If I select a collection of images in LR, is there a way to determine the file size (i.e. in Mb or Gb) of all of the images as a group?

Thank you kindly.

No. Hmmm, sorry, there's not a longer way of saying that!

Just curious: Why do you need that information? When you need images for something special, you’d normally export them. Exported images -especially when created from raw files- can have a very different file size than the original.

No pressing need. I plan to be in Sicily for the month of September. I will be backing up my photos on a laptop that I recently bought. Anticipating the number of images that I will likely take, I wanted to make sure that the remaining hard drive capacity would be adequate. I had no problem doing an estimate. But I was just curious if there was a way to ascertain that file size. No problem though. Thanks for the response.

When you format your cards....how many images does it say will fit? When I format my 128GB cards in camera, it says there are is room for 9999 images. So I know for each 128GB of space, there is room for 10,000 images. If you shooting with a camera that has a large sensor size like a Sony A7III, then it might be more like 5,000 images in 128GB of space. On my iPad Pro 512GB I have room for over 30,000 raw files.

For your exact problem, I’ve observed that the size of my raw and JPEG files don’t vary all that much for a given camera. In my case, each pair is about 25MB. So I use that to calculate how much SD capacity I’ll need for a trip.
