Reports are the most common form of the output produced by genealogical research. The majority of genealogical software puts a lot of emphasis on developing nice looking reports. GRAMPS is no exception in this regard, offering a choice of a variety of reports. GRAMPS can generate reports in a multitude of open formats, both text based and graphical. GRAMPS can also produce screen based reports that are convenient for viewing a summary of your database. Finally, GRAMPS can generate a web site suitable for immediate posting on the Internet.

All reports can be accessed through the menu by choosing ''' Reports ->Report Type ->Particular Report ''' . Alternatively, you can browse the complete selection of available reports along with their brief descriptions in a {{man label|Report Selection}} dialog invoked by clicking the {{man button|Reports}} icon on the toolbar.

All of the reports are almost infinitely flexible. If you wish to modify or extend the default format of GRAMPS reports, you can design and choose the style for each of your reports. GRAMPS provides an advanced interface for customizing practically every aspect of report-styles, e.g. for fonts: type face, size, color and style; for paragraphs: alignment, background color, indentation, spacing, and borders.

Many of the graphical reports allow you to customize the information on the display. Variable substitution is used to substitute date for a particular symbol. There are two styles of variables. The difference between the two styles is how empty data is handled.

this will give a lot of information in the displayed boxes.

Graphical reports represent information in forms of charts and graphs. Most of the options are common among graphical reports, therefore they will be described only once, at the end of this section. The few options which are specific to a given report will be described directly in that report's entry. See also [[#Substitution Values|substitution values]].

The following graphical reports are currently available in GRAMPS:

{{man warn|Single page vs. multiple pages|Depending whether you checked the fit on single page box, the output will be spread over one or more pages. If the amount of included generations is high (say 10) the output on a single page will be very difficult to read on a single (A4) page. On the other hand if you do not checked this box you will end up with a lot of pages!}}

This report produces a chart resembling a fan, with Active person in the center, parents the semicircle next to it, grandparents in the next semicircle, and so on, for a total of five generations.

This report can collect and display a wealth of statistical data about your database. Specific options include filter, sorting methods, and additional birth- and gender-based limit for inclusion into statistics. You can also set the minimum number of items to qualify for the bar chart, so that the charts with fewer items will generate a pie chart instead. The '''Chart Selection''' tab allows you to check which charts you want to include in your report.
