How do I enter an aspect ratio for the crop tool?

Is it possible to save a ratio? I often use A4 or 1.414 (it’s a common, important page format)

Hi Andrew - - Whilst NOT an exact solution to your requirement, it may help to note that one of the standard ratios provided is 7/5 … which is very close (close enuff ??) to A4 = 1.414.

@John-M it depends on the size of the print. At small sizes the difference is trivial, but for a large canvas print the difference puts the edge wrap off by as much as 1cm. Even if you allow that much margin for error on the wrap you still have a hassle with the signature and numbering placement.

You can always save it as a preset. For precise DIN ratio figures, consult this page:

A4 paper measures 297 by 210 mm. This corresponds to a ratio of exactly 99:70
Note that other A paper sizes can differ slightly.

For printing, look at this thread (or any other that deals with it):

The margins dialogs in PL4 print

Is the print window in beta ? [probImprimer_1] ! The values on the margins bear no resemblance to the actual margins as seen in the preview. [probImprimer_2] ! Moving one single margin, the leftmost (as seen, not relative to the photograph) affects the other margins. Again none of this is reflected in the dialogs. No undo/redo, no reset… I did not choose a printer so it so conflict with driver shouldn’t be a factor. Kesako ? Thanks

Thanks, that’s a nice workaround idea! I’m sure it doesn’t matter which exact size in the √2 proportion I choose for it since once the crop is there it can be scaled keeping the proportion.

It might matter when printing. For (full)screen viewing, A ratio is utterly irrelevant because of current screen offerings… Also, sqrt(2) is the underlying idea of A ratio paper mostly and the paper you get can be off one or two mm, which can make a difference - if the printer can locate the image that precisely

We had been asking for A ratio for years and what we got was this version
