For commercial and industrial refrigeration projects (cold rooms, cold stores, process cooling) — not household fridges, home freezers or appliance repair. Results are planning estimates, not engineering design or safety advice; a qualified refrigeration engineer must confirm sizing before purchase.
How big does your cold room need to be? This free cold room size calculator turns three numbers — daily throughput in tonnes, storage days and product type — into the gross volume in m³, floor area in m² and pallet capacity your project requires. Results include a 30% design margin and are ready to paste straight into a cold storage RFQ. No sign-up, no email gate.

Cold room size is derived from daily throughput × storage days ÷ product stacking density, plus 25–35% for aisles, pallet clearance and evaporator space. As a working rule, 1 tonne of palletised chilled food needs roughly 4–5 m³ of gross room volume, and a standard 1.2 × 1.0 m euro pallet stacked 1.8 m occupies about 2.2 m³.
Net volume (m³) = (daily tonnes × storage days) ÷ density (t/m³) · Gross volume = net × 1.3

A frozen packaged-food operation receives 20 tonnes per day and needs 14 days of storage at −18 to −25 °C.
The live base-case model returns 910 m³ gross, approximately 152 m² of floor area and 414 Euro-pallet volume equivalents.
| Product / regime | Net density | Typical gross m³ per 100 t |
|---|---|---|
| Palletised fruit & vegetables (0–4 °C) | 200–280 kg/m³ | 800–1,100 m³ |
| Cartoned meat & poultry (−18 °C) | 350–450 kg/m³ | 500–650 m³ |
| Frozen fish, block-frozen (−25 °C) | 400–500 kg/m³ | 450–560 m³ |
| Dairy & ready meals, mixed SKUs (2–6 °C) | 180–250 kg/m³ | 900–1,250 m³ |
| Pharma / vaccine cold store (2–8 °C) | 100–160 kg/m³ | 1,400–2,200 m³ |
Utilisation of 0.40–0.50 covers aisles, evaporator clearance and picking faces. Automated (ASRS) freezers reach 0.60–0.70 and cut floor area by roughly a third.
Metric and imperial entries are converted to the same canonical metric values before calculation.

Cold room size
Limitations
This is a preliminary planning estimate based on the assumptions you entered, not a refrigeration-engineering design, a certified load calculation or a quotation. Before equipment is ordered, cooling load, refrigerant selection, safety and system design should be verified by a qualified refrigeration engineer.
Square metres are not a cooling load: a cold room is sized around the heat that must be removed, not floor area alone.
Maintaining frozen product and freezing warm product are different refrigeration duties, and they produce very different system sizes.
Two refrigeration quotations are not comparable until their design assumptions are comparable — and a low equipment price can hide a high lifetime energy cost.
Next procurement step
Use this result as the starting point for a ColdMatch project request. Every request is reviewed manually by our procurement desk before any manufacturer or contractor is approached — buyers are never connected automatically to listed suppliers.
Turn this calculation into an RFQResearch matching suppliers by refrigerant, capacity and countryAI agents may use ColdMatch calculators to structure preliminary cold-storage requirements and RFQs. Cooling-load, refrigerant, safety and system-design assumptions should be exposed as assumptions and verified before final engineering.
A cold room is sized from peak daily intake multiplied by storage days, converted through product stacking density into net volume, then uplifted for aisles, airflow and evaporator clearance to give the gross internal volume. Divide that by the clear height available and you have the floor area to design around.
It converts daily intake and storage duration into the internal volume a cold room needs: gross m³ including circulation and evaporator space, net product volume, floor area at your chosen clear height, and an indicative pallet-position count. That is the starting point of cold storage sizing and refrigeration capacity planning — the figure suppliers need before they can size plant or quote a building.
Buyers, processors, exporters, distributors, 3PL operators and project developers scoping a new cold room, a frozen store or an extension, and anyone about to request quotations who does not yet have engineered cold room dimensions.
Four numbers and one selection:
Gross volume is the internal room volume to design around, already uplifted above net product volume for aisles, pallet gaps, airflow and evaporator clearance. Floor area is that volume divided by your clear height. Pallet positions are an indicative count at standard euro-pallet occupancy — real racking layouts vary with aisle width, racking type and door positions.
Densities are typical planning values per product group, not measured values for your packaging. The calculator sizes storage volume only: it does not calculate cooling load, compressor duty, insulation thickness, energy consumption or price. Results are indicative and subject to engineering review — use them to structure a brief, not to order equipment.
Once the volume is fixed, work out the cooling load and the budget range, then turn both into a written brief. Planning an industrial cold-chain project? Send the project location, required capacity, product, operating temperature and target timeline so the requirement can be reviewed.
With 6 m clear height and single-deep racking, 100 m² typically holds 180–220 Euro pallets, or 240–280 with drive-in racking.
Add 25–30% to raw storage volume for aisles, racking, evaporators and cooling clearances.
Yes. Frozen fish stacks denser than boxed produce. Using a generic density is a common cold-room capex mistake.
Four things: daily throughput in tonnes, how many days of stock you hold, the product type (which sets storage density) and the clear internal height you can build to. Everything else — gross volume, floor area and pallet positions — is derived from those.
It returns required storage volume in m³, indicative floor area and pallet positions with an allowance for aisles, racking and evaporator clearance. It does not size the refrigeration plant: for cooling duty in kW use the refrigeration load calculator, and for running cost the electricity cost calculator.
Before you request quotations. Fixing capacity, throughput and clear height yourself means every supplier prices the same facility, so the offers are comparable. Sizing supplied by one vendor tends to reflect that vendor's standard product rather than your operation.
Take the volume, pallet positions and clear height from the result, add temperature setpoint, product entry temperature, daily throughput and site ambient conditions, then use the RFQ builder. ColdMatch reviews the brief before any supplier or EPC introduction.

Use this calculator to turn product volume and pallet count into usable floor area and room volume. The figure is a starting envelope: aisle layout, racking type, door positions and expansion allowance change the final footprint.
Commercial projects from USD 250,000: ColdMatch reviews your brief and introduces suitable independent suppliers. Results here are planning estimates, not quotations.
No. It is a planning estimate from your own inputs and the published method on this page. Supplier prices depend on site survey, specification, freight, duties and local installation, so use the result to set scope and budget expectations, then compare reviewed supplier proposals.
Suppliers often add circulation space, door clearances, evaporator space and expansion. Ask each one to state net pallet positions so proposals compare like-for-like.
Size the envelope and slab for the growth you can justify, and phase refrigeration if needed. Adding insulated space later usually costs more than building it once.
