I fully agree. That´s why I was so confused. As long as I don´t convert into pixels, the dpi shouldn't matter.

Sorry, I think I´ve found the solution. It depends on the settings of the document. 96 x 3.12 is 300 which means that the DPI Settings influence dimension of the SVG files. To get the correct dimensions you need to use 96 DPI in the document. I hope this helps everyone who have the same problems.

Dear All, I really like to work with Affinity Photo and Designer. Since I´m Adobe free now, I can´t compare my issue with other vector software but let´s get to the point: When I´m exporting a rectangle with 100mm x 100mm from Affinity Designer and I´m importing it in different kinds of software (Like CAD oder other tools which supports SVG) the rectangle is 312 x 312mm. This means, I need to divide my drawings by 3.12 to get the right dimension after exporting from Affinity Designer. Since this is not really precise and makes everything more complicated, I want to know if there is any setup option in AD to get it out of the software accordingly. THX for your help Mac OS Sierra with the Affinity Designer 1.5.5
