Don’t forget that in Lightroom you aren’t committing to a specific output size when cropping. Instead, you specify the actual number of pixels that are going to be created when you use the Export feature or one of the Output modules (Slideshow, Print or Web) to create a raster (pixel) based image.

While using the Crop tool, you can select from the list of default/preset aspect ratios, or choose Enter Custom from the list and create your own. Lightroom will save the last 5 custom aspect ratios entered.
• “X” flips the crop (horizontal to vertical).
• “A” will lock or unlock the aspect ratio.
