Graphics help

[CherylC]

Hello there! New here.  I'm stumped. So I'm making my graphics in Photoshop for phone cases. Just one problem, they are all too big and I'm winding up resizing them and now they look blurry. So I've been making some "Test" graphics, thinking maybe if I make them at a different resolution and pixel size, they'll be the perfect size. Nothing I do is working, they are all coming in too big and I'm still having to resize them, which is something I don't want to do. What am I doing wrong?  I don't get it.

Thanks

For newer iphone cases (iphone 15) create designs that are 4.383 in. by 7.5 in. at 150 dpi.

Or take a screen shot of the zazzle design tool for whatever project you wish to create, paste it into Photoshop, crop everything but the design area (including the bleed lines), set the opacity to 50%, and create your design on top. Delete the guide layer before you save it as a .png file.

Thanks for the response. 150 DPI?  I tried it, it works. 150 Huh...ok then.  Can I ask where you're getting the phone dimensions from?  This should be interesting. All my background graphics are at 300 DPI.
Thanks again.

There is a now non-supported Adobe app called Adobe Design to Print. It was a collaboration with Zazzle where you could easily create images and export them into layers into Zazzle’s Design Tool. The guidelines and dimensions appear automatically. You can still download the app and run it with an older version of Photoshop, which you can download from Adobe Cloud. You can find more details online and on other posts on this forum—mostly posted by me. It’s a fabulous app. I have no idea why Zazzle/Adobe no longer support it. It works fine if you use the correct version of Photoshop,

Don't forget that you can use an image much larger than the design area and then reduce the size right in the design tool so the image fits. If you're using a flattened image, you might want to get the aspect ratio in proportion to the design area. I couldn't find the exact dimensions of the phones, but for example's sake, let's say they're 4 inches wide by 7 inches high. That's a 4 to 7 ratio. This means you can create an image that's 400 pixels by 700 pixels or one that's 600 by 1059 or 800 by 1400 or anything else just as long as the ratio is correct. By the way, I always use images that are 300 ppi and they work just fine. They don't have to be 150 ppi.

That's the problem, when I resize stuff in the design tool - the graphics get blurry.  I guess I just don't understand how Zazzle works and I think I'm gonna throw in the towel.  I just don't understand why there isn't any product dimensions or suggestions on what size/resolution your graphics should be. It's just bizzare. 

But thanks for responding to my topic.

Try one more time. Create an image in Photoshop that's larger than a phone case would be. Say, 10 inches by 6 inches. Use 300 ppi, which means it would be 3000 pixels by 1800 pixels, and make sure you're using either sRGB or Adobe RGB. Save it as a PNG or the highest resolution JPG (I think its resolution would be 12). Upload it to a phone case. It won't fit, but that's not the point here, the point being that things have been blurry. If they're still blurry, then there's something else going on because, for me, Photoshop images are clear.
