How to calculate the facades for a built-in refrigerator: formulas, diagrams and life hacks from the experts

A built-in refrigerator is not only a matter of saving space, but also a delicate balance between functionality and kitchen design. An error in the calculation of the facades on only 2-3 mm can lead to the door touching the furniture, closing poorly, or, conversely, leaving gaps through which the cold will escape. And redoing facades after installation is a waste of time and money.

In this article you will find step-by-step instructions taking into account the characteristics of different brands (Liebherr, Bosch, Electrolux), ready-made formulas for calculation, and also unique compatibility tables for facades and built-in refrigerators —they are not in the standard manufacturers’ instructions. We will look at how to avoid typical mistakes (for example, ignoring ventilation gaps) and what to do if the refrigerator is installed in a niche with non-standard dimensions.

Let us warn you right away: if you plan to build in a refrigerator to a ready-made kitchen, and not to order, be prepared for the fact that furniture adjustments may be required. Manufacturers of built-in equipment often indicate minimum niche sizes, but in reality additional millimeters are needed for comfortable operation.

1. What data is needed to calculate facades?

Before taking up the tape measure, collect all the necessary information. Without it, even the most accurate formula will give an erroneous result. Here's what you'll need:

• 📏 Dimensions of the refrigerator (width × height × depth) - take it from the technical data sheet or measure it yourself. Please note that for some models (for example, Siemens iQ700), the depth of the case and the depth including the door may differ by 5–7 cm.
• 🔧 Type of facade fastening: overhead (screwed on top) or integrated (inserted into grooves). This affects the thickness of the material and the method of calculation.
• 🪵 Facade material: MDF, solid wood, plastic or aluminum. For example, facades made of solid oak 18 mm thick require a different approach than thin plastic panels (8–10 mm).
• 🔄 Direction of door opening (left/right) - the location of the hinges and, accordingly, the dimensions of the facade depend on this.
• 📄 Drawing or diagram of the kitchen unit (if available). Without it, it is difficult to take into account the location of adjacent cabinets, hoods or countertops.

Pay special attention ventilation gaps. Manufacturers of built-in equipment (for example, Liebherr) require mandatory indents:

• ⬆️ Top: minimum 20–30 mm for air circulation (for some models up to 50 mm!).
• ⬇️ Bottom: 10–15 mm (sometimes 5 mm is enough if the niche has adjustable legs).
• ⬅️➡️ On the sides: 5–10 mm on each side (for models with a capacitor on the back wall).

⚠️ Attention: If the refrigerator is installed in a niche made of LDSP or MDF, keep in mind that the material can “play” when humidity changes. It is better to make gaps 1-2 mm larger than the manufacturer recommends.

2. Formulas for calculating facades: from theory to practice

The main task is to determine apparent width and height of the facadewhich will cover the front of the refrigerator. To do this, we use two key formulas:

Formula 1: Calculation of the width of the facade

If the refrigerator is built into a niche without side walls (open installation), the width of the facade is calculated as follows:

Facade width = Refrigerator width + 2 × (Front thickness + Hinge gap)

Example for Bosch KIV38X20 (width 54 cm, front thickness 16 mm, hinge gap 3 mm):

540 mm + 2 × (16 mm + 3 mm) = 540 + 38 = 578 mm

Formula 2: Calculation of the height of the facade

Here we take into account that the facade should overlap the height of the refrigerator, but not rest against the countertop or plinth:

Facade height = Refrigerator height + Upper gap + Bottom gap - Tabletop thickness (if the facade rests on it)

For model Liebherr ICBN 3366 (height 177.2 cm, upper gap 30 mm, bottom 10 mm, countertop 28 mm):

1772 mm + 30 mm + 10 mm – 28 mm = 1784 mm

If the refrigerator is built into a box made of furniture panels, the formulas are simplified - the facade must match the dimensions of the box. But here it is important to take into account:

• 🔹 The thickness of the furniture walls (usually 16–18 mm for LDSP).
• 🔹 Niche depth —the refrigerator should not rest against the back wall (minimum gap 50 mm for models with a fan).

3. Table of standard facade sizes for popular models

To save time, we have collected data on the most common built-in refrigerators. Please note: the dimensions of the facades may vary depending on model series and year of manufacture. Always check the technical data sheet!

If your model is not in the table, use universal rule:

• 📌 For refrigerators with a width 54–56 cm facade is usually made 57–60 cm.
• 📌 For models with a width 60 cm — facade 62–65 cm.
• 📌 The height of the facade is always 10–30 mm more height of the refrigerator (depending on the gaps).

⚠️ Attention: For refrigerators with French door (for example, Samsung RB38T602CS9) the calculation of facades is more complicated - it is necessary to take into account two separate doors. Here it is better to order facades from a furniture manufacturer linked to a specific one. models.

4. Typical errors in calculations and how to avoid them

Even experienced craftsmen sometimes make mistakes that lead to problems during operation. Here are the most. common:

Error 1: Ignoring gaps for ventilation

Many people forget that the refrigerator needs air flow. If you do not leave gaps:

• 🔥 The compressor will overheat, which will shorten its service life.
• 💨 Condensation will accumulate on the back wall.
• ❄️ Ice may form in the freezer due to unstable temperature.

Solution: always add minimum 20 mm on top and 5–10 mm on the sides (even if the instructions say otherwise).

Error 2: Not taking into account the thickness hinges

Hinges for facades come in different types:

• 🔗 Invoice (attached from above) - add 15-20 mm to the width.
• 🔗 Built-in (recessed into the facade) - require milling and increase the thickness material.
• 🔗 With a closer —can move the facade 5–10 mm forward.

If you do not take this nuance into account, the door will not close tightly or, conversely, cling to the furniture.

Error 3: Calculation "butt"

Some try to save space and make facades according the exact size of the refrigerator. This leads to:

• 🚪 The door touching adjacent cabinets when opening.
• 🔨 Difficulties during dismantling (the facade can “get stuck” in a niche).
• 📉 Deterioration of thermal insulation due to a tight fit.

Solution: always add minimum 5 mm to the side for free movement.

5. Features of calculation for non-standard niches

What to do if the refrigerator needs to be built into a niche with non-standard sizes? For example, when the width of the box is 60 cm and the refrigerator is 55 cm, or when the height of the niche is limited by wall cabinets. Let's consider two scenarios:

Scenario 1: The niche is wider than the refrigerator

If the difference is up to 3–4 cm, you can:

• 🔧 Use additional side panels (from the same material as the facade).
• 🔧 Install decorative overlays (for example, aluminum or plastic).
• 🔧 Move the refrigerator to one of the walls of the niche, and close the remaining space with a false panel.

If the difference is greater 5 cm, it is better to redo the niche or choose a refrigerator according size.

Scenario 2: The niche is narrower than the refrigerator

There are fewer options here:

• 🔨 Expand the niche (if this is possible without damaging the furniture).
• 🔄 Choose a model with smaller width (for example, instead of 55 cm, take 50 cm).
• 📏 Make the facade narrower than the refrigerator, but then the door will protrude beyond the box.

For niches with non-standard height (for example, only 170 cm remains under the countertop, and the refrigerator is 177 cm), the solutions are:

• 🔧 Reduce the height of the base or remove it completely.
• 🔧 Use a refrigerator with top ventilation (requires less space on top).
• 🔧 Order a facade with cutout for the countertop (if the difference is up to 5 cm).

What to do if the refrigerator does not fit into the niche in depth?

If the depth of the niche is less than the depth of the refrigerator (including the facade), there are two options:

1. Pull the refrigerator forward —the facade will protrude beyond the box. It's ugly, but sometimes the only way out is.

2. Use a refrigerator with a flat back wall (for example, Liebherr ICBS 3366). Such models take up 3–5 cm less space, since the condenser is located on the sides.

6. Step-by-step instructions: how to calculate the facade yourself

If you decide to make calculations without the help of a wizard, follow this algorithm:

1. Step 1. Measure the refrigerator.

   Use metal tape measure (plastic may give an error). Measure:

   • 📏 Width along the body (excluding the door).
   • 📏 Height from the floor to the top edge.
   • 📏 Depth (from the front edge to back wall).

   Repeat the measurements 2-3 times - the body may not be perfectly smooth.

2. Step 2. Determine the type of facade.

   Check with the furniture manufacturer:

   • 🔹 Material thickness (standard: 16–18 mm for MDF, 8–10 mm for plastic).
   • 🔹 Type of hinges (overhead or built-in).
   • 🔹 Presence of a closer (adds 5–10 mm to the depth).
3. Step 3. Calculate the dimensions facade.

   Use the formulas from Section 2, adding:

   • ➕ Ventilation gaps (see instructions for the refrigerator).
   • ➕ Thickness hinges and closer.
   • ➕ Tolerance for the “play” of the material (1–2 mm).

Step 4. Check compatibility with furniture.

Make sure that:

• 🔹 The facade will not rest against neighboring cabinets when opened.
• 🔹 The door opens 90° without obstacles.
• 🔹 The ventilation holes are not blocked.
• Step 5. Make a drawing.

  Draw a diagram indicating all dimensions and indentation This will help the furniture maker avoid mistakes.

7. Where to order facades: comparison of options

Facades for a built-in refrigerator can be made in several ways. The choice depends on the budget, materials and completion time:

Production option	Cost (for 1 facade)	Completion time	Pros	Cons
Order from the kitchen manufacturer	from 5,000 ₽	7–14 days	Perfect match with furniture, guarantee	Expensive, long
Furniture workshop	from 3,000 ₽	5–10 days	Flexible prices, you can choose the material	Quality depends on the craftsman
Independent production (from MDF/plastic)	from 1,500 ₽	1–3 days	Cheap, fast	Requires skills to work with tool
Ready facades (for example, from Hettich or Blum)	from 4,000 ₽	3–7 days	Easy installation, reliable hinges	Limited selection of sizes

If you choose self-production, prepare:

• 🔨 Jigsaw or circular saw.
• 📐 Square and tape measure.
• 🔧 Router for grooves (if the hinges are built-in).
• 🎨 Paint or film for finishing (if the facade is not laminated).

⚠️ Attention: When When ordering facades in the workshop, check whether the price includes milling for hinges And holes for fasteners. Often this is paid separately (from 500 to 1,500 ₽).

8. Frequently asked questions about calculating facades

Is it possible to use facades from an old refrigerator for a new model?

Theoretically, it is possible, but only if:

• 🔹 The dimensions of the refrigerators are the same up to a millimeter.
• 🔹 The type of facade fastening is the same (overlay/built-in).
• 🔹 The hinges are suitable in location and size.

In practice, this is unlikely - even from the same manufacturer, models from different series may differ. It is better to order new facades.

How to calculate the facade for a refrigerator with a French Door?

For models with two doors (for example, Samsung RB38T602CS9you need to:

1. Calculate the width of each doors separately (divide the total width of the refrigerator by 2).
2. Add gaps between the doors (usually 2-3 mm).
3. Keep in mind that hinges for French Doors are often asymmetrical -top and bottom may differ.

It is better to order such facades from a furniture manufacturer with reference to a specific model.

What to do if the facade is larger/smaller than the required size?

If the facade larger:

• 🔹 Can be trimmed (if the material allows).
• 🔹 Use decorative overlays to mask the gap.

If the facade smaller:

• 🔹 Add additions (strips of the same material).
• 🔹 Remake the facade (if the difference is more than 5 mm).

Do I need to take into account the handle of the refrigerator when calculating the facade?

Yes, if the handle built-in (for example, at Liebherr or Siemens). In this case:

• 🔹 The facade must have a cutout for the handle.
• 🔹 Or the handle must be facade). removable (it is fixed after installing the facade).

If the handle invoice (like most Bosch), it can be mounted on top of the facade.

How calculate the front for a refrigerator with an ice maker?

Models with an ice maker (for example, Liebherr ICN 3366) require:

• 🔹 Additional space right (for the water supply tube).
• 🔹 Cutout in the facade under dispenser (if it is remote).
• 🔹 Accounting weight — the facade must be stronger (18 mm MDF is recommended).

It is better to order the facade from the manufacturer indicating the refrigerator model.
