: Digital design - screen grab large dimensions? I'm working on some site banners that need updating and I'm having a few issues with dimensions. My internet screen is set to 'view actual size',
I'm working on some site banners that need updating and I'm having a few issues with dimensions.
My internet screen is set to 'view actual size', so it's not zoomed in and my images/slices are always saved at 72ppi (not that it matters much for online?).
When i screen grab one of the existing banners from the website, with a view to keep the size the same and simply refresh the image to send to the developers, I'll drag the screen grab into photoshop and draw a slice around it. The dimensions of the slice are 1553px x 330px.
However, the developers have asked for the dimensions to be 786px x 164px, and have apparently had to resize all my previously supplied banners which were 1553 x 330.
Any ideas on why the two dimensions would be so different? I can't understand how they can have such a gap in size.
Any ideas/suggestions would be very much appreciated!!

It sounds like you're taking these screenshots from a MacBook with Retina Display.
I struggled with this for a while myself, but I found this great free app called RetinaCapture (http://www.retinacapture.com/) that lets you work around the problem without having to fiddle with the CLI.
Do not rely on dpi for measurements: you want to work with exact pixel dimensions always. If you screen grab something, set your pixel dimensions directly.
If you re using a device such as a Mac with Retina, it is possible that the mac is "pretending" to be one pixel resolution (such as 1920x1080) but actually rendering at a higher resolution. In this case "actual size" is not what you think it is, because the software is scaling things "behind your back."
