You can drag a rectangle over the object and the width and height will show in the Navigator pallet. Then just delete the rectangle. Also, a ruler is under the eyedroppers but you would have to take two measurments. If you need pixel size, just multiply the dimensions in inches by the "ppi" resolution shown in the Image Size dialog.

You seem confused about the difference between canvas size and image size. If you change the image size from 300×300 pixels to 600×600 pixels, then the actual image will get twice as large (and blurry, but that is another thread).
If you change the canvas size from 300×300 pixels to 600×600 pixels, the image remains 300×300, but there is now 150 pixels of blank area all around the entire image. This makes 600×600 the new canvas size.
In reverse, changing the original picture to 150×150 with image size will reduce the size in half. Doing it with canvas size will cut off 75 pixels from each side (or not, if you choose to cut from one particular side) making the result a 150×150 piece of the original picture … a crude way of cropping.
I hope this makes sense … the best way to figure it out is to play with it a bit. When you see what is happening, it all makes sense.
Make a selection of the object in question, then select File>New Document, and it will show you the size (bounding box) of the what is on the pasteboard (ie – your selection). If you need to know the area of an irregular selection, that is a different story.
Open up the Info pallet. Select the layer. Then Select>Load Selection. Then select "Layer 1 transparency". The size of the
object will be in the lower right hand corner of the Info pallet. If the object is a shape, you’ll have to rasterize the layer
first.

simpler still…
good one Larry
If it’s a Shape Layer, simply CTRL+Click on the icon in the Shape Layer then look at the H:/W: pane in the Info Palette. No rasterizing necesary.
When I need to measure "irregular shapes" for inch measurements, I find a ruler created by one of the "smart people" to be a very valuable tool in my arsenal. I can line it up any way I need to.
Perhaps you could share that again Phos!
Patty 🙂
Hmmm…I’ve been meaning to rebuild that ruler, ticking off finer fractional increments.
