I wish Lightroom had the ability to export images by percentage size
I wish lightroom had the ability to export images by percentage size. That's right, lightroom 3 can't do this. The other competing app can and does it well, and with many canned export presets in place by default.
Some of you may ask why this is important. Well for one thing, customers sometimes asks not for the full resolution of the images, but half the size or a quarter the size. Knowing that the image will be printed small on a page or posted on a website. Also they may not know how it will it be used exactly , but they do know that full resolution is not required. The other issue is file size, sending full resolution images can be problematic for some.
So the question is, what can you do to get this to work in lightroom? Well the answer is Photoshop, are old and trusted friend. As most know, photoshop can reduce image size by percentage.
The solution to get lightroom and photoshop to work together, is with
actions, droplets and lightroom export presets:
1. Create a photoshop Action script to reduce the images.
2. Create a photoshop Droplet to trigger the action
3. Create a Lightroom export preset to trigger the droplet.
4. Destination folder for final images is also required.
Now i'm not going to tell you step by step how to create this workflow in detail here, but there is a great video tutorial posted on AdobeTV.com by the wonderful Julieanne Kost. She shows how to create actions and droplets in photoshop and how to integrate it together with llightroom export presets. Note that the video is not for reducing images by percentage, but the same work flow applies.
Enjoy, Video link below.

I can't agree more about having the ability to resize up as well. I love what you said about being done with it. Work flow is very important, and having a kink in the chain can really slow you down. Case in point, we are talking about something that never should have been left out in the first place. Let's hope the Adobe Gods are listening.
Thanks

Yes, get it? I want to resize say, exactly 250 percent. To do that today, I have to go into Photoshop and figure out the exact pixel dimensions and enter them into the fields. I simply want to have LR export and figure this out for me by specifying I want to size up (or down) and exact percentage.

Rob, one reason to resize by percentage is to conveniently match files that were resized that way prior (perhaps there is a client for whom you've always provided files at 150%). Another is to batch process. Lets say you have a project where you need maximum possible files size, and you empirically determine that the most you're willing to uprez is 300% before degradation becomes unacceptable, but your files are not all of the same size or shape. How would you batch uprez them to 300% by pixel dimensions if they start at different sizes?

As is, there's no way to export cropped photos of wildly varying sizes in this manner -- you get a one-size-fits-all resolution on export, whether it's determined as an overall image bound, a width, a height, or a megapixel number (and the option to prevent upsampling). That means each individual image is scaled to a different degree depending on its cropped resolution, which isn't what I want.
The only way to avoid that is to go through another app, and doing so involves exporting to a lossless intermediate format so my images don't end up being compressed twice, more than defeating the original goal of better quality downsamples.

To date, Lightroom 4.1 offers to resize-on-export with absolute dimensions given in inches, cm, pixel, megapixels or whatever.
Still I couldn't find a way to resize it to 50% in each h/v dimension (that is: 50% width and 50% height, implying a 75% reduction in pixel count).
Or even worse, couldn't find a to specify for example a reduction of 50% in pixel count (effectively resizing by about 70% in each h/v dimension), without having first to sort my photos grouped by megapixels, then exporting them with ad hoc half-megapixel-count value (rounded to the nearest integer, but hey that's life).
The addition of a feature for relative resizing could prove of some use (e.g. to export images at half-res or quarter-res without the need for a calculator at hand for converting % in mpixel count to px in width/height).
Afaik such a feature already implemented in Adobe Photoshop and other hi-tech imaging software (e.g. MS Paint in Windows). I bet the math behind such a resizing feature is not overly difficult - feel free to contact me if you guys at Adobe need some help with the equations, square roots, rounding etc.

LR 4.1: Allow relative (%) height/width on export.

I was going to paste this request myself. Many times I want a 1/2 or 1/4 output scaling option.
