Step 1: What to measure first?
When you are starting to measure, you should begin with the length of the entire wall. If you are using graph paper, draw a line on the sheet and mark the length along the line. It is best to start with a corner to the adjoining wall and follow the wall edge from one end to the other, avoiding any appliances, fixtures, or windows that may be in the way.
Step 2: Measuring Windows and Appliances
After you have the entire length of the wall without any fixtures in the way, you will next need to take into account the space that the fixtures take up. If you have a window on the wall where your cabinets will be going, measure from the corner of the wall up to the window frame, marking it down on the piece of paper. Then measure the window itself from edge to edge and make note of that width as well. Repeat the process for any other windows that are in the room, as well as any existing appliances that are not going to be relocated in the remodel. Mark all of the measurements down on your paper. Take your time doing this; if the measurements are inaccurate, your cabinets may not fit properly.
Step 3: Mark the Fixtures
Start with the wall that has the sink. You will need to carefully mark where any vents are as well as the plumbing and electrical outlets. These can be relocated during your remodel to fit your new cabinetry.
Step 4: Measure the Wall Height
Once you have measured the width of the wall, you will need to get its height. Using the tape measure in a corner, measure the distance from the floor to the ceiling. Repeat this for each corner of the room to be able to make note of any significant settling that your house may have gone through. After you have marked this down, repeat the measurement from the floor up to the edge of the counter top. This will let you know the correct height of the cabinets you will need as well as the counter clearance that you should have, if any. On your paper, note any recessed ceilings, fixtures, or any other feature that may affect the height of your wall and the dimensions of your cabinets.
