Every warehouse manager faces the same question when implementing dimensional scanning: how many pallet dimensioners do we actually need? Buy too few, and you create bottlenecks that strangle productivity. Buy too many, and you’ve wasted valuable capital that could be used on other areas of your operations.
The answer lies in understanding your throughput requirements and matching them to the right technology. At Cargo Spectre, we’ve helped hundreds of clients, large and small, determine the perfect number of dimensioners for both current and future needs. Let’s talk about the same calculations we share with prospects during a consultation:
Calculating Warehouse Throughput Requirements
The number of pallet dimensioners your warehouse needs depends primarily on daily scan volume. Start by calculating your peak hourly throughput during busy seasons, not average daily volumes. Many operations see 40%–60% of their daily volume concentrated in 3–4 peak hours. Some larger operations? Well, they never stop moving!
For example, if your warehouse processes 1,000 pallets daily with 60% moving through during peak hours, you’re looking at 600 pallets in roughly 4 hours. That’s 150 scans per hour during crunch time.
The top, traditional stationary dimensioners handle 80–100 scans per hour, when accounting for positioning time and operator efficiency. Using our example, you’d need two static pallet dimensioning units just to avoid creating bottlenecks during peak periods.
The Game-Changing Math of In-Motion Technology
This calculation changes dramatically with in-motion dimensioner technology. Cargo Spectre Roll-Thru dimensioners capture measurements while forklifts move at normal operating speed, eliminating stop-and-scan delays. These systems handle up to 600 scans per hour, enough to process that same 1,000-pallet daily volume with a single unit, even during peak congestion.
Basically, Roll-Thru pallet dimensioners eliminate three big time-wasters: stopping the forklift, aligning the load, and waiting for measurement (even if it only takes seconds). When forklift operators roll through the scan zone at full speed, you’re not just saving seconds per scan. You’re locking in operational flow.
Calculating Your Specific Needs
Here are three of the most common types of logistics operations Cargo Spectre assists with:
Small Distribution Center (500 pallets/day):
- Peak hourly volume: 75 pallets
- Traditional dimensioners needed: 2 units
- Cargo Spectre dimensioners needed: 1 unit
Medium-Volume Warehouse (2,000 pallets/day):
- Peak hourly volume: 300 pallets
- Traditional dimensioners needed: 5–6 units
- Roll-Thru dimensioners needed: 1 unit
High-Volume Operation (5,000+ pallets/day):
- Peak hourly volume: 750 pallets
- Traditional dimensioners needed: 12–15 units
- Roll-Thru dimensioners needed: 2 units
Strategic Placement Considerations
Beyond raw numbers, consider placement strategy. Even with high-throughput in-motion dimensioner units, strategic positioning prevents bottlenecks:
Single-Unit Operations: Position your scanner where all outbound freight naturally flows—typically near shipping doors or at the convergence of picking lanes.
Multi-Unit Operations: Distribute scanners based on freight patterns. One near receiving for immediate dimensioning, another at shipping for final verification. This split-operation approach provides redundancy while capturing data at optimal workflow points.
Every Cargo Spectre installation includes our expert placement guidance. Our ultra-adaptable hardware can be adjusted to fit virtually any footprint.
Future-Proofing Your Investment
When calculating dimensioner requirements, we always factor in growth. If your volume increases 20% annually, that single traditional unit struggling with today’s volume becomes a critical bottleneck next year.
Cargo Spectre Roll-Thru dimensioners provide breathing room with their 500+ scans/hour capacity. A system operating at 60% capacity today can absorb significant growth without requiring additional hardware investment. No matter which dimensioner or how many you choose, however, our low upfront costs mean we can always quickly upgrade you quickly without a major capital expenditure on your part.

For most warehouse operations, the formula is straightforward: Calculate your true peak hourly needs, then divide by scanner throughput. The resulting number tells you the minimum units required for smooth operation.
Remember that in-motion dimensioner technology like Cargo Spectre Roll-Thru systems dramatically reduces the number of units needed while improving operational flow. A single high-throughput unit often outperforms multiple traditional scanners while requiring less floor space and fewer operators.
The right number of pallet dimensioners keeps freight moving efficiently while capturing the dimensional data essential for accurate billing and load planning. Whether that number is one or five depends entirely on your specific throughput requirements and the technology you choose.
