Sizing of PDF doesn't match the sizing in Scribus

[Platter]

Hello,

In my documentsettings I have set my measures to 154x216 mm but when I export my file to PDF they change and my macbook shows me that the actual measures are 174,2x236,2 mm. How is this possible and how can I fix this, please help!

hi platter

it looks as you have set up your document with bleeds of 3mm and either crop marks or bleed marks.
