The idea behind CoLoCa: Efficient container planning for modern logistics
In times of rising freight costs, scarce capacities and increasing complexity in global supply chains, digital logistics is gaining importance. CoLoCa (Container Loading Calculator) was created to address precisely this: a practical tool that helps freight forwarders, logisticians and exporters quickly and accurately determine the optimal container size and thus achieve efficiency gains and transport optimization.
Why CoLoCa? Background and motivation
The CoLoCa project idea is based on concrete market needs: many companies lose time and money due to suboptimal container choice, unclear volume indications or lack of transparency in utilization. CoLoCa addresses these problems with a clear focus on user benefit:
- Rapid calculation of freight volume in all common units of measurement
- Automatic determination of container utilization for multiple standard container types
- Easy shareability of calculation results with customers and partners
The goal is not a technical gimmick, but practical support for better decisions in daily transport planning.
Challenges in modern container planning
The common pain points in the industry are:
- Different units of measurement and uncertainty in conversions (mm, cm, m, inch, ft)
- Combination of piece goods and bulky goods with different volumes
- Risk of over- or underutilization: loss of revenue from unused space or risk from overloading
- Communication with customers and partners about exact volume figures
CoLoCa solves these issues through a clear, standardized volume and utilization calculation. This reduces planning errors and creates the basis for cost-efficient decisions.
Core functions and benefits for users
CoLoCa offers an interactive container loading calculator with two input types:
- Dimension-based calculation: enter dimensions and quantity, volume is automatically converted to m³.
- Example: Pallet, 5 pieces × (120 cm × 80 cm × 100 cm) = 5 × 0.96 m³ = 4.80 m³
- Direct volume input: enter already known volumes (m³ or ft³); bidirectional conversion is performed automatically.
For six common container types (e.g. 40ft Standard, 40ft High Cube, 20ft Standard, 45ft High Cube) CoLoCa calculates utilization in percent, shows remaining space in m³/ft³ and visualizes the status by color (Green: underutilized, Yellow: optimal, Red: critically full, Black: overloaded).
This information enables quick recommendations, e.g. whether a High Cube is more sensible than a 40ft Standard when tall goods require more space.
Practical tips for better container utilization
- Measure accurately: determine height, width and depth precisely. Small measurement errors add up across many items.
- Choose a unit: work consistently in m³ to avoid conversion errors. CoLoCa supports automatic conversion.
- Prioritize: record bulky goods separately, as they often require special space or loading conditions.
- Check stackability: not every shipment can be stacked. Volume reduction through stacking should be estimated realistically.
- Optimal utilization range: a utilization between 70–90% (yellow) is often economically optimal — enough reserve for securing, but no waste of resources.
Practical example: If the total of all items is 57.93 m³, a 40ft Standard (67.69 m³) with 85.6% utilization is often the pragmatic choice. A 40ft High Cube would provide more reserve, which may be preferred for fragile or tall goods.
Communication & collaboration: share instead of sending screenshots
A major time saver is the ability to save calculations as shareable links. This allows a complete load with all items and utilization data to be passed on to customers, suppliers or warehouse staff. Advantages:
- No follow-up questions due to unclear information
- Unified data basis for quoting and booking processes
- Traceability: shared calculations can be restored and reviewed
Tip: Use the shared links to support offers with concrete container suggestions — this increases trust and reduces renegotiations.
Target groups and concrete use cases
- Freight forwarders: rapid volume checks for customer inquiries, container recommendation in seconds.
- Exporters: optimal container choice before shipping, cost savings through suitable container size.
- Logisticians: warehouse and transport planning with precise volume data.
- Buyers: volume checks before ordering and better calculation of freight costs.
E-commerce shippers and manufacturing companies also benefit from lower error rates and better planning certainty.
Conclusion: Efficiency gains through digital support
CoLoCa is not a replacement for logistics experience, but a practical tool that complements that experience. Through precise volume calculation, clear utilization displays and easy shareability, the tool offers real added value for daily transport optimization. Those who want to make container selection, offer creation and communication more efficient gain time, reduce errors and lower costs with CoLoCa.
Short checklist for use
- Measure items accurately and record quantities
- Use the volume or dimension input depending on prior knowledge
- Pay attention to the color utilization display (Green/Yellow/Red/Black)
- Share calculations with customers via links for better coordination
- Check whether High Cube vs Standard is economically sensible
CoLoCa connects digital logistics with pragmatic benefits — for more efficient planning, clearer communication and fewer empty miles in your supply chain.
