That depends on the type of window you have. Its kind of hard to explain EXACTLY where to measure when we can't see your type of window and you didn't mention what it is.
If you have old double-hung wood windows, you usually open up the window and measure the width of the jamb where the movable sash slides. (1/2" x 1 1/4" interior stops sometimes get removed and then reinstalled after the new window is in) On some windows, this distance will be the same as the distance between the trim on the exterior of the window. (1/2 x 3/4" exterior stops sometimes get removed and then are replaced after the new window is installed.)
To measure the height of the window, you again, open ip the window and measure from the highest point on the sloped sill to the top of the jamb, where the upper window sash meets the top of the window jamb.
These are your exact measurements, and a replacement window is usually ordered 1/4" smaller than that. Sometimes people goof up and the deduction gets made twice (once by the one measuring and once by the one ordering) so don't make that mistake.
Window measurements are always expressed as width x height. Thus, a long narrow double hung window might be 24x61. But not 61x24. This is very important, because you don't want to confuse the two numbers when they are close to being the same... such as 34x36.
