3 - Lightroom: Bleed


Let's say you want to print a photograph of Chinese Lantern plants.


Your photograph was taken with a typical digital SLR camera, so the aspect ratio is 3:2.

You want to print it on 11" x 14" paper.

The aspect ratio of this paper size isn't 3:2.

You could crop the photograph.

The cyan areas below would be cropped.


We'll make the photograph "fill up" the paper as much as possible without cropping.

The photograph:

• Will cover the paper from left to right.

• With borders on the top and bottom.

Margins = Borders

Lightroom uses the term margins instead of borders.

Get the Margin & Cell Sizes

Click one of the following methods.




1) Download the spreadsheet from here.

If your computer can't open an Excel spreadsheet, download and install OpenOffice.

2) Open the spreadsheet.

You'll be using at the left and right sides.

Ignore the middle.

3) Enter the paper size—Step 1 on the spreadsheet.

4) Enter zeros for the size of the left and right margins—Step 2 on the spreadsheet.

5) The spreadsheet computes the margin and cell sizes for you.

The values for Lightroom are located in the pink table on the right side of the spreadsheet.

Click continue.



Look for the paper size that you're using in the first column.

Use values for the margins and cell size in Lightroom.

Left & Right Margins Top & Bottom Margins Cell Size
5" x 7" 0" .167" 4.667" x 7"
8" x 10" 0" .667" 6.667" x 10"
8.5" x 11" 0" .583" 7.333" x 11"
8" x 12" 0" .0" 8" x 12"
11" x 14" 0" .833" 9.333" x 14"
16" x 20" 0" 1.333" 13.333" x 20"
17" x 22" 0" .167" 14.667" x 22"

Back to the Example

We're going to print the Chinese lanterns photograph:

• On 11 x 14" paper.

• With no left or right borders.

• The top and bottom margins are .833".

• 9.33" x 14" is the cell size.

Left & Right Margins Top & Bottom Margins Cell Size
11" x 14" 0" .833" 9.333" x 14"
