== Location This page focuses on '''Basics of Areas ==page design and layout'''. It will allow you to continue on [[#Further reading|further topics]] like [[Presentations|Presentations layout]], [[Visual_Debugging|Visual debugging]], [[Floating Objects]], [[Columns]], [[Layers]], [[Grid typesetting]], [[PDF Boxes]]. But first, one needs to understand the basics of page layout by ConTeXt.

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. From left to right, one encounters {{code|leftedge</tt> </td> <td style="text-align:center;width:15%;"><tt>}}, {{code|leftmargin</tt> </td> <td style="}}, {{code|text-align:center;width:50%;"><tt>width</tt> </td> <td style="text-align:center;width:15%;"><tt>}}, {{code|rightmargin</tt> </td> <td style="text-align:center;">}}, and {{code|rightedge </td> </tr> <tr style="background}}. From top to bottom, the areas are called:#cccccc;"> <td style="background:#ccccff;"><tt>{{code|top</tt></td> <td style="text-align:center;">. </td> <td style="text-align:center;">. </td> <td style="text-align:center;">&uarr; topspace &darr;</td> <td style="text-align:center;">. </td> <td style="text-align:center;">. </td> </tr> <tr style="background:#cccccc;"> <td style="background:#ccccff;"><tt>}}, {{code|header</tt></td> <td style="}}, {{code|text-align:center;">}}, {{code|footer}}, {{code|bottom}}. </td> <td style="text-align:center;">E. </td> <td style="text-align:center;background:#DDDDDD;">HEADER<br />&uarr; headerheight &darr;</td> <td style="text-align:center;">g. </td> <td style="{{code|leftmargin}} is the margin area to the left of the main text-align:center;">. </td> </tr> <tr style="background:#cccccc;"> <td style="background:#ccccff;"><tt>textheight</tt></td> <td style="text-align:center;">&larr;leftedgewidth&rarr;</td> <td style="text-align:center;background:#DDDDDD;">MARGINALS<br />&larr;leftmarginwidth&rarr;</td> <td style="text-align:centerarea;{{code|{leftmargin,bottom}|}} is below it, at the same height:20em;background:#EEEEEE;">TEXT<br />&larr;textwidth&rarr;<br />&times;<br />&uarr; textheight &darr;</td> <td style="text-align:center;background:#DDDDDD;">MARGINALS<br />&larr;rightmarginwidth&rarr;</td> <td style="text-align:center;">&larr;rightedgewidth&rarr;</td> </tr> <tr style="background:#cccccc;"> <td style="background:#ccccff;"><tt>footer</tt></td> <td style="text-align:center;">. </td> <td style="text-align:center;">. </td> <td style="text-align:center;background:#DDDDDD;">FOOTER<br />&uarr; footerheight &darr;</td> <td style="text-align:center;">. </td> <td style="text-align:center;">. </td> </tr> <tr style="background:#cccccc;"> <td style="background:#ccccff;"><tt>as the {{code|bottom</tt></td> <td style="text-align:center;">}} area. </td> <td style="text-align:center;">. </td> <td style="text-align:center;">&uarr; bottomspace &darr;</td> <td style="text-align:center;">. </td> <td style="text-align:center;">In between the two lies the area {{code|{leftmargin,footer}|}}. </td> </tr></table>

The names in the column and row headers are the keywords for <cmd>setuplayout</cmd>, the words inside of the table are given to clarify ConTeXT terminology[[Image:layout. There are also keywords suffixed by "distance" to set the distancebetween each svg||||Diagram of the areas, e.g. <tt>leftedgedistance</tt>, <tt>leftmargindistance</tt> (from the named area to the inner). \setuplayout[] dimensions]]

<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|2=[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}}.

When you define a page layout, it's always a right page that you're defining; if you use a double page layout, 'right' and 'left' values are mirrored on a left page. Doublesided typesetting is activated with {{cmd|setuppagenumbering|2=[alternative= Table of Parameters ==doublesided]}}.

== Setup =Paper size =

You define always a right See the dedicated page; if you use a double [[PaperSetup|Paper setup]], it includes details on:* {{cmd|setuppapersize}}, to set the page layout 'right' size and 'left' values paper size* {{cmd|definepapersize}}, to define a new paper size,* the [[PaperSetup#Predefined_Paper_Sizes|many paper sizes already defined by name]]. Their actual dimensions in mm are mirrored on a left given by [[Paper sizes]] page.* [[PaperSetup#Changing paper setup mid-document|Changing paper setup mid-document]]* [[PaperSetup#Setting print size|Setting print size]]* [[PaperSetup#Fitting pages to their content|Fitting pages to their content]] = Example layout =

width=160mm, topspace=20mm, top=0mm, header=0mm, footer=0mm, height=250mm]</texcode> == Let's gather examples here == ; Cover pages: [[Cover Pages]] (2013, 2019); Other: [[Example photo page layout]] (2010) = [[Imposition]] = Imposition is a prepress printing process. It consists of the arrangement of the printed product’s pages on the printer’s sheet, in order to obtain faster printing, simplify binding and reduce paper waste ([https://en.wikipedia.org/wiki/Imposition wikipedia]). We built a dedicated page about '''[[Imposition]]''', because making booklets, to arrange pages in proper order for printing it's a topic in itself. This is where you will use {{cmd|setuppaper}} and {{cmd|setuparranging}}. = 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|2=[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|2=[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...]

You can make all 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> = Table of Parameters = The first column 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 geometry information visible same, but sometimes different; knowing it allows you to invoke it with code like <cmdcode>showlayoutThe paper's height is \the\paperheight.</cmdcode> and Any remarks (usually a short description) are given in the third column. {| class=wikitable! \setuplayout[...] !! dimension !!
