This conversation has been merged. Please reference the main conversation: Lightroom: I can't add (certain) custom crop ratios

Lightroom Classic version 8

Original dimensions 7952 x 3501

Wanted to Export as: JPG - 1080 x 717 - File size limit of 300K,

Cropped to a ratio of 4:3 3:2 - I actually entered 1080 x 717 in the custom size to be safe.

After exporting the resulting JPG the dimensions were 1075 x 717 - 5 pixels short of 1080.

Tried not restricting file size, amongst other settings. No luck.

Did an Photo > Edit in > Photoshop. 

I did not change the crop and, went straight to File > Export > Export As: JPG at 1080 x 717. The resulting file came out at the right size (1080 x 717).

I was actually trying to help someone remotely. So, I replicated their settings. At least two of us have encountered this problem.

Hi Laurence
1080 x 717 is not the same ratio as 4x3.  In fact it's only a few pixels off 3X2  (1080x720). 
When I try to crop an arbitrary photo to 1080 x 717 LR (LR Classic, 8.0) assumes I mean 3x2.  Then when I export with long dimension constrained to 1080 I get 1080 x 720, as expected.
As it happens, your 1075x717 is almost exactly 3x2.

If you really want a 4x3 crop with 1080 as the long dimension, I suggest you crop to 4x3 and export constraining long dimension to 1080.  I got 1080 x 810 ( 4x3) as expected.

"1080 x 717 is not the same ratio as 4x3"
That was my fault I quoted the wrong amount. I actually get 2x3 / 4x6

Well I'm not happy with any program that makes an assumption about what I want. As I said Photoshop gets it right.

If you really want a 4x3 crop with 1080 as the long dimension, I suggest you crop to 4x3 and export constraining long dimension to 1080.  I got 1080 x 810 ( 4x3) as expected.
I want 1080 x 717 px, not 1080 x 810.

You've tripped over a long-standing bug that Adobe has decided not to fix.  I'll merge this into the existing bug report.
