If you are using Photoshop 7.0 or CS, got to Window in the menu bar and select info. This should bring up a palette. At the bottom of the palette, the X and Y coordinates of the cursor are show. The Width and height of any selections are also shown.

You can also user the Rulers CTRL + R to help out.

Click in the top left of the rulers, and drag to set the 0 point. If you click in either the h or v ruler, you can drag out guidelines. You can snap to these guidelines.

Finally, if you need to change the units of the coordinates from measuring units to pixels, you can do that in the preferences:
Edit > Preferences > Grid & Rulers

If your graphic is for the web, then you can't scale it because all web graphics print at a fixed resolution of 72 dots per inch. You can only change a web image size is by increasing or decreasing the number of pixels in it, and both these options will ruin the quality of the image.

However, If your image is for printing out, or for placement in another application such as Adobe Indesign or Adobe Illustrator, or even Microsoft Word, then the resolution of the image is not fixed, and therefore you can scale the image without reducing the number of pixels within it! What happens instead is that pixels get smaller. This means that it's usually ok to scale the image down, giving a finer resolution. Scaling the image up works also, but this makes the pixels larger. If you scale up too much, then you might start to see the individual pixels, which you don't want.

The part of Photoshop you really need to study, and obtain a thorough understanding of, is the Image > Image Size dialogue box, the single most important window in Photoshop. You need to know exactly how this works. Once you do, all the rest is easy.

To give you a couple of clues.... if you want to scale down an image without changing the number of pixels in it, uncheck the "Resample Image" box at the bottom of the dialogue and trype a new width and height using measuring units such as inches or pixels. This will scale the image without imapiring the quality. But this will not work for the internet.

It would help if you let me know what you are working on, otherwise, hope this answers you question.
