This plug-in helps you calculate the print size of your photos at various resolutions and determine the optimal size of your prints.

  • How large can I print my photos?
  • How bad will my photos turn out if I print them at this size?
  • What is the best print size for my photos photos?
  • Which of my photos can I print at this size?
  • How well these photos match the print format I chose?
  • How large my photos need to be in order to print well at this size?

These are just few common problems the plugin can solve!

The original idea of this plugin was suggested my Mr. Thomas Kemnitz ( when he was looking for a tool to optimize the layouts for his photo books.

Thomas has also put together a screencast demonstrating the plugin in action:

Requirements and Compatibility

The plugin supports both Windows and OS X, and is compatible with the following versions of Lightroom:

  • Lightroom 2 (2.4 - 2.7)
  • Lightroom 3 (3.3 - 3.6)
  • Lightroom 4, 5, 6 / CC 2015, 7, 8, 9, 10, 11, 12 / Lightroom Classic


This plug-in is released as Shareware (no source code provided). The license allows you to install the plugin on two computers, for example a desktop and a laptop computer, owned and operated by a single user.

When Lightroom is upgraded to a next major version (e.g. 9, 10, etc.), a new registration code needs to be purchased, unless your most recent purchase was made within a 3-month period before the release of the most recent Lightroom's major upgrade.

Demo Version Restrictions

The unregistered version has no functionality restrictions. You may use the unregistered version at no charge for 10 days. After the trial period you will be required to purchase your personal registration code to continue using the plugin.
