What is Purolator Dimensional Weight?
The concept of Purolator dimensional weight, often referred to as volumetric weight, is a crucial factor in determining shipping costs for packages. Unlike traditional shipping methods that relied solely on the physical weight of a package, carriers like Purolator use dimensional weight to account for the space a package occupies in their transport vehicles. This ensures that pricing is fair for both lightweight, bulky items and heavy, compact ones. Essentially, carriers charge for whichever weight is greater: the package's actual measured weight or its calculated dimensional weight. Understanding Purolator dimensional weight is key to accurate shipping cost estimation and can help businesses optimize their packaging strategies to potentially reduce expenses.
Who Should Use the Purolator Dimensional Weight Calculator?
Anyone shipping items via Purolator can benefit from using a Purolator dimensional weight calculator. This includes:

Common Misconceptions about Purolator Dimensional Weight
Several common misunderstandings surround dimensional weight:
- Myth: Only large items have dimensional weight. While bulky items are most affected, any package can have a dimensional weight that differs from its actual weight.
- Myth: Actual weight doesn't matter if dimensional weight is higher. Carriers always charge the higher of the two weights. If your package is heavy and compact, actual weight will likely be the determining factor.
- Myth: The dimensional factor is always the same. While 5000 is a common divisor for Purolator, carriers can adjust this factor. It's always best to verify the current factor used by Purolator for your specific service.
- Myth: It's too complicated to calculate. With a reliable Purolator dimensional weight calculator, the process is straightforward, requiring only basic package dimensions and actual weight.
Purolator Dimensional Weight Formula and Mathematical Explanation
The calculation of dimensional weight is based on a straightforward formula that converts a package's volume into an equivalent weight. This is essential for carriers like Purolator to standardize pricing across diverse package types.
The Core Formula
The formula for calculating dimensional weight is as follows:
Dimensional Weight = (Length × Width × Height) / Dimensional Factor
After calculating the dimensional weight, the carrier compares it to the package's actual physical weight. The chargeable weight, which is the weight used for billing, is the higher of these two values.
Chargeable Weight = Maximum (Actual Weight, Dimensional Weight)
Variable Explanations
To accurately use the formula, understanding each component is vital:
| Variable | Meaning | Unit | Typical Range / Values |
|---|---|---|---|
| Length (L) | The longest dimension of the package. | cm (centimeters) | > 0 cm |
| Width (W) | The second longest dimension of the package. | cm (centimeters) | > 0 cm |
| Height (H) | The shortest dimension of the package. | cm (centimeters) | > 0 cm |
| Dimensional Factor | A constant divisor set by the carrier (Purolator) to convert volume into weight. This accounts for air space and handling efficiency. | Unitless (usually expressed as cubic cm per kg or cubic inches per lb) | Commonly 5000 for Purolator (cm³/kg). Other values may exist for specific services or regions. |
| Actual Weight | The physical weight of the package measured on a scale. | kg (kilograms) | > 0 kg |
| Dimensional Weight | The weight calculated based on the package's volume and the carrier's dimensional factor. | kg (kilograms) | > 0 kg |
| Chargeable Weight | The final weight used by the carrier for billing purposes; the greater of Actual Weight or Dimensional Weight. | kg (kilograms) | > 0 kg |
The dimensional factor represents how many cubic centimeters (cm³) of volume equate to one kilogram (kg) of weight for pricing purposes. A lower factor means that volume contributes more significantly to the weight, potentially increasing costs for larger, lighter items. Conversely, a higher factor reduces the impact of volume. For instance, a factor of 5000 means 5000 cm³ of volume equals 1 kg for pricing.
Practical Examples (Real-World Use Cases)
Let's illustrate how the Purolator dimensional weight calculator works with practical scenarios.
Example 1: Shipping Lightweight, Bulky Items
Imagine a small business shipping a decorative pillow.
- Package Dimensions: 40 cm (Length) x 30 cm (Width) x 15 cm (Height)
- Actual Weight: 1.5 kg
- Purolator Dimensional Factor: 5000
Calculation:
- Volume: 40 cm × 30 cm × 15 cm = 18,000 cm³
- Dimensional Weight: 18,000 cm³ / 5000 = 3.6 kg
- Chargeable Weight: Maximum (1.5 kg, 3.6 kg) = 3.6 kg
Interpretation: Even though the pillow only weighs 1.5 kg, it occupies significant space. Purolator will charge based on the dimensional weight of 3.6 kg. This highlights the importance of compact packaging for bulky goods.
Example 2: Shipping a Heavy, Compact Item
Consider shipping a small, heavy electronics component.
- Package Dimensions: 20 cm (Length) x 15 cm (Width) x 10 cm (Height)
- Actual Weight: 8 kg
- Purolator Dimensional Factor: 5000
Calculation:
- Volume: 20 cm × 15 cm × 10 cm = 3,000 cm³
- Dimensional Weight: 3,000 cm³ / 5000 = 0.6 kg
- Chargeable Weight: Maximum (8 kg, 0.6 kg) = 8 kg
Interpretation: In this case, the package is much heavier than its volume suggests. Purolator will charge based on the actual weight of 8 kg, as it is significantly higher than the calculated dimensional weight of 0.6 kg.
Example 3: Close Call – Near Equal Weights
Let's see a scenario where actual and dimensional weights are close.
- Package Dimensions: 35 cm (Length) x 25 cm (Width) x 22 cm (Height)
- Actual Weight: 5.5 kg
- Purolator Dimensional Factor: 5000
Calculation:
- Volume: 35 cm × 25 cm × 22 cm = 19,250 cm³
- Dimensional Weight: 19,250 cm³ / 5000 = 3.85 kg
- Chargeable Weight: Maximum (5.5 kg, 3.85 kg) = 5.5 kg
Interpretation: The actual weight is still the determining factor. This example reinforces the need to consider both metrics. If the actual weight were, for instance, 3 kg, the Purolator dimensional weight of 3.85 kg would become the chargeable weight.

Key Factors That Affect Purolator Dimensional Weight Results
Several elements influence the final shipping cost, with Purolator dimensional weight being a primary one. Understanding these factors helps in managing shipping expenses effectively.
- Package Dimensions (L x W x H): This is the most direct input into the dimensional weight calculation. Larger dimensions naturally lead to a higher volume and, consequently, a higher dimensional weight, assuming other factors remain constant. Careful selection of box sizes is crucial.
- Actual Package Weight: While dimensional weight often impacts lighter, bulkier items, the actual weight remains paramount for heavy, compact shipments. The carrier always bills based on the greater of the two.
- Purolator Dimensional Factor: This divisor (e.g., 5000 cm³/kg) is set by Purolator and can vary between carriers or even service levels. A lower factor increases the impact of volume on the calculated weight, while a higher factor reduces it. Businesses should always confirm the factor relevant to their specific Purolator service.
- Shipping Service Level: Purolator offers various services (e.g., Express, Ground). Different service levels might have different dimensional weight thresholds or factors applied, affecting the final cost. Premium, faster services might have different calculation rules than standard ones.
- Destination and Distance: While not directly part of the dimensional weight calculation itself, the final shipping cost is heavily influenced by the distance between origin and destination. Longer distances generally incur higher base rates, which are then applied to the chargeable weight. Understanding shipping zones is key.
- Fuel Surcharges and Other Fees: Carriers like Purolator often apply additional surcharges, such as fuel surcharges, which fluctuate based on market conditions. These are added to the base rate calculated from the chargeable weight, increasing the total shipping cost. Accessorial charges for special handling may also apply.
- Packaging Material Density: Although not a direct input to the calculator, the choice of packaging materials impacts both the actual weight and the dimensions. Lightweight but strong materials can help keep both values lower, potentially reducing costs. Conversely, overly protective or excessively large packaging can inflate both metrics.
Frequently Asked Questions (FAQ)
Purolator calculates dimensional weight by multiplying the package's Length, Width, and Height (in centimeters) to find the volume in cubic centimeters (cm³). This volume is then divided by a specific dimensional factor, commonly 5000 (cm³/kg). The higher value between this calculated dimensional weight and the package's actual measured weight is used for billing.
While 5000 is the most commonly used dimensional factor (divisor) for Purolator for standard services in cm/kg, it's essential to verify this with Purolator's current official guidelines or your specific service agreement. Carriers can sometimes adjust these factors based on operational needs or specific shipping lanes.
It's crucial to measure as accurately as possible. Slight inaccuracies are usually acceptable, but significant discrepancies could lead to incorrect billing. For consistent results, measure the exterior dimensions of the fully packed and sealed box. Using rounded numbers might be necessary if precise measurements aren't feasible, but aim for consistency.
Yes, dimensional weight principles generally apply to most shipments handled by Purolator, especially for domestic and international parcel services. The calculation ensures that the space occupied by a package is factored into the shipping cost, regardless of its actual weight.
Purolator, like most international carriers, primarily uses the metric system for calculations. This calculator is configured for centimeters (cm) for dimensions and kilograms (kg) for weight. Ensure your measurements are in the correct units before inputting them.
Absolutely. If your Purolator dimensional weight is consistently higher than your actual weight, optimizing your packaging is key. Use appropriately sized boxes, avoid excessive empty space, and consider lighter packaging materials. This can reduce both the volume and the actual weight, leading to potential savings. Proper packaging techniques are vital for e-commerce.
Actual weight is the physical weight of the package measured on a scale. Dimensional weight is a calculated weight based on the package's volume (Length x Width x Height) and the carrier's dimensional factor. Purolator charges the greater of these two weights.
Dimensional weight calculations typically apply more rigorously to individual parcels. For larger freight shipments (LTL/FTL), carriers often use different pricing structures based on density, freight class, and actual weight, rather than the simple parcel dimensional weight formula. However, rules can vary, so it's best to consult Purolator for freight-specific calculations.
