To independently design the suite, it is extremely important to correctly calculate the size of the kitchen facades, because the configuration, the final price, the appearance and the correct opening and closing of the cabinets largely depend on them.
Standard or non-standard?
So, if you are at the planning stage of the future kitchen, then, most likely, you already know that you have to buy ready-made fronts from any manufacturer that will offer you products of non-standard and standard dimensions. Before we start calculating and designing, let's see what the difference is between these categories.
- Fronts of non-standard sizes, that is, according to your calculations - this option allows you to maximize the use of available space, optimize the filling of the kitchen set and implement non-standard solutions, but overpay for "non-standard" will be 25-30%, which is palpable, especially if you order facades with expensive lining . Of course, there are also limitations - one finished facade should not exceed 2520 * 920 mm and be less than 110 * 596 mm. Also keep in mind that "non-standard" fronts are manufactured longer for 3-5 days.
- Fronts of standard sizes - they are preferable to use because of, firstly, no extra charge, and secondly, because it is somewhat easier to design the cabinet and pick up the components. In addition, in recent years, manufacturers, following the demand of buyers, have started to produce standard facades for kitchens with low or very high ceilings, so that, more often than not, you can go "in a standard way" without losing anything.
Conclusion: it turns out that it is more profitable and easier to compose a project, adjusting as much as possible to the standard sizes of fronts, but if necessary, order the manufacture of products of unusual width / height.
- Why are "non-standards" more expensive than "standards"? The fact is that the production of standard fronts is essentially a template and does not require reconfigurations of equipment, accordingly labor and time for their production is required less.
Below in the table are the sizes of blind doors, shop windows and facades for drawers.
Standard facade dimensions for kitchen
|Doors, deaf||Showcases||Boxes and cases|
- Attention! At different manufacturers, the standard sizes are slightly different, so the exact parameters need to be specified. For example, fronts with a height of 716 mm are often manufactured instead of the 713 mm shown in the table.
- These dimensions are relevant for any facade: wooden, MDF, particle board, frame, etc. - in fact the main thing here is to keep the right proportions so that the opening and closing and the appearance of the cabinets are correct.
A little "furniture" mathematics - we do the calculations correctly
Now we proceed to calculate the overall dimensions of the facades.
The general principle of calculation is simple: the width / height of the facade should be less than the width / height of the body, therefore, from any width / height of the body, it is necessary to subtract the technological gap:
- Height фасада = высота корпуса – (минус) зазор;
- Width фасада = ширина корпуса – (минус) зазор;
The clearance can be 1-2 mm on each side, respectively 2-4 mm - the gap in general.
It would seem that everything is simple, but there are some nuances for some modules.
Keep in mind that for each module (especially for MDF fronts, since they can not be corrected) it is better to make separate calculations - so you will avoid irreparable errors.
And now let's consider these nuances on the example of a 700x400 mm module, with a total gap of 3 mm.
Nuance 1. How to calculate the width of the facade for a shell with two swing doors?
In this case, from the width of the housing, you need to subtract an additional 3 mm from the gap between the two swing doors. The following calculation is for one door:
- (400-3-3) / 2 = 197 mm
Nuance 2. How to calculate the width of the facade for the case adjacent to the wall?
In case the case is adjacent to the wall, then from the width of the body, you need to subtract 3 mm (for a gap against the wall) and 1.5 mm for a gap with a facade with a neighboring door. Consider this: 400-3 mm-1.5 mm = 395.5 mm.
Nuance 3. How to calculate the size of the facade for the lower shell, located under the table top?
If the table top has a drip tray, then the gap between it and the top edge of the facade should be 4-5 mm. If the drip tray is not provided, then the gap can be made 3 mm.
Nuance 4. How to calculate the height of the facade, located under / above the decorative cornice?
Here, from the height of the body, subtract 3 mm from the abutment to the upper cornice. If there is also a bottom cornice, then subtract another 3 mm (in general, 6 mm).
Nuance 5. How to calculate the sizes of fronts for boxes?
If several identical drawers are provided in one housing, the height of the lining can be calculated using the following formula:
If the case with drawers is located on the floor of the countertop, then we take into account in the calculation an additional gap:
- BK-3x / x
- VK - the height of the shell;
- X is the number of boxes.
Let's give an example: if the height of the case is 860 mm, it has 4 drawers, and the case is located under the countertop, then we get this calculation:
- 860-3 × 4/4 = 212 mm
If it is assumed that the boxes have different heights, the calculation must take into account the height of each box, the number of boxes in the casing and the gap.
To calculate the width of box-like facades the same principles are used as for doors.
