P: PS 27.4 Setting the default in Preferences > Units to "inches" is ignored by Canvas Size

Adobe Photoshop Version: 27.4.0 2
Operating System: Windows 10 64-bit

When I go to Image → Canvas Size, the default is always pixels. I want it to be inches.

Note: I have checked in preferences, units and measures, and the default is inches. Also when I go to image → Image size, the default is in fact inches, which is what I expect.

Is the default unit for image → canvas size now different? Is there a different place to set it?

thanks

Together with this error, the decimal separator is also not following the global setting. When your decimal separator is a point, you will not experience the issue, but I use a comma and that global setting is not respected in the Canvas Size menu alone.

@Tazing “My default units is millimetres…”

Adobe is aware and is investigating. The workaround until it is fixed is to disable “Modern User Interface” in Preferences > Technology Previews.

My default units is millimetres and canvas size always displayed as millimetres but now going to canvas size, its default display is pixels, I think this happened with the recent update, so each time I have to go and make a change, I need to change the units. Any ideas on how to permanently change it back to the default to millimetres?

This has been reported several times recently. Apparently it’s a bug in the “Modern User Interface”, which you can disable in Preferences > Technology Previews. Then you get the old dialog back.

Recently, possibly since a recent update, the Canvas Size dialog in photoshop looks different: smaller, uglier, and defaults to pixels no matter what my units are set to.

Was always on my default unit settings.

Seems Adobe cant resist making changes for worse?

Try disabling the Modern User Interface in Preferences/Settings. Apparently there are issues with changes not being retained.

Hello

I recently had to reinstall Photoshop (thanks to an Adobe expert screwing up the settings then he left the chat!)

I am looking to change my default CANVAS SIZE from Pixels to CM. I have already got the preferences / units set to CM and when I change the IMAGE SIZE its automatically coming up as CM, however when I go into CANVAS SIZE its always pixels.. I have no idea how to get it back to CM.

Its a weird one, no idea how it happen or how I go about getting it back.

Also my scratch disc options are no longer allowing me to add a second scratch disc - any one able to help on this please?

Thanks

Dave

Dave, can you start a new thread for this “also” part of your question? Your posts were moved by staff to the Primary thread and this part of your question is buried. Please add screenshots and include details about the disk you are trying to add so we can better assist.
