How much space does a fridge or a freezer really need

The figure printed on the spec sheet is the appliance. The figure you actually need is the hole it has to go into, and they are two different things. Anyone who confuses them finds out when the courier is already on the landing.

We at PortosEunostos downloaded the European EPREL registry on 31 October 2026 and kept the 47,224 domestic refrigerators and freezers with three declared, credible dimensions: 40,410 freestanding and 6,814 built-in. The most awkward number comes straight away: 44.50% of freestanding appliances are deeper than 600 mm, which means they stick out past a standard worktop. Among combi fridge-freezers alone the share rises to 53.69%.

The short answer

If the kitchen is a fitted one, there is only one route: you measure the niche and buy the appliance that fits it, never the other way round. There are two reference sizes, 1775 x 560 x 550 mm for the tall column and 820 x 600 x 550 for the under-counter slot, and they recur across almost the whole market. If instead the appliance is freestanding, no niche is declared at all: you can pick whatever volume you like, but you have to deal with a depth that reaches 660 mm and with at least 150 mm of air between two appliances side by side.

The three measurements that never match

Every Bosch spec sheet carries three sets of numbers and the retailer shows only one of them: the body is the bare appliance, the niche is the cabinet opening, the packaging is what has to get through your front door. We read nine of them. In millimetres, in the order height, width, depth:

• KIN86VSE0, built-in combi: body 1772 x 541 x 548, niche 1775 x 560 x 550, packed 1840 x 610 x 640.

• KIR81ADD0, built-in single door: body 1772 x 558 x 548, niche 1775 x 560 x 550, packed 1840 x 610 x 640.

• KUR21VFE0, built-in under-counter: body 820 x 598 x 548, niche 820 x 600 x 550, packed 890 x 655 x 625.

• KGN36NLEA, freestanding combi: body 1860 x 600 x 660, niche not declared, packed 1923 x 654 x 770.

• KGN39VIEB, freestanding combi: body 2030 x 600 x 660, niche not declared, packed 2090 x 660 x 760.

Two things stand out. On the built-in column the tolerance is 3 mm in height and 2 in width, and on the under-counter model the niche height is exactly the appliance height, 820 against 820: there is no room for a site error. And the four built-in columns we read declare the same packaging, 1840 x 610 x 640, despite having different bodies: the box follows the module, not the machine. The KGN39VIEB packed is 2.09 metres tall and 76 cm deep, so before ordering it measure the lift, not the kitchen.

Built-in: the niche is a grid, not a choice

Across the 6,814 built-in appliances the measurements cluster on very few values. 43.12% are between 1760 and 1790 mm tall, which is the 177 cm column, and 18.83% between 805 and 880, which is the under-counter slot. The width is exactly 540 mm in 47.89% of cases and falls between 535 and 560 in 76.17%. The depth sits between 540 and 550 mm in 86.65%.

This is where the most common catalogue misunderstanding is born. The KIN86VSE0 is sold as a 54 cm model and the KIR81ADD0 as a 56 cm one, yet they go into the same 560 mm niche: that figure is the body, not the opening. The KUR21VFE0 is sold as a 60 cm model and there the number really is the niche. Within the same catalogue the centimetres change meaning from one line to the next. Of the 740 OpportunityCommerce listings that state a width in the title, 60 cm accounts for only 29.46%, while 44.46% sits below 58.

Freestanding: there is no niche and the depth sticks out

In the spec sheets of the two freestanding combis the field for installation-recess dimensions is not empty: it is filled with a code that means not applicable. The manufacturer declares no niche, so the air around the appliance is something you have to add yourself. And air is needed, because depth is the real problem.

Among the 23,801 freestanding combis the median is 628 mm, 53.69% exceed 600 and 38.29% exceed 650. The result: only 49.66% fit inside a standard 60 x 60 cm kitchen run, against 86.88% of built-in appliances. On height, 30.22% sit between 180 and 200 cm and 7.37% go past two metres, where no wall unit will clear them.

Litres per square metre: what the floor really returns

In a kitchen the scarce resource is the square metre of floor, not the litre. We divided the declared volume by the occupied area, height band by height band, on freestanding appliances only: median litres and litres per square metre.

• Under 90 cm (under-table): 92 litres, 343.9 litres per square metre.

• 90 to 160 cm: 206 litres, 669.1.

• 160 to 200 cm: 326 to 331 litres, between 836.7 and 848.5.

• Over 200 cm: 367 litres, 946.3.

The reading is blunt: going up is almost free, going wide is not. The 4,770 appliances 85 cm wide or more declare a median 490 litres, the highest in the sample, but return 830.0 litres per square metre, less than a two-metre column sixty wide. A side by side gives you a third more litres and asks for twice the floor. It is the metric we opened when comparing chest or upright freezer, and here it applies to the whole cold section.

The clearances the manual imposes (and that move the energy bill)

Bosch user manuals set constraints no label reports, and on one point they even correct the spec sheet: the recommended niche depth is 560 mm and the permitted minimum is 550, while the sheets only state the minimum. The difference is not formal, because the manual writes, in so many words, that a shallower niche slightly increases energy consumption. Space is not only a fitting problem, it is a line on the bill, and how much it costs in euro we worked out in how much a refrigerator consumes in a year.

The other constraints: 30 mm from electric or gas hobs, 300 mm from oil or coal stoves, at least 150 mm between two appliances placed side by side or stacked, a room of 1 cubic metre for every 8 grams of refrigerant and a floor able to carry 70 kg.

PortosEunostos advice

What to check on the product. Take four measurements in this order: the clear height of the opening, the internal width between the cabinet sides, the usable depth from the wall to the front edge of the door and, above all, your front door with the appliance still packed. Then the hinge side and the cable length, 230 cm on Bosch columns. If you are buying built-in, insist on the line with the installation-recess dimensions: if it is missing, that appliance is not a built-in one.

How to judge the retailer. Ask whether delivery is to the floor and whether it includes unpacking: a two-metre combi weighs over 70 kg gross and turns badly in a corridor. And check that the listing carries the full model code, because between the KIN86VSE0 and the KIV86VSE0 what changes is No Frost and eight litres of freezer, not one letter. For the narrower formats prices sit side by side on SniffaPrezzi, while specs and availability are in the Refrigerators and Under-counter refrigerators categories on OpportunityCommerce: the KIN86VSE0 was listed at 906.30 euro and the KGN36NLEA at 725.50 euro on 31 October 2026.

The question to start from is not how many litres you want, but how many centimetres you have and of what kind. If there is a niche, the niche decides and the litres follow; if there is not, you gain freedom on volume and lose it on depth. Once the footprint is fixed, you pick the capacity with a 300, 400 or 500 litre refrigerator and the overall picture is in the right refrigerator is not the biggest one. The same reasoning applied to the dishwasher is in fully integrated, under-counter or freestanding.
