Planning a kitchen space is always a balance between aesthetics, functionality and strict mathematics. When you are wondering how to calculate the area of a refrigerator, we may be talking about two completely different things: the geometric floor area that the unit will occupy, or the useful internal volume of the chambers. For an interior designer and installer, external dimensions are important so that the appliance fits into a niche, and for a home cook or an avid cook, the internal displacement is critical, determining how many products will fit on the shelves.
An error in calculations at the purchase stage often leads to unpleasant surprises: the refrigerator may not fit into the doorway, may not fit between cabinets, or, conversely, leave a huge empty one hole in the headset. Moreover, ignoring ventilation gaps, which also take up space, can shorten the life of the compressor. In this article we will analyze all the nuances of calculations so that your new equipment fits perfectly.
Why you need to know the exact dimensions and area
Understanding how to correctly calculate the occupied area is necessary not only for beauty, but also for operational safety. Many modern models of built-in refrigerators require strict adherence to niche dimensions. If you are mistaken even by a centimeter, the facade may not fall into place or the door will touch adjacent cabinets when opening.
In addition, the area that the refrigerator occupies on the floor affects the distribution of the load. Heavy models, especially two-door ones, can create serious pressure on the floor covering. Knowing the exact dimensions of the supports and the total contact area, you can choose the right protective mats or strengthen the floor at the installation site. Side-by-Side, can create serious pressure on the floor covering. Knowing the exact dimensions of the supports and the total contact area, you can choose the right protective mats or strengthen the floor at the installation site.
⚠️ Attention: Do not forget that manufacturers often indicate dimensions without taking into account protruding handles and hinges. When calculating the installation area, be sure to add 2-3 cm to the depth for protruding elements.
It is also important to consider the area required to open the doors. Even if the body itself fits into the allotted space, the swing radius of the sash may require additional free space. In narrow kitchens, this becomes a decisive factor in determining whether you can use the appliances normally.
How to calculate the base area of a refrigerator
The simplest calculation required when planning is the footprint (footprint). This is the rectangle that the technique forms when viewed from above. To calculate it, you only need the width and depth of the case. The formula is simple: width is multiplied by depth.
However, there is an important nuance here. The depth of the refrigerator is often specified without taking into account the handle and the protruding rear part where the condenser and pipes are located. If you plan to install appliances flush with the countertop, these protrusions can ruin the whole picture. Measure the deepest point of the device.
Consider an example calculation for a standard model. Let's assume the width of your refrigerator is 60 cm and the depth of the cabinet is 65 cm. Convert everything into meters to get the area in square meters: 0.6 m × 0.65 m = 0.39 m². This is the base area, but it does not take into account the necessary technological gaps.
Taking into account ventilation gaps in calculations
A refrigerator is a device that does not produce cold, but transfers heat from the inner chamber to the outside. For efficient operation of the heat exchanger, usually located on the rear wall or sides of the housing, a constant flow of air is required. If you ignore this requirement and place the equipment close to the walls, the area that the refrigerator actually “eats” will increase due to the required indentations.
Standard requirements for gaps vary depending on the model, but there are general rules. The side gaps are usually from 2 to 5 cm on each side, and the top - at least 10 cm. The back gap can be from 3 to 7 cm. All these centimeters must be taken into account when calculating the final niche area.
Let's add gaps to our previous example. If we add 2.5 cm on each side to the width of 60 cm (total 5 cm), then the required width of the niche will already be 65 cm. The depth will also increase by 5 cm for the rear gap. Thus, the actual area that needs to be reserved will be larger than the area of the housing itself.
⚠️ Attention: For built-in models, ventilation requirements are specified in the instructions separately. They often require the installation of ventilation ducts, which further increases the occupied space inside the cabinet.
Calculation of the useful volume of the chambers
Unlike the base area, the volume of the refrigerator is measured in liters and shows how much food you can fit in it. Manufacturers indicate the total volume, but it is the sum of the volumes of the refrigerator and freezer compartments. It is important to understand that the actual useful volume is always less than stated due to the presence of shelves, drawers, ledges and the air circulation system No Frost.
To approximately calculate the useful volume yourself, you can use the filling method. However, it is easier to use the geometric dimensions of the internal chambers. Measure the internal width, height and depth of each chamber (in decimeters) and multiply these values. 1 cubic decimeter is equal to 1 liter.
For example, if the internal width of the refrigerator compartment is 5 dm, the height is 10 dm and the depth is 4 dm, then the volume will be 5 × 10 × 4 = 200 liters. But this is a perfect cube. Reality makes adjustments: the compressor casing, the lighting shade and the convexities of the rear wall can “eat up” up to 15-20% of the volume.
Why is the volume decreasing?
The No Frost system requires the installation of an evaporator and a fan, which occupy the internal space. In addition, thick walls with improved insulation also reduce the useful displacement for the same external dimensions.
Comparative table of dimensions of various types of refrigerators
To make it easier for you to navigate the dimensions and occupied space, we have prepared a comparative table for the main types of refrigeration equipment. The data is given taking into account standard ventilation gaps.
| Refrigerator type | Width (cm) | Depth with gap (cm) | Occupied area (m²) | Features installations |
|---|---|---|---|---|
| Single-chamber | 60 | 70 | 0.42 | Requires minimal clearances |
| Double-chamber (euro) | 60 | 70 | 0.42 | Standard requirements |
| Side-by-Side | 90 | 75 | 0.68 | Wide opening required |
| Built-in | 54-56 | 60 | 0.33 | Depends on the furniture |
| Minibar | 45 | 50 | 0.23 | Can be placed close together |
As can be seen from the table, the area occupied by a full-size refrigerator Side-by-Sideis almost one and a half times more than the standard two-chamber model. This is critically important for owners of small-sized kitchens in old houses, where every centimeter counts.
Nuances of installation in a niche and set
Built-in equipment is a separate category, where calculating the area turns into jewelry work. Here the area of the refrigerator itself fades into the background, giving way to the area of the niche. An error of a couple of millimeters can cause the cabinet doors to become skewed or the sliding mechanism to jam.
When calculating a niche, it is necessary to take into account not only the dimensions of the cabinet, but also the thickness of the facades that will be hung on the refrigerator doors. The space for hinges and opening mechanisms is also important. Manufacturers usually provide templates for cutting, but you need to check them yourself.
Pay special attention to the basement area. In some models, ventilation is provided through the lower baseboard. If you brick this area or incorrectly calculate the height of the base, the refrigerator will overheat. The area of the ventilation hole in the base must be sufficient for free air flow.
☑️ Check before installation
⚠️ Attention: Specifications and installation requirements may vary depending on the specific series and year of manufacture. Always check the latest information in the official user manual or on the manufacturer's website before purchasing.
Frequently asked questions (FAQ)
Can the refrigerator be placed close to the wall?
It is strictly not recommended to place the refrigerator close to the wall without a gap. The minimum distance to the rear wall should be 3-5 cm to ensure air circulation and prevent overheating of the compressor.
How to find out the real volume if it is not written in the instructions?
The actual volume can be approximately calculated by measuring the internal dimensions of the chambers in decimeters (10 cm) and multiplying them. However, it is worth subtracting about 15-20% for shelves, drawers and the cooling system to get a realistic figure.
Does the kitchen area affect the choice of refrigerator power?
The kitchen area does not have a direct effect on the power, but it does affect heat transfer. In a small, poorly ventilated kitchen, the refrigerator will work harder because the air around it heats up faster. This can increase energy consumption.
Do you need to take into account the weight of the refrigerator when calculating the area?
Weight does not affect the area, but it does affect the load per square centimeter of the floor. For heavy models (over 100 kg), it is recommended to use distribution platforms under the legs so as not to damage the floor covering, especially if it is laminate or linoleum.
What to do if the refrigerator does not fit through the doorway?
In most cases, modern refrigerators can have doors removed. This reduces the depth and sometimes the width of the device, allowing it to be carried through a narrow opening. It is prohibited to remove the compressor or other technical components on your own.
