Kitchen Cabinet Bi Fold Door Hardware - Step-by-step instructions for measuring your own face frame cabinets for new cabinet doors. Most cabinet companies would like you to give them the true door dimensions rather than the rough openings. Rough openings will be the actual measurements of these rectangular holes on your cabinets that you would like to pay with cabinet doors. You'll need to take these measurements and convert them into door dimensions until you order. Check your cabinet openings to find out if they are square. If the measurements are exactly the same, then your opening is square.
If they are not, then you may wish to gauge the diameter at the top and bottom and take the larger of the two. Same thing goes for the elevation, measure height on the left and right sides and take the larger of the two. You now have the rough opening measurements. So to make it easier to fit your new doors to your current openings, you might want to make a sketch of your cabinets and number them on paper. This will make mounting the new doors much easier, especially in the event that you've got several doors which are near the same size. Now that you've got the rough opening measurements, what do you do together?
You now need to make a determination. How many overlays would you wish to have in your face frame cabinets? Bear in mind how broad are the stiles between openings? Stiles is the perpendicular strips covering the edges of the cabinet box. If two doors are side by side and hinge on hinge, they will either require clearance to swing open without hitting another door, even if that door is open also. The amount of clearance is primarily a function of which hinge you're using. Check with your own hinge maker to find out how much you want. Most hinges will need anywhere from zero clearance up to a quarter of a inch.
You'll also need to see how much clearance there is between the surface of the opening and your countertop or drawer fronts. Examine the bottom for any decorative moldings that might hit the base of your doors and adjust accordingly. Most face frame overlay doors possess an overlay in the quarter of an inch to as much as three-quarters of an inch. Rarely, you might have overlays outside this range, but they do happen and are often for only a few doors on a classic cabinet. An overlay of one-half inch is possibly the most common, and the one we'll use for our examples.
For unmarried openings, that is a opening on your cabinets which will have a door covering the whole opening, take the width and height of the opening and add 1 inch to the width and height and that will give you a half inch overlay on all four sides. For instance, if the rough opening is sixteen inches broad and half dozen inches tall, you will need a door seventeen inches wide and thirty-three inches tall.
