There's also The 25 typesetting areas of a "distance" ConTeXt page are divided into 5 columns and 5 rows. From left to right, one encounters {{code|leftedge}}, {{code|leftmargin}}, {{code|text}}, {{code|rightmargin}}, and {{code|rightedge}}. From top to bottom, the areas are called: {{code|top}}, {{code|header}}, {{code|text}}, {{code|footer}}, {{code|bottom}}. E.g. {{code|leftmargin}} is the margin area to the left of the main text area; {{code|{leftmargin,bottom}|}} is below it, at the same height as the {{code|bottom}} area. In between each the two lies the area {{code|{leftmargin,footer}|}}. The graphic below illustrates the areas and dimensions. The row and column names are writtenalong the edges of the page. The arrows correspond to layout dimensions; themore important a dimension is (i.e. the more of the layout is pushed aroundwhen you change it), the thicker its arrow and the larger its name. [[Image:layout.svg||||Diagram of \setuplayout[] dimensions]] == Defining the layout == Positioning the areasis by setting the following dimensions using {{cmd|setuplayout|[backspace=5cm, ...]}}. The dimensions are mentioned in order of how ‘primitive’ they are: e.g. <tt>leftedgedistance</tt>altering the {{code|topspace}} pushes around all other vertical dimensions, but altering the {{code|header}} affects only the {{code|headerdistance}} and the {{code|textheight}}. 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}}, <tt>leftmargindistance</tt> 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 named {{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 innerheader, 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}}. == Paper size == Page size and paper size are set with {{cmd|setuppapersize}}. Many paper sizes are already defined by name; see the list of [[PaperSizes|paper sizes]]. To define a new paper size, use {{cmd|definepapersize}}.  {{todo | Merge with [[PaperSetup]] }} == Example layout ==

width=160mm, topspace=20mm, top=0mm, header=0mm, footer=0mm, height=250mm]

== Multiple layouts == If you need to use different layouts in some parts of the document, you can set up a global layout, and 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 global layout. To switch to a different layout, call it up in the appropriate place in the document. To revert back to the global layout, use {{cmd|setuplayout|[reset]}}. <texcode>\setuplayout[...] % global layout\definelayout[wide][...] % layout of the first page \setuplayout[wide] % switch to layout called 'wide'\setuplayout[reset] % switch back to the global layout</texcode> To specify in advance that you want to change layouts starting from page 4 (e.g.), use {{cmd|definelayout|[4][...]}}. Resetting the layout must be done explicitly; else, the new layout will be used until the end of the document. <texcode>% different layout for first two pages\definelayout[1][wide]\definelayout[3][reset]</texcode> For the page numbers you can use absolute numbers (as above), relative numbers (like +1, -2) or the keywords odd, even, first and last. <texcode>\setuplayout[ % default layout (right page)...]\definelayout[even][ % different layout on left pages...]</texcode> If you define additional layouts in a doublepage (duplex) setup, remember to think mirrored: leftmargin defines the right margin, backspace is the distance from the spine to the right edge of the text area etc. .<div style="border: 3px solid red; background: #ffcccc; padding: 0.4em;"><div style="font-size: 1.3em; fontweight: bold">Warning!</div>At the moment a layoutchange (setuplayout) inside a page is not proper working in mkiv duplex mode.For more details and actual state see mailing list and [http://wiki.contextgarden.net/User_talk:Zenlima Bug Layoutchange inside page while duplexmode].</div> == Advanced features == * To allow Acrobat Reader users (among others?) to make all layers visible/invisible at will, add the following command at the start of your file:<texcode>\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'']}}, where ''n'' is the number of lines required. If there are not ''n'' lines available, a page break will be inserted at the location of the geometry information visible {{cmd|testpage}} command. * If you need absolute positioning of objects (text, pictures) on the page, but ad-hoc rather than systematic, the [[Layers]] mechanism is more suitable. * For layout from 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 <cmdcode>showlayoutThe paper's height is \the\paperheight.</code> Any remarks (usually a short description) are given in the third column. {| class=wikitable! \setuplayout[...] !! dimension !!

At [http[Category://www.geocities.com/paulhtremblay/context_xml/page2.html Paul Tremblay's] [[XML]] ConTeXt site, there's a lot about layout from a [[Formatting Objects|XML/FO-Issues]] perspective with some descriptive pictures.
