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

Uncheck “Relative” in the Canvas size dialog.

Ctrl or Cmd R to show Rulers, then right or ctrl click on the ruler to set your default measurement units. If you choose inches, Canvas Size shoulld default to inches.

Thanks! I did that and Image Size defaults to inches, but Canvas Size remains at Pixels…. 🤷🏻

Strange. It works in Macos 26.4.1/Ps 27.5

Try manually changing it to inches and see if it stays.

Check under Preferences > Units and Rulers and try restarting Photoshop.

Hello all!

For the past version or two Photoshop changed the way a size can be changed. The default used to be that you just say the new canvas size, and it sets to the new number. Now it asks for the difference between the current size and the one you want. Which requires a ridiculous amount of math to get to the exact decimal point you need. There’s gotta be a way to set it back to simply state the desired new canvas size, right?? Anybody know how to do that?

(Also how to default it to be in inches vs. pixels.)

Thanks!

Can you tell us if “Relative to current dimension is checked? If so, turn it off.

(Also how to default it to be in inches vs. pixels.)

See if the answer in the highlighted reply helps:

As is always the case, a new poorly-tested, poorly-executed “improvement” is the cause, and the solution is to find where the offending non-improvement can be disabled, followed by disabling, followed by a few curse words about dumb thing Adobe does all the time.

Pixels are more precise because our screens consist of pixels.

Inches are used for printing, not measuring objects on a screen.

This is a known issue and Adobe is aware. See this primary thread:

I cannot reproduce the issue at current (on Photoshop 27.4.0).

I’m on 27.4 as well. Happens every time for me.

@jnwbr 27.5 was just released. I haven’t heard if this issue was fixed or not. See my earlier link for the Primary thread.

If I have my rulers set to Inches, why does the Canvas Size dialog box default to Pixels?

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.
