Printing to cut-sheet size in Lightroom

Brolgas, Northwest Queensland - Sigma 24-105mm 

For most images, the aspect ratio and the resulting crop are dictated by the elements in the image. But there are times when it's useful to print to a particular sheet and the aspect ratio for that sheet; for example, when an image needs to fit into a particular frame, or for editorial work when the size and ratio may be set by an editor.

Let's take an example. I want the image to fit onto an A4 cut-sheet. An A4 sheet is 210mm x 297mm. But, in this example, because I want a 25mm border all around, the image area will be 160mm x 247mm – 50mm off the height (25mm off the top and bottom) and 50mm of the width (25mm off the left and right).

So here's the brilliant part (Lightroom's, not mine): In Lightroom's crop tool, next to the picture of a small lock is the aspect ratio setting for the image. If you click on that ratio you can select "Enter Custom..." When you do, a pop-up box will appear and you can enter the image ratio – in this example 160 x 247 (that Lightroom will adjust to 1.60 x 2.47). 

When you finally bring that image to Lightroom's print module and set to print on an A4 cut-sheet with a 25mm border all around, your image will fit perfectly (well, within a fraction of a mil).
