Quick answer

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.

Formula used

Net volume (m³) = (daily tonnes × storage days) ÷ density (t/m³) · Gross volume = net × 1.3

How to use this calculator
  1. 1Enter daily throughput in tonnes and how many days of stock you hold.
  2. 2Select the product type so the correct stacking density is applied.
  3. 3Choose the temperature class (chilled, frozen or blast) to set clearance factors.
  4. 4Read the gross m³, floor area and pallet positions, then export the figures into an RFQ.
Worked example

Worked example: sizing a 20 t/day frozen room

A frozen packaged-food operation receives 20 tonnes per day and needs 14 days of storage at −18 to −25 °C.

Inputs

Daily throughput
20 t/day
Storage days
14 days
Product density (frozen packaged)
400 kg/m³ net
Clear internal height
6.0 m (19.7 ft)

Calculation

Stored tonnage
20 t/day × 14 days = 280 t
Net product volume
280,000 kg ÷ 400 kg/m³ = 700 m³
Gross volume with 30% planning allowance
700 × 1.30 = 910 m³ (32,136 ft³)
Floor area at 6.0 m clear height
910 ÷ 6.0 ≈ 152 m² (1,636 ft²)
Euro-pallet volume equivalents
910 ÷ 2.2 ≈ 414

The live base-case model returns 910 m³ gross, approximately 152 m² of floor area and 414 Euro-pallet volume equivalents.

Benchmarks

Planning benchmarks — storage density by product

Product / regimeNet densityTypical gross m³ per 100 t
Palletised fruit & vegetables (0–4 °C)200–280 kg/m³800–1,100 m³
Cartoned meat & poultry (−18 °C)350–450 kg/m³500–650 m³
Frozen fish, block-frozen (−25 °C)400–500 kg/m³450–560 m³
Dairy & ready meals, mixed SKUs (2–6 °C)180–250 kg/m³900–1,250 m³
Pharma / vaccine cold store (2–8 °C)100–160 kg/m³1,400–2,200 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.

Calculation method

  1. stored mass = daily throughput × storage days
  2. net volume = stored mass ÷ product density
  3. gross volume = net volume × 1.30 × scenario factor
  4. floor area = gross volume ÷ clear height
  5. pallets ≈ gross volume ÷ 2.2 m³

Metric and imperial entries are converted to the same canonical metric values before calculation.

Worked example

A frozen packaged-food room receives 20 t/day and holds 14 days at 6 m clear height.

Inputs

  • • 20 t/day
  • • 14 storage days
  • • 400 kg/m³ product density
  • • 6 m / 19.7 ft clear height

Calculation

  • • 280,000 kg ÷ 400 = 700 m³ net
  • • 700 × 1.30 = 910 m³ gross
  • • 910 ÷ 6 ≈ 152 m² floor
  • • 910 ÷ 2.2 ≈ 414 Euro-pallet equivalents

Base-case output: 910 m³ (32,136 ft³), about 152 m² (1,636 ft²) and 414 pallet equivalents.

Limitations

  • • Density is a product-category assumption, not a measured stacking density.
  • • The 30% allowance is a planning factor; aisle, rack and evaporator layouts can require more space.
  • • Pallet count is a Euro-pallet volume equivalent, not a rack-layout design.

Cold room size

What can change the result
  • Stored product
  • Days of stock held
  • Clear ceiling height
  • Door openings per day
  • Operating schedule (hours/day)

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.

Cold room size calculator — how to use it

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.

What this cold room size calculator works out

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.

Who should use it

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.

Inputs required

Four numbers and one selection:

  • Daily intake in tonnes per day at peak, not average
  • Storage days — how long product stays before it leaves
  • Product type, which sets stacking density
  • Clear internal height available under the ceiling or evaporators
  • A planning scenario, to add headroom for growth or seasonal peaks

What the output means

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.

Assumptions and limitations

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.

Next step

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.

FAQ

How many pallets fit in a 100 m² cold room?

With 6 m clear height and single-deep racking, 100 m² typically holds 180–220 Euro pallets, or 240–280 with drive-in racking.

What safety margin should I use?

Add 25–30% to raw storage volume for aisles, racking, evaporators and cooling clearances.

Does product density really matter?

Yes. Frozen fish stacks denser than boxed produce. Using a generic density is a common cold-room capex mistake.

What inputs does the cold room size calculator need?

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.

What does the calculator give me, and what does it not?

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.

When should I use cold room sizing instead of a supplier's proposal?

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.

How do I size a store for several products, seasons or mixed chicken and turkey?

Use the detailed capacity-by-SKU mode: enter each product line with its own throughput, peak factor, days of cover and kg per pallet. Fresh poultry goes in the chilled zone and frozen poultry in the frozen zone; whole birds and parts get separate lines.

How do I turn the result into a refrigeration RFQ?

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.

Detailed mode · Capacity by SKU

Required capacity by SKU, season and turnover

Size cold storage from peak inventory, not averages: peak pallets = annual tonnes ÷ 365 × peak factor × days of cover × 1,000 ÷ net kg per pallet. Divide by target slot occupancy, add contingency, then convert positions to gross m³ using pallet footprint, slot height and storage density.

Enter each product line you will store. The planner converts peak-season inventory into pallets, pallet positions and gross chamber volume per temperature zone, then shows dock throughput and how sensitive the answer is. The example rows show a mixed chicken/turkey load — replace every value with your own figures.

Product line 1

Storage band: US labelling: raw poultry held at 0 °F (−18 °C) or below is labelled “frozen” or “previously frozen” (USDA FSIS).

Handling: Parts in cartons usually stack more uniformly than whole birds; enter the pallet weight from your own carton and pallet pattern.

Product line 2

Storage band: US labelling: raw poultry held at 0 °F (−18 °C) or below is labelled “frozen” or “previously frozen” (USDA FSIS).

Handling: Whole birds are bulky and irregular, so pallet weight and stacking differ from parts; model whole birds and parts as separate lines with their own seasonal peak.

Product line 3

Storage band: US labelling: “fresh” raw poultry is never held below 26 °F (−3.3 °C); refrigerated holding at 40 °F (4 °C) or below (USDA FSIS).

Handling: Short days of cover; keep raw poultry segregated from ready-to-eat lines; confirm the buyer's or retailer's own temperature specification.

How the capacity planner calculates

  1. Average daily flow = annual tonnes ÷ 365.
  2. Peak inventory (t) = average daily flow × peak factor × days of cover at peak. Turnover = 365 ÷ days of cover.
  3. Pallets at peak = peak inventory × 1,000 ÷ net kg per pallet, rounded up.
  4. Positions = pallets at peak ÷ target occupancy × (1 + contingency), per temperature zone. Line peaks are assumed to coincide, so staggered seasons make this conservative.
  5. Gross volume (m³) = positions × pallet footprint (m²) × slot height (m) ÷ storage density. Density is the share of the chamber that is pallet slots; the rest is aisles, docks and airflow.
  6. Dock throughput = peak daily flow spread over dock operating days, in pallets; outbound is modelled equal to inbound (steady state).

Example kg-per-pallet values and default assumptions are placeholders to edit, not product data. The planner does not size blast freezing, pre-cooling, anterooms, offices or plant rooms, and it is not an engineered layout. Compare its result with the quick tonnes-per-day estimate above: a large gap shows which assumption to confirm.

Meat and poultry refrigeration guide

US context: poultry in cold storage on 30 September 2026

USDA NASS reports end-of-month stocks held in about 750 US public and private warehouses cooled to 50 °F or lower. These are US-only inventories: they do not measure warehouse capacity, prices or demand in any other country, and they are not used in the calculation above. They show why sizing should use your own peak rather than an average: stocks move month to month.

Buyer RFQ checklist for cold storage capacity

  1. Product list by SKU or category, with storage temperature specification for each (your own or your customer's).
  2. Annual throughput, monthly profile or peak factor, and days of cover at peak — from sales or harvest records, not averages.
  3. Pallet type and footprint, net kg per pallet, load height and stacking limits per product.
  4. Target slot occupancy, contingency and any planned growth phases.
  5. Inbound/outbound pallets per day at peak, dock hours, number of shifts and vehicle types (reefer trailer, container).
  6. Segregation rules: raw vs ready-to-eat, allergens, organic or halal lots, customer-owned stock, quarantine and returns.
  7. Whether any product must be frozen or blast-chilled on site (a separate process stage, not sized by this planner).
  8. Traceability and temperature-record requirements (lot/batch, FEFO, monitoring and alarm duty).
  9. Site country, design ambient, power availability and any refrigerant or safety restrictions.
  10. Ask suppliers to state their own positions, volume and refrigeration duty against these inputs so offers are comparable.

From calculated volume to a comparable quote

A volume figure is the starting point, not the brief. These are the answers suppliers need before your cold-room project can be priced on a like-for-like basis.

Data a supplier needs before it can price your project

  • Stored product, packaging and unit load (pallet, crate, drum, carton)
  • Temperature band and allowed tolerance, plus any pull-down or freezing duty
  • Usable volume in m³ or pallet positions, and clear internal height
  • Daily throughput in and out, door regime and peak-season profile
  • Site ambient design conditions, altitude and available floor area
  • Available electrical supply, grid reliability and backup power already on site
  • Target operational date and any phasing

Project scope to fix before you compare bids

  • Civils, slab, floor insulation and drainage — included or by others
  • Envelope: panels, doors, air curtains, dock seals and protection
  • Refrigeration plant, refrigerant choice, condensing and heat rejection
  • Controls, BMS integration, monitoring, alarms and data retention
  • Installation, supervision, commissioning and performance test conditions
  • Spares, training, warranty terms and service response expectation
  • Freight, insurance, duties, clearance and inland haulage responsibility

Energy and TCO assumptions to state explicitly

  • Electricity tariff, demand charges and expected annual escalation
  • Operating hours, seasonal load profile and standby periods
  • Outage hours per year and the cost of running backup generation
  • Defrost strategy, door losses and infiltration at real door traffic
  • Maintenance, refrigerant handling and inspection costs per year
  • Expected life, refurbishment point and residual value assumption
  • Whether quoted energy figures are calculated, measured or catalogue values

How to qualify a supplier or contractor

  • Comparable reference projects at your temperature band, scale and climate
  • Who performs the engineering, and who performs site installation
  • Local or regional service presence and realistic response time
  • Spare-parts availability and lead times after hand-over
  • Financial standing and the payment and retention structure proposed
  • Clarity of exclusions — the exclusions list tells you more than the price
