Sorry, Hans, I copied the wrong sample (value for "width" in "\setupinteractionscreen" should read "fit" instead of "max"): \nopdfcompression \setupinteractionscreen [width=fit] \setuplayout [standard] [backspace=.7\textwidth, cutspace=\cutspace, width=middle] \starttext \startmakeup[page] \null \stopmakeup \startmakeup[standard] \null \stopmakeup \stoptext Here are the boxes (using current latest from today [2023.03.06 14:48]): 3 0 obj [ 0 0 595.275590072 841.88975789 ] endobj 7 0 obj [ 0 0 968.199847496 841.88975789 ] endobj Page 1 (object 4) uses object 3 as /CropBox, /MediaBox and /TrimBox. Page 2 (object 7) uses object 3 as /MediaBox and object 7 as /CropBox and /TrimBox (I have just discovered it). I think it is better to avoid having a page with a /CropBox larger than its /MediaBox. But I’m afraid that it is wrong to have a /TrimBox larger than the /MediaBox for the same page. I hope it is clear now. Sorry for the mistake in copying the wrong sample. Many thanks for your help, Pablo

Afaik the standard permits is to one gets what one asks. I will add some checks plus a warning and hopefully not break something.

Many thanks for the check that avoids this issue. As for the specification in re with boxes larger than the media box: In theory, trim and crop boxes may be larger than the media box. But the specification also warns that in that case, “they [would be] effectively reduced to their intersection with the media box” In practice, I see that as an issue of logical consistence. I don’t see a way of cropping or trimming an A5 page inside the boundaries of an A3 page. Of course, I may be missing something, but I see crop and trim as synonyms for cut or reduce. Many thanks again for your help, Pablo
