Determining diameter of headset and handle bars

I need to order a different stem for my bike and I am not certain how to measure the existing headset and handle bars so I order the correct sized stem. Do I take the stem off and simply use some calipers to measure the diameter of the headset? The bike a 2002 Trek 5500 full composite frame with a chris king headset.

Normally the size will be either stamped, or more commonly printed on the bar & stem, if not, measure them, say with a vernier caliper.

For the steerer size, unless your using a shim, you should just be able to take the top cap off, and measure what's underneath.

You could have just measured it yourself.
