Resizing an image to an exact pixel proportion without getting a squeezing distortion


Question

Here's the issue:

I'm trying to upload a drawing of mine onto Society6, they require the image to be specific proportions of 3300 px wide by 5100 px high. Each time I do this in Photoshop and constrain the proportions, it squeezes and distorts my image, making it skinnier and longer than before.

Does anyone have any advice on how to avoid the distortion while still having the exact size of image they require? I can't crop the image to be any less wide, so I'm feeling a little stuck.

First:

You have to make sure your image is within the Society6 desired ratio. The distortion depends on the initial ratio of the image. To scale the image to 3300px/5100px means the original image has to been in the scale ratio of approximately 0.6471*(Divide the Width by the Height and then Round off to about 4 decimal places)*.

This means if your actual/initial width is maybe 800px, the height should be around (800/0.6471) which is approximately 1236px. As long as the initial scale is not within that ratio, then you have to crop the image to scale before you transform it.

Second:

To Resize/Transform the Image, Open you ratio-scaled image with Photoshop Navigate to the Image sizing through the Image Menu option through Image > Image Size >

From the Image Size dialog window that show up, Change the Width to 3300px and make sure Constrain to proportion link is active(light shade of blue). That way the Height will automatically become 5100px (Or close depending on the rounding off you made when cropping your original image).

Summary: enter image description here

  • I got a sample avatar 256px by 256px(On the Right), with a ration of 1. With a width of 256px, the height has to be (256/0.647) = 395.6111px ~ 395.6px.
  • I then Created a new File and placed my image into it(On the Left) with (256px by 395.6px)
  • Resizing the width to 3300px (Center) gives me a width approximately around 5100px. Thus a distortion less Scaling if you round off well.

Note: However like you notice, Croping will chop off some parts of the image or bring unecessary white space/empty pixels as you notice above. For that case you can do a content aware scale as +ACEkin advises, to get the main content of your drawing "in focus" before cropping.
