I open an new composer and select ANSI A for my paper. The notation after the name is "Letter; 8.5inx11in", but the width and height are displayed in mm, and the units selection is grayed out, so I can't change it. The rulers at the top and left of the layout are in mm, and the parameters for "Snap to grid" are also in mm. If I then select "Custom", I can select inches for units, and the Width and Height display as 8.5 and 11. However the rulers in the layout are still in mm, as are the units for the grid. Can the entire composer project be converted to inches?

  • All of these questions might be helped by noting QGIS in the title, and putting version and perhaps operating system into the body. – BradHards Nov 29 '13 at 3:44

    @BradHards Please note that it is not necessary to put tags - such as QGIS - into the title. See gis.stackexchange.com/help/tagging – underdark Nov 30 '13 at 11:55
  • I am also having this issue. Can any of the QGIS developers weigh in about it? – Get Spatial Oct 28 '15 at 23:13

You can't (as of 2.12). The "units" selection in the composition properties tab only changes the units for the display page size. Everything else is hardcoded to use mm (ie rulers, item positions, item sizes, etc).


It looks like this problem is fixed in QGIS 2.8.1 : enter image description here

Are you able to reproduce this?

    I am having the same issue as above, and have not been able to reproduce your answer. In my installation, choosing a paper size in inches only changes the presets box. The width, height and units are all still in 'mm', and the units are locked and grayed out. – Get Spatial Oct 28 '15 at 23:13
  • This answer is incorrect- it only applies to the page size, not any other settings like guides. – ndawson Jan 4 '18 at 20:30

This is possible in QGIS >= 3.0.

  • What are the steps to make it happen? I can't figure it out in 3.14 – id est laborum Feb 26 at 21:16
