How to get the size of an object in Photoshop CS6?

I have a graphic on a layer that has been resized by dragging the corners of the item.

Without changing the size of the object, how do I find out the size of the selected object?  The ruler isn't what I need because the transform controls (including those outlining the object) disappear when you select the ruler.

This is crazy.  This should be simple.  This info should always be a available.

The "info" panel is worthless for this.  That makes no sense whatsoever to me.  If you have an object selected, why doesn't the info panel show something about the selected object?

Found it...."You need to get "marching ants" around that button, as though you dragged around it with the marquee selection tool. Do this: hold down Ctrl and double-click on the layer thumbnail in the Layers Panel. This should put those "marching ants" around the button, (and any other non-transparent pixels on that layer). Now you should see W: and H: values, (pixels), in the Info Panel."

But, that's kinda stupid (IMHO).  Size is something you need to know a lot.  It should in the info panel as soon as you select the object on its layer.

Is there any way to make PS CS6 do that?

Bring up the Info panel by selecting it under the Windows tab or press F8
If you select anything it shows the Width and Height of the selection & also shows the estimated finnished document size.

That only tells you the width and height of your selection, not the width and height of an object that has no easily identifiable border.

My object is an irregularly shaped object with a transparent background.  Selecting the object shows the transform handles and broken line border around the object.  But, when I select the select tool, this border goes away.

The method that I found above is more precise, but I still maintain that this info should show just by selecting one or more objects.  Its the most basic measurement that you need in PS.

Press Ctr+T to pull up Free Transform. Without changing the size of your layer, look at the width and height on the tools options bar. It usually says 100% for w and h (since you haven't changed it. Right-click on the 100% and change the units to pixels to see the size of your layer.

To measure an object on screen, simply pull out the ruler (right-click the eyedropper tool and locate it in that tool well) and click and drag across the object you want to measure. You will get a length in pixels.

I found a solution while waiting for a response at EE.

It isn't perfect, but it accomplishes the end goal of knowing an object's exact dimensions.
