Question

Cannot export images above 127ppi from Lightroom Classic.

Hi Folks,

 

I am unable to export jpegs (or any other image file) above 127 ppi from Lightroom Classic. Any time I type a number above 127 ppi and a box pops up saying "Invalid Constraint Size". Any idea why this is happening?

 

I appriciate it makes no difference to an digital image quality but I send images to printers who require a specific ppi (often above 127 ppi!).

 

Thanks!

Just as a follow up - the "Invalid constraint size" is most likely referring to the width/height setting set to "inches" or "cm" in combination with the resolution, where the two together are driving a pizel size that exceeds the maximum pixel dimensions. The maximum size file you can create is 512 Megapixels (536,870,912 pixels). The is approximately 22370 x 24000 pixels for your file. Do you really want to create a file that big?

    Hi Michael,

     

    Thanks for the reply. Even if I am not asking it to resize the image at all, if will not let me go above 127ppi. 

     

    Any idea why it's doing this?

     

    Cheers,

    Sam

    Resize the image*

    *as in I am not asking Lightroom to change the quality or "cm" or "inches" of the image.

    Can you show us your export settings? I have had no trouble setting the resolution to a higher setting.

     

    The "Invalid constraint size" is most likely referring to another setting (not resolution):
