Hi Adobe Community,

 

I'm running into a strange error with a project I'm currently working on. In the bottom left corner of the Photoshop window, where it shows your document size, PS is telling me that I'm currently at 469 MB. However, upon saving out, the file ends up at a whopping 1.6 gigs.

I've been using Photoshop for years in my profession, and I haven't done anything different as far as my workflow goes with this particular file. It's actually one of many files that I created for a coworker that all use the same elements for the most part, so I'm having some trouble wrapping my head around this one.

Anyone have idea ideas? I can share the file if need be. Thanks in advance!

Chris

Photoshop's document size indicator is a simple calculation based on pixels x 3 for 8 bits/channel (or x 6 for 16 bit)  x layers. However in that count, smart objects are counted as a single layer and the count does not take into account their content , which can be multiple layers and even further nested smart objects. This can lead to a much bigger , and more realistic, file size when the file is saved. Dave

Thanks for responding, JJMack.

So I believe I ran the script properly according to your previous post; however, I'm not seeing any decrease in file size. If you care to give it a shot, here's the a download to the file: https://www.dropbox.com/s/6ro1py4y5pjtx9t/lineup_updated.psd?dl=0

I appreciate your help already, nonetheless!

That definitely makes sense to me. I do have multiple smart objects throughout the file; however it's such a dramatic increase in size that I felt like it had to be an error. It very well could be just that - I just know that I've made files similar in the past that never scaled up to that size. I'm going to rasterize all of them now as a test.

Well it looks like we have a winner. The smart objects are to make the job easier for the one who will be updating the files, as there are three different artboards at different sizes. I guess he'll just have to update them manually one by one!!

Thank you for talking this sense into me!

No problem. That document size indicator can be misleading unless you realise how it is calculated 🙂
