

== Advanced features ==
* To allow Acrobat Reader users (among others?) to make layers visible/invisible at will, add the following command at the start of your file:
<texcode>
\setuplayout[wide] % switches to layout called 'wide'showlayoutcomponents
</texcode>
* If you have a certain run of text that you want to keep together, you can test for the number of lines available on the current page with {{cmd|testpage|[''n''Note]}}, where ''n'' is the number of lines required. If there are not ''n' Use reset to revert back to ' lines available, a page break will be inserted at the location of the {{cmd|testpage}} command. * If you need absolute positioning of objects (text, pictures) on the page, but ad-hoc rather than systematic, the global [[Layers]] mechanism is more suitable. * For layoutfrom a [[Formatting Objects|XML/FO]] perspective, with some descriptive pictures, see At [http://getfo.sourceforge.net/context_xml/index.html Paul Tremblay's] [[XML]] ConTeXt site. == Table of Parameters ==
The first colum is the name by which the variable is set in {{cmd|setuplayout}}. The second column is the name by which TeX stores the variable. This name is usually the same, but sometimes different; knowing it allows you to invoke it with code like <texcodecode>The paper's height is \setuplayout[reset] % reverts to the global layout\paperheight.</texcodecode>Any remarks (usually a short description) are given in the third column.
