Marquee tool aspect ratio doesn't match same aspect ratio of an object. Why?

For example...I import a jpeg photo into photoshop with a 3x4 aspect ratio (900x1200).

I use the rectangular marquee tool to draw a frame box around the photo, set to fixed 3x4 aspect ratio.

I would expect the box to be the same aspect as image.  But it is always taller...by about 10%.  Very visible.

When I check the info on each object...the pixel count indicate they are both 3x4.  But they don't match up.

Can anyone explain this frustrating problem?

Apologies....I just realized I posted in the wrong group.  This is a Photoshop question not Premiere.  Argh.  I reposted it there.

Sequence settings ... what's the PAR/pixel aspect ratio?

generally in modern times, set the sequence pixel aspect ratio to square unless you're dealing with a legacy format like dv or d1 or hdv and even then it probably makes sense to set the sequence par to square.  Premiere usually does a good job in adjusting clips with non square pixel aspect ratio to display properly when edited into a sequence with square pixels.   Happy to explain what this is all about, but do you really need to know?  Not being snarky, just an ugly legacy of older formats that I had to learn back in the day.

Is there some pixel aspect ratio (PAR) setting on that sequence?

Not sure if this is what you are referring to...When I select the rectangular marquee tool I select a fixed 3x4 ratio.

If you check out the attached screen shot.  You see a 3x4 photo, with a 3x4 black box behind it.  Yet the black box is taller.
