Total volume of the refrigerator - what does it mean and how not to make a mistake with the choice?

When you stand in front of a display case with refrigerators or leaf through the catalog of an online store, one of the first parameters that people pay attention to is total volume. But what exactly is hidden behind this number? Why can two models with the same “total” displacement fit different amounts of food inside? And how not to overpay for unnecessary cubic meters or, conversely, not be left without space for food?

In this article we will analyze in detail what total volume of the refrigeratoris, how to distinguish it from usable volume, what standards exist for families of different sizes and how manufacturers sometimes manipulate numbers. You will also learn why the volume of the freezer can “eat up” up to 30% of the declared total capacity —and how to take it into account when purchasing. And at the end, a checklist of 5 steps awaits you, which will help you choose a refrigerator by volume without errors.

Total volume vs useful volume: what is the difference?

Many buyers confuse these two concepts, and some sellers specifically exploit this confusion. Let's figure it out:

Total volume is total internal volume all refrigerator compartments, measured in liters. This includes:

• 🧊 Freezer compartment (if there is one)
• 🥦 Refrigerator compartment (main compartment)
• 🥤 Door shelves and compartments
• 🍎 Boxes for fruits/vegetables (if built-in)
• 🥩 Freshness zone (if provided)

Useful volume is the space that is can actually be used for storing food. It is always less than the total, because:

• ❄️ Part of the volume is occupied internal walls, evaporators, fans (in models with No Frost)
• 📦 Shelves and containers are thick and do not allow filling the space 100%
• 🔄 In some models, part of the volume is “eaten up” by the air circulation system

For example, a refrigerator with total volume 350 liters may have usable volume 280–300 liters. The difference of 50–70 liters is not a deception, but a technical necessity. However, some brands (especially little-known ones) may inflate the numbers, indicating the total volume in the characteristics, when in fact we are talking about the amount gross (including packaging or external dimensions).

How the volume of a refrigerator is measured: standards and tricks of manufacturers

The volume of a refrigerator is measured according to strict standards, but there are nuances here too. GOST 16317-87, which determines the calculation method. According to it:

1. Measured internal volume all chambers (excluding wall thickness).
2. Takes into account all compartmentsincluding door shelves and drawers.
3. The volume is rounded to whole liters.

However, manufacturers can use different approaches:

• 📏 European brands (Liebherr, Bosch, Siemens) usually indicate useful volume or make a note “general/useful”.
• 🏭 Asian brands (Samsung, LG, Haier) more often operate total volumethat may be misleading.
• 🤫 Little-known brands sometimes indicate gross volume (including packaging) or rounded up.

To avoid being scammed, check:

For example, a refrigerator Samsung RB30A3200SA has total volume 311 l, but a useful one is about 270 l. And the model Liebherr CNef 4315 with the same total volume offers 290 l useful space due to more thoughtful ergonomics.

How many liters are needed per person: table of standards

One of the key questions when choosing a refrigerator is how many liters are required per person? There is no universal answer, but there are recommendations:

Important take into account not only the number of people, but also lifestyle:

• 🏠 If you often cook at home and store semi-finished products, take the model 20–30% more standard norm.
• 🍽️ Those who like defrosting and making large purchases (for example, grilled meat) will need a freezer with a volume of 100 l or more.
• 🏙️ In a small kitchen it is better to choose narrow but tall a refrigerator (for example ATLANT XM 4021-000 with a volume of 350 l and a width of 60 cm).

⚠️ Attention: If the family has small children, add another 50–70 liters to calculate. Baby food, juices, purees and emergency supplies take up a lot of space.

How is the volume distributed between the chambers?

It is equally important how the total volume is divided between the refrigerator and freezer compartments. There are three main options:

1. 70/30 - the classic ratio (70% refrigerator, 30% freezer). Suitable for most families.
2. 60/40 —enlarged freezer. It’s optimal if you freeze a lot of food (berries, mushrooms, meat).
3. 80/20 —minimum freezer. Suitable for those who rarely use freezing (for example, in small apartments).

Examples of distribution in popular models:

• 🍏 ATLANT XM 4021-000: 245 l (refrigerator) + 84 l (freezer) → 74/26
• ❄️ Samsung RB37A5200SA: 233 l + 116 l → 67/33
• 🥩 Liebherr CBN 4815: 300 l + 154 l → 66/34 (ideal for freezing lovers)

If you often buy food in bulk or preparing for a week ahead, pay attention to models with freshness zones (for example, Sharp SJ-FX520V-SL). They take up part of the total volume, but allow you to store fresh vegetables, meat and fish longer without freezing.

What is a freshness zone and why is it needed?

The freshness zone is a compartment with a temperature of about 0°C and high humidity. Food does not freeze in it, but also does not deteriorate as quickly as in the main chamber. For example, meat in such a zone is stored for up to 7 days (versus 2-3 in a regular refrigerator), and greens remain fresh for up to 10 days.

How do dimensions affect volume?

Many people mistakenly think that the larger the refrigerator, the greater its volume. In fact, this is not always the case. Here's what's really important:

• 📏 Height: A narrow but high refrigerator (180–200 cm) can have a volume of 300–350 liters, while a wide but low one (150 cm) can only have 250 liters.
• 🔳 Depth: Standard depth is 60 cm, but there are models with increased depth (70–80 cm)that hold 20–30% more.
• 🔄 Type of chamber arrangement:
  • Single chamber —refrigerator compartment only (volume up to 200 l).
  • Two-chamber —refrigerator + freezer (200–500 l).
  • Side-by-Side - two chambers side by side (400–800 l).
  • Multi-Door - 3-4 chambers (from 500 l, for example, Samsung RF23HCEDBSR).

Example: refrigerator Bosch KAN92VI30R has dimensions 70×66×176 cm and volume 366 l, while Indesit DF 5200 W with 60×64×200 cm offers only 325 l. The difference is 40 liters with similar external dimensions!

⚠️ Attention: Built-in refrigerators (for example, Electrolux EEN 91840 L) have a smaller volume with the same dimensions due to the need for a ventilation gap.

Refrigerator volume and energy consumption: is there a connection?

Many are afraid that a large refrigerator will “eat” a lot of electricity. volume is not the main factor in energy consumption. Much more important:

• 🌡️ Energy efficiency class (from A+++ to D). Modern class models consume 50% less. than A+++ consume 50% less than A+.
• ❄️ Type of defrosting:
  • No Frost - consumes 10-15% more, but does not require manual defrosting.
  • Drip system - more economical, but needs defrosting 1-2 times a year.
• 🔄 Frequency of opening doors: The more often you look into the refrigerator, the more it consumes.
• 🌍 Climate class (for example, SN-T for hot climates it consumes 20% more).

For comparison:

As you can see, Liebherr with a volume of 373 liters consumes even less than ATLANT with 345 liters. Therefore, when choosing, do not be guided by. per displacement, and energy efficiency class and defrost type.

Top 5 mistakes when choosing a refrigerator by volume

Even experienced buyers sometimes make mistakes. Here are the most common mistakes:

1. Buying in reserve. A 500-liter refrigerator for a family of 2 people is not rational. data-i="239">Buying in reserve
• 💰 Overpaying for electricity (larger volume = more air for cooling).
• 🦠 Development of bacteria (condensation accumulates in empty compartments).

2. Ignoring the freezer compartmentIf you do not freeze food, why pay for it. extra 100 liters of freezer? Is it better to choose a model with the ratio 80/20.
3. Ignoring the height. A refrigerator with a height of 2 m may not fit under wall cabinets or look bulky in a small kitchen.
4. Trust only in numbers. Always look at ergonomics: the depth of the shelves, the possibility of adjustment, the presence of drawers.
5. Purchase without measurementsMake sure that the refrigerator will fit through the doorway and can be transported. staircase (if you do not live on the first floor).

To avoid these mistakes, use our checklist:

FAQ: Answers to frequently asked questions

❓ How to find out the actual useful volume of the refrigerator if only the total volume is indicated in the specifications?

Subtract 15-20% from the total volume For example, if indicated. 350 l, the useful volume will be about 280–300 l. For accuracy, look for owner reviews or video reviews with measurements of the internal space.

❓ Is it possible to increase the useful volume of the refrigerator?

Yes, in several ways:

• 📦 Use organizers for shelves (for example, plastic containers).
• 🧊 Replace standard drawers with pull-out (if the design allows).
• 🧲 Use magnetic holders for bottles on the door.
• ❄️ Defrost the freezer regularly (ice “eats” up to 10% of the volume).

❓ What volume of refrigerator is needed for a family of 4 people if we like to cook and freeze?

The optimal option is 350–450 l with a chamber ratio 60/40 (for example, Liebherr CBNes 5755 or Samsung RF56A9671SG). Pay attention to models with:

• 🥩 Freshness zone (for meat/fish).
• 🍦 Quick freezing (Super Freeze).
• 🔄 System No Frost (so as not to waste time on defrosting).

❓ Why is there so little space for food in Side-by-Side refrigerators with a large total volume?

In models Side-by-Side part of the volume is occupied by:

• 🔌 Two compressors (if the model is two-compressor).
• 🌬️ Air exchange system (especially in No Frost).
• 🚪 Thickened walls for better insulation.

In addition, in such refrigerators many “dead zones” (for example, the space between the shelves and the door). To avoid mistakes, look for models with adjustable shelves (for example, Samsung RS6HA8891SL).

❓ What is the volume of the freezer? Are chambers needed for winter supplies?

For supplies for 3–6 months, the optimal volume is 100–150 l. Approximate norms:

• 🍓 For berries (10 kg) - 30–40 l.
• 🥩 For meat (20 kg) - 50-60 l.
• 🐟 For fish (5 kg) - 15-20 l.
• 🍅 For vegetables/fruits (15 kg) - 40-50 l.

If there is not enough space, consider a separate freezer (for example, ATLANT M 7204-003 200 l).
