Affinity Photo resize canvas not working

[lilystone]

Hi - As a newbie refugee from Photoshop, I have tried to resize my 5.5" x 3.0" canvas to 6.0" x 3.5" but it stubbornly refuses to change the height to 3.5", it insists on 3.0". I do not understand the hangup. Also, I try to change a document's units from pixels to units and it stays at pixels. What am I doing wrong?

Is the constrain proportions locked? That will stop you.

 

You can change the units in the document if you select the hand and set what you want in Units:

Thank you so much for the answer...

 

First - constrain proportions lock is unlocked. I was able to reset the width, but then when I tried to reset the height somehow it resets to 3.0" instead of the 3.5" I specified.

 

Second - I'm on an iPad Pro, so its seems to work a little differently. Resize canvas doesn't look like your example. I try to reset the units by choosing Resize,  following the right arrow to the hidden dialog box, choosing "inches,", going back to the first dialog box and applying. Nothing. I also tried changing the dpi to 300 and the sampler to Lanczos3 with the same result, nothing. I also tried changing units to inches on the first dialog box, in the width adjustment box, with similar lack of success. Very little I do here "sticks" after applying.

 

Thanks for your help, I'm baffled...

Ah, an iPad, Sorry I know nothing about them. 

 

If you look at the top of the Questions forum page there is a separate iPad forum (or sub-forum) called "iPad Questions"

 

There might be someone there who can give you a quicker (and more useful) answer.

 

I'm not trying to get rid of you or anything

Thank you so much!
