🌍 Introduction: CBM Matters More Than Ever in 2026

Whether you’re shipping a classic car, relocating household goods, or loading both into a single container, CBM (Cubic Meter Measurement) determines everything — pricing, container size, loading strategy, and customs documentation. In 2026, with rising freight costs and stricter port regulations, understanding CBM is essential for planning an efficient and cost‑effective shipment.

This guide breaks down exactly how to calculate CBM for cars, furniture, boxes, and combined shipments, using simple formulas and real‑world examples.

📦 What Is CBM? (2026 Definition)

CBM (Cubic Meter) is the standard unit used in international shipping to measure volume.

CBM Formula

$CBM = Length (m) \times Width (m) \times Height (m)$

CBM determines:

How much fits in a container
Whether you need a 20‑ft or 40‑ft
Pricing for LCL (shared container) shipments
How to load cars + household goods together

📐 CBM Conversion Chart (Quick Reference)

Measurement	Conversion
1 meter	3.28 feet
1 cubic meter	35.3 cubic feet
Inches → meters	÷ 39.37
Feet → meters	÷ 3.28

🚗 CBM for Cars (2026 Examples)

Below are average CBM values for common vehicle types.

Vehicle Type	Example Models	Approx. CBM
Compact Car	Honda Civic, VW Golf	10–12 CBM
Sedan	BMW 5‑Series, Mercedes E‑Class	12–14 CBM
Classic Muscle Car	Mustang, Camaro, Chevelle	13–15 CBM
SUV	Range Rover, Toyota 4Runner	14–18 CBM
Pickup Truck	F‑150, Silverado	18–22 CBM

Why CBM for Cars Varies

Length (classic cars often longer)
Height (lifted trucks increase CBM)
Width (widebody or modified vehicles)

📦 CBM for Household Goods (2026 Guide)

Boxes

Box Size	Dimensions	CBM
Small	16×12×12 in	0.05 CBM
Medium	18×18×16 in	0.08 CBM
Large	24×18×18 in	0.12 CBM
XL	24×24×24 in	0.16 CBM

Furniture

Item	Average CBM
Sofa (3‑seat)	1.5–2.5 CBM
Queen mattress	1.0–1.3 CBM
Dining table	1.0–1.8 CBM
Dresser	0.8–1.2 CBM
Office desk	0.5–1.0 CBM

Appliances

Appliance	CBM
Refrigerator	1.0–1.5 CBM
Washer/Dryer	0.8–1.2 CBM
TV (boxed)	0.1–0.3 CBM

🚚 How Much Fits in a 20‑ft vs 40‑ft Container?

20‑ft Container

Max CBM: ~33 CBM
Fits:
- 1 car OR
- 1 car + 5–10 small boxes
- Small apartment (partial move)

40‑ft Container

Max CBM: ~67 CBM
Fits:
- 1 car + full household move
- 2 cars
- 1 car + motorcycle + furniture
- 1 car + 20–40 boxes + furniture

This is the most common choice for classic car + household goods shipments.

🧮 How to Calculate CBM for Combined Shipments (Car + Household Goods)

Step 1: Calculate the car’s CBM

Example: Classic Mustang = 14 CBM

Step 2: Add household goods

Example:

10 medium boxes = 0.8 CBM
Sofa = 2.0 CBM
Mattress = 1.2 CBM
Desk = 0.8 CBM

Total household goods = 4.8 CBM

Step 3: Add both together

$14 + 4.8 = 18.8 CBM$

Step 4: Choose container

20‑ft container max: 33 CBM → Fits easily
40‑ft container max: 67 CBM → More space for furniture

⚠️ Common CBM Mistakes to Avoid in 2026

Measuring in inches instead of meters
Forgetting to include packaging/crating
Not accounting for irregular shapes
Overloading a 20‑ft container
Assuming a car fits without measuring height
Forgetting that some countries restrict mixed loads
