Hello, I am new to lightroom and basic on computers. Can you tell me - am I able to resize images all to the same size using lightroom (I have to print these images). I seem to be able to crop - but only the aspect eg 4:3, but i need them to be the same size, not just the same aspect?
You can go ahead and export the images in same size using Lightroom.
Please follow the below link to export the images in same size.
Hope this helps.
When you export the photos, in the Image Sizing section, check "resize to fit" and then enter the size in pixels that you want. For example if you want to print at 8x6, you could enter 2400x1800 (that's 300 pixels per inch).
