Guide to Measuring Your Room
Draw the shape of your space and all the openings on each wall. This does not have to have any particular scale, as long as you accurately show wall space where it exists between windows/doors and between windows/doors and walls.
Note which walls are interior walls and which are exterior walls. Also note which rooms other doorways lead to.
From here you can measure along the baseboard, the total length of each wall and note it on your drawing.
Beginning in one corner, you can now measure from the corner to the first opening, on the outside of the trim, then the total width of the opening from the outside of the trim to the outside of the trim. If the wall only has one opening you can stop here, if you have more than one opening, measure between the openings, and then the width of the next opening. Continue this way until you reach the corner you began in.
If you are measuring windows, it can be important to know the height of the window, and the height that the window is off the floor. This can be noted on the floor plan in front of the window being measured
Ceiling height is also important, this can be measured and noted on the sketch as well.
